摘　　要：以一起风力发电用箱变低压断路器触头烧损为实例,对断路器进行温升试验和直流电阻测量,结果表明,触头烧损的主要原因在于断路器触头接触电阻大,并提出了相应的预防措施。Through a practical case of low voltage breaker contact burnout of box-type substation for wind power generation,the temperature rise tests and DC resistance measurement are performed on circuit breakers.The results show that the main cause for the contact burnout is the large contact resistance of the circuit breaker contact.Corresponding preventive measures are presented.
