摘要
在现场使用过程中,锁闭检查器(包括VCC和VPM)表示部分存在绝缘电阻低的问题。通过更换接点材料和对原接点材料进行绝缘处理并结合12个周期交变湿热实验数据分析,提出2种提高道岔锁闭器接点系统绝缘性能的方案。
In the process of field application,poor insulation resistance exists in the indication part of switch locking devices,including VCC and VPM.Through replacing contact materials or conducting insulation processing of materials for the existing contacts,two solutions to improve the insulation of the system were proposed by analyzing the data from a 12 cycle alternating hot and humid experiment.
