摘要

对一起典型直流融冰装置误操作导致的过电压故障进行分析，指出交流电压从直流融冰装置输出反作用至装置本体是导致本次故障的直接原因，因避雷器保护作用，融冰装置本体仍可正常使用。针对故障原因，对现有的直流融冰装置设计提出了改进建议。

Abstract

This paper analyzes the a typical over-voltage fault caused by the misoperation of DC ice-melting device. It is pointed out that the direct cause of this failure is that the AC voltage output from the DC melting device reacts to the device itself and due to the protection of the surge arrester

the ice melting device can still be used normally. According to the cause of the fault

some suggestions are put forward to improve the design of the current DC melting device.
