摘要
在电力系统中,六氟化硫(SF6)因其优异的绝缘性能被广泛用作绝缘气体.然而,SF6 在电弧、放电等高能状态下可能分解,生成多种分解产物.本研究通过分析SF6 分解产物来判断断路器的潜在故障,利用高精度的气相色谱-质谱联用仪(GC-MS)对分解产物进行检测,并结合实际断路器故障案例,探讨分解产物的特征与断路器故障类型之间的关系.本研究结果不仅提高了断路器故障诊断的准确性,也为SF6 的安全使用提供了科学依据.
Abstract
In the power system,sulfur hexafluoride(SF6)is widely used as an insulating gas due to its excellent insulation properties.However,SF6 can decompose under high-energy conditions such as arcs and discharges,generating various decomposition products.This study aims to diagnose potential faults in circuit breakers by analyzing the decomposition products of SF6.A high-precision gas chromatography-mass spectrometry(GC-MS)instrument is used to detect the decomposition products,and the relationship between the characteristics of the decomposition products and the types of circuit breaker faults is explored by combining practical circuit breaker fault cases.The results of this study not only improve the accuracy of circuit breaker fault diagnosis but also provide a scientific basis for the safe use of SF6.
