Description
Technical field
The invention belongs to breaker technical fields, and in particular to a kind of breaker closing spring secondary buffer device.
Background technique
Higher new demand is constantly proposed to the performance of the divide-shut brake of high and low pressure mechanical switch at present, it is desirable that its division
The lock time is shorter, does not generate arcing.This necessarily makes the moving contact of the vacuum bubbles of the core component as high and low pressure mechanical switch
Moving contact does not generate spring when having higher speed in switching on and off, and closing a floodgate, not electric arc of discharge, does not generate after separating brake anti-
Bullet, arcing of not discharging.When combined floodgate, the moving contact of the high-speed motion of vacuum bubbles and its static contact are collided, close to elastic collision, this
When velocity reversal movement of moving contact when will be with before former collision, moving contact spring cause switch to close and separated when closing a floodgate, draw
Biggish electrical impact is played, generation is shoved, and is shoved and is endangered caused by arcing switching devices or even entire power grid very greatly.
Summary of the invention
The problem of mentioning in technology based on the above background, the present invention provides a kind of breaker closing spring level 2 buffering dresses
It sets, combined floodgate impact energy is effectively reduced in it, reduces closing rebound, while can preferably avoid generating surge.

A kind of breaker closing spring secondary buffer device, including static contact and moving contact, the static contact are equipped with true
Vacuole, described moving contact one end are located at the other end in vacuum bubbles and are connected with insulated pull rod, and the insulated pull rod other end is connected with
First-level buffer mechanism, the first-level buffer mechanism are connected with driver, and level 2 buffering mechanism, institute are equipped in the insulated pull rod
It states and the first damping piece is installed in first-level buffer mechanism, the second damping piece is installed in the level 2 buffering mechanism, described first
Elastic strength of the elastic strength of damping piece less than the second damping piece.
Based on the above technical solution, the present invention has also done following improvement:
It further limits, the first-level buffer mechanism includes guide rod and guide sleeve, and the guide rod sliding is arranged in guide sleeve, institute
It states guide sleeve lower end and first connecting rod is installed, the first connecting rod is fixedly connected with driver output shaft, first damping
Part is installed between guide rod and guide sleeve, and the second connecting rod is equipped on the guide rod, and the first connecting rod and insulated pull rod are solid
It is fixed to connect, the first stop collar is installed on the guide sleeve.When driver works, guide sleeve accelerates mobile the first resistance under effect of inertia
Damping member compression buffering, reduces combined floodgate impact energy, while pushing guide rod mobile.
It further limits, the guide sleeve inner wall is integrally formed with limiting stand.It, can be to the shifting of guide rod under the action of limiting stand
Dynamic stroke is limited.
It further limits, the first connecting rod end is equipped with threaded post, and the insulated pull rod end offers and screw thread
The threaded hole that column matches, the threaded post are screwed onto threaded hole.It is easy to connect between first connecting rod and insulated pull rod, from
And facilitate the installation and removal of first-level buffer mechanism.
It further limiting, the level 2 buffering mechanism includes first sliding groove, and the first sliding groove is opened in insulated pull rod,
The first sliding block is slidably fitted in the first sliding groove, second damping piece is installed between the first sliding block and first sliding groove,
First sliding block is fixedly connected with moving contact, and the insulated pull rod is equipped with the second stop collar in first sliding slot opening end.?
It when combined floodgate is hit, continue to move to insulated pull rod can by compressing the second damping piece, thus slow to second of progress of combined floodgate shock
Punching, further decreases combined floodgate impact energy.
It further limits, the static contact includes contact base and contact head, and the second sliding block, institute are equipped on the contact head
It states and offers second sliding slot on contact base, the second sliding block sliding is arranged in second sliding slot, second sliding block and second
Third damping piece is installed, the contact base outer wall is equipped with limited location snap ring, and the contact base is limited equipped with third between sliding slot
Ring, third stop collar one end is slidably socketed on contact base, the other end is fixedly connected with contact head.When closing a floodgate shock,
Contact head can be compressed, the synchronous rebound of contact head when moving contact is sprung back, to make to protect between moving contact and static contact
Contact is held, the generation of surge is preferably avoided.
It further limiting, when breaker is in gate-dividing state, first damping piece and the second damping piece are compressive state,
The third damping piece is in compressive state.First damping piece and the second damping piece are provided with certain initial pressure, thus
After one damping piece and the second damping piece further compress, preferably moving contact can be avoided to spring back.
It further limits, initial pressure of the initial pressure less than the second damping piece of first damping piece, second damping
The initial pressure of part is less than the initial pressure of third damping piece.
Beneficial effects of the present invention:
1, the design of first-level buffer mechanism and level 2 buffering mechanism is by buffering to divide combined floodgate impact process one twice
Two, combined floodgate impact energy is effectively reduced in decreasing rebound stroke；
2, the seperated design of static contact, when moving contact hits contact head in making process, contact head is in third damping piece
Compressed under the action of 14, originally moving contact hit rebound when, the contact head of static contact under the action of third damping piece 14 with
With rebound, can preferably avoid generating surge.
