关于补偿电容损坏的原因分析及防护探讨

Analysis and discussion on reason and protection to failure of compensation capacitor

在UM71无绝缘轨道电路和ZPW-2000A移频自动闭塞中,为延长轨道电路传输距离,要求安装补偿电容,以保证发送和接收设备可靠工作。主要就补偿电容损坏的原因进行分析,提出防护措施。

The compensation capacitors was used to extend the transmission distance of the track circuit, ensure the sending and receiving devices work reliably in the UM71 non-track circuit territory and ZPW-2000A FSK auto-blocking. On this basis, it was studied the reason about the failure of compensation capacitor and put forward some method to improve it.
