一种断路器及其框架
摘要：
本发明提供了一种断路器及其框架，以解决现有技术中操作机构防护框架装配过程较繁琐的问题。断路器用框架包括用于安装操作机构、传动主轴和固封极柱的底座和与底座分体设置的操作机构防护框架，底座内具有用于安装传动主轴的安装空间，操作机构防护框架包括设于底座上的背板和两个侧板，所述背板和两个侧板上设有用于与底座形成用于容纳操作机构的容纳空间的顶板，所述背板、两个侧板和顶板由一块基板一体折弯而成。机构防护框架和底座分体设置，操作机构防护框架可以独立成型，可以将背板、两个侧板和顶板一体折弯成型，不需要考虑顶板、背板和侧板组装时的配合要求，减少了焊接和螺纹连接的数量，降低了操作机构防护框架装配时的繁琐程度。
摘要（英）：

The invention provides a circuit breaker and a frame thereof to solve the problem of the cumbersome assembly process of an operating mechanism protection frame in the prior art. The frame for the circuit breaker includes a base for mounting an operating mechanism, a driving spindle and a solid-sealed pole and an operating mechanism protection frame arranged separately from the base. The base has amounting space for mounting the driving spindle, the operating mechanism protection frame includes a back plate on the base and two side plates, a top plate for forming an accommodation space for accommodating the operating mechanism with the base is arranged on the back plate and the two side plates, and the back plate, the two side plates and the top plate are formed by integrally bending one substrate. The mechanism protection frame and the base are separately arranged, the operating mechanism protection frame can be independently formed, the back plate, the two side plates and the top plate can be integrally formed and bent, the cooperation requirements of the top plate, the back plate and the side plates in assembly are not considered, the number of welds and threaded connections isreduced, and the cumbersomeness of the operating mechanism protection frame in the assembly is reduced.
