Abstract
The utility model relates to a rigid power transmission device which comprises a chain cage, a chain wheel, a chain, a three-station switch dynamic contact and a casing. The chain cage is in a U shape, the chain is arranged on the chain cage. The chain wheel and the chain are arranged in matched mode, and when the chain wheel rotates, the chain moves along the chain cage. The three-station switch dynamic contact is arranged in the casing through a conductive spring, the lower end of the three-station switch dynamic contact is connected with one end of the chain wheel, the upper end of the three-station switch dynamic contact is connected with an isolation switch dynamic contact, and the isolation switch dynamic contact, the three-station switch dynamic contact and the chain connected with the lower end of the three-station switch dynamic contact are arranged on the same vertical line. The rigid power transmission device drives the chain to perform vertical linear motion through rotation of the chain wheel to control the isolation switch dynamic contact to move vertically so as to control opening/closing of a vacuum breaker, enables the vacuum breaker to be compact in structure, and is small in parts, low in cost, simple in structure and practical.
Description
Technical field
The utility model relates to a kind of parts of vacuum circuit-breaker, particularly a kind ofly controls the rigidity power transmission that the isolating switch moving contact moves up and down, and belongs to vacuum circuit-breaker component technology field.
Background technology
At present, after existing vacuum circuit-breaker closed a floodgate, moving contact and fixed contact were in contact with one another, and for keeping this contact condition, needed additional structural to make moving contact keep "on" position.The vacuum circuit-breaker of this structure uses inconvenient; And prior art complex structure, the realization of function need different operating mechanism and different drive mechanisms to realize.Amount of parts is many, and electric conductor is many and cause cost very big.The caloric value of equipment influences stability greatly.
The utility model content
The purpose of the utility model is to provide a kind of rigidity power transmission that the isolating switch moving contact moves up and down of controlling.
The utility model is realized through following technical scheme: a kind of rigidity power transmission comprises chain retainer, sprocket wheel, chain, three-station moving contact, housing; Said chain retainer is the U type; Said chain is arranged on the chain retainer; Said sprocket wheel and chain are equipped with, and when sprocket rotation, chain moves along the chain retainer; Said three-station moving contact is arranged in the housing through power spring; The lower end of said three-station moving contact links to each other with an end of sprocket wheel; The upper end of said three-station moving contact links to each other with the isolating switch moving contact; Said isolating switch moving contact, three-station moving contact, be arranged on the same vertical curve with the chain of the lower ends of three-station moving contact.
Preferably, the rotating shaft of said sprocket wheel is provided with the rotary handle of a control sprocket wheel rotation.
The beneficial effect of the utility model is embodied in: the described rigidity power transmission of the utility model; Rotation drive chain through sprocket wheel is done rectilinear motion up and down; Control moving up and down of isolating switch moving contact; So that control the cut-off/close of vacuum circuit-breaker, make vacuum circuit breaker constructions compacter, parts are few, cost is low; The utility model is simple in structure, practicality.
