摘要
SF_6气体绝缘开关站广泛运用于电力系统中,在设备安装及运行过程中,须采用直流压降法进行主回路电阻的测量,检查开关、刀闸、导体等连接情况。本文就如何尽可能分段测量GIS回路电阻,以及如何开展长竖井出线段GIS回路电阻的测试,提出利用其他相母线作为测量回路的方法,保证测试结果准确的前提下,方便现场实施,对同类型GIS的回路电阻测试具有较强的参考意义。
The SF6 gas insulated switchgear is widely used in the power system, during the installation and operation of the equipment, the DC voltage drop method should be used to measure the main circuit resistance and check the connection of circuit-breaker, disconnecting-switch and conductor. In this paper, with respeet to how to measure the GIS segment loop resistance as much as possible, and how to carry out the test of the GIS loop resistance of the long shaft outlet line, the method is put forward to use other phase bus as the measuring circuit, the on-site implementation is convenient under ensuring the premise of the aceurate test results, and it has a strong reference value for loop resistance testing of the same type of GIS.
