摘要: 华电国际邹县发电厂335MW汽轮机高压遮断装置在做定期活动试验时,存在压力传感器故障、电磁阀卡塞、人为失误等因素造成的停机事故隐患。将高压遮断电磁阀组重新设计并加装隔离装置,活动试验时将在线安全油系统完全隔离,避免因硬件故障或操作不当而带来停机风险。

Abstract: In the periodical flexibility test of highpressure intercept device of 335MW steam turbine in Huadian International Zouxian Power Plant, some potential hazards of shutdown accident occurred, which include the fault of pressure transducer, the jam of electromagnetic valve, the human error and others. The highpressure intercept electromagnetic valve was redesigned, and an isolating device was added. In the flexibility test, the online safe oil system is completely isolated. Then the shutdown risk caused by hardware fault or improper operation can be avoided. 

Key words: high-pressure intercept device, isolating device, flexibility test, risk of shut-down
