光纤外护套绝缘故障的监测

Insulating Fault Monitoring for the Submarine Communication Optical Cable

为了保障长途海底光缆的运行可靠性,需要尽早发现潜在的故障。本文介绍了一种监测海底通讯光缆外护套电绝缘性能的方法。该方法使用微控制器控制高压信号源,并同时精确控制测试电流。使用这种方法可以早期发现海底光缆的损伤。

In order to ensure the reliable operation of the long-distant undersea optical cable, it is necessary to detect the delitescent fault in earliest time. This paper introduces a method for monitoring insulation performance of the undersea communication optical cable. The micro-con- troller is used to control the high-voltage signal source and the measuring current. This method can be used in the early detection of undersea optical cable injury.
