    DZ47(C45)高分断小型断路器,是上海人民电气有限公司 http://www.shamandq.com 为您提供的关于DZ47(C45)高分断小型断路器型号,DZ47(C45)高分断小型断路器价格...

产品介绍

主要用于交流50Hz/60Hz,额定电压至400V,电流至63A的电气线路及设备的过载和短路保护中,亦可用于作为线路不频繁转换之用。

小型断路器又分为C型和D型,一般家用为C型断路器电动机保护中选用D型断路器

按极数分类有:

单极(1P)断路器(微断、空气开关)

DZ47-63/1P?6A,DZ47-63/1P?10A,DZ47-63/1P?16A,DZ47-63/1P?25A,DZ47-63/1P?32A,DZ47-63/1P?40A,DZ47-63/1P?50A,DZ47-63/1P?63A.

二极(2P)断路器(微断、空气开关)

DZ47-63/2P?6A,DZ47-63/2P?10A,DZ47-63/2P?16A,DZ47-63/2P?25A,DZ47-63/2P?32A,DZ47-63/2P?40A,DZ47-63/2P?50A,DZ47-63/2P?63A.

三级(3P)断路器(微断、空气开关)

DZ47-63/3P?6A,DZ47-63/3P?10A,DZ47-63/3P?16A,DZ47-63/3P?25A,DZ47-63/3P?32A,DZ47-63/3P?40A,DZ47-63/3P?50A,DZ47-63/3P?63A.

四极(4P)断路器(微断、空气开关)

DZ47-63/4P?6A,DZ47-63/4P?10A,DZ47-63/4P?16A,DZ47-63/4P?25A,DZ47-63/4P?32A,DZ47-63/4P?40A,DZ47-63/4P?50A,DZ47-63/4P?63A.

按额定电流分:

6A、10A16A20A25A32A40A50A63A

额定工作电压单极为230V/400V,二极、三级、四级为400V.

按瞬时脱扣电流分C型和D型。

周围空气温度不低于-5度,不高于+40度,日平均值不超过+35度。

安装地点海拔高度不超过2000米。

大气相对湿度,在最高温度+40度时不超过50%,在较低温度时可以有较高湿度,如最湿月平均温度不超过+25度时,月平均相对温度不超过90%,并允许由于温度变化发送在产品表面的凝露。

断路器(微断、空气开关)使用地点的等级污染等级为2级。

断路器采用TH35-7.5型钢安装导轨安装。

断路器的安装类别通常为IIIII类。

断路器按正常工作位置安装,安装面与垂直面的斜度不大于正负5度。

断路器接线方法,用螺钉压紧接线。

断路器具有隔离功能。

 

本断路器(微断、空气开关)有触头、灭弧系统,电磁系统和脱扣机构及操作机构而组成,

电磁系统采用精密型和电阻型双金属材料,触头采用银氧化镉触头,另外还选用了增强耐弧塑料等新型材料,保证产品性能。

断路器的工作原理:

在断路器(空气开关)的正常工作情况下按动操作机构,使电源接通,此时脱扣机构闭锁,触头不动作,当电流过大时,电磁系统的双金属片产生变形,推动锁扣,使铁芯被吸引,触头在释放弹簧的作用下而断开,完成断路器的分断保护。

断路器安装前应注意以下事项:

检查断路器,确认完好无损,动作灵活;

检查断路器的标志是否与所使用的正常工作条件符合。

断路器安装时应注意接线端的标志。正确安装。

额定电流不能自行调节,且不需要进行维修。

安装及拆卸方法:

将断路器入轨处对准安装导轨下端,使断路器沿箭头方向向上推动,并按箭头放心将凹处推到安装导轨上端,松手即可。

与安装过程相反,使断路器沿箭头方向向上顶,使断路器反方向转动,即可卸下。

断路器(空气开关)(包括装箱产品)在运输和保管中,均不得受雨水侵袭,产品应放置在无雨雪侵入、空气流通的环境里,月平均相对湿度不大于90%(在20±5℃时),空气温度不高于+40℃与不低于-25℃的库房中。

断路器在运行中应定期检查,清除进出线及产品表面灰尘及污物,检查时应该却断电源,检查周期视工作条件绝对。
