Abstract

The invention relates to a vacuum circuit breaker, comprising a drive device (20), a transmission device (10), a main shaft (30), and a coupling (40), wherein the drive device has a rotatable drive shaft (22), the transmission device has a fastening frame (12) and a main-shaft connecting arm (18), which is arranged on the fastening frame, the axis line of the main shaft extends parallel to the side wall (52) of the vacuum circuit breaker, the main shaft passes through the fastening frame and is rigidly connected to the main-shaft connecting arm, and the actuation of the main shaft is transmitted to the transmission device by the main-shaft connecting arm. One end of the coupling is connected to the main shaft and the other end is connected to the drive shaft, such that the main shaft rotates together with the drive shaft. For the vacuum circuit breaker of said invention, a modular design is used, the assembly is uncomplicated, and the installation and the maintenance are simple.

Description

technical field [0001] The invention relates to a vacuum circuit breaker, in particular to a modular vacuum circuit breaker. Background technique [0002] A vacuum circuit breaker generally includes a frame, a drive device, a conduction device, a main shaft, an auxiliary switch, a pole, and the like. Such as figure 1 Shown is a conventional vacuum circuit breaker in which a frame 70 has two side plates 72 ( figure 1 Only one side plate is marked in ), and the main shaft 80 of the vacuum circuit breaker is arranged perpendicular to the side plate 72 of the frame. However, the vacuum circuit breaker arranged in this way has complex connection structures among various devices inside, high cost, difficult assembly and maintenance, and takes up a large space. Contents of the invention [0003] The object of the present invention is to provide a vacuum circuit breaker, which adopts modular design, has a simple structure, and is easy to assemble and maintain. [0004] The inv...
