高压断路器触头电寿命诊断技术

ELECTRICAL ENDURANCE DIAGNOSIS OF HIGH VOLTAGE CIRCUIT BREAKER CONTACTS

提出了对高压断路器触头电寿命进行诊断的一种新的思路和方法，采用触头累积磨损量作为判断电寿命依据，基于该方法开发的装置与传统的诊断方法相比，能更准确地反映高压断路器的电寿命。

A new approach to diagnose electrical endurance of high voltage circuit breaker contacts is put forward in this paper. In this approach the total electrical attrition value is used as the criterion of electrical endurance. Comparing with the traditional methods, the electrical endurance of circuit breaker contacts can be more really diagnosed by use of the device having been developed by this approach.
