systems distribution electrical

task systems distribution electrical installations industrial is the most important terms design optimization networks nutrition electrical installations industrial in the provision of ululate high-taking into account the economics of the quality of electricity the network, and determine the economics of the system by reducing the annual cost and will depend level ululate feeding on class ululate pregnancy electrical properties the production process, the result in appreciation is the exact these data are either to reduce ululate system, nutrition and either to increase unnecessary and hence the cost of a high. Overall it on the designer study of a number of synonyms system, nutrition and chooses أنسبها through the feasibility studies of art / economic. 1 nutrition electrical (a) prerequisites: design systems nutrition electrical installations industrial there prerequisites should be aware of and are: - quality established and demand for electricity (type stream - effort - العول ..... and so on). - the properties of surrounding environment. - the expense of loads electrical groups consumers of electricity and determine the effort appropriate told the nutrition entity. - determine the number and ability and type the optimal adapters power station Transformers key adapters distribution. - link station Transformers home and distributor of the main. - scheme equipment distribution on high voltage station Transformers home (distributor main) and quality stalls Transformers. - the expense of streams Palace and choose equipment pieces and prevention in the network medium voltage. - the expense of streams Palace in the network low voltage and choose the protective equipment والقواطع. - the design of a network low voltage. - chosen system point tie بالورش according للخواص technological consumers of electricity. - the expense of system grounding station Transformers home and distributor of the main stalls Transformers, as well as the expense of preventing stations of increasing efforts trans. (To) additional requirements: there are additional requirements -طبقا the nature of الأحمال- can be summarized as follows: - the study of the quality of electricity and procedures to ensure maintain quality in the limits of standard specifications. - make up the ability ineffective. - the expense of energy consumption of electrical and procedures to ensure reach out to the rates of consumption standard. - reduce the loss of power and selection methods means so. - study ululate system, nutrition and electrical and calculate the loss caused when power. - study of the operating incomplete face the system and calculate the impact on the work of the engines electrical. - the study of the start of the movement of the engines electrical impact on the system, nutrition and electrical. - the organization and preventive maintenance of equipment electrical. - the study of control and measurement remote system, nutrition and electrical. (A) the requirements of the feasibility and safety: include: - the feasibility of art / economic system networks based equivalents equipment and electrical used. - the procedures required to provide security during the installation of the equipment electrical system nutrition electrical and requirements resistance fire and keep established. 2 basic data to select your networks النغذية must provide the following data: - plan year property industrial indicating the sites workshops and methods of transport internal spaces Green, pipes, underground buildings and the other. - properties of technology for production facility, workshops and various estimates the effect of power to the production process. - loads electrical workshops in the image installed capacity (ability inhalers coefficient ability and efficiency. And effort rated) at each time duty cycle of equipment operating system running frequent. - curves loads (effective and efficient) property, workshops and various during business days summer وشتاءا. - the properties of energy consumption of electrical and its impact on the quality of energy electrical. - scheme sites equipment بالورش data and properties of the environment بالورش (level burning building materials and buildings and moisture air presence chemicals effective .. and so on). -البيانات following from sources nutrition electrical available for property: 1. (plants or stations adapters) and capabilities. 2. impedance source nutrition and the ability of the Palace on bars source or capacity of the pieces لقواطع the source. 3. the effort to bars source nutrition. 4. the ability of available from the source entity. 5. the distance between the source of nutrition established. - the amount of the ability ineffective are available from sources nutrition entity's in my case pregnancy maximum and minimum. - in the case of rehabilitation system, nutrition an existing facility must provide plan the system and data equipment and electrical used and type of sizes and connectors and cables and bars. 4 choose the sources of nutrition is stations generation networks connectivity and distribution of electricity sources nutrition home facilities industrial. In the case of a private collections of loads electrical (furnaces bow electrical .. for example) or insufficient the ability of the main source, are building plants private facility which is determined by a capacity of purpose of its inception and can swing in the limits of a wide, and adopt this stations of type warming in facilities بأحمال thermal big is determined by the site optimized to build a station obstetrics own in the Center of the loads electrical, and in the case of match the Center loads electrical with site a buildings production or the Center of the movement of transfer internal is moving the station obstetrics special to the site as close to be from the Center of the loads electrical. In the case of industrial facilities بأحمال the category of "ululate a preliminary" must provide exporters independent at least for nutrition. It is considered all of part-rails divided or a group of groups system bars a stations generation or stations adapters source feed independent in the case of feeding each of the source of feeding independently with her automated system 2 of 3. also considered stations generation of facilities industrial sources feed independent in the case of non-linked to the network standard or in the event processing link to work with the station and network system 2 of 3. 