对高层民用建筑电气设计来说,确保消防水泵等一类用电设备的可靠供电及其控制回路的合理设计是至关重要的。通常高层建筑消防水泵均为一用一备,对其控制回路的设计,应满足如下要求:接线力求简单,运行可靠;能手动、自动进行操作;在自动位置时,运行泵和备用泵应能自动进行切换;能正确显示水泵的运行状况等。《建筑电气安装工程图集》(水利电力出版社出版,1987年8月第一版)中有关消防水泵的控制接线图,尚有不合理之处,需要加以改进和完善。下面以《图集》中消防水泵“XF05型控制装置原理接线图”
For the electrical design of high-rise civil buildings, it is of crucial importance to ensure the reliable power supply of a class of electrical consumers such as fire pumps and their control circuits. Fire pumps are usually high-rise buildings are a useful preparation for its control circuit design should meet the following requirements: wiring for simple, reliable operation; manual, automatic operation; in the automatic position, the operation of pumps and spare pumps should be able to Automatically switch; can correctly display the pump operating conditions. There is unreasonable wiring in the control wiring diagram of the fire pump in “Building Electrical Installation Engineering Atlas” (published by Water Power Press, 1st edition, August 1987), which needs to be improved and improved. Below the “Atlas” in the fire pump “XF05 type control principle wiring diagram ”
