Abstract
The invention discloses a rigid power transmission device which comprises a chain holding rack, a chain wheel, chains, a three-position switch movable contact and a housing, wherein the chain holding rack is U-shaped; the chains are arranged on the chain holding rack; the chain wheel and the chains are arranged in a matched manner; when the chain wheel rotates, the chains move along the chain holding rack; the three-position switch movable contact is arranged in the housing through conductive springs; the lower end of the three-position switch movable contact is connected with one end of the chain wheel; the upper end of the three-position switch movable contact is connected with an isolating switch movable contact; and the isolating switch movable contact, the three-position switch movable contact, and the chains connected with the lower end of the three-position switch movable contact are arranged on the same vertical line. According to the rigid power transmission device provided by the invention, the chains perform rectilinear motion up and down under the action of the rotation of the chain wheel so as to control the up-and-down motion of the isolating switch movable contact and control the switching-on and switching-off of a vacuum circuit breaker; and the vacuum circuit breaker has a more compact structure and less components, and is cost-saving. The rigid power transmission device provided by the invention has the advantages of simple structure and practicability.
Description
Technical field
The present invention relates to a kind of parts of vacuum circuit-breaker, particularly a kind ofly control the rigidity power transmission that the isolating switch moving contact moves up and down, belong 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.
Summary of the invention