5 choice network nutrition home divided facilities in accordance with the ability vehicle to facilities large (75 mega Watt and more) and systems medium ability (5-57 mega Watt) and facilities small (up to 5 mega Watt) and in general, the network nutrition home facilities small and medium-ability designed Center one to receive the electricity (station adapters major or supplier major), and in the case of the presence of loads the category of "ululate a preliminary" break up bars station reception and nutrition every part of the line of independent designed network nutrition home status of receivers or more facilities industrial large capacity that are most أحمالها category "ululate a preliminary" and in the case of a group loads large capacity and the nature of private or when the development of established on stages it may be الأجدى economically feed group loads the next phase of the status of receivers separate especially when you centers reception my job conversion and distribution of the internal network. In facilities medium and large capacity and receive nutrition of network connectivity (66 as F.), transport, (220 as F.) must be expanded the use of systems nutrition deep featuring the arrival of high voltage to as close as possible to centers loads, where penetrate the lines of nutrition deep the limits of created and graduated from تفريغات to several stations adapters feed deep take place near the centers loads, in general, the stations adapters nutrition deep adopting بمنظومات simplified without breaker or bars on high voltage is made up cheaper systems nutrition deep only of knives grounding and knives separation of pregnancy on high voltage. And distribution of the energy of electrical equipment distribution of effort average module and builds nutrition deep in the form of lines, bags key)-or in the form of lines of radioactive air or cable أرضية-). Implemented nutrition deep lines air high voltage in environments normal and low pollution, used cables the floor in the air most polluted, characterized systems nutrition deep radiative flexibility and ease of operating compared بالمنظومات with guidelines as the slip-up or repair a lines or Transformers does not affect the work stations Transformers the other. Choose station Transformers home designed station Transformers home in accordance with the ability vehicle entity ومستوي ululate Fed and quality of loads and distribution within the limits of created as well as in accordance with the requirements of production systems operating in general, the station Transformers home include adapter one or several adapters and equipment pieces on high voltage, medium and simpler stations and those that has no cutting tools on high voltage where the adoption of these stations of units built (adapter integrated with knives chapter on high voltage) can be used at all efforts. When it is impossible to the use of the units compact without breaker and rods are designed stations Transformers home set one of the rails fragmented on high voltage - used stations Transformers home-containing breaker on high voltage in rare cases in stations high capacity, which contains many of the nutrients go out and enter a comprehensive lines trans and become these stations high cost in the case of the provision of my group bars on high voltage add to complicate systems running in order to provide more flexibility in the work of chapter والتعشيق, adopting stations main system bars major وأخري transition, However, this kind of plants is common to use facilities industrial and spreads in stations Transformers large areas where contain large numbers of nutrients in and out. Spread the use of systems rails fragmented on medium voltage at stations Transformers home - depends the number of parts rails on the number of nutrients entry and exit system and the distribution of the strong electrical onsite and in most cases, no more than the number of parts rails for a two-part where works every part separate in the case of the operating normal nourishes of line or adapter independent. Operates the station with rails split system 2 of 3 automatically allowing for use in the industrial facilities in any level moan, and is noteworthy that the simplest systems and least cost contain bars is fragmented, However, this system used in feeding the loads electrical the category of "ululate a third" so that when a Palace on rails or when the maintenance cut off power for all loads the station. And choose the number adapters strong and ability inhalers her station Transformers key adapters distribution Porsche established on the basis of art / economic order لتأثيرها great to the economics of networks nutrition electrical entity's industrial the main indicators choose Transformers in ululate nutrition and electrical is determined by synonym optimization by comparing the investment cost of the annual for several synonyms and even run systems nutrition electrical smoothly and should focus on the selection of not more than قدرتين مقننتين Transformers home (other than adapters service) resulting in a few stockpile facilitate the process bring Transformers corrupted and best - whenever أمكن- use adapters a capacity of uniform. 7 choose the distribution networks the interior of the properties of distribution networks internal frequent تفرعها, management on large numbers of hardware prevention affecting heavily on technical indicators and economic وعول systems nutrition electrical to build the distribution networks internal is optimal must take into account: figure executive centers home network path electricity currents Palace through the preparation of a number of synonyms to design the network and must be interested in the designer providing solutions suitable to feed the loads strong and lighting at night in the holidays and holidays in order to achieve the Reserve mutual recommend the provision of bridges bars and cables between stalls workshops very competitive as well as between المغذاة of Transformers the distribution of different. (A) the foundations of public to choose distribution networks interior in general condition of the adoption of distribution networks secondary several stages, but it is worthwhile building systems and networks