抽水蓄能机组出口断路器电气寿命评估方法研究

Research of Electrical Life Evaluation Method of the Breaking Current of the Generator Circuit Breakers

抽水蓄能机组出口断路器具有控制和保护机组的作用,抽水蓄能机组出口断路器电气寿命决定其正常运行周期。本文以断路器的开断电流为研究对象,分析了基于寿命曲线的相对电寿命法。结合某抽水蓄能电站机组优化停机前后断路器开断电流值的研究,对断路器电气寿命进行评估。

The breaking current of the generator circuit breakers play a role of controlling and protect!ng the unit,the normal operation cycle of generator circuit breakers are determined on their electrical life.Taking breakers1 breaking current as the research object,this paper analyzes the relative electrical life method based on Nk-Iki life curve.We also evaluating the electrical life of generator circuit breakers base on the study on it's breaking circuit before and after the optimal shutdown of the pushihe pumped storage power stati on.
