Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described, embodiment does not form limit of the present utility modelSystem:
Long-life mechanism a railway vacuum circuit breaker, it is characterized in that, comprise railway breaker, described railway is disconnectedOn the device of road, comprise the output macro-axis that can turn, on described output macro-axis, be fixed with output toggle arm, the hinged spiral shell in described output toggle arm endBar, described screw rod connects contact stage clip, described contact stage clip attended operation insulator, the hinged guide rod of described operation insulator, behaviourMake insulator and connect guide rod by slip-knot bolt, guide rod upper end comprises moved end, and moved end is positioned at vacuum extinction chamber interior, inWhen gate-dividing state, touch spring is compressed, and in the time that output macro-axis rotates, output toggle arm rotates, and contact stage clip is from pressingContracting state releases energy, and promotes the action of operation insulator, further promotes guide rod motion, and promote moved end and contact with static terminal,Realize and closing a floodgate. The technique effect of the essence that the technical scheme at this place plays and implementation procedure thereof are for as follows: output macro-axis rotatesTime, output toggle arm rotates, and contact stage clip releases energy from compressive state, promotes the action of operation insulator, further promotesGuide rod motion, promotes moved end and contacts with static terminal, realizes and closing a floodgate, and the structure at this place, with respect to original breaker structure, is adoptedCarry out actuating with side, the life-span is between 20000-100000 time.
As an example, on described output macro-axis, connect cam driving structure by connecting rod, cam driving structure can the company of drivingBar motion, further drives output macro-axis to rotate. The implementation at this place is the connecting rod drives structure of present general breaker,Its realization is exemplified below, an existing class high-pressure vacuum breaker, and spring operating mechanism adopts manually or small-power AC electricalMachine energy storage, its switching force is not affected by supply voltage, quite constant, can either obtain higher closing speed, can realize again fastSpeed automatic reclosing operates, and has overcome to a certain extent the shortcoming of electromagnetic operating mechanism. Spring operating mechanism adopts four connecting rodsVersion, in making process, switching-in spring drives the rotation of combined floodgate camshaft, the four connecting rods actions of cam rotary compression driveMain shaft rotates and closes a floodgate. And in separating brake process, separating brake fanning strip rotates, promote four connecting rods by connecting rod, four connecting rods are departed fromPoised state, four connecting rods move rapidly and drive main shaft to rotate separating brake.
As preferably, described vacuum interrupter includes respectively an insulator up and down, and a side of described insulator connectsIn upper end or the lower end of vacuum interrupter, opposite side is on the housing of railway breaker. Described railway breaker below comprisesBase, base below comprises wheel.
As preferably, described operation insulator length is 380mm, and creep age distance is more than 780mm. Consider breakerThe insulator that increases creep age distance has been used in the raising of overall performance on newly-designed breaker, has highly been increased to390mm, creep age distance is increased to 780mm left and right; The operation insulator length of breaker is increased to 380mm, and creep age distance also existsMore than 780mm; Such dielectric level, can reach the service condition of height above sea level 3500M, improves much than original 1000M,Highlands can be used in Qinghai, Xinjiang and the Tibet of China etc.
As preferably, described insulator upper end is to comprise an insulation board, operation insulator on the housing of railway breakerAlso be positioned under insulation board. Insulation board can keep off the rain, prevent rainwater fall operation insulator on.
Described insulation board is towards the insulation board having a down dip. The technique effect of the essence that the technical scheme at this place plays andImplementation procedure is for as follows: insulation board can be led rain, prevents ponding, and insulation effect is better.
Revise with further as summary:
Breaker energy storage process: control loop is connected, energy storage motor obtains electric rotation and drives reductor, finally by energy storage bulletAfter spring elongates and puts in place, closing pawl puts in place, put in place travel switch action of energy storage, and motor is cut off the electricity supply.
The thermal energy storage process of mechanism completes, and possesses combined floodgate condition.
Feed motion: obtain reclosing command, making electromagnet energized action, promotes closing pawl, and energy-stored spring discharges energyAmount, band moving cam, cam curved surface pushing rolling wheels, final drivening rod, connecting rod drives output macro-axis, the output toggle arm circular arc of macro-axisMotion, connects vacuum interrupter by a series of links such as screw rod, operation insulator, slip-knot bolt and guide rods. Contact stage clipCompressed with tripping spring. After combined floodgate puts in place, the sincere sub-sync card of separating brake puts in place, and whole breaker is in "on" position.
Separating brake action: obtain after separating brake instruction, tripping electromagnet action, contact stage clip and tripping spring promotionUnder, the motion in the other direction of output macro-axis, then by a series of links of above-mentioned feed motion, finally make vacuum interrupter disconnect.
After separating brake has moved, breaker enters again thermal energy storage process.
The bulk shape of the mechanism of this patent is little, and internal part has carried out new arranging, and structure is compacter, volume and skyBetween less. With the material of manufacturing casing is thickeied and strengthened. This patent performance is more excellent, and the life-span is longer, care and maintenanceCost is lower.
In a creative way, above each effect independently exists, and can also complete with a nested structure combination of the above results.
It is clear that the technique effect that above structure realizes is realized, if do not consider additional technical scheme, this patent title alsoIt can be a kind of breaker structure.
Not shown part details.
It should be noted that, the basic scheme that multiple schemes that this patent provides comprise itself, separate, not mutualRestriction, but it also can mutually combine in the situation that not conflicting, and reaches multiple effects and jointly realizes.
More than show and described general principle of the present utility model, principal character and advantage of the present utility model. AbilityThe technical staff in territory should understand the utility model and not be restricted to the described embodiments, and in above-described embodiment and description, describesPrinciple of the present utility model is just described, is not departing under the prerequisite of the utility model spirit and scope, the utility model also canHave various changes and modifications, these changes and improvements all fall in claimed scope.
