摘要
辽宁调兵山煤矸石发电有限责任公司1号机组1B一次风机变频器出现重故障,造成锅炉BT,通过查找故障原因,揭露出厂家设计缺陷导致驱动故障误发跳闸信号,并提出优化“驱动故障保护灵敏度”整改方案,抑制误发故障信号,保证高压变频器设备安全运行。
The 1B primary fan frequency converter of Unit 1 of Unit 1 of Coal-fired Power Generation Co.,Ltd.in the Liaoning Diaoshan Coal-fired Power Generation Co.,Ltd.has a heavy fault,which causes the boiler to be BT.By finding the cause of the fault,it is revealed that the failure caused by the design defect of the manufacturer causes the drive failure to cause the trip signal to be misfired,and the optimized"Drive failure protection sensitivity"rectification scheme is put forward.And the false alarm fault signal can be suppressed to ensure the safe operation of the high-voltage frequency converter equipment.
