电阻箱的故障分析与调修

Trouble Analysis and Repair for Resistance Box

电阻箱是广泛用于工矿企业、科研单位的重要精密电测量计量器具。本文对电阻箱的残余电阻大及接触电阻变差大、电阻箱示值超差、电阻箱回路不通或某几个电阻线圈不通三个方面常见的电阻箱故障进行了分析，并提出了调修和正确使用方法。

The resistance box is one of the most important instruments used in industry corporations and research units for electricity measurement. Through analyzing three common aspects of trouble, namely, abnormal of remaining resistance, value error and break of one or several loops, proposed ways of repair and methods of correct use of the resistance box.
