Embodiment Construction

[0020] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0021] The specific embodiment of the spring operating mechanism provided by the present invention, such as Figure 1 to Figure 5 As shown, the spring operating mechanism in this embodiment includes a mechanism frame 300, and the mechanism frame includes a base, two side support plates, a top plate and side plates, and the mechanism frame also includes corresponding brackets that are correspondingly arranged on the base. The upper rotation is equipped with an output spindle 20 extending in the left-right direction. The base of the mechanism frame 300 is also fixed with a first mounting frame 100 and a second mounting frame 200 arranged at intervals in the left-right direction. The first mounting frame 100 includes Two first side plates arranged at intervals and a first support rod connected between the two first side plates, the two first side plates are...

Abstract

The invention relates to a spring operating mechanism, and the operating mechanism comprises a mechanism frame. The mechanism frame is rotatingly provided with an output main shaft which extends laterally. The mechanism frame is fixedly provided with a first installation frame and a second installation frame, which are arranged laterally at an interval. The first installation frame is provided with an energy storage unit which is used for storing energy and therefor providing a switching-on driving force for the output main shaft, and a switching-on tripping unit for controlling the switching-on operation. The second installation frame is provided with a switching-off tripping unit for controlling the switching-off operation. Compared with the prior art where an energy storage unit, a switching-on tripping unit and a switching-off tripping unit are disposed on the same installation frame, the installation mode of the mechanism can effectively simplify the overall structure of the first installation frame, can reduce the requirements for the installation frame effectively, and also facilitates the installation and maintenance.

Description

technical field [0001] The invention relates to a spring operating mechanism. Background technique [0002] In order to realize the production, transmission and distribution of electric energy, in addition to generators, transformers and transmission lines, various forms of switching devices are required to close and break circuits. It is also a switching device that can break a short-circuit current of up to hundreds of kiloamperes, that is, a circuit breaker. In order to achieve breaking and closing, the circuit breaker usually has the following three components: (1) breaking part, including conductive and contact system and arc extinguishing chamber; (2) operating and transmission part (3) insulating part . Among them, the operating mechanism provides the opening and closing driving force to the breaking part to meet the normal opening and closing operation of the circuit breaker. [0003] At present, the operating mechanism is divided into manual spring operating mech...
