Abstract

The invention provides a novel tension spring type circuit breaker operation mechanism. The novel tension spring type circuit breaker operation mechanism comprises a rack, a fixed shaft, a tension spring, a connecting rod, a lever and an operation shaft, wherein one end of the connecting rod is fixedly connected with the lever and the other end of the connecting rod is hinged onto the operation shaft; the operation shaft is provided with at least one stirring sheet which drives the lever to rotate around the axis of the operation shaft in a rotating process; the fixed shaft is vertically fixed on a base plate of the rack; one end of the tension spring is fixedly connected with the fixed shaft and the other end of the tension spring is hinged to the lever; a column-shaped operation lug boss is further connected with an end part of the operation shaft; and the cross section of the operation lug boss is polygonal or arc-shaped. By adopting the novel tension spring type circuit breaker operation mechanism, an original operation connector tooth-shaped structure is changed, and the matching of the operation lug boss and an operation handle is utilized; and the process difficulty and the production cost are reduced and the reliability of a product is enhanced.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a novel extension spring type circuit breaker operating mechanism. Background technique [0002] When the operating mechanism of the medium voltage ring main unit of the universal circuit breaker controls the closing and opening of the electric load switch, it releases the energy by operating the handle to compress or stretch the spring, but the original tooth-shaped interface requires special equipment for processing, which is difficult to process And the manufacturing process is complicated, the cost is high, and the product reliability is not easy to guarantee. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to solve the problems in the prior art that the interface on the operating shaft of the circuit breaker operating mechanism requires special equipment processing, complex process, high cost, and difficu...
