摘要
电缆中间接头因其复杂的绝缘结构,现场制作安装受工艺水平、环境条件、运行环境影响等已成为电缆运行的薄弱环节,特别是沿海地区高水位的运行环境,成为电缆中间接头故障的一个诱因。针对天津地区一起电缆中间接头事故,首先给出了电缆、电缆中间接头及保护动作情况,然后对电缆中间接头进行了解体分析,并分析了故障原因,最后给出了避免此类故障发生的具体措施。
Because of the complex insulation structure of cable connector,the influence of installation technology,installation environment,operating environment on cable connector field installation has become the weak point of cable operation.Particularly,the operation environment of high water level coastal areas may lead to cable connector fault.A case about cable connector fault in Tianjin is introduced.Firstly the cable,connector and protective action are described,then the dissection analysis of the connector is made,failure causes are analyzed.At last the measures against such failures are suggested.
