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。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:
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。
注:也可分离电子线路板后进行绝缘测试
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
Vertical Horizontal

8.1 欠压脱扣器
断路器带有欠压脱扣器时,应使欠电脱扣器先通电,断路器才允许合闸.
根据外挂欠电压模块上的接线端子编号接入电源(直流电源不必区分正负极)
当电源电压下降到欠压脱扣器额定工作电压的 70%~35%
范围内时,欠压脱扣器能可靠的分断断路器;当电源电压
低于欠压脱扣器额定工作电压的 35%时,欠压脱扣器能防
止断路器闭合;当电源电压高于欠压脱扣器额定工作电压
的 85%时,欠压脱扣器能保证断路器可靠闭合。
8.1Undervoltage tripper
When the breaker has an undervoltage tripper, the undervoltage tripper should be electrified,
and then the breaker allows switch on.
Power supply is accessed according to wiring connector number on
