Abstract
The utility model discloses a disconnector-containing type compound insulated column-type lightning-protection insulator. A rod body of an insulator body is peripherally covered by silicone rubber. The lightning-protection insulator has high bending-resistance performance and has a maximum bending tolerance load of 4.0kN. The material of silicone rubber is adopted as external insulation, so that the insulator has excellent external insulation performance and a strong anti pollution capability; and large creep distance is adopted, so that the insulator can be used in any dirty region and plateau region. By means of the insulator, the lightning withstand level of a line is improved, the lightning trip-out rate is reduced, and when the line is suffered from lightning stroke, the insulator is conducted to discharge lightning current energy; and installation is convenient. The insulator is applied only by replacing an original porcelain insulator and is small in size and light in weight. When the lightning protection function of the insulator is failed, a disconnector can effectively fall off, the normal operation of the line is not influenced, indication is obvious, and fault points can be discovered conveniently.
Description
Technical field
The utility model belongs to the insulator field, relates in particular to a kind of band and breaks away from type compound inslation pillar anti-thunder insulator.
Background technology
Insulator is the important component part of transmission line, and its rational Application plays decisive role to the safe operation of transmission line.Along with the development of ultra-high/extra-high voltage large capacity transmission technology, porcelain or glass insulator that traditional transmission line uses, heavy frangible, intensity is low, and pollution flashover accident easily occurs, and the cleaning maintenance workload is large, does not also obtain ideal effect.
The utility model content
The purpose of this utility model is to provide a kind of band to break away from type compound inslation pillar anti-thunder insulator.The porcelain or the glass insulator that use in order to solve present traditional transmission line, heavy frangible, intensity is low, and pollution flashover accident easily occurs, the large problem of cleaning maintenance workload.
The utility model is achieved in that a kind of band breaks away from type compound inslation pillar anti-thunder insulator, covers silicon rubber around the body of rod of this device insulator body.
Further, the resistor disc of this insulator is linked to be an integral body.
Further, this anti-thunder insulator adopts the composite insulator body that forms pottery and insulating material around resistor disc.
The band that the utility model provides breaks away from type compound inslation pillar anti-thunder insulator, is mainly used in transmission line.The present invention has high anti-bending strength, and the bending tolerance load of similar porcelain insulator is 1.4,2.0,3.0,3.5,4.0kN, and this product reaches maximum deflection tolerance load 4.0kN; Adopt silastic material as external insulation, have excellent external insulation performance, stain resistance is strong, takes large distance, can be used for any filthy area and highlands; Improve the lightning withstand level of circuit, reduce tripping rate with lightning strike, when circuit is struck by lightning, insulator conducting, the lightning current energy of releasing; Easy for installation, this product is as long as change the reason porcelain insulator; Volume is little, lightweight, and after the lightning protection effect was lost efficacy, disconnector can effectively come off, and does not affect circuit and normally moves, and indication obviously is convenient to find the fault point.
