Abstract

The invention relates to a breaker. The breaker comprises an insulation cabinet, a main shaft, an on-off connecting lever, a closing connecting lever, an operating mechanism, an opening connecting lever and an opening extension spring, wherein the main shaft is connected with the insulation cabinet through a penetrating mode, the on-off connecting lever, the closing lever and the opening lever are fixed on the main shaft in a penetrated mode, the on-off connecting lever is connected with a vacuum tube via a super-path spring, the opening connecting lever is connected with the insulation cabinet via the opening extension spring, and the operating mechanism is slidably supported in the insulation cabinet by a mechanism base plate such that, when inserted into the insulation cabinet, the operating mechanism engages the closing connecting lever to be in driving cooperation therewith, and when pulled out of the insulation cabinet, the operating mechanism disengages from the driving cooperation with the closing connecting lever; and the operating mechanism comprises a motor, an input shaft, a closing shaft, a closing cam and a closing connecting rod set, wherein the motor is installed on the mechanism base plate, the input shaft and the closing shaft pass through vertical plates at both sides of the mechanism base plate, the motor drives the input shaft, the input shaft drives the closing shaft via a sprocket wheel set, and the closing shaft drives the closing shaft connecting rod set via the closing cam so as to drive the closing connecting lever to rotate the main shaft to enter a closing state.

Description

[0001] This application is a divisional application with the patent title: "A Modular Circuit Breaker". The application date of the original application is 2014-7-17, and the application number is 201410339587.9. technical field [0002] The invention relates to a circuit breaker, in particular to a modular assembly and disassembly circuit breaker. Background technique [0003] At present, in the high-voltage circuit breakers widely used in coal mine power systems, their functional components, such as operating mechanisms, motors, and releases, are installed in the narrow space of the circuit breaker box. With the gradual miniaturization of equipment requirements, , It is very inconvenient to install and maintain. Contents of the invention [0004] Aiming at the fact that the circuit breaker in the prior art cannot meet the miniaturization and convenient installation and maintenance requirements, the present invention provides a modular circuit breaker with simple and comp...
