绝缘测试 Insulation test
本断路器出厂前已按标准规定绝缘测试。因断路器带有电子线路板，安装前如进行复测，必须按如下
步骤：
Insulation test has been already carried out on the breaker according to standard before leaving
factory. Due to wire circuit, the following steps should be operated if insulation test is carried out on
the breaker again.
① 用 500VDC 兆欧表。500VDC tramegger.
② 在断路器处于断开状态，对进出连接板 1-2、3-4、5-6 之间，和 1、3、5 连接板与外壳之间（外壳用
金属箔覆盖）分别进行。When breaker is broken up, insulation test is conducted separately between
connecting panels 1-2, 3-4,5-6, connecting panels 1, 3, 5 and shell.
③ 对接至主电路的欠电压脱扣器，在进线与断路器外壳间。Undervoltage tripper connected to the main
circuit is arranged between intake wire and breaker shell.
④ 绝缘电阻不小于 20MΩ。Insulation resistance is not less than 20MΩ.
注:也可分离电子线路板后进行绝缘测试。
Notes: Insulation test could be operated after wire circuit is separated.
