Abstract
The utility model discloses a kind of primary cut-out, comprise housing and the vacuum interrupter, insulated tension pole, the permanent-magnet manipulating mechanism that are arranged on described enclosure interior, described insulated tension pole connects described vacuum interrupter and permanent-magnet manipulating mechanism.Vacuum interrupter is directly connected insulated tension pole one end by the primary cut-out that the utility model provides, the insulated tension pole other end directly connects permanent-magnet manipulating mechanism.In the middle of this structure reduces, each transmission link, permanent-magnet manipulating mechanism are by the direct folding vacuum interrupter of insulated tension pole, are more conducive to that circuit cut-offs, and improve primary cut-out break performance.
Description
Technical field
The utility model relates to high pressure breaking technique field, especially, relates to a kind of direct-connected primary cut-out.
Background technology
Existing primary cut-out is: cut-offfing of vacuum interrupter, and by insulated tension pole one end link arc control device, the other end is connected with connecting lever, and the other end of connecting lever links with permanent-magnet manipulating mechanism.The lever principle moving through connecting lever of permanent-magnet manipulating mechanism is to drive cut-offfing and closing of arc control device.
Referring to Fig. 1, is the planar structure schematic diagram of existing primary cut-out.Described primary cut-out 1 comprises vacuum interrupter 11, insulated tension pole 12, connecting lever 13, fulcrum 14, permanent-magnet manipulating mechanism 15, and described connecting lever 13 connects described vacuum interrupter 11, insulated tension pole 12, fulcrum 14, permanent-magnet manipulating mechanism 15 successively.
When described primary cut-out 1 works, described permanent-magnet manipulating mechanism 15 closing motion, drives described connecting lever 13 to move, and described connecting lever 13 drives described insulated tension pole 12 to move, described insulated tension pole 12 drives described vacuum interrupter 11 to cut-off with closed, reaches open and close object.
Existing primary cut-out running part complex structure, cost of manufacture be high, be unfavorable for cut-offfing of arc control device.
Utility model content
In order to solve the problems of the technologies described above, the utility model provide a kind of structure simple, cost-saving, be beneficial to the primary cut-out that circuit cut-offs.
A kind of primary cut-out, comprise housing and the vacuum interrupter, insulated tension pole, the permanent-magnet manipulating mechanism that are arranged on described enclosure interior, it is characterized in that, described insulated tension pole connects described vacuum interrupter and permanent-magnet manipulating mechanism.
In a kind of preferred embodiment of the present utility model, described housing is insulating barrier.
Compared to prior art, vacuum interrupter is directly connected insulated tension pole one end by the primary cut-out that the utility model provides, the insulated tension pole other end directly connects permanent-magnet manipulating mechanism.In the middle of this structure reduces, each transmission link, permanent-magnet manipulating mechanism are by the direct folding vacuum interrupter of insulated tension pole, are more conducive to that circuit cut-offs, and improve primary cut-out break performance.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the planar structure schematic diagram of prior art primary cut-out.
Fig. 2 is the planar structure schematic diagram of primary cut-out one better embodiment that the utility model provides.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Referring to Fig. 2, is the planar structure schematic diagram of primary cut-out one better embodiment that the utility model provides.Described primary cut-out 2 comprises housing 21 and is arranged on vacuum interrupter 22, insulated tension pole 23, the permanent-magnet manipulating mechanism 24 of described enclosure interior, and described insulated tension pole 23 connects described vacuum interrupter 22 and permanent-magnet manipulating mechanism 24.
In the present embodiment, described housing 21 is insulating barrier, and more specifically, described housing 21 is electro-insulating rubber.
In described primary cut-out 2 course of work, described permanent-magnet manipulating mechanism 24 closing motion, drives described insulated tension pole 23 to move, and described insulated tension pole 23 drives described vacuum interrupter 22 to cut-off with closed, reaches electric current open and close object.Can be understood as, according to character of circuit, configure different primary cut-outs 2, that is, two-phase electricity two described primary cut-outs 2, three-phase electricity three described primary cut-outs 2, do not repeat one by one at this.
Compared to prior art, vacuum interrupter is directly connected insulated tension pole one end by the primary cut-out that the utility model provides, the insulated tension pole other end directly connects permanent-magnet manipulating mechanism.In the middle of this structure reduces, each transmission link, permanent-magnet manipulating mechanism are by the direct folding vacuum interrupter of insulated tension pole, are more conducive to that circuit cut-offs, and improve primary cut-out break performance.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
