CJ16/19切换电容器接触器
一、概述 General description | ||||||||||||||||||||||||||||||||||
CJ16/19型切换电容器接触器是本公司早期参照德国西门子公司制造的3TK44cahacitorcontactor(电容器接触器)改进设计制造的,它的结构紧凑,主电路与电阻切合电路寓于一体,主电路接线方便,是控制小容量电容器常用的接触器。 CJ16/19is developd by our company on the base of 3TK44 capacitor contactor of Siemenscompany Germany. It ’ s structure is compact, maincircuit composed with resistanc on-off switch. joint the main circuit is convenience, is nidely used as a contactor in controlling small electriccapacitor , the model meaning as right. | ||||||||||||||||||||||||||||||||||

四、特点 Features | ||||||||||||||||||||||||||||||||||
接触器的接触系统是由上下两层八个触头组成三极主电路,每极主电路中都有一个触头是提前接通的,切合电阻只有两路,因为电容器组是三角形连接,故当电阻切合电路接通时,没相电容电路中均有电阻接入。 接触器备有两个辅助触头,其功能有两常开或两常闭或一常开一常闭,由用户在订货时选定。接触器安装方便,可用两只M4螺钉固定也可使用35mm安装轨固定。 The contact system of contactor is three-phase main circuit, composed by eight pieces contactblock from upside and daminside. There is one contact block was switch on in advance in eachmain circuit, switch-over resistro only two, the cap acitor groupis jointed as triangle, so whenresistor switch over circuit was sitchon, every capacitor circuit will be connected with resistor. The contactor have two pieces of auxilliary contact block, the function is 2NO, or 2NC or 1NO+1NC, this is chosed by user. The mounting of this contactor is very convenience, you can use two pieces of M4 screw makeit stable, or can use 35 mmDin real mount it. Over all Dimenseon as following. | ||||||||||||||||||||||||||||||||||
