变电站不停电近距离观察装置的设计与应用

Design and Application of Close Observation Device of Charged Equipment in Substations

根据《国家电网公司电力安全工作规程》规定,随着电压等级的升高,所对应的安全距离也越来越大,“超高压”设备及“特高压”设备离地距离会非常高,给高空带电设备的故障排查工作带来了很大的困难.在实际的现场运维工作中,对高空带电设备的巡视一直都是运维人员工作中的盲点,导致对设备缺陷无法及时发现和准确定性。研制了一种可以近距离观察带电设备缺陷、提升故障定性准确率的装置,对高压不停电设备近距离观察可能危及人身和设备安全的问题给出了解决方法.

According to the Electrical Safety Working Regulations of State Grid Corporation,the higher the voltage level,the greater the corresponding safety distance.Therefore,the ground distance of the "ultra-high-voltage" equipment and the "extra-highvoltage"equipment is very high,which brings great difficulties to the troubleshooting of high-altitude charged equipment.In the actual operation and maintenance work at the site,the inspection of the high-altitude charged equipment by operation and maintenance staff has always been a blind spot in the work,resulting in failure to detect equipment defects timely and determine the nature of the defects accurately.Therefore,a device that can realize close observation of the defects of charged equipment and improve the qualitative accuracy of faults is developed,which provides a solution to the problem that close observation of highvoltage charged equipment may endanger human and equipment safety.
