Description
Technical field
The present invention relates to breaker technical field, specifically a kind of pole-mounted circuit breaker.
Background technique
In breaker open operation operating process, vacuum interrupter moving contact speed is very high, but movement travel and little.Make
It is stopped in shorter stroke, it is necessary to increase buffer unit to absorb the kinetic energy of motion parts, to prevent vacuum extinction
Rebound amplitude of the room in drop-out current after moving contact shock is excessive, causes to restrike, leads to failure of interruption and then accident is caused to be sent out
It is raw.
ZW32-12 type outdoor high-voltage alternating-current vacuum breaker, is all made of the mode of rubber buffer to carry out splitting lock cushioning,
Rubber buffer is reported to the leadship after accomplishing a task with rubber backing plate and metal caul and is formed by stacking.When breaker open operation, major axis horizontal hits metal gasket
Plate, impact force pass to rubber backing plate and next metal caul by metal caul.Rubber has certain elasticity, plays buffering and makees
With.Rubber backing plate is along the axial compression, and along the axial reversed expansion outward of surrounding, makes to produce between rubber backing plate and metal caul
Raw friction.A part of kinetic energy of motion parts just consumes in compression rubber, overcomes frictional force inside rubber and overcome rubber
In frictional force between metal caul, rebound effect can be reduced to a certain extent in this way.
This splitting lock cushioning mode following points disadvantage: 1, the kinetic energy usually only 30%~50% on buffer is acted on
Even smaller energy consumption is converted to thermal energy, effect is not apparent in friction；2, it is rushed due to valve rubber by strong
It hits, and elasticity is deteriorated at low ambient temperatures, is easy cracking failure etc., so big discounting of buffering effect by prolonged use
Button or even some mechanical property parameters of breaker may cause variation all to influence the performance of its performance.
It is found by retrieval, open circuit on a kind of column is disclosed in the Chinese patent that Authorization Notice No. is CN205194613U
Device brake separating buffer device and pole-mounted circuit breaker.The pole-mounted circuit breaker brake separating buffer device, including oil bumper, it is described
Oil bumper be fixed on bracket, the bracket can be fixed on circuit breaker case.The pole-mounted circuit breaker, including it is disconnected
Road device cabinet, the box of the circuit breaker body is interior to be equipped with main shaft, which is characterized in that the main shaft is equipped with strip-shaped baffle, above-mentioned
The bracket of pole-mounted circuit breaker brake separating buffer device be fixedly connected with circuit breaker case, the strip-shaped baffle can be in the band of main shaft
Oil bumper is hit under dynamic in breaker open operation and is separated in breaker closing with oil bumper.
But there is also disadvantages once for above-mentioned technical proposal: 1, since oil bumper to be arranged in circuit breaker case
Portion, thus the rubbing action of the oil liquid and damping hole in buffering course in oil bumper and generate a large amount of heat and be difficult to distribute
The outside of circuit breaker case out is be easy to cause in box of the circuit breaker body to be easy to make to save bit by bit a large amount of heat in circuit breaker case
The case where portion catches fire；2, due to using oil bumper, and the oil liquid used in general oil bumper is easy to happen burning, such as resolute
Road device catch fire problem when, the oil liquid in oil bumper only can further increase the serious conditions to catch fire.
Summary of the invention
The purpose of the present invention is to provide a kind of pole-mounted circuit breakers, it is intended to solve pole-mounted circuit breaker in the prior art due to
Oil bumper has been arranged in the inside of circuit breaker case, therefore oil liquid in buffering course in oil bumper and damping hole
Rubbing action and generate a large amount of heat and be difficult to give out the outside of circuit breaker case, to be easy to make to save bit by bit in circuit breaker case
A large amount of heat, be easy to cause the case where catching fire inside circuit breaker case；Due to using oil bumper, and in general oil bumper
The oil liquid of use is easy to happen burning, if breaker catches fire when problem, the oil liquid in oil bumper only can be further
The problem of increasing the serious conditions to catch fire.
To achieve the above object, the present invention adopts the following technical scheme: the pole-mounted circuit breaker includes:
For the main shaft mobile in breaker open operation and combined floodgate；
The cylindricality hollow body being connected on box of the circuit breaker external surface；
The shaft being rotatably installed at the axial location of cylindricality hollow body；
The revolving fragment for being arranged in cylindricality hollow body and being fixedly connected with shaft；
It is arranged in the hollow intracorporal nonflammable liquid of cylindricality；
It is provided with the damping hole on revolving fragment and for passing through nonflammable liquid；
For the movement of main shaft to be converted to the transmission mechanism of the rotation of shaft.
The transmission mechanism includes the gear being fixedly and coaxially connected with shaft, engages the rack gear and rack gear connecting with gear
The connector that is fixedly connected, the body being fixedly connected on main shaft and the upright bar for connecting body and connector.
The inside of circuit breaker case is arranged in the main shaft, and the lower external face of circuit breaker case is arranged in the rack gear,
The strip-shaped hole for passing through upright bar is offered on the downside wall body of the circuit breaker case.
The cover board for covering strip-shaped hole is connected in the upright bar.
It is fixedly connected with the shell for accommodating gear on the cylindricality hollow body, offers on shell for wearing rack gear
The through-hole crossed.
The outer surface of the cylindricality hollow body is connected with heat radiating fin.
The damping hole is arranged far from the side of circuit breaker case.
The revolving fragment is connect by elastic component with the inner wall of cylindricality hollow body.
The elastic component is tension spring.
The nonflammable liquid is silicone emulsion or mercury.
The beneficial effects of the present invention are:
1, when pole-mounted circuit breaker carries out separating brake and closes a floodgate, main axle moving at this time, then by the effect of transmission mechanism, make shaft into
Row rotation, thus rotate revolving fragment in cylindricality hollow body around shaft, it is nonflammable due to being equipped in cylindricality hollow body
Liquid is burnt, and offers damping hole on revolving fragment, therefore nonflammable liquid can be made during revolving fragment is rotated
By damping hole, mechanical energy when rotating revolving fragment calmly is converted to easy firing liquid by rubbing between molecule when damping hole
And the thermal energy formed makes main shaft have preferable buffering effect to play the effect of buffering；
2, since the outside of circuit breaker case is arranged in cylindricality hollow body, then the heat inside cylindricality hollow body can be made quick
It distributes, and is nonflammable liquid in cylindricality hollow body, so that nonflammable liquid is difficult to happen burning, therefore can guarantee open circuit
The inside of device cabinet will not save bit by bit more heat, prevent pole-mounted circuit breaker from the risk of fire occurs, improve pole-mounted circuit breaker
Security performance.
