Abstract
The utility model provides composite jacket pillar insulator, mainly solves that existing post insulator is easy to crack, volume gas, fragility are large, the problem of poor toughness, dielectric strength and bad mechanical strength.This composite jacket pillar insulator, comprises core body, end coupling and composite sheath, and described core body is by epoxy glass fiber pultrusion, and core body is divided into twice or repeatedly pultrusion.This composite jacket pillar insulator is without layering and bubble, and toughness is high, dielectric strength and mechanical strength high, anti-seismic performance is good, is particularly useful for high voltage field.
Description
Technical field
The utility model relates to the post insulator of power transmission and transformation industry, is specifically related to composite jacket pillar insulator.
Background technology
At present, along with the continuous construction of domestic and international power transmission and transformation industry superhigh pressure project, the requirement of superhigh pressure composite insulator is also improving constantly, particularly to the requirement of mechanical strength.Traditional composite jacket pillar insulator is with epoxy glass fiber drawing and extruding bar for plug, and because it is by the restriction of production technology, large diameter plug not easy-formation, exists the mass defect such as cracking, volume gas, have impact on dielectric strength and the mechanical strength of product.
Summary of the invention
The utility model provides composite jacket pillar insulator, mainly solves that existing post insulator is easy to crack, volume gas, fragility are large, the problem of poor toughness, dielectric strength and bad mechanical strength.
Concrete technical scheme of the present utility model is as follows:
This composite jacket pillar insulator, comprises core body, end coupling and composite sheath, it is characterized in that: described core body comprises center plug, and center plug arranged outside has at least one deck plug covering; Gapless and bubble between described center plug and plug covering.
Above-mentioned center plug and plug covering all pass through pultrusion.
Above-mentioned center plug and plug covering by electrician with alkali-free Non-twisting glass fibre yarn or electrician with alkali-free glass fibre band pultrusion.
Above-mentioned composite sheath is that silicon rubber vulcanization is shaping; Described silicon rubber is firm silicone rubber or liquid silastic.
Advantage of the present utility model is as follows:
The composite jacket pillar insulator plug that the utility model provides is without layering and bubble, and toughness is high, dielectric strength and mechanical strength high, anti-seismic performance is good, is particularly useful for high voltage field.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Accompanying drawing is detailed as follows:
1-core body, 2-composite sheath, 3-end coupling.
Embodiment
This composite jacket pillar insulator, comprises core body, end coupling and composite sheath, and core body comprises center plug, and center plug arranged outside has at least one deck plug covering; Gapless and bubble between described center plug and plug covering.
Center plug and plug covering are by epoxy glass fiber pultrusion, and epoxy glass fiber can be electrician's alkali-free Non-twisting glass fibre yarn or electrician's alkali-free glass fibre band.
Core body is divided into twice or repeatedly pultrusion, epoxy glass fiber pultrusion is the center plug that diameter is relatively little by first time, then at the periphery continuation epoxy glass fiber pultrusion plug covering of the less center plug of diameter, until diameter reaches designing requirement.
Composite sheath is that silicon rubber vulcanization is shaping, and silicon rubber is firm silicone rubber or liquid silastic.
