摘　　要：电缆中间接头局部放电是造成交联聚乙烯电力电缆绝缘破坏的主要原因。针对电缆中间接头局部放电敏感交联聚乙烯电缆中间接头局部放电释放的特殊气体,实现局部放电强度及其对绝缘材料的破坏程度的检测,实现电缆连接头局部放电特性的长期在线检测,保证电网运行安全。Partial discharge of cable intermediate joint is the main reason for the insulation damage of XLPE power cable.he paper deals with the partial discharge of the partial discharge of the cross-linked polyethylene cable in the intermediate joint of the cable intermediate joint to realize the partial discharge intensity and its The detection of the degree of damage of the insulating material enables long-term online detection of the partial discharge characteristics of the cable connector to ensure the safe operation of the power grid.

关 键 词：电缆中间接头 局部放电 放电强度 在线监测
