摘要
对某火电厂前置泵油站异常跳闸事故进行分析。通过分析,发现该事故的直接原因为前置泵油站远方控制回路失电,根本原因为前置泵油站厂用电供电回路设计不合理。针对发现的问题,从现场安全防护及厂用电供电电源改造方面提出整改措施,杜绝类似问题再次发生。
The abnormal trip accident of booster pump oil station in a certain thermal power plant is analyzed. By analysis,it is found that the direct reason of the accident is because of the lost power of remote control circuit in booster pump oil station and the fundamental reason is the unreasonable design of power supply circuit of auxiliary power of in booster pump oil station. Aiming at problems found,correction measures are proposed from aspects of field security protection and modification of power supply source of auxiliary power to prevent similar problems from happening again.
