摘要

气体因其具有优越的绝缘和灭弧性能

被广泛用作电力设备内部的绝缘介质

其运行状态直接关系到电力设备的运行情况。为了及时准确的掌握充气电力设备的运行状态

需要定期对其开展SF

气体状态检测。文中分别介绍了一起SF

气体纯度检测、SF

气体湿度检测和SF

气体分解产物检测典型案例

分析了异常情况发生的原因

并通过反复排查或解体检查验证了检测方法的可行性和准确性

为电力设备运行状态的准确评价提供一定的参考。

Abstract

gas is used widely as the internal insulating medium for power equipment due to its superior insulation and arc extinguishing performance and its operating state is directly related to the operation state of power equipment. For mastering the operation state of the gas filling power equipment timely and accurately

it is necessary to perform regularly SF

gas state detection. In this paper

such typical detection case as SF

gas purity

humidity and decomposition product is introduced respectively and the cause of abnormal case is analyzed. The feasibility and accuracy of the detection method is verified by way of either repeated inspection or disassembly so to provide a definite reference for the acc

urate evaluation of operation state of power equipment.
