Abstract

The invention discloses a novel trapezoidal bipolar arc extinguishing insulator, which is mainly composed of an insulator main body, an upper electrode and a lower electrode, wherein the insulator main body is hollow and is provided with a plurality of insulating partition plates so as 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 spirally arranged in the insulator main body in a stepped manner, the backflushing openings of every two adjacent backflushing devices are opposite in direction, a wall electrode is arranged on the insulating partition plate between every two adjacent backflushing devices, the top of the lower backflushing device is connected with one face of the wall electrode, and the bottom of the upper backflushing device is connected with the other face of the wall electrode. According to the invention, the problem of flashover of the lightning protection device is effectively prevented, the lightning trip-out rate of power equipment is reduced, power facilities are protected, the reliability of a power grid is improved, and power safety production is facilitated.

Description

technical field [0001] The invention belongs to insulators used for power transmission and distribution overhead lines, and relates to a novel trapezoidal double-pole arc-extinguishing insulator. Background technique [0002] Insulators are special insulation controls that can play an important role in overhead transmission lines. Insulators were mostly used on utility poles in the early years, and gradually developed into high-voltage wire connection towers where many disc-shaped insulators were hung at one end. It was used to increase the creepage distance and was usually made of glass or ceramics. Insulators should not fail due to various electromechanical stresses caused by changes in the environment and electrical load conditions, otherwise the insulator will not play a significant role and will impair the service and operating life of the entire line. [0003] The main function of the insulator is to achieve electrical insulation and mechanical fixation, for which var...
