Problems solved by technology

The spring operating mechanism is the most commonly used type of circuit breaker at present. Its closing and opening are both powered by springs. Generally, it includes an energy storage unit, closing transmission unit, opening and tripping unit, etc. The existing Due to the large number of parts and components of the spring operating mechanism, it is easy to cause the appearance and volume of the related product mechanism to be too large, the installation is complicated, the operation is not clear, problems are prone to occur during operation, and the reliability is poor. In addition, the existing operating mechanism has no Expansion space, poor protection function, inconvenient operation

Abstract

The invention relates to an indoor circuit breaker spring operating mechanism. The technical problem to be solved by the invention is to provide the indoor circuit breaker spring operating mechanism which is compact in structure and large in expansion space. According to the technical scheme, the mechanism comprises a mechanism left side plate, a mechanism right side plate, an installation supporting rod, a switching-off spring, a three-phase output crank arm assembly, an energy storage motor, a switching-on spring, a gear transmission assembly and a transmission shaft; the three-phase output crank arm assembly comprises an output movable rod, an upper output crank arm, a middle output crank arm and a lower output crank arm; the output movable rod is provided with a switching-off spring fixing hole, one end of the switching-off spring is fixed on the switching-off spring fixing hole, and the other end of the switching-off spring is fixed on an adjusting head. The mechanism has the advantages that the switching-on spring, the switching-off spring and the three-phase output crank arm are combined into a whole, and the modular mechanism is convenient to install, large in expansion space and convenient to operate.

Description

technical field [0001] The invention relates to a spring operating mechanism of an indoor circuit breaker. Background technique [0002] The operating mechanism of the indoor circuit breaker provides power output for the circuit breaker, and its function is to drive the moving conductive rod of the vacuum interrupter through the action of the operating mechanism to realize the opening and closing of the circuit breaker. The spring operating mechanism is the most commonly used type of circuit breaker at present. Its closing and opening are both powered by springs. Generally, it includes an energy storage unit, closing transmission unit, opening and tripping unit, etc. The existing Due to the large number of parts and components of the spring operating mechanism, it is easy to cause the appearance and volume of the related product mechanism to be too large, the installation is complicated, the operation is not clear, problems are prone to occur during operation, and the reliab...