by more 2-3 stages of the distribution in order to avoid the complexity of you agree equipment pieces and prevention recommends building networks stage the distribution of one facilities industrial with the ability of a vehicle small. Must be linked to design distribution networks system production technology property by feeding the loads electrical production lines of parallel of independent sources so as not to stop error production at a exporters of nutrition and feed production equipment correlated of the source of feeding one to ensure that stopped all at the same time when the separation of nutrition electrical. And when the implementation of distribution networks internal entity's industrial must review synonyms achieve optimal use boards distribution and less length لمغذيات network وأقصي economics of equipment pieces and prevention. (To) choose the distribution networks internal facilities industrial adopting distribution networks secondary entity's industrial either system nutrients home or system radiation or mixture of المنظومتين are choosing the system according لعول loads of electrical and locations on the chart year property characteristics system operating. In a systems radiation transmitted electricity directly from the source of nutrition to the consumer often implement these systems stages of the distribution of no more than two-stage in the industrial facilities SME adopting systems distribution of radiation stage the distribution of one-feeding the loads الممركزة scattered in all directions from the Center of nutrition and check systems distribution of radiation fragmentation deep for each system, nutrition and electrical beginning of the source of nutrition and ending bars low voltage in stalls adapters workshops -.و feed stations Transformers والموزعات بأحمال the category of "ululate a preliminary" two-line إشعاعيين at least خارجين of part-bars source nutrition and nourish stalls Transformers (400 - 630 as in a) the scattered away from the source of nutrition with the absence of loads electrical the category of "ululate a first and second" بمغذي radioactive one without a Reserve with warranty repair quick للمغذي provide way to opportunity to extend the cables for workshops بأحمال the category of "ululate a second" فتغذي by مغذيين parallel with the provision of سكينيتين per cable. Use networks of radiation بمرحلتي distribution in the construction dispensers interfaces in distribution network industrial facilities large and medium-where feed centers loads the big through dispensers - - if not feasible download Center nutrition main entity component of the cells of the distribution of expensive in large numbers of nutrients out a few loading and nourish stalls adapters workshops of spreaders intra without bars on medium voltage is delivered cable or through knife separation of pregnancy with saving devices pieces and prevention inside distributor. Use the distribution networks بمغذيات key in the case of the large number of centers loads and not the feasibility of using the networks of radiation and is feature is essential in networks بمغذيات key in the lack of the number of sites chapter والتعشيق increase the feasibility of these networks when spread stalls Transformers square-established in the lines network straight allowing tide direct cable for the main source of nutrition to stalls shortest roads. يعاب on networks بمغذيات major low عولها compared networks of radiation because of lack of the possibility of the provision of systems back-up to low voltage للأكشاك single-converter when Fed of nutrient one major recommends not to feed more 2-3 stalls adapters (1000 - 2500 as in a) or more of the 4-5 booth adapters (250 - 630 as in a) of nutrient one major ولرفع ululate networks بمغذيات key is developed to one of figures the following two in accordance with لعول malnutrition the investigator: - networks multiple nutrients home without a Reserve for feeding the loads the category of "ululate a third" -). - networks multiple nutrients home overlapping of العول high to feed the rest of categories العول -). Prefer networks two-of nutrients home overlapping to feed the stalls Transformers بالورش or spreaders bars fragmented fdr2, fdr1 - or stalls workshops remote Transformers without bars on medium voltage fdr4, fdr3 -. Works part bars booth Transformers or distributor separate in the case of the operating normal. In the case of a failure to any of the stalls Transformers on enriched main or dealer movement of Fed to nourishing the main remainder of service. In the design of actual slightly used as the shape of radiation only or shape بمغذيات master only but using a combination of both to take advantage of the advantages of their respective in building system, nutrition electrical the top of the feasibility of art of economic. 8 choose networks nutrition electrical بالورش (low voltage) adopting networks workshops facilities industrial on the efforts of up to 1 kilo F. (380 F. is an effort most common) is the most important factors that affect to choose systems and networks, workshop level العول required for feeding the loads-systems عملها- their locations within the limits of the workshop - the values of the current - efforts inhalers there is especially important environment buildings production that تقسمها standard specifications in accordance with properties surrounding environment to the buildings atmosphere moderate, hot, wet wet, wet strongly, dusty, effective and chemically, areas are subject to fire and blast. Divided networks workshops to networks بمغذيات major وإشعاعية ويسمي nutrient networks workshops the outside of the cell distribution low voltage on secondary adapter distribution dedicated to feed the loads ممركزة large or distribution network inside workshops بالمغذي main designed nutrients home capacities great until 6300 amp and come out of them a lot of التفريعات in the stalls Transformers containing محولين link sets adapter nourishing the main by bridges بقاطع electrical savings Reserve mutual, made up systems nutrition radiation from a set feeders network workshops electrical which come out of a cell distribution low voltage on secondary adapter is dedicated to feed the numbers of a few of the loads scattered in various sites workshop and used systems distribution of radiation workshops at could not be used systems بمغذيات key.
