Abstract
The polytetrafluoroethylene film for being used for busbar insulation of the utility model, includes the thin-film covering of tubular structure, thin-film covering section is substantially rectangular, and the longer side in rectangular section one has longitudinal opening；Two short sides of thin-film covering are arc-shaped to be adapted with busbar edge, can directly it be set in by the film nested structure of opening on busbar, the arc-shaped of two short sides of thin-film covering is to be adapted with busbar edge, it can be coated and fixed and be sleeved on busbar, after suit will not loose or dislocation, coat easy to operate, stable insulation, multi-layer thin Membrane cover can also be used, and reversely overlapping set is overlying on busbar, further improves insulating protection performance.
Description
Technical field
It the utility model is related to a kind of polytetrafluoroethylene film for busbar insulation.
Background technology
The insulating protective layer of busbar in conventional electric power equipment generally uses thermal shrinkage type plastic bushing, by adding after suit
Thermal high-temperature baking pyrocondensation is fixed, or is fixed after being wrapped around banding polytetrafluoroethylene film by tape-stripping, pyrocondensation
Casing suit is inconvenient, and pyrocondensation temperature control is difficult, and banding polytetrafluoroethylene film is wrapped around cumbersome, and also easily loosening causes to wrap
Cover uneven or even come off, humid air easily enters insulating layer from film band gap particularly in moist use environment
It is interior, conductive insulation performance is influenced, protection effect is bad, and insulation performance is unreliable, and system operation security risk is high.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of easy to operate, the stable insulation of cladding, structure
It is simply to the polytetrafluoroethylene film of busbar insulation.
The polytetrafluoroethylene film for being used for busbar insulation of the utility model, includes the thin-film covering of tubular structure, it is special
Sign is：Thin-film covering section is substantially rectangular, and the longer side in rectangular section one has longitudinal opening；
Further, the longitudinal edge of opening both sides, which extends and overlaps each other to opposite side, shelters from opening；
Further, the longitudinal edge of opening both sides extends to identical with the long edge lengths of thin-film covering to opposite side, makes
Obtain one longer side of thin-film covering and form discrete double-decker；
Further into two short sides of thin-film covering are arc-shaped to be adapted with busbar edge.
The polytetrafluoroethylene film for being used for busbar insulation of the utility model, can be straight by the film nested structure of opening
For female connector loaded on busbar, the arc-shaped of two short sides of thin-film covering is to be adapted with busbar edge, and suit can be coated and fixed
On busbar, after suit will not loose or dislocation, coat easy to operate, stable insulation, multi-layer thin Membrane cover can also be used
Reversely overlapping set is overlying on busbar, further improves insulating protection performance.

Embodiment
As shown in the figure, a kind of polytetrafluoroethylene film for busbar insulation, includes the thin-film covering 3 of tubular structure, it is thin
3 section of Membrane cover is substantially rectangular, and the longer side in rectangular section one has longitudinal opening；Pass through the film nested structure energy of opening
Enough to be directly set on busbar, cladding is easy to operate, and can also using multi-layer thin Membrane cover, reversely overlapping set is overlying on busbar,
Specifically, after positive suit cladding thin film set, then reversely suit cladding thin film set, cladding can be busbar twice
Double hyer insulation protective layer is added, it is simple to operate.
Further, the longitudinal edge 1,2 of opening both sides, which extends and overlaps each other to opposite side, shelters from opening portion
Position, it is possible to increase insulating protection performance；Multi-layer thin Membrane cover can also be used, and reversely overlapping set is overlying on busbar, specifically, just
To after suit cladding thin film set, then reversely suit cladding thin film set, cladding can be that busbar adds bilayer twice
Insulating protective layer, busbar middle part thickness of insulating layer are more than edge, improve phase insulation performance.
Further, the longitudinal edge of opening both sides extends to identical with the long edge lengths of thin-film covering to opposite side, makes
Obtain one longer side of thin-film covering and form discrete double-decker；Multi-layer thin Membrane cover can also be used, and reversely overlapping set covers
In on busbar, specifically, after forward direction is set with cladding thin film set, then reversely suit coats thin film set, coats twice
Can be that busbar adds three-layer insulated protective layer, busbar middle part thickness of insulating layer is more than edge, improves phase
Between insulation performance, and the smooth gapless in phase insulation layer contact site.
Further into two short sides of thin-film covering are arc-shaped to be adapted with busbar edge, thin-film covering suit cladding
, can be reliably spacing by radiused edges on busbar, will not loose or dislocation, can also be further solid by tape-stripping
Surely insulating layer is connected, is connected fixed reliable.
The polytetrafluoroethylene film for being used for busbar insulation of the utility model, can be straight by the film nested structure of opening
For female connector loaded on busbar, the arc-shaped of two short sides of thin-film covering is to be adapted with busbar edge, and suit can be coated and fixed
On busbar, after suit will not loose or dislocation, coat easy to operate, stable insulation, multi-layer thin Membrane cover can also be used
Reversely overlapping set is overlying on busbar, further improves insulating protection performance.
Polytetrafluoroethylene film is to be molded, sintered, cooled into blank by polyflon, then through turning, calendering
It is made.Polytetrafluoroethylene film is used as electromechanical manufacture, premium insulation pad, sheath, antifriction material and the chemical industry of electronics industry are prevented
Rotten material etc..It insulate, antiseptic property influences from frequency, temperature, can be at -180 DEG C~+260 DEG C.
