摘要
燃机启动在低转速下,LCI (LS2100e)隔离变压器的断路器(52SS)断开且无任何故障报警,LCI随后检测到52SS断开后将LCI停机,导致燃气轮机启动失败。介绍了LCI装置在低转速下偶发跳闸隐患的治理过程及故障产生的原因。
When the gas turbine starts at low speed,the circuit breaker(52ss)of LCI(ls2100e)isolation transformer is disconnected without any fault alarm.LCI will shut down the LCI after detecting that 52ss is disconnected,resulting in the failure of gas turbine startup.This paper introduces the treatment process and final cause analysis of LCI device's accidental trip at low speed.
