某电厂超速限制OPC动作时，安全油压力开关复位导致停机。调节阀漏汽，LVDT工作温度过高，线圈短路，油动机失控导致停机。本文提出了设计改进建议。%When the Over Speed Control (OPC) acts very often, the pressure switches of safety fuel will be released, which maybe lead to the turbine tripped. Some steam leak out from the governor valve flange face. The work temperature of LVDT is very high. The coils of LVDT are sometimes short out. The actuator isout of control inducing the turbine tripped. The improvement suggestions are proposed in this paper.
