The district covers an area of large, population is concentrated. Load capacity, electrical equipment, especially in electric load peak season, overload tripping off, if the mains supply circuit breaker tripping caused by large area power outages, will give residents living inconvenience, so must adopt new ideas and ways to meet the needs. The power supply design load, switching capacity, wire section, the configuration of transformer capacity for the analysis, and proposed should pay attention to the problem.1.residential supply and distribution characteristicsThe area of the building space between the large power supply area is larger, each box power supply range is limited, therefore needs a plurality of box transformer can meet the requirements of the user load. Due to many users, power supply circuit must have a corresponding number. The number of each floor area of the building and the user is not the same, not the same way of power supply according to the number of households, to take power accordingly. For conjoined buildings can be adopted as single-phase, three-phase power supply can be used for the penthouse floor. Lighting load for users living electricity, but the air conditioning 1load for the comfort of electricity. Due to the small area is large, the load points and scattered, so in the construction. The power supply uses the two PSA, the first level is 35kV 10kV (station second grade 10kV), to 0.4kV (outdoor box type transformer). Box distribution in the load center, reduce the one-time investment, reduce operating costs, improve the user The electricity quality. From the station to the 10kV with a cable connection box, each box transformer capacity calculation of the total load selected by each group into the family of single buildings.2.residential supply and distribution facilities statusWith the continuous improvement of peoples living standard, household electrical appliances especially air conditioning, electric rice cooker, microwave oven, such as high power, low power consumption much with electric equipment gradually in the ordinary family in use. Along with the residents with the load increasing, residents living in the area of the power supply facilities cant meet the needs of residents electricity load growth, there exists the following problems:Some real estate developers only consider their own interests, to save money to provide backward distribution equipment selection, insufficient capacity of the transformer configuration, construction standards lower, extended lines operation and variable loss, bring unsafe hidden dangers. Outdated power distribution equipment, need to be upgraded. Even in the initial stage of development, less capacity. Due to the presence of a power supply contract relationship between power supply companies and property companies, and with no legal binding contract between the residents of electricity, once the individual residents of arrears, the power supply enterprise is difficult to take effective measures according to law tariff collection. Within the district is very difficult to find a suitable place to re build a variable power distribution room, to meet residents living electricity load growth needs. Transformer capacity within the district are generally too small, the original design capacity is only according to meet residents living lighting electricity load considering, so to be augmented. Some small variable power distribution room area generally smaller. Cant satisfy the need of transformer capacity increase and transformation equipment. 2Between owners and property companies contradictions become increasingly prominent with increasing the amount of area residents.3.the social requirements for residential area power supplyThe rapid development of social economy, people gradually raise the living standards in Tangshan Lugang area as an example, in a household, household appliances increasing, fast and convenient, clean and sanitary appliances division, growing fast and convenient, clean and sanitary or electric energy is gradually replace other energy sources. Especially the high energy consumption of the air conditioning, refrigerator, electric water heater, electric cooker, regenerative electric heater, electric boiler heating equipment, audio equipment, luxury chandelier was very popular, with 2 to 3 air-conditioning, color TV, refrigerator family has W see with fresh if residents in the implementation of preferential tariff cascade power supply enterprises. Driven by a large number of electric energy consumption growth so if this. To plan ahead. The principle in the design of power supply for the residential areas, for the electrical equipment will be added to leave some room for load. In this way, we can make free uninterrupted updates for Electric equipment, reduce the unnecessary duplication of investment and frequent changes to bring users inconvenience.4. residential electricity load and power distribution design problemsThe distribution design, as part of a part can not be replaced, such as: the way of indoor distribution of each household, wire section of the buried pipeline, the room of the socket. The other part is to replace the parts, such as power supply transformer units (or capacity), 9 meter 4 rate table, into the family line and the power supply line. The electricity meters and open loop to the indoor distribution box, with lighting, air conditioning and other electrical socket three circuit is the basic circuit, in addition to the above three loop, there should be according to local conditions and engineering requirements of additional electric appliance for kitchen and bathroom special