Description
Technical field
The utility model relates to a kind of minute brake system, specifically, relates to a kind of branch brake system of high-pressure vacuum breaker.
Background technology
High-pressure vacuum breaker is a kind of common high voltage switchgear, and it controls the on off operating mode of voltage in the electrical system through separating brake with closing a floodgate, and therefore, dividing brake system is one of core system of vacuum circuit-breaker.
In present high-pressure vacuum breaker, divide brake system to be generally single brake system that divides.This minute brake system is mainly by tripping electromagnet, connecting lever with hold up son and constitute, and its structure or more complicated seem very too fat to move; Simple in structure, but its power power dissipation is very big again, the reliability of separating brake is very low, and a promptly existing minute brake system is difficult to realizing taking into account aspect structure and the reliability two.
Summary of the invention
The purpose of the utility model is to provide a kind of branch brake system of high-pressure vacuum breaker, in the simple while of implementation structure, guarantees that its reliability reaches kilter.
To achieve these goals, the technical scheme of the utility model employing is following:
The branch brake system of high-pressure vacuum breaker; Comprise the overcurrent electromagnet above the tripping electromagnet that is installed on support below and the support; And through the connecting lever of Bearing Installation on support; Simultaneously, at the switching-off device that also is provided with on the said support between said tripping electromagnet and said overcurrent electromagnet.
Further, said switching-off device comprises the separating brake rotating shaft that is installed on the support, is installed on the bent plate in this separating brake rotating shaft, and respectively with this bent plate and said connecting lever over against in the middle of system.
Further, said separating brake rotating shaft be one through rolling bearing be installed on the support the axle, said bent plate is installed on this axle.
In order to improve reliability, on the said axle manual brake separating plate is installed also.
For easy to operate, the opening button that is connected with the separating brake rotating shaft is installed also on the said support.
Compared with prior art, the utlity model has following beneficial effect:
1, the utility model design is ingenious, simple in structure, easy to operate, and production cost is low;
2, the utility model utilizes the rotation of separating brake rotating shaft; Bent plate is moved; Drive with it over against in the middle of the action of system, and then make and rectify right connecting lever with middle system one and rotate, finally reach the effect of impelling stopping means to kill buffer, realization separating brake; In whole process, the separating brake rotating shaft utilizes bearing to realize that the resistance of separating brake process minimizes dexterously, and has guaranteed that each separating brake point is evenly stressed, thereby has improved the reliability of separating brake effectively;
3, the utility model is as one of core system of high-pressure vacuum breaker, and its application in vacuum circuit-breaker can effectively improve the performance of vacuum circuit-breaker, thereby improves in fact with being worth.
Description of drawings
Fig. 1 is the front view of the utility model.
Fig. 2 is the end view of the utility model.
Fig. 3 is the structural representation of separating brake rotating shaft in the utility model.
Fig. 4 is the structural representation of bent plate in the utility model.
In the above-mentioned accompanying drawing, Reference numeral corresponding components title is following:
The 1-support, 2-tripping electromagnet, 3-overcurrent electromagnet, 4-connecting lever, system in the middle of the 5-bent plate, 6-, 7-axle, 8-manual brake separating plate, 9-opening button, 10-rolling bearing, 11-stopping means.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further, the execution mode of the utility model includes but not limited to the following example.
Like Fig. 1～shown in Figure 4, the branch brake system of high-pressure vacuum breaker mainly comprises tripping electromagnet 2, overcurrent electromagnet 3, connecting lever.Wherein, said tripping electromagnet 2 and overcurrent electromagnet 3 are installed on the below and the top of a support 1 respectively, and tripping electromagnet 2 bottoms are equipped with returning spring.Said connecting lever 4 passes through a Bearing Installation on this support 1, and can this bearing be the fulcrum rotation.Through rotation, an end of connecting lever 4 can contact with the stopping means 11 of its below, and impels its buffer that compresses vacuum circuit-breaker, realizes separating brake.
For when realizing the separating brake effect, guarantee that each the separating brake point in the separating brake process is evenly stressed, to improve the reliability of separating brake, a cover switching-off device is installed also on support.This switching-off device comprises separating brake rotating shaft, bent plate, middle system.Wherein, the separating brake rotating shaft is installed between overcurrent electromagnet and the tripping electromagnet, be one through rolling bearing 10 be installed on the support 1 the axle 7, bent plate 5 is installed on this axle 7, and can drive the axle 7 rotations; Below bent plate 5, be equipped with one rotating in the middle of system son 6, the two ends of this centre system 6 respectively with bent plate 5 and connecting lever 4 over against, sub 6 the time when this centre system of rotation, can impel bent plate 5 and connecting lever 4 rotations.
In addition,, prevent that automatic brake separating from breaking down to cause the branch brake system to work, on above-mentioned axle 7, manual brake separating plate 8 is installed, opening button 9 is installed on support 1 in order to improve the reliability of separating brake.
Under the course of action of the utility model:
When the overcurrent electromagnet is started working, the bent plate 5 on the impact groove 7, bent plate 5 rotates, and drives axle 7 and rotates, and simultaneously, centre system 6 is pressed down, and makes it begin to clockwise rotate; When centre system 6 turns to horizontal level; Itself and connecting lever 4 are separated fully; At this moment, the main shaft that connecting lever 4 will begin with vacuum circuit-breaker is that rotating shaft clockwise rotates, when it turns to the appropriate location; Stopping means 11 on the main shaft carries out spacing to the buffer below it, finally realize system's separating brake.In whole process, axle 7 has formed effectively and has cooperated with bent plate 5, middle system 6, makes each separating brake point stressed evenly, has guaranteed the reliability of separating brake.
According to the foregoing description, just can realize the utility model well.
