安装方式/ Mounting Method
7.1 绝缘测试
本断路器出厂前已按标准规定绝缘测试。安装前如进行复测,必须按如下步骤:
① 用 500VDC 兆欧表
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。
③ 对接至主电路的欠电压脱扣器,在进线与断路器外壳间。
④ 绝缘电阻不小于 20MΩ。
7.2 安装
请安装在金属阻燃物上,断路器可垂直安装,也可以水平安装。
7..1 Insulation test
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
500VDC tramegger
② 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 Undervoltage tripper connected to the main circuit is arranged between intake wire and breaker
shell.
④ Insulation resistance is not less than 20MΩ.
Notes: Insulation test could be operated after wire circuit is separated.
7.2 Install
Installed on metal or other flameproof material in vertical or horizontal mode.
垂直安装 水平安装
