发电厂继电保护改造拆接线工作控制措施

Control Measures for Dismantling and Wiring Work of Relay Protection Upgrading in Power Plant

继电保护改造工程如果没有正规的技术措施保障,会造成拆线工作中出现漏拆、错拆的情况,接线工作出现错误,会危及机组的安全稳定运行,甚至造成设备损坏。结合某发电厂的实际事故,分析机组非停和主变损坏的原因,并针对其中的不足提出有效的改进和控制措施。

If there is no specified technical guarantee measures for the relay protection renovation project, there will cause missed and wrong dismantling in wire dismantling work, and errors in wiring work, which may endanger the safe and stable operation of the power unit, and even cause equipment damage. Based on the actual accident case in a power plant, this paper analyzes the causes of unplanned shutdown of unit and transformer damage, and puts forward effective improvement and control measures towards those defects.
