Abstract

The invention discloses a semi-closed recoil comprehensive arc extinguishing insulator, which comprises an insulator main body arranged on a power transmission line overhead tower cross arm through aconnecting fitting, the interior of the insulator main body is hollow, an insulating partition plate is longitudinally arranged along the insulator main body so as to form two independent arc extinguishing cavities in the insulator main body, a recoil device is arranged in the upper end of the left arc extinguishing cavity, a recoil opening is formed in the lower end, an upper electrode is arranged at the top end of the recoil device, an airflow jetting device is arranged in the lower end of the arc extinguishing cavity on the right side, an airflow nozzle extending towards the outer side surface is formed in the upper end, a lower electrode is arranged at the bottom of the airflow jetting device, and a wall electrode is arranged on the insulating partition plate. The semi-closed recoil comprehensive arc extinguishing insulator can effectively prevent the flashover problem, reduces the lightning trip-out rate of power equipment, protects power facilities, improves the reliability of apower grid, and facilitates the safe production of power.

Description

technical field [0001] The invention belongs to insulators for power transmission and distribution overhead lines, and relates to a semi-closed recoil comprehensive 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 vario...
