DC75kV高压电缆头故障分析与对策

Analysis and Countermeasures of DC75kV High Voltage Cable Head Fault

为确定电收尘75kV交联聚乙烯绝缘直流高压电缆终端头闪烙事故的原因,通过对事故电缆终端头检查、分析,认为电缆终端头安装不符合要求是电缆终端头被击穿的主要原因,重点阐述了DC75kV高压电缆头制作工艺,提出了预防同类事故发生的相关对策。

In order to determine the cause of the flashover accident of 75kV cross-linked polyethylene insulated DC high-voltage cable terminal with electrostatic precipitator,through inspection and analysis of the accident cable terminal,it is considered that the main reason for the breakdown of the cable terminal is that the installation of the cable terminal does not meet the requirements.T he treatment process of DC 75kV high-voltage cable head is emphasized,and relevant countermeasures to prevent similar accidents are proposed.
