Loop Resistance Tester
Loop Resistance Tester根据电力设备预防性试验规程《 DL/T 596 — 1996 》的要求,各种开关设备的导电回路电阻测试,其测试电流不得小于100A。由于接触面氧化、接触紧固不良等原因导致接触电阻增大,在大电流流过时,接触点温度升高,这更加速接触面氧化,使接触电阻进一步增大,持续下去将产生严重事故,因此有必要经常或定期对接触电阻进行测量。
回路电阻测试仪又称接触电阻测试仪,英文名称:Loop Resistance Tester。详细介绍按新《电力交配和预防性试验规程》要求,各种开关设备导电回路电阻的测量,其测试电流不得小于100A。
