Background technology
High, medium and low voltage breaker in current coal mine explosion-proof distribution system and contactor, generally comprise three vacuum switch tubes and one for synchronously driving the vertical permanent magnet driving mechanism of three synchronous divide-shut brakes of vacuum switch tube, vertical permanent magnet driving mechanism is generally by rotating shaft lever technique or used rotation connecting lever to realize synchronously driving multiple vacuum switch tube.The former needs to increase the total height of circuit breaker, and its technical difficulty is large and technology is also immature in addition; The latter needs to increase guider could realize linear drives, and so not only complex structure, cost are high, and functional reliability, stability are also poor.
Utility model content
The purpose of this utility model is to provide a kind of permanent magnet mechanism circuit-breaker that can effectively reduce whole height.
The technical scheme realizing the utility model object is: a kind of permanent magnet mechanism circuit-breaker, comprises framework and is arranged on vacuum switch tube arranged in parallel on framework, insulated tension pole, three insulators, three permanent magnet type drive mechanism, rotating shaft, two tripping springs and six divide-shut brake connecting levers being provided with push rod; The push rod of permanent magnet type drive mechanism is horizontally disposed with, vertical with the direction of motion of vacuum switch tube dynamic/static contact divide-shut brake, forms horizontal type structure; Axis of rotation is arranged in the frame, and six connecting lever combination of two use, and forms three cover connecting lever assemblies; Each cover connecting lever assembly uses with an insulated tension pole adaptation respectively; Each connecting lever middle-end is sheathed and be fixedly installed in rotating shaft, and its underarm is rotationally connected by the push rod of bearing pin and permanent magnet type drive mechanism, and its upper arm is connected by the bottom of bearing pin with each insulated tension pole.
In such scheme, linked by a synchronizing shaft arranged with shaft parallel in the lower end of the underarm of each connecting lever.
In such scheme, the top of each tripping spring is set in the end of the upper arm of a corresponding connecting lever, and insulated tension pole then between the top and rotating shaft of tripping spring, and is arranged close to tripping spring top; The bottom of each tripping spring is articulated in base of frame.
In such scheme, rotating shaft is positioned at the side of the bottom of insulated tension pole, and is in contour position with insulated tension pole bottom.
The utility model has positive effect: (1) the utility model synchronously drives three vacuum switch tube divide-shut brakes owing to adopting a Horizontal permanent-magnetic driving mechanism, thus the rotating shaft being need not be arranged on immediately below vacuum switch tube, circuit breaker whole height can be reduced to greatest extent; (2) the utility model structure is comparatively compact and simplify, and makes this product more reliable, can be widely used in colliery with in the distribution system of explosion-resistant enclosure.(3) this product adopts the mentality of designing of quick inserting mode and integrated modular, vacuum tube with connect electroplax and be connected, thus effective compression volume space.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is that circuit breaker shown in Fig. 1 is from a kind of structural representation during another angle views.
Embodiment
(embodiment 1)
Fig. 1 and Fig. 2 shows a kind of embodiment of the present utility model, and wherein Fig. 1 is a kind of structural representation of the present utility model; Fig. 2 is that circuit breaker shown in Fig. 1 is from a kind of structural representation during another angle views.
Present embodiment discloses a kind of permanent magnet mechanism circuit-breaker, see shown in Fig. 1 and Fig. 2, comprise framework 1, be arranged on permanent magnet type drive mechanism 4, rotating shaft 51, two tripping springs 52 and six divide-shut brake connecting levers 53 that on framework three 35, three, vacuum switch tube 2, three insulated tension poles 31, three touch springs 32, three insulators arranged in parallel are provided with push rod 41.
See shown in Fig. 1 and Fig. 2, each vacuum switch tube along plumb line direction arrange, fixed contact upper, moving contact under; The tip portion that fixed contact wherein stretches out vacuum switch tube shell by bolt assembly with on connect electroplax 33 fixing together with and realize being electrically connected, moving contact then by be flexible coupling with under connect electroplax 34 and be electrically connected.
The upper end of each insulated tension pole is connected with the moving contact of a corresponding vacuum switch tube by an insulator, and each touch spring is set on a corresponding insulated tension pole.
The push rod level of three permanent magnet type drive mechanisms and be arrangeding in parallel, all vertical with the direction of motion of vacuum switch tube dynamic/static contact divide-shut brake, form horizontal type structure; Axis of rotation is arranged in the frame, and six connecting lever combination of two use, and forms three cover connecting lever assemblies; Each cover connecting lever assembly uses with an insulated tension pole adaptation respectively; Each connecting lever from the side its basic configuration is in the shape of the letter V; Linked by a synchronizing shaft arranged with shaft parallel in the lower end of each connecting lever underarm.
As shown in Figure 1, the middle-end of each connecting lever is sheathed and be fixedly installed in rotating shaft, and the underarm 531 of each connecting lever is rotationally connected by the push rod of bearing pin and permanent magnet type drive mechanism, and the upper arm 532 of each connecting lever is connected by the bottom of bearing pin with a corresponding insulated tension pole.In the present embodiment, the angle that the upper arm of each connecting lever and underarm are formed preferably 70 degree to 90 degree, certainly, adopts the connecting lever of other angle to be also feasible.
As shown in Figure 1, the top of two tripping springs is set in the end of the upper arm of in two connecting levers in right side corresponding separately, insulated tension pole then between the top and rotating shaft of tripping spring, and is arranged close to tripping spring top, and the bottom of each tripping spring is articulated in base of frame.
In the present embodiment, rotating shaft is not positioned at immediately below vacuum switch tube, but be positioned at the side of the bottom of insulated tension pole, and be in contour position with insulated tension pole bottom, this structure has following beneficial effect: whole height is determined by the circumference external diameter of the stroke height of vacuum switch tube, insulated tension pole, dynamic/static contact divide-shut brake and permanent magnet type drive mechanism housing, the lowermost end of its insulated tension pole very close to the top of magneto drive shell, thus can reduce whole height to greatest extent.
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to execution mode of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all execution modes.And these belong to connotation of the present utility model the apparent change of extending out or variation still belong to protection range of the present utility model.
