【文章內(nèi)容簡(jiǎn)介】 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。 2 4 transformer substations located, plus 6 sets transformers, take the middle of the power supply, in addition to 5 Taiwan highpressure water chillers (total )。 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 。 2 substation transformers and 10Kv, 10Kv chillers sharing a power line, with a total capacity of . The design of the substation layout, in addition to meeting regulatory requirements, it also need to consider the highpressure cabis, transformers and low voltage power supply cabi by order of arrangement, especially in low voltage distribution cabi to feed the cable smooth and easy inspection duty problems are not seriously consider the construction of the cable crossing will cause more long detour, a waste of floor space, and convenient inspections and other issues. 4 small fire load power supply In the design of large mercial projects often encounter small fire load of electrical equipment and more dispersed distribution, if fed by a substation, a substation will be fed a lot of lowvoltage lowcurrent counter circuit breaking capacity circuit breaker and conductor of the dynamic and thermal stability in a certain extent. According to GB500451995 fire protection design of tall buildings, rule should be used in Fire Equipment dedicated power supply circuit, the power distribution equipment shall be provided with clear signs. Interpretation of the provisions of the power supply circuit means from the lowvoltage main distribution room (including the distribution of electrical room) to last a distribution box, and the general distribution lines should be strictly separated. In this design, the use of methods to increase the level of distribution, that is different from the substation bus segments, respectively, a fire fed a special circuit, set in place two distribution cabis, distribution cabis and then the resulting radial allocated to the end of the dual power to vote each box, so that not only meets the specification requirements for dedicated power supply circuit, but also to avoid feeding the substation level of many small current loop. 5, the choice of circuit breaker and conductor Commercial real estate projects use the room as the uncertainty in the choice of circuit breakers and conductor
