文件编号:NDT-03560 文件版本:11 8.3 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 8.3Undervoltage 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).
3)维护检查必须有专业技术人员负责。/ Maintenance checks should be done by specialized technical personnel. 4)用户如需选用内、外附件,按所订型号由本公司提供,以保证质量。如用户自行选购或改装,本公司不 能负责。/ User should use internal and external accessories provided by Nader so as to endure their quality; Nader should not be held reliable for purchase of accessories from other companies or authorized modifications.
文件编号:NDT-03560 文件版本:11 Remove the breaker from its installation position (normally for plug-in installation; it is recommended to do so for a fixing one). 断路器维护在正常操作条件下每年一次,在非正常条件下每半年一次,以下为维护内容: Maintenance of breaker is carried out yearly under normal use and every six months under abnormal use.
