Abstract
A suspended basin-shaped composite insulator is provided with a hardware base, a hardware pull-rod, as well as a porcelain core bonding together with the hardware base and the hardware pull-rod by adhesive; the outside of the porcelain core is cladded with a protective layer made from silicon rubber; a protective layer on the upper surface of the porcelain core close to the hardware base is stretched outwards to form an upper Ski-pad; the protective layer, which is arranged below the upper Ski-pad and above the lower surface of the porcelain core, is provided with at least one lower Ski-pad stretching outwards. The utility model has the advantages of self-cleaning and high antifouling performance. The surface does not need cleaning; the creepage distance can be enhanced greatly. The utility model is suitable for safety use of 10 to 1000 Kv power supply and substation circuits.
Description
Technical field
The utility model belongs to high pressure for the insulator that uses in the power transformation circuit, particularly a kind of compound suspension insulator.
Background technology:
Insulator is used for high pressure for the power transformation circuit.Present widely used insulator is and suspension insulator, is porcelain (or glass) insulating disc and gold utensil and forms, and the antifouling ability on its surface is lower, the dirt on the cleaning porcelain insulating disc surface that needs often to have a power failure, and very inconvenient and influence is for power transformation efficient.
Summary of the invention
The purpose of this utility model is the above-mentioned shortcoming at prior art, and a kind of compound suspended pot shaped insulator that improves the insulating disc structure is provided.
The technical scheme that realizes the utility model above-mentioned purpose is: compound suspended pot shaped insulator, has the gold utensil seat, the gold utensil pull bar, and the porcelain core that bonds together by adhesive and gold utensil seat and gold utensil pull bar, external packets at porcelain core is covered with the overcoat made from silicon rubber, extend protection plate on laterally at overcoat near the upper surface of the porcelain core of gold utensil seat, below the last protection plate, the lower surface of porcelain core above the overcoat following protection plate that has at least one to extend laterally.
Described protection plate down is the overcoat extension laterally of the lower surface of last protection plate.
Described protection plate down is the overcoat extension laterally of porcelain core sidewall.
Described protection plate down is at least two extensions laterally of overcoat of porcelain core sidewall.
The utility model has the advantages that by the silicon rubber overcoat laterally extend to form upper and lower protection plate, make full use of silicon rubber self-cleaning, antifouling the strong characteristics of ability, do not need again by the power failure clean surface; Structural design is the benzvalene form shape simultaneously, has increased creepage distance greatly, can be fit to the safe handling of 10～1000Kv for the power transformation circuit, also alleviated weight, under equal pulling force situation, can increase the suspension quantity of insulator morely, have better economic and social effect.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment one;
Fig. 2 is the structural representation of execution mode two;
Among the figure, 1 is the gold utensil seat, and 2 is the gold utensil pull bar, and 3 is porcelain core, and 4 is overcoat, and 41 is last protection plate, and 42 are following protection plate.
Embodiment
Below in conjunction with description of drawings embodiment of the present utility model.
Execution mode one: with reference to Fig. 1.Compound suspended pot shaped insulator, has gold utensil seat 1, gold utensil pull bar 2, and the porcelain core 3 that bonds together by adhesive and gold utensil seat 1 and gold utensil pull bar 2, external packets at porcelain core 3 is covered with the overcoat made from silicon rubber 4, extend protection plate 41 on laterally at overcoat 4, extend a following protection plate 42 laterally at the overcoat 4 of the lower surface of last protection plate 41 near the upper surface of the porcelain core 3 of gold utensil seat 1.
Execution mode two: referring to Fig. 2.Be that with the different of execution mode one overcoat 4 that following protection plate 42 is porcelain core 3 sidewalls two extensions laterally promptly have two following protection plates 42.Middle following protection plate can be suitably littler.
