Abstract
The utility model relates to an insulating tube for a load switch isolating grounding switch. The tube comprises a main body with an inner cavity made of insulating material. The upper end of the main body is open, and the bottom is provided with a vertical through hole communicating with the inner cavity of the main body. A wire outlet seat with a horizontal through hole communicating with the inner cavity of the main body is arranged on a side wall of the main body. The tube is characterized in that the side wall of the main body under the wire outlet seat dents towards the interior of the main body to form a transverse groove. The tube occupies only a small space of a breaker cabinet, so that the size of the breaker cabinet is reduced.
Description
Technical field
The utility model relates to the power transmission and distribution parts that a kind of AC-HVDC and distribution network use, and is the insulating cylinder body that is positioned at the gas holder that opens circuit and is used for holding on-load switch isolation earthing switch specifically.
Background technology
Manufacturing at power transmission and distribution device all knows, for the on-load switch isolation earthing switch in breaker cabinet can better be used, people conventionally can be to on-load switch isolation earthing switch installing insulating cylindrical shell.
At present, the on-load switch isolation earthing switch insulating cylinder body using in industry comprises body, and this body has inner chamber, it is similar to complete cuboid, and it is made up of insulating material, and the upper end of described body is opening-like, vertical through holes, the intracavity inter-connection of this vertical through holes and body are arranged at its bottom.On a sidewall of described body, have wire outlet seat, wire outlet seat has cross through hole, the intracavity inter-connection of this cross through hole and body.This on-load switch isolation earthing switch insulating cylinder body in use, because this on-load switch isolation earthing switch insulating cylinder body is similar to a complete cuboid, so that he accounts for the space of the gas holder that opens circuit is just large.And this on-load switch isolation earthing switch insulating cylinder body is in breaker cabinet and when solid insulation fuse cylindrical shell matches, its position meeting and the position of solid insulation fuse cylindrical shell blind end interfere with each other, and for fear of this interference breaker cabinet, just must increase volume holds them.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of on-load switch isolation earthing switch insulating cylinder body, adopts the space of the shared breaker cabinet of this insulating cylinder body little, reduces the volume of breaker cabinet.
For addressing the above problem, take following technical scheme:
On-load switch isolation earthing switch insulating cylinder body of the present utility model comprises body, and body has inner chamber, and it is made up of insulating material.The upper end of described body is opening-like, and vertical through holes, the intracavity inter-connection of this vertical through holes and body are arranged at its bottom.On a sidewall of described body, have wire outlet seat, wire outlet seat has cross through hole, the intracavity inter-connection of this cross through hole and body.The body sidewall that is characterized in described wire outlet seat below to its inner recess to form horizontal groove.
Wherein, described wire outlet seat is tubulose and is horizontal arrangement.On the body sidewall of described wire outlet seat top, there is observation panel.Described body is mutually docked and forms by two shape symmetries, the identical body unit of size.
To be coated with layer of semiconductor glue or conducting metal on the outer wall of described body and wire outlet seat to further improvement of the utility model scheme.Improved like this advantage is to prevent from occurring accumulation of static electricity phenomenon on the outer wall of body and wire outlet seat.
Adopt above scheme, have the following advantages:
Due to the body sidewall of on-load switch isolation earthing switch insulating cylinder body wire outlet seat of the present utility model below to its inner recess to form horizontal groove.So the space of the shared breaker cabinet of this on-load switch isolation earthing switch insulating cylinder body is relatively little.And it is in breaker cabinet and when solid insulation fuse cylindrical shell coordinates, groove on it can be used for the blind end of holding solid insulation fuse cylindrical shell, eliminate in breaker cabinet the interference of it and solid insulation melt device cylindrical shell blind end, just do not need to increase volume holds them to breaker cabinet, and the volume of breaker cabinet is reduced.
Brief description of the drawings
Fig. 1 is the structural representation of on-load switch isolation earthing switch insulating cylinder body of the present utility model;
Fig. 2 is the upward view of Fig. 1;
Fig. 3 is that the A-A of Fig. 2 is to cutaway view.
Embodiment
Below in conjunction with accompanying drawing, on-load switch isolation earthing switch insulating cylinder body of the present utility model is described in further detail.
Shown in Fig. 1, Fig. 2 and Fig. 3, on-load switch isolation earthing switch insulating cylinder body of the present utility model comprises body 1, and body 1 is similar to flat cuboid, and it is vertical.Described body 1 have inner chamber and upper end opening-like.For convenient processing and installation, body 1 described in the present embodiment is formed by two shape symmetries, the big or small identical mutual docking of body unit 7, and body 1 is made up of insulating material.Described body 1 bottom is processed with vertical through holes 2, the intracavity inter-connection of this vertical through holes 2 and body 1.On a sidewall of described body 1, there is wire outlet seat 3, on wire outlet seat 3, be processed with cross through hole 4, the intracavity inter-connection of this cross through hole 4 and body 1.Body 1 sidewall of described wire outlet seat 3 belows to form horizontal groove 5, makes body 1 longitudinal section below wire outlet seat be similar to right-angled trapezium to its inner recess.In the present embodiment, described wire outlet seat 3 is for tubulose and be horizontal arrangement.On body 1 sidewall of described wire outlet seat 3 tops, be processed with observation panel 6.On the outer wall of described body 1 and wire outlet seat 3, be coated with layer of semiconductor glue or conducting metal.
When use, on-load switch isolation earthing switch insulating cylinder body of the present utility model is vertical in breaker cabinet, its wire outlet seat 3 is connected with the inlet wire seat on fixed insulation fuse cylindrical shell in breaker cabinet, and groove 5 is used for holding the blind end of fixed insulation fuse cylindrical shell.
