Abstract
The utility model discloses lightweight composite insulators, including plug, metal termination and insulating sheath, the metal termination is connect with plug upper end, the insulating sheath is coated on mandrel surface, the insulating sheath includes the first insulating layer being made of SMC material and the silicon rubber second insulating layer that is externally provided in the first insulating layer, the second insulating layer is formed by two kinds of different size of umbrella skirt constructions are spaced, and the upper surface of the umbrella skirt construction and lower surface are inclined-plane, at the umbrella rib of umbrella skirt construction and junction is arc structure, ceramic coating is coated with outside the second insulating layer.The insulator of the utility model keeps its electric property reliable and stable, explosion-proof performance is good by the way that dielectric layers are arranged；Sheath body is made by using rubber material, keeps its light-weight, it is at low cost；Two kinds of specifications are designed as by the coated ceramic coating outside second insulating layer, and by umbrella skirt construction, keep insulator easy to clean.
Description
Technical field
The utility model belongs to that electric power is defeated, power transformation equipment technical field, is related to lightweight composite insulator.
Background technology
A critical piece of the insulator as arrester is widely used general but traditional insulator and exists mostly such as
Lower disadvantage：Electric stability and explosion-proof are poor, and service life is short；Insulator surface easy tos produce contamination, causes pollution flashover phenomenon；Absolutely
Edge sheath is made of ceramic material or glass, and weight is big.Therefore, traditional insulator needs further to be improved.
Invention content
The utility model is in view of the deficiencies of the prior art, and it is an object of the present invention to provide a kind of electric stability and explosion-proof are good, again
Measure insulator light, easy to clean.
The technical solution adopted in the utility model is as follows：Lightweight composite insulator, including plug, metal termination and insulation shield
Set, the metal termination connect with plug upper end, and the insulating sheath is coated on mandrel surface, the insulating sheath include by
The first insulating layer and the silicon rubber second insulating layer being externally provided in the first insulating layer that SMC material is constituted, the second insulating layer
It is formed by two kinds of different size of umbrella skirt constructions are spaced, and the upper surface of the umbrella skirt construction and lower surface are oblique
Face, at the umbrella rib of umbrella skirt construction and junction is arc structure, and ceramic coating is coated with outside the second insulating layer.
Further, the thickness of first insulating layer is 8-13mm.
Further, the second insulating layer is by silicon rubber one-time cast-forming.
Further, the angle of inclination of the umbrella skirt construction upper surface and lower surface is respectively 15 ° and -15 °.
Further, the diameter ratio of the different size of umbrella skirt construction is 1:1.5.
Further, the thickness of the ceramic coating is 3-5mm.
The beneficial effects of the utility model are：The insulator of the utility model makes its electricity by the way that dielectric layers are arranged
Gas is stable and reliable for performance, and explosion-proof performance is good；Sheath body is made by using rubber material, keeps its light-weight, it is at low cost；Pass through
The coated ceramic coating outside second insulating layer, and umbrella skirt construction is designed as two kinds of specifications, keep insulator easy to clean.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
1-metal termination in figure, 2-plugs, the 3-the first insulating layer, 4-second insulating layers, 5-umbrella skirt constructions, 6-potteries
Porcelain coating.
Specific implementation mode
Below in conjunction with the accompanying drawings and embodiment is described in further detail the utility model.
As shown in Figure 1, it is the lightweight composite insulator of the utility model, including plug, metal termination and insulating sheath,
Metal termination is connect with plug upper end, and insulating sheath is coated on mandrel surface, and insulating sheath includes first be made of SMC material
Insulating layer and the second insulating layer by silicon rubber one-time cast-forming being externally provided in the first insulating layer, the thickness of the first insulating layer
For 8-13mm, second insulating layer is 1 by two kinds of diameter ratios:The 1.5 spaced composition of umbrella skirt construction, and umbrella skirt construction is upper
Surface and lower surface are inclined-plane, and angle of inclination is respectively 15 ° and -15 °, and at the umbrella rib of umbrella skirt construction and junction is circular arc
Structure, second insulating layer are coated with the ceramic coating that thickness is 3-5mm outside.
The insulator of the utility model keeps its electric property reliable and stable, explosion-proof performance is good by the way that dielectric layers are arranged；
Sheath body is made by using rubber material, keeps its light-weight, it is at low cost；By outside second insulating layer coated ceramic apply
Layer, and umbrella skirt construction is designed as two kinds of specifications, keep insulator easy to clean.
