Abstract
The utility model discloses a kind of isolation knife insulation rotating shaft anti-tracking structure, comprise isolation knife moving contact and isolation knife fixed contact that three-phase be arranged in parallel, wherein said isolation knife moving contact is all fixed in an insulation rotating shaft, it is characterized in that: in described insulation rotating shaft, corresponding described isolation knife moving contact is provided with fixing station, described fixing station both sides are provided with irregular ellipse, form a fluting between the irregular ellipse of adjacent two-phase, described fluting internal fixtion has epoxy resin dividing plate.The insulation rotating shaft of this anti-tracking structure in isolation knife structure arranges irregular ellipse, and epoxy resin dividing plate is set between the irregular ellipse of adjacent phase, effectively prevent the generation of creepage phenomenon, the use of respective switch cabinet is operated safer, reliable, also will be extended the useful life of respective switch cabinet simultaneously.
Description
Technical field
The utility model relates to installation structures field, is specially a kind of isolation knife insulation rotating shaft anti-tracking structure.
Background technology
The isolation knife insulation rotating shaft of existing switch cubicle is simple use insulating material, and what cause creepage phenomenon is because insulated part surface attachment is filthy, and insulated part dielectric strength is declined, and there was dampness in the air, easily generation is creepage.The of long duration damage that also can cause insulating, thus have influence on the life-span of switch cubicle and jeopardize the personal safety of operator.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the utility model provides a kind of isolation knife insulation rotating shaft anti-tracking structure, effectively prevent creepage phenomenon, make switch cubicle safer, reliable in use operation, also ensure the personal safety of operator simultaneously.
The utility model solves the technical scheme that its technical problem adopts:
A kind of isolation knife insulation rotating shaft anti-tracking structure, comprise isolation knife moving contact and isolation knife fixed contact that three-phase be arranged in parallel, wherein said isolation knife moving contact is all fixed in an insulation rotating shaft, it is characterized in that: in described insulation rotating shaft, corresponding described isolation knife moving contact is provided with fixing station, described fixing station both sides are provided with irregular ellipse, form a fluting between the irregular ellipse of adjacent two-phase, described fluting internal fixtion has epoxy resin dividing plate.
As the improvement of technique scheme, described fixing station is provided with internal screw thread, its installation for isolation knife moving contact is fixed.
The beneficial effect that the utility model brings has:
The insulation rotating shaft of this anti-tracking structure in isolation knife structure arranges irregular ellipse, and epoxy resin dividing plate is set between the irregular ellipse of adjacent phase, increase creepage distance in isolation knife insulation rotating shaft, effectively prevent the generation of creepage phenomenon, the use of respective switch cabinet is operated safer, reliable, also will be extended the useful life of respective switch cabinet simultaneously.
Accompanying drawing explanation
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail,
Accompanying drawing 1 is insulation pivot structure schematic diagram of the present utility model;
Accompanying drawing 2 is primary structure schematic diagrames of the present utility model;
Accompanying drawing 3 is embody rule example structure schematic diagrames of the present utility model.
Embodiment
With reference to accompanying drawing 1 and accompanying drawing 2, the utility model is a kind of isolation knife insulation rotating shaft 3 anti-tracking structure, it comprises isolation knife moving contact 1 and isolation knife fixed contact 2 that three-phase be arranged in parallel, wherein isolation knife moving contact 1 one end connects isolation knife fixed contact 2, the other end is fixed on the fixing station place of insulation rotating shaft 3, the both sides of this fixing station are provided with irregular oval 31, form a fluting between making irregular oval 31 of adjacent two-phase, and namely epoxy resin dividing plate 4 is installed in this fluting.
For ensureing structural stability, fixing station is provided with internal screw thread 32, for fixing isolation knife moving contact 1.
The insulation rotating shaft 3 of this anti-tracking structure in isolation knife structure arranges irregular oval 31, and epoxy resin dividing plate 4 is set between irregular oval 31 of adjacent phase, the former can increase the creepage distance in isolation knife insulation rotating shaft 3, the latter can prevent isolation knife insulation rotating shaft 3 from occurring creepage phenomenon between phase and phase when breaking-closing operating, the use of respective switch cabinet is operated safer, reliable, also will be extended the useful life of respective switch cabinet simultaneously.
In concrete Application Example, with reference to accompanying drawing 3, above isolation knife fixed contact 2, fix main bus bar overlap joint row 5, fixed insulation 6 and fixed insulation daughter board 7 successively.The on/off switch of isolation knife realizes by rotating insulation rotating shaft 3, set up between phase and phase in epoxy resin dividing plate 4 and insulation rotating shaft 3 in isolation knife and set up irregular oval 31, prevented the generation of creepage phenomenon by double hyer insulation, thus ensure the personal safety of operator.
It should be noted that, the above is preferred embodiment of the present utility model, and the utility model is not limited to above-mentioned execution mode, as long as it reaches technique effect of the present utility model with identical means, all should belong to protection range of the present utility model.
