综合管廊电气工程若干问题的探讨

Study on Several Problems of Electrical Engineering of Utility Tunnel

分析综合管廊电气设计、施工及运营管理中存在的若干问题,针对供电电源、排烟风机供电、配电结构优化、接地、电容电流补偿、电缆支架选材、电气设备防潮、缆线火灾监测、巡检及通讯网络等方面问题进行讨论,给出各问题的解决方案,并在优化综合管廊电气设计及完善管廊功能方面给出了建议。

Several problems existing in electrical design, construction and operation management of utility tunnels are analyzed. A solution to each problem is provided after discussion on the problems such as power supply, power supply of the smoke extraction fan, optimization of the distribution structure,grounding, compensation of capacitance current,material selection of the cable rack, moisture protection of electrical equipment, fire monitoring of the cable and wire, inspection and communication network, and proposals for optimization of the electrical design of utility tunnels and improvement of the tunnel function are presented.