circuit, electric water heater dedicated circuit first. The task is to design for the distribution of electricity load and power load statistical categories, and then load calculation.4.1. the electricity load problemThe current residential area usually has no central air conditioning. Edifice, therefore, residential 3electricity only residential load forecasting is relatively simple, for example.The type of building a district divided into high-grade apartments, underground garage and ancillary boiler room, electrical and so on. On the ground, underground total construction area of about 140 thousand square meters. The apartment area of about 110 thousand square meters, underground garage area of about 30 thousand square meters. The area needed to build 10kV from a substation from the power supply, power supply bureau 1lOkV substation. The requirements of party a household with a total power capacity of 8.5kW (about 35 45W, M2), air conditioning system for household central air-conditioning, household is about 3 5.0kW, household lighting load of 3.5 5.5kW, according to the transformer load rate of 70% (economy) calculation, the total substation the load is 6636kVA, preliminary calculation of residential transformer installation capacity should 6400kVA. the requirements of Party A to improve residential lighting load level, mutual investment with dual power supply. In the non fire case should ensure that the apartment lighting power supply normal. After calculation in power monitoring system for For the reliable guarantee of the premise, take full advantage of the transformer overload capacity can be packed in a 4 * 1.25ookvA. If the electrical load of residential users to continue to grow, power supply cable, resident units and distribution device and wire will face serious difficulties, so the planning and design of the electrical advance awareness is very necessary, the technology of the residential tenants of distribution facilities need continuous transformation. How to choose power supply must be combined with local departments of electric power supply system planning to deal with.4.2.power supply and distribution system for the distribution of small capacityBecause of the frequent growth of household appliances and the use of electricity load increased rapidly, leading to the distribution line, the electrical load breaker and meter can not match the rapid growth.4.3. the power supply lineIn recent years, the rapid growth of household electrical load, households in the distribution line, electrical energy table and circuit breaker, the frequent occurrence of the fault and trip, some households own replacement in high capacity circuit breaker or the short circuit, force the use of air conditioners, cooker, microwave ovens and other appliances. As a result, indoor and outdoor wire severe fever, accelerate the aging of insulation, eventually short-circuit accident occurs, even 4caused the fire.From residential areas for distribution design analysis, determine the ultimate load capacity, if change dark wheat wire is relatively easier. Distribution once identified cannot change the. In real life, if less socket in the room, household Jiezhuang multi-purpose socket and the zero line or all rooms only a socket or a combination socket, is clearly unsafe and unreasonable, but also affect the appearance. In order to ensure the safety of users, and the end of the load power switch should be adopted and disconnect switch phase and N lines of the bipolar electrical isolation.Residential electrical design, wire basically use copper core insulated wire wear pipe or cable dark enough design, threading pipe with flame retardant performance requirements of PVC pipe or welding network management, non conductor (containing protective wire sleeve) buried wall laying, wire section size, mainly user electric meter box before the trunk should pay attention to the development of margin (15-20 years), is generally 4 6mm l copper core insulated wires, user electric meter box to the room of each branch conductor section generally 2.5mm L, lighting special paths available 1.5mm L, electric kitchen with special branch should make the choice according to the specific requirements of engineering.5.the problems and methods that should be noticed in design of residential distribution system5.1. household distribution system terminal loop configuration residential electrical design to coordination local actual situation, consider the development of residential household appliances, that service principle, set reasonable or reserved electrical facilities, ensure orderly residential design.1.lighting circuits and circuit socket set separately.2.determine the use function of the socket independent circuit.3.bedroom living room, each with three single-phase two-wire line combination, socket 2 3; kitchen and bathroom with two plus three dark combined socket 2 group.4.household ammeter (IC card meter, carrier table), distribution box located outside the three-phase five wire system, indoor should introduce the independent circuit 380V dark socket 1, used in electrical equipment by 380V three-phase power supply.5. Air conditioning outlet selection switch 15A or 16A socket installed in the living room and the 5chef room each, general bedroom some also set air conditioner with socket.5.2.main distribution wayIn accordance with the provisions of national standards and relevant departments: by areas of public power supply of 220V lighting load, line current less than or equal to 30a, the single-phase 220V power supply, greater than 30 penetrating inch should use 380V / 220V three-phase four wire system to supply the