Description
Technical field
This utility model relates to vacuum switch, particularly to a kind of vacuum switch with contact buffer gear.
Background technology
Vacuum switch because of after its arc-extinguishing medium and arc extinguishing the dielectric of contact gap be all fine vacuum and gain the name；It has volume little,
Lightweight, be applicable to that frequent operation, arc extinguishing ability be strong, the advantage of contact life-span length, apply the most universal in power distribution network.Very
Empty switch moving contact when closing collides static contact with certain speed, owing to this collision is elastic collision, so from the beginning of contact
Touch steady closure can once or for several times bounce, and on the one hand this spring can produce arcing repeatedly, reduce the contact life-span very
To causing contact melting welding, on the other hand current oscillation can be caused in circuit.
The vacuum switch of prior art, its vacuum interrupter is all rigidly connected with the connection of Insulating frame, touches therefore, it is difficult to eliminate
Spring in head closing course.
CKJ5 the most current is serial, CKG4 collection of contact device, and ZN1, ZNY1 series vacuum circuit breaker etc., it is true
Empty arc-chutes are all rigidly mounted on Insulating frame.
The most such as Patent No. 201220719584.4 discloses a kind of high-pressure vacuum switch: includes housing, be arranged in housing
Vacuum interruption mechanism and operating mechanism；Described vacuum interruption mechanism includes that three horizontally disposed vacuum interrupters go out with each vacuum
The dynamic pull bar that in arc chamber, moving contact is connected；Described operating mechanism includes main shaft, three transmission components and has the magneto of drive rod
Drive mechanism；Described main shaft drives a corresponding dynamic pull bar to move back and forth by each transmission component, carries out divide-shut brake action；Described
Main shaft is provided with driving connecting lever, and described drive rod drives this driving connecting lever reciprocating rotation by a lever assembly；Described each transmission group
Part includes the divide-shut brake connecting lever being arranged on main shaft, the buffer pull rod that is rotationally connected with divide-shut brake connecting lever, is connected with buffer pull rod
Divide-shut brake lever, divide-shut brake lever is connected with dynamic pull bar again.This utility model structure more compact and reasonable, built-in by using
Permanent magnet type drive mechanism replaces traditional spring operation formula drive mechanism, effectively reduces overall volume, and improves stably may be used of work
By property.Although this utility model compact conformation, but simply solve the problem of drive mechanism, its vacuum interrupter and Insulating frame
Between connection be also rigidity, in the way of buffering, not do not solve the spring problem of contact closure.
Utility model content
The purpose of this utility model is to solve current contacts of vacuum switch Guan Bi to produce spring and produce arcing repeatedly and reduce the contact longevity
The shortcoming of life, proposes a kind of vacuum switch with contact buffer gear.
To achieve these goals, the technical solution of the utility model is as follows: a kind of vacuum switch with contact buffer gear,
It is characterized in that: include on framework, buffer element, vacuum interrupter, moving conductive rod, drive mechanism and vacuum interrupter
Moving contact and static contact, described moving contact is arranged on one end of moving conductive rod, and described moving conductive rod is connected with drive mechanism, described
Drive mechanism drives described moving conductive rod to move back and forth Guan Bi or the disconnection realizing vacuum switch, described vacuum interrupter, cushioning element
Being sequentially connected between part and framework three, during described vacuum interrupter Guan Bi, described vacuum interrupter can be due to described buffer element
Deformation and be subjected to displacement.
