摘要
论述了济钢供电系统因受短路和雷电过电压而引起母线电压瞬时降低对风机、空压机、水泵、轧机等重要设备的影响。介绍了采取延时失压保护装置,提高设备可靠性运行的具体方法。
The power supply system of Jigang Group Co., Ltd. was affected by short circuit and lightning overvoltage, resulting in damage of blower, air compressor, water pump, rolling mill and so on due to instantaneous reduction of bus line voltage. The voltage loss time delay protection was adopted and the device could increase reliability of equipment oper- ation.
