摘　　要：箱式变压器断路器是风力发电机组的重要组成设备,其可靠性关系到机组安全稳定运行。若风电机组在发生故障时断路器拒动,将烧损机组相关设备导致事故范围扩大。而当前行业中部分风电机组的箱式变压器断路器可靠性并不高,往往有拒动的情况发生,现对一种箱式变压器断路器常见的拒动原因进行分析。Box transformer circuit breakers are important components of wind turbines,and their reliability is related to the safe and stable operation of the units,If the circuit breaker fails to operate when a wind turbine fails,it will burn out the relevant equipment of the unit and expand the scope of the accident,However,the reliability of box transformer circuit breakers for some wind turbines in the current industry is not high,and there are often cases of refusal to operate,This article analyzes the common reasons for refusal to operate a box transformer circuit breaker.
