Low voltage power distribution system design is the key part of high-rise building electrical design. Its design is related to all aspects of the building's electricity. As the power source of the whole building, the low voltage power distribution design quality is directly related to the realization of the function of building system. Especially for high-rise building, once the low-voltage distribution system design is unreasonable, private pull disorderly pull will cause great potential safety hazard for the building. For high-rise building, there are more and higher requirements for the supporting electric equipment, especially for intelligent building, whose distribution system is inseparable from the support of power distribution system. Because the electrical equipment of high-rise buildings is complex, its power distribution system design also becomes extremely complex. The essence and core to ensure the safety of the power of the high-rise building is to ensure the safety of low-voltage distribution system. A system is intrinsically safe only when it is safe right from the design.%低压配电系统设计是高层建筑电气设计中的最关键部分和环节，其设计关系到整个建筑的用电的各个环节。作为整个建筑的动力源，低压配电设计的好坏直接关系到建筑系统各个功能的实现。尤其对高层建筑一旦低压配电系统设计的不合理，施工中私拉乱扯形象比较突出时往往会对整个建筑产生较大的安全隐患。对于高层建筑来说，其配套的电气设备和功能有更多更高的要求尤其对智能化建筑来说其更是离不开配电系统的支撑。往往高层建筑由于其用电设备多样复杂导致其配电系统设计也变得极为复杂。要保证高层建筑的用电安全其实质和核心是保证低压配电系统的安全。而一个系统只有从设计上做到安全才算是本质安全。
