【正文】 determine parameter index within the unit area of shops is also very important and plex because there is no clear indicator of the specification can refer to。 will be in the same city, different regions have different consumer groups . 3) the need to factor in the choice: parameters determined, the need for load calculation. Need to factor monly used method, the calculation will not repeat them. Need to explore is the need for coefficient selection, which in the current specifications, manuals and the unified technical measures is also not clear requirements, based on years of design experience that most end shops in the distribution or level within the household distribution box with case Kx generally take a while, in the calculation of the loop route to take to , the distribution transformers in the substation calculations take to . 3 substations set Load calculation based on the results of this project the total installed capacity of transformer , after repeated consultations with the power pany, respectively, in the project in northern, central and southern three sections set the three buildings into three power substations, 1 set 6 sets transformer substation, take the northern section of power supply。 3 substation located 2 units plus 2 units transformers, take the southern section of A, B two office supply. 10Kv power configuration of this project into two points, each at the two 10Kv lines, the power pany under the provisions of 10Kv power capacity: maximum load per channel is about to , two is the , design 1 , 3 bination of a substation 10Kv, power line, with a total capacity of 。 in the bus and the transformer circuit breaker according to the choice of the general framework of values to select . For example: Route certain equipment capacity 530Kv, Kx take to calculate current of 704A, select the frame circuit breaker is 1000A, tuning is 800A。 bus carrying capacity for the 1000A, this road can meet the maximum 1000A current load requirements, even if there is adjustment, power distribution switches and circuit can not make big changes. 6 layer distribution box set According to the division of layers of fire protection district, respectively numbered as A ~ K layers within the set level shaft for the retail lighting power distribution box, with one on one power supply shops in radial power. Should be noted that the forms of the plex layers of layers of fire partition, does not correspond to the lower, making some of shaft power in charge of the fire district at the same time, also responsible for the power supply adjacent to the fire district. At design time, using the principle of proximity, while also taking into account the burden of the whole trunk load conditions, so that each shaft as far as possible a more balanced load. 7 public area distribution box set Taking into account the future needs of the business redecoration of public areas must be reserved for power. Here the design needs to consider the following points: ① question of how much reserve power, lighting and electricity, which according to GB500342020 Architectural Lighting Design Standards table of Article and , mercial building lighting power density value, highend
