摘要：When the 150MW steam turbine generator set of a power plant operates normally, the pressure of EH oil system gradually decreases and the fuel level drops in the tank, then switching to standby EH oil pump, the pressure of EH oil system continues to drop to the protection action, and the unit shutdown. Through on-site inspection and inspection of maintenance records, it was found that there was serious oil leakage at the oil outlet of mobile oil filter and the oil outlet pipe of EH oil cooling pump. The cause of the fault was analyzed accurately. Effective measures such as changing the connection mode between mobile oil filter and EH oilto eliminate the potential safety hazards in equipment operation.
