【正文】 A1 on behalf of A, No. 1 shaft fed a distribution box. Fed a lowvoltage circuits, such as the number of uses: W36AL1A1, W36) indicates that the route back to power supply transformer 3, 6, feed the power distribution cabi, AL1A1, said the then the first loop of the distribution box for the AL1A1 and so on, and so on. 10 Conclusion With more and more plex mercial design projects, designers need to continually improve the design level, designed to make fine. These are only bits of the design in the business lessons learned, and the majority of designers want to municate 。 BI on behalf of the basement。 shortings is a higher cost. BA system control advantages of using low cost, simple control。 current transformer for the 1000/50。 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 conductors must be considered in a certain margin to meet the needs caused by adjustment of the load changes. According to this characteristic, increased use in the design of the plug buspowered, not only meet the requirements of large carrying capacity, and also allows the flexibility to increase supply and distribution, are reserved in each shaft in the plugbox backup in order to change, according to changes in upper and lower
