Abstract
The utility model relates to the technical field of high-voltage bushings and is specifically applied to a high-voltage bushing guiding one or a plurality of high-voltage conductors to pass through a baffle, insulating the conductors from the baffle and playing the role of supporting. The high-voltage bushing is mainly composed of a high-voltage connector, an insulator and a flange, wherein the insulator and the flange are connected through thread screwing and are sealed and fixed with resin. The metal end faces of one end, connected with the insulator, of the flange are respectively provided with a spigot, which makes the tangent plane of the insulator lower than the metal faces of the flange. Therefore, the air gap between the tangent plane of the insulator and the metal faces of the flange is reduced, the appearance of tips is greatly reduced, the occurrence of flashover and breakdown phenomena is effectively reduced, the local discharge level is improved, safe and reliable operation of the high-voltage bushing can be ensured, and the insulating properties of products can be ensured to meet the requirements of the national standard.
Description
Technical field
The utility model relates to the assembly structure of a kind of bushing insulator and flange body, specifically is applied to guide one or several high-pressure conductors to make in conductor and barrier insulation and the passive bushing by dividing plate, belongs to the bushing technical field.
Background technology
Bushing is used for one of guiding or several high-pressure conductors pass through dividing plate (for example wall or case shell), plays insulation and supporting role.Existing bushing insulator is connected with flange body and is screwed connection by screw thread, the tangent plane of insulator is higher than the flange body end face, there is larger air gap between insulator and the flange body, easily taper off to a point, bushing is difficult to by the various types test, and insulation level does not reach the requirement of national standard.
Summary of the invention
The deficiency that exists in order to solve prior art, the utility model provide a kind of rational in infrastructure, bushing insulator of good insulation preformance and the assembling of flange body.
The assembly structure of a kind of bushing insulator of the utility model and flange body mainly is comprised of high pressure connector, insulator and flange body.Described insulator is the insulating cylinder that is formed by poured with epoxy resin, and described insulator is connected an end car with flange body have screw thread.Described flange body is metal material, and described flange body is connected an end car with insulator have screw thread, and is provided with a seam at the threaded metal end face of car.Described seam makes the tangent plane of insulator be lower than the metal end face of flange body, reduced the air gap between insulator and the flange body, greatly reduced most advanced and sophisticated appearance, make bushing in power-frequency withstand voltage test, lightning impulse withstand voltage test and partial discharge test, reduce the generation of flashover and punch-through, improve local discharging level.
The assembly structure of a kind of bushing insulator of the utility model and flange body, effectively put forward the dielectric strength of bushing, guaranteed that the insulation property of product meet the requirement of national standard, made product safe and reliable in running, greatly improved the qualification rate of product.
