Technical field
The utility model belongs to breaker technical field, and in particular to a kind of reduction speed vacuum circuit breaker closing rebound and
The device of impact.
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.When separating brake, when the moving contact of vacuum bubbles moves to separating brake extreme position speed still compared with
Height, moving contact and locating part collide and generate rebound, and when the distance between moving contact and static contact are too small, generation is put
Electricity, i.e. generation arcing.It shoves and is endangered caused by arcing switching devices or even entire power grid very greatly.
It is to increase energy storage equipment for the measure that the closing rebound problem of above-mentioned moving contact is generally taken, to store dynamic touching
The energy of head collision reaction, prevents its closing rebound；Increase damping device is mostly used to the separating brake bounce problem of moving contact,
To store the energy of moving contact, rebound after preventing its separating brake, but due to the setting of energy storage equipment, increase moving contact movement
Moving resistance, and then increase the required combined floodgate primary power of driver driving.

The device of lock spring and impact, it reduces moving contact to the impact dynamics of static contact, largely reduces moving contact rebound
Possibility, energy needed for not increasing combined floodgate.
The technical solution adopted in the utility model is as follows:
A kind of device reducing speed vacuum circuit breaker closing rebound and impact, including cabinet and is installed on cabinet one end
Vacuum bubbles, are equipped with static contact and moving contact in the vacuum bubbles, and described moving contact one end is located in vacuum bubbles, other end connection
There is insulated pull rod, the insulated pull rod other end is connected with buffer gear, it is characterised in that: the buffer gear includes damping
Seat, the damping device are fixedly mounted on the other end of cabinet, and mounting groove, peace in the mounting groove are offered in the damping device
Equipped with connecting rod, described connecting rod one end is fixedly connected with insulated pull rod, the other end is connected with driver, in the mounting groove also
Damping piece is installed, for the damping piece between connecting rod and damping device, described damping piece one end is equipped with damping block, described
Damping block is slidably mounted in mounting groove, and damping flap is equipped on the damping device, and via hole, institute are offered on the damping block
State connecting rod to be slidably mounted in via hole, baffle be installed in the connecting rod, the baffle be located at damping block and driver it
Between.
Based on the above technical solution, the utility model has also done following improvement:
It further limits, connecting rod is multi-diameter shaft, and the baffle is slidably located in connecting rod, is installed in the connecting rod
There is locking member, the baffle is fixedly mounted in connecting rod by locking member.
It further limits, the card slot to match with baffle is offered on the damping block.
It further limits, the damping piece is spring.
It further limits, the connection boom end is equipped with threaded post, and the insulated pull rod end offers and threaded post phase
Matched threaded hole, the connecting rod are screwed onto threaded hole.
It further limits, breaker is in damping piece when gate-dividing state and is in compressive state.Damping piece has centainly
Initial pressure, preferably moving contact can be prevented to spring back after further compression.
The utility model has the beneficial effects that
When the compression direction and combined floodgate of damping piece moving contact the direction of motion on the contrary, close a floodgate when damping block, damping piece and
It under the action of baffle, is buffered by baffle impact damping block, to reduce moving contact to the impact dynamics of static contact；Damping
Part in the raw when, baffle is separated with damping block, do not increase combined floodgate needed for energy, do not influence close a floodgate starting the time；Simultaneously
It is closing a floodgate to when separating brake movement, baffle delay disconnects, and reduces separating brake rebound, does not influence opening velocity；When separating brake is to feed motion,
Baffle delay contact, reduces closing rebound.
