摘要

针对在断路器不解体的状态下触头精确评估方法的不足

提出了一种基于辐射电磁波信号和动态电阻相结合的状态评估方法

并开展了真型试验验证。研究表明:当断路器触头存在劣化时

辐射电磁波信号和动态电阻均能间接反映触头信息

现场可采用这两种定性的方法相互印证

提高判断的准确度。

Abstract

This paper aims at the shortcomings of the accurate evaluation method of the contact of the circuit breaker under the condition of not disassembling

it presents a state evaluation method based on the combination of radiated electromagnetic signal and dynamic resistance measurement. And carried out the true type test verification

research shows: When the circuit breaker contact is deteriorated

the radiated electromagnetic wave signal and dynamic resistance measurement can indirectly reflect the contact information

these two qualitative methods can be used to verify each other and improve the accuracy of judgment.
