Product Introduction

目前,电力系统中普遍采用常规的QJ44型双臂直流电桥测量接触电阻,而这类电桥的测试电流仅mA级,难以发现回路导体截面积减少的缺陷。在测量高压开关导电回路接触电阻时,由于受触头之间油膜和氧化层的影响,测量值偏大若干倍,无法真实的反映接触电阻值。为此,电力部标准DL/T845.4—2004《电阻测量装置通用技术条件:回路电阻测试仪》和新版检定规程JJG1052-2009《回路电阻测试仪、直阻仪检定规程》作出对测量(隔离)开关、断路器等接触电阻的测量电流不小于直流100A,电流维持时间不低于600S的规定,确保试验结果准确。

Performance characteristics

本仪器操作面板采用人体工学设计,符合操作习惯,采用高频开关电源和数字电路技术,适用于开关控制设备回路电阻的测量。测试电流采用国家标准推荐的直流100A。可在直流100A的情况下直接测得回路电阻,测试结果用大屏幕液晶TFT彩屏显示,并有数据存储、输出打印、时间设置等功能,有50A、100A档位供用户选择;自定义测试时间,设定时间600S,是十分稳定的接触电阻测试仪,性能超过大电流微欧计。符合电力、供电部门现场高压开关维修和高压开关厂回路电阻测试的要求。
