高频通道阻波器在线检测方法初探

Study on High Frequency Channel Trapper On-line Detecting

分析宽带阻波器异常运行情况及其对高频保护的影响。对现行阻波器检测方法加以比较,指出了各种方法存在的不足。提出了利用检测CVT分压电容器上流过的高频电流分量值判断阻波器是否故障的新思路。

This paper analyzes the abnormal conditions of operating wide band trapper ,and its influence on HF Protection System. In the paper, the present detective methods of trappers are compared, and the shortcomings of every detective methods are pointed out. A new thinking to recongnize whether or not trappers are out of order is put forward. That is to measure the HF current component in voltage division capasitors of CVT.
