户外隔离开关发热分析及预防处理措施

The Analysis and Preventive Treatment Measures of Outdoor Disconnecting Switch Overheating

随着电网规模的不断扩大以及状态检修的深入推行,户外高压隔离开关应用数量越来越多,检修机会却越来越少。当今社会供电负荷日益增加,因输变电设备过热而引起的停电事故时有发生,且发生频率呈上升趋势。详细分析了户外高压隔离开关的发热原因,并针对发热安全隐患提出了完善化改造处理方法。

With constant expansion of power grid and in-depth implementation of condition-based maintenance, the number of outdoor high-voltage disconnecting switch applied is increasing while less maintaining work is done. Nowadays, power load is increasing, thus, power blockage caused by overheating usually occurs, and the trend tends to go upward. The article focuses on the causes of outdoor high-vohage disconnecting switch overheating and proposes corresponding treatment.
