变电站SF6断路器气体泄漏的常见原因分析及检测措施研究

因为SF6气体具备良好的绝缘性与灭弧作用,SF6断路器于高压设备方面占据绝对优势,所以其故障产生的频率也很高,最常见的问题是泄漏故障。迅速找到泄露点是处理泄漏故障的重要环节,对此,文章首先介绍了SF6断路器气体外泄的主要原因,然后详细阐述了有效的检测方法。

Because SF6 gas has good insulation and arc extinguishing effect,SF6 circuit breaker occupies an absolute advantage in high-voltage equipment,so its fault frequency is also very high,the most common problem is leakage fault.Finding the leakage point quickly is an important link to deal with the leakage fault.For this,the paper first introduces the main causes of gas leakage of SF6 circuit breaker,and then describes the effective detection methods in detail.
