    发布日期:2020-06-20 点击:3401次

    产品别称


    智能回路电阻测试仪、智能接触电阻测试仪、接触电阻测试仪、开关回路电阻测

    试仪、接触回路电阻测试仪

     

          产品简介

    智能回路接触电阻测试仪是用于测量开关、断路器、变压器等设备的接触电阻、


    回路电阻的专用测试设备。其采用典型的四线制测量法,通过输出一个直流电流


    ,施加于被测体的两个端钮之间,并测量电流流过被测体所产生的压降,然后通


    过电压和电流之比得出被测体的直流电阻。主要由恒流源、前置放大器、A/D转换


    器、指示装置等部分组成。

    Loop resistance tester is the special test equipment for measuring the


    contact resistance and loop resistance of some devices such as switch,


    circuit interrupter, and transformer and so on. It adopts the typical


    four-wire method of measurement which helps get the DC resistance


    through the following steps: outputting a DC current, applying the


    current to the tested body by linking its two terminals, and measuring


    the voltage drop when the current goes through the tested body, then


    dividing the current by the voltage. In addition, it mainly consists of


    constant current source, preamplifier, A/D converter, indicating device


    and so on.
