Abstract
The utility model discloses a double-lock-catch busbar insulating sheath, and aims at solving the problems that a conventional transformation busbar insulating structure is relatively low in working efficiency, requires relatively large connection area, needs more silicone rubber adhesive, and the like. One side of one surface of a sheath (2) is provided with a bulge (1) with a T-shaped cross section, the bulge (1) and the sheath (2) are connected together, the other side of the same surface of the sheath (2) is provided with a ridge (3), and a groove with a U-shaped cross section is arranged on the ridge (3). The double-lock-catch busbar insulating sheath has the advantages of facilitating clamping, improving efficiency, reducing the using amount of the silicone rubber adhesive, and the like.
Description
Technical field
The utility model relates to a kind of insulation system, especially relates to a kind of twin-lock button busbar insulating sleeve.
Background technology
At present; A kind of like this power transformation busbar insulation system is disclosed on the market; Its design feature is: be made up of left sheath and right sheath, left sheath and right sheath are processed into cross section and are the U shape, on the power transformation busbar surface between insulating sleeve and the power transformation busbar, also are provided with insulating barrier; Between left sheath and right sheath, be provided with the silicon rubber binder; To be processed into cross section by the left sheath opening part inner surface that silicon rubber is processed and be step-like, will be processed into to match with left sheath opening part step-like, be the silicon rubber binder that is provided with 0.2mm between the horizontally disposed step surface at left sheath and right sheath by the right sheath opening part inner surface that silicon rubber is processed.Generation when this structure can effectively reduce the human casualty accident that causes because of pollution flashover, condensation flashover, icing tripping operation, toy short circuit, naked busbar in the transformer station, the reliability of raising electric power system.But, could this insulation system be sleeved on the power transformation busbar, and the limited length of this left and right sides sheath owing to need left and right sides sheath gluing is clamped; Need the position of splicing more; Therefore, operating efficiency is lower, again because the connection area of sheath junction, the left and right sides is bigger; Need more silicon rubber binder, thereby improved cost.
Summary of the invention
The purpose of the utility model provides a kind of convenient mounting and clamping, can raise the efficiency, and can reduce the twin-lock of silicon rubber binder use amount again and buckle the busbar insulating sleeve.
For achieving the above object; The utility model twin-lock button busbar insulating sleeve, one side sheath one surface be provided with the convexity that cross section is T word shape, this convexity is connected one with sheath; Another side on the same surface of sheath is provided with sleeveless jacket, and sleeveless jacket is provided with the groove that cross section is U word shape.
The said protruding upper surface that cross section is T word shape is arranged to the curved surface shape.
The said slot opening both sides that are U word shape at cross section are provided with the bank of being convenient to block convexity.
Said sleeveless jacket height equals busbar thickness.
After adopting this structure, one side since sheath one surface be provided with the convexity that cross section is T word shape, this convexity is connected one with sheath, the another side on the same surface of sheath is provided with sleeveless jacket, sleeveless jacket is provided with the groove that cross section is U word shape.During use,, thereby further improved operating efficiency, reduced the use amount of silicon rubber binder again, reduced cost the groove fit on the convexity on one of them sheath and another sheath.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify.
Accompanying drawing is the main cross-sectional schematic that the utility model twin-lock is buckled the busbar insulating sleeve.
Among the figure: 1. protruding 2. sheaths, 3. sleeveless jackets, 4. grooves.
Embodiment
The twin-lock of the utility model shown in the accompanying drawing is buckled the busbar insulating sleeve; The one side on sheath 2 one surfaces is provided with the convexity 1 that cross section is T word shape; This convexity 1 is connected one with sheath 2, and the another side on sheath 2 same surfaces is provided with sleeveless jacket 3, and sleeveless jacket 3 is provided with the groove 4 that cross section is U word shape; Said protruding 1 upper surface that cross section is T word shape is arranged to the curved surface shape; The said groove 4 opening both sides that are U word shape at cross section are provided with the bank of being convenient to block convexity 1; Said sleeveless jacket 3 highly equals busbar thickness.
Claims (4)
1. twin-lock button busbar insulating sleeve; It is characterized in that: sheath (2) one side a surface be provided with the convexity (1) that cross section is T word shape; This convexity (1) is connected one with sheath (2); Another side on the same surface of sheath (2) is provided with sleeveless jacket (3), and sleeveless jacket (3) is provided with the groove (4) that cross section is U word shape.
