摘要
故障的精确定位可大大提高电力系统的运行效率 .利用GPS同步时钟 ,可以实现故障的时差定位 .为此 ,分析了高压线路故障时差定位系统的定位原理及对传感器的要求 ,介绍了几种传感器 ,提出了一种安装方便、响应快速的电流传感器及采用电流传感器的定位系统 ,并在 3km长的同轴电缆 (模拟 4.5km线路 )上进行了模拟测距试验 ,测距误差很小 。
The paper analyzes the mechanism of travelling wave based on fault location on high voltage transmission lines and the requisition for the sensor, and discusses some types of sensors. A current transformer with rapid response time is proposed, which is easy to install. A fault locator by using such a current sensor is also described. In the end, a test is made on a 3km long coaxial cable for simulating a 4.5km high voltage transmission line. The result of the test shows that the locating error is not longer than 60m, which means the locating system is satisfied.
