摘要
针对某电厂脱硫电源接线,开展供电可靠性和机组安全性分析,找出电源设计存在的不足,重点针对6 kV电源不能自动切换问题、380 V欠压脱扣器故障率高问题进行了整改,确保环保设施和机组的安全稳定运行。
Aiming at the desulfurization power supply wiring of a power plant,the reliability of power supply and unit safety analysis are carried out to find out the deficiencies in the power supply design.The rectification is focused on the problem that the 6 kV power supply can not be switched automatically and the high failure rate of 380 V under-voltage tripper,so as to ensure the safe and stable operation of units and environmental protection facilities.