power. Residential cell line to calculate the current greater than 30A should be adopted when the three-phase power supply and try our best to keep balanced three-phase. Multi-storey residential (determined for three load) should be with trunk radiation power high layer residential, multi-storey residential (identified as a, secondary load) should be the trunk loop.5.3. protection and equipotential connectionThe residential power supply system should use the TN - C - S, with four core armored cable into the building inscribed box, bamboo box after the PE line and N line are strictly separated. Protective earthing and lightning protection grounding common grounding device, grounding resistance with less prevail. Grounding in general the potential connection between health to do local equipotential connection, can reduce the expected contact voltage, reduce the risk of leakage protection devices are not reliable. The total equipotential connection can eliminate electromagnetic interference on the weak system, the security of the computer. The specific method is building general equipotential connection line and line line protection, grounding trunk or main earthing terminal and the heating system of gas pipeline, gas pipeline, into the household, tap water and sewage pipes, building components such as metal conductors connected.5.4. the household terminal distribution by way of the three-phase five wire systemDistribution mode of terminal of the resident should adopt the three-phase five wire (including PE) is the future trend of domestic distribution. Some high-power electrical appliances manufacturers taking into account in the design of the three-phase power supply 380V, is conducive to the power supply system of three-phase load balance, improve the efficiency of wire section and wire. To reduce energy consumption. The power supply circuit has a corresponding number must be within the district. Each building adopts two-phase or three-phase power supply. According to the number of households in each building, take the power mode accordingly. The development area is divided into blocks according to the layout of the single building and load capacity, distribution 6group box becomes the center of the formation. The lighting distribution box, with each layer in each case, single-phase power supply voltage 380V. Avoid line in each layer to prevent misconnection line burn of household appliances.5.5. the rational allocation of powerResidential street lamp, lawn lamp power supply substation by the district (a substation) complex, and centralized management. Fire pump power from the two box provided, the area of the cable network to do with the direction of the path of the cable in a cable trench, select the shortcut path, along the small road - side, and weak box separately. In order to save investment and convenient construction. For the safety of tenants, secondary lightning wave surge protective device on the cable network and the building.5.6.select the appropriate substationDetermine the type of substation, must be combined with the local actual situation of technical and economic comparison is reliable. The selection of rated voltage suitable for box type transformer and transformer is very important, if the area is small, can be installed near the load center place, so as to shorten the supply radius of the feeder line, reducing the line the voltage drop and the power loss and improve voltage quality. And you can control the temperature in the box, each box. Moderate box type substation constitutes an independent system, flexible combination method. The investment cost is saved, and the installation is simple, the power supply quickly, in the case of do the installation base, generally only a few hours can be installed for power supply, to ensure timely electricity the lives of residents.Some problems needing attention in the design of box substation and power distribution unit minimum fire rating for the secondary, box type substation box inside a system using unit vacuum switch cabinet structure, each unit are used specially designed aluminum decorative door structure, each partition hind are equipped with double door panels, l-I-J can be opened, therefore in design work, if main transformer with outdoor arrangement, the proposed main transformer between the box body and minimum fire interval 10m, to ensure the safe operation of the substation.5.7.configurable power monitoring systemIn order to ensure the consistency of the whole area of power data acquisition. The flexibility and load control of the high tunability in every single building is arranged in the electric power monitoring system. The hardware module of the system using the power monitoring system can 7realize the control, improve the safety and reliability of the whole system. The bus can save the cable and the cost of the project. Control layer and layer of mutual investment between air conditioning lighting distribution box, can monitor the whole building lighting, air conditioning and power of the current analog quantity and switch state, statistics, analysis of the entire load. When a closed bus or line power alfunction, it should be a closed lighting load bus switching to another closed bus. Control power monitoring system, which can ensure the reliability of power supply and high power levels, reduced the work intensity of the property management department. If can take power Monitoring system of energy conservation, energy efficiency is objective, but also will increase the investment cost.5.8.lightning protection and equipotential connectionLightning protection practices (1) of the multi-storey residential: mul
