摘要/Abstract

摘要： 随着2008年东风发电厂GIS大修改造的进行及即将进行的发电机变压器组保护装置换型改造，在实现主设备保护装置双重化配置的基础上，同步进行断路器操作回路的双重化配置以及相关回路的应用显得尤为重要。针对目前东风发电厂220kV断路器操作回路存在的问题，如直流操作电源、防跳等相关回路进行了研究，对220kV断路器操作回路的改造方案进行了探讨，提出了具体建议。

Abstract: As the GIS overhaul progressed and the upcoming retrofit of protection device for generatortransformer unit in Dongfeng Power Plant, it is more important to synchronously implement the duple configuration of breaker operating circuit and the application of related circuits at the foundation of achieving duple configuration of main equipments. The main problems existing in 220kV breaker operating circuit of Dongfeng Power Plant, such as DC operating power supply, tripping prevention, etc., were researched, the retrofit scheme of 220kV breaker operating circuit has been investigated, and the substantial suggestions were proposed in this paper.
