一种新型的塑壳断路器连接装置

本文介绍了几种目前主流的塑壳断路器接线方式,并对这些接线方式进行了简要的分析。对比这几种接线方式文中提出了一种新型的连接装置——母线式转接器,其采用的是凸轮滑块机构[1],可实现一次操作就完成进线端接线和断路器的安装固定。本文着重分析了该结构的设计要点,并在此提出部分改进方案。

This paper raises several main current connective ways of Moulded Case Circuit Breaker （MCCB）, and analyzes these connections. Comparing with these connection mode this paper provides a new connective way-Busbar Adapter Model, consisted of cam and slide. It can complete circuit connection and fixation of MCCB for once operation. This paper focuses on the analysis of the key points in the design of the adapter model, and then provide some improvement mechanism.
