变压器非电量保护误动问题分析与对策

Analysis and countermeasures of non-electricity protection mal-operation for transformers

变压器非电量保护的误动问题,一直是人们非常关注的问题。结合山东邹县电厂非电量保护误动问题及所采取的抗干扰措施,分析产生误动的原因,并通过理论分析及现场运行,证明所采取措施的正确性,为解决同类问题提供经验。

The mal-operation of non-electricity protection for the transformers is the problem that people pay close attention to very much.This paper analyzes the reasons for the mal-operation combined with the problem of non-electricity protection mal-operation in the Shandong Zouxian Power Plant and its countermeasures.The theoretical analysis and operating on site show that the countermeasures are correct and the experience is good for solving the similar problem.
