Abstract
The utility model discloses a composite hollow insulator including an upper flange, a lower flange, a glass steel cylinder and a silicon rubber composite umbrella cover. The upper flange and the lower flange are arranged on the upper end and the lower end of the glass steel cylinder respectively. The glass steel cylinder is coiled with glass fiber cloth and is solidified and formed through epoxy pouring in a vacuum condition. The silicon rubber composite umbrella cover made of liquid-state silicon rubber and formed in a single injection molding process is arranged on the surface of the glass steel cylinder. The composite hollow insulator provided by the utility model has comparatively high mechanical strength. And possibility of containing bubbles is extremely small, so that electric performance is good.
Description
Technical field
The utility model relates to a kind of composite hollow insulator.
Background technology
The insulator of High-Voltage Electrical Appliances is being born the double action of High-Voltage Insulation electric loading and mechanical load simultaneously, mainly contains following unsafe factor:
1, the hydrophily of insulator causes forming continuous moisture film on overcast and rainy insulator surface, and especially in the heavy pollution area, the probability that makes the insulator surface that flashover occur increases greatly;
2, be subjected to the porcelain shell for circuit breaker that interior pressure is higher, large-scale bonding gas-filled type insulator, because of porcelain defect or transhipment error, can cause porcelain piece to have hidden danger, cracking or blast during operation.
In recent years, the application of composite hollow insulator on power industry is ripe day by day, and consumption is also increasing,
Such as the GIS outlet casing tube, transformer sleeve pipe external insulation, composite post insulator etc.At present, the maximum molding mode of glass fibre reinforced plastic cylinder materials'use of composite hollow insulator mainly contains hand pasting forming, compression molding, pultrusion, fiber winding forming method etc., composite bushing glass fibre reinforced plastic cylinder used is mostly the manufacture of fiber winding forming method, is also one of main manufacturing process of polymer matrix composites.Its principle for adopt special Wiring apparatus by after continuous fiber or glass fiber impregnating resin glue, be wrapped in continuously, evenly and regularly core or in be lining with, then under the uniform temperature environment, make it curing molding.
Mainly there is following problem in the glass fibre reinforced plastic cylinder that this manufacture is produced:
1, equipment and specification requirement are high, and investment is large, is only applicable to produce in enormous quantities revolution shape.
2, the goods normality is manufactured, and internal air gap is difficult to avoid, and is applied to electric insulation industry defective obvious.
Summary of the invention
The purpose of this utility model is to provide a kind of composite hollow insulator, is entwined with glass fiber, and this composite hollow insulator is used the epoxy casting curing molding with mould under vacuum state, have higher mechanical performance and good electric property.
The purpose of this utility model is achieved through the following technical solutions:
A kind of composite hollow insulator, it is characterized in that: this composite hollow insulator comprises the compound umbrella cover of upper flange, lower flange, glass fibre reinforced plastic cylinder and silicon rubber, upper flange and lower flange are separately positioned on the two ends up and down of glass fibre reinforced plastic cylinder, described glass fibre reinforced plastic cylinder is wound around by glass fabric, and uses the epoxy casting curing molding under vacuum state; The compound umbrella cover of silicon rubber by fluid silicone rubber shot moulding is arranged on the glass fibre reinforced plastic cylinder surface.
In the utility model, described upper flange, lower flange and glass fibre reinforced plastic cylinder mucilage binding hermetically are in the same place.The described glass fibre reinforced plastic cylinder surface compound umbrella cover of fluid silicone rubber shot molding silicone rubber.
Compared with prior art, glass fibre reinforced plastic cylinder of the present utility model is entwined with glass fiber, under vacuum state, uses the epoxy casting curing molding with mould, has higher mechanical strength.The composite hollow insulator glass fibre reinforced plastic cylinder is moulding by casting under vacuum condition, and the possibility of inner clip bubble is minimum, excellent electrical properties.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
A kind of composite hollow insulator described in the utility model, comprise lower flange 1, glass fibre reinforced plastic cylinder 2, silicon rubber composite sheath 3 and upper flange 4; Wherein upper flange 4 and lower flange 1 aluminium alloy casting, glass fibre reinforced plastic cylinder 2 use glass fibers are entwined, and put into mould and under vacuum state, use the epoxy casting curing molding, are processed into and require with the flange mucilage binding, to be in the same place after size, guarantee sealing; Finally on glass infuser 2 surfaces, once use the compound umbrella cover 3 of fluid silicone rubber shot molding silicone rubber.
