输电线路直流融冰线电缆拖放支撑架

Drag and Drop Bracket for DC Ice Melting Line of Transmission Line

2018年10月,红河供电局生产设备部、变电管理所、输电管理所开展110 kV线路移动式直流融冰应急工作方案的联合演练。在演练中发现存在“交直流电缆铺设水平距离”、“电缆拖放致绝缘层损坏”的问题。云南电网公司红河供电局输电线路八班根据工作实际需要出发,通过多次商议,研制了直流融冰交直流电缆所用电缆支撑架。

In October 2018,the production equipment department,substation management office and transmission management office of Honghe Power Supply Bureau carried out a joint drill on the emergency work plan for mobile DC ice melting of 110 kV lines.During the drill,the problems of“horizontal distance between AC and DC cables laying”and“insulation damage caused by cable drag and drop”were found.According to the actual needs of work,the eighth shift of transmission line of Honghe Power Supply Bureau of Yunnan power grid company developed the cable support frame for DC ice melting AC/DC cable through many discussions.
