10kV电缆故障查找方法

Detection method for 10 kV power cable

电缆故障查找技术是电网安全运行的主要支持技术之一,电缆故障测试现场环境恶劣,杂音大,传统的精确定点法很难迅速找到故障点,应用二次脉冲法有利快速找到故障点。本文详细介绍了发生电缆故障的原因,并对传统的电缆故障检测方法进行了概述和分析。在此基础上,本文提出了一种新型的10 kV电缆故障查找方法——二次脉冲法。

The power cable fault detection technology is one of the main support technology in the safe operation. The traditional fixed-point method has difficulty to find the exact point of failure because adverse and noise test environment. However, second pulse method can quickly find the point of failure. This paper describes reason of power failure and analyzed traditional cable fault detection methods. On this basis, the paper proposes a novel method of 10KV cable fault to find the second pulse method.
