分励脱扣器 的简介1 范围:
配DZ47分励脱扣器 MX+OF,主要适用于交流50HZ(或60HZ),额定电压至400V的线路中与DZ47小型断路器或多极断路器配装做远距离操作,指示断路器通断状态。
2 正常工作条件和安装条件:
周围空气温度为:-5℃~+40℃,24小时内其平均值不超过+35℃。
海拔高度:不超过2000M。
大气条件:安装地点的空气相对湿度在最高温度为+40℃时不超过50%;
在较低的温度下可允许有较高相对湿度,最湿月的月平均最低温度不超过+25℃,该月的月平均最大相对湿度不超过90%,并考虑到因温度变化发生在产品表面上的凝露。
污染等级:为污染等级2。
安装类别:为安装类别Ⅱ Ⅲ。
3 基本参数及技术性能:
基本参数
a:额定绝缘电压(UI):500V
b:额定控制电源电压(US):AC:230,400V.
主要性能指标 动作特性:
a: 在额定控制电源电压值的70%~110%,脱扣器均应可靠动作使断路器断开。
b:触头分断能力 AC:3A/400V;6A/230V;
c:寿命 脱扣器操作寿命不低于0.4万次。
4 主要工作原理:
脱扣器主要由手柄,脱扣机构,电磁系统,指示件,外壳等零件组成。当脱扣器未合闸时,常闭辅助触头接通,外接安全信号灯亮,当配装断路器合闸,并带动脱扣器合闸时,脱扣器常闭辅助触头断开,常开辅助触头接通,外接警告信号灯亮;当接按钮接通时,脱扣器电磁系统吸合,使脱扣机构动作,从而带动配装断路器脱扣分断达到分励脱扣目的,与此同时,脱扣器指示件动作显示脱扣标记,脱扣器常开触头分断,常闭接通,外接信号指示转换。
5 安装使用及维修:
安装使用安装前先检查脱扣器与所使用的正常工作条件是否相符。 维修 脱扣器在保修期限内,如发现问题可找分销商进行联系。
6 注意事项:
a:脱扣器的接线方式应正确
b:脱扣器在接线时需将接线螺钉拧紧。
c:安装使用安装前先检查脱扣器与所使用的正常工作条件是否相符。维修脱扣器在保修期限内,如发现问题可找分销商进行联系。
