Abstract

In this paper

the method of calculating the ablation coefficient K of the generator circuit breaker and measuring the dynamic resistance is presented. Without dismantling the arc extinguishing chamber of the generator circuit breaker of the pumped storage unit

the scientific residual electrical life evaluation of the generator circuit breaker for long-term operation is made and analyzed. The influence of different load interrupting current on the electrical life of circuit breaker is studied. The electrical life of the generator circuit breaker of Heimifeng Pumped Power Station is effectively improved through test optimization.
