Embodiment 1

[0044] Such as Figure 2-4 As shown, a new trapezoidal arc-extinguishing insulator is mainly composed of an insulator body 1, a low-voltage electrode 2 and a high-voltage electrode 3. The lower end of the insulator body 1 is open, the interior is hollow, and several insulating partitions are arranged along the longitudinal direction of the insulator body 1. The plate 4 makes the insulator body 1 form several independent recoil perfusion arc extinguishing cavities 5. In each recoil perfusion arc extinguishing cavity 5, a recoil device 6 is placed, and the recoil device 6 is present inside the insulator body 1. Spiral ladder arrangement; wall electrodes 7 are provided on the insulating partitions 4 between two adjacent recoil devices 6, and the top of the recoil device 6 underneath is connected with the wall electrode 7 on the upper side The bottom of the recoil device 6 is connected to the other side of the wall electrode 7, so that the recoil device 6 is connected end to end in...

Embodiment 2

[0050] The difference between this embodiment and the first embodiment is that: the outer surface of the insulator body 1 is provided with a plurality of skirts 8.

Embodiment 3

[0052] The difference between this embodiment and Embodiment 1 is that the wall electrode 7 uses a compression arc extinguishing tube.

Abstract

The invention discloses a novel trapezoidal arc extinguishing insulator, which is mainly composed of an insulator main body, a low-voltage electrode and a high-voltage electrode, wherein the insulatormain body is hollow, a plurality of insulating partition plates are arranged in the longitudinal direction of the insulator main body to form a plurality of independent backflushing perfusion arc extinguishing cavities in the insulator main body, a backflushing device is arranged in each backflushing perfusion arc extinguishing cavity, the backflushing devices are arranged in the insulator main body in a spiral stepped arrangement manner, a wall electrode is arranged on the insulating partition plate between every two adjacent backflushing devices, the top of the backflushing device located on the lower portion is connected with one face of the wall electrode, and the bottom of the backflushing device located on the upper portion is connected with the other face of the wall electrode, sothat the backflushing devices are sequentially connected together end to end. According to the invention, the novel trapezoidal arc extinguishing insulator can effectively prevent the flashover problem of the lightning protection device, reduces the lightning trip-out rate of power equipment, protects power facilities, improves the reliability of a power grid, and facilitates the safe production of power.

Description

Technical field [0001] The invention belongs to insulators used for overhead lines of power transmission and distribution, and relates to a novel trapezoidal arc extinguishing insulator. Background technique [0002] Insulators are a special insulation control that can play an important role in overhead transmission lines. In the early years, insulators were mostly used for telegraph poles, and slowly developed a lot of disk-shaped insulators hung on one end of the high-voltage wire connection tower. It is used to increase the creepage distance and is usually made of glass or ceramic. Insulators should not fail due to various electromechanical stresses caused by changes in the environment and electrical load conditions, otherwise the insulators will not have a significant effect and will damage the use and operating life of the entire line. [0003] The main function of insulators is to achieve electrical insulation and mechanical fixation, for which various electrical and mechani...
