柜式GIS电缆终端不拆装核相方法

Phase-checking Method of the Cable Connected to Cubicle Type Gas Insulated Switchgear (C-GIS) without Dismounting Cable Terminal

在接有柜式气体绝缘金属封闭开关设备(C-GIS)的电缆改接工程中,传统方法须拆除电缆终端才能进行核相,拆装成本高、风险大。在分析了C-GIS电缆终端构造、维护要求以及电缆改接工程中传统核相方法工作流程的基础上,介绍了一种不需要拆装电缆终端核相方法的原理、特点以及在实际工程中的成功应用。

In the engineering of changing cable connection to cubicle type gas insulated switchgear （C-GIS）, traditional phase-checking method of cable needs to dismount cable terminal, in this way both cost and risk are high. On the basis of analyzing structure of C-GIS cable terminal, maintenance requirements, and working procedure of traditional phase-checking of the cable connected to C-GIS, the article describes the principle and feature of phase-checking method without dismounting cable terminal, and introduces the successful application in practical engineering project.
