文件编号:NDT2920016 文件版本:4 7. 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.
文件编号:NDT2920016 文件版本:4 8. 附件说明书/ Accessory 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 35%~70% 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 欠压脱扣器接线图 的 85%时,欠压脱扣器能保证断路器可靠闭合。 Wiring diagram of under-voltage release 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 the external undervoltage module (anode and cathode of DC power supply are not differentiated).
