IntroductionParametersAccessoriesService
        变压器 绕组的直流电阻测试是变压器在交接、大修和 改变分接开关后,必不可少的试验项目。通过测 量变压器绕组的直流电阻,可以检 查出引线的焊接或连接质量,绕组有 无匝间短路或开路,以及分 接开关的接触是否良好等情况。在以前 对直阻的测量均采用QJ44双臂电桥来测量,而这类 电桥的测量电流为毫安级,测量起 来时间需要很长,而且精度也较低。为了改变这种状况,缩短测 量时间以及减轻测试人员的工作负担,武汉国 电铭科电气有限公司开发了TKZZ-2A直流电阻测试仪。本产品是取代直流单、双臂电 桥的高精度换代产品。仪器采 用了先进的开关电源技术,其测量 速度比电桥快一百多倍,显示部分由四位半LCD液晶显示测量结果,三位半LCD液晶显 示环境温度或测试电流值,克服了 其它同类产品由LED显示值 在阳光下不便读数的缺点,同时具 备了自动消弧功能。本仪器具有测速快、精度高、显示直观、抗干扰能力强、体积小、耗电省、测试数据稳定可靠、不受人 为因素影响等优点。仪器内 可选装可充电电池组(14.8V),交直流两用,便于现场及野外测试。本产品符合DL/T 845.3-2004《电阻测 量装置通用技术条件 第3部分直流电阻测试仪》的要求。
