Multifunctional anti-thunder porcelain insulator with safety cover and rain and snow prevention electricity testing ground ring

Abstract

The invention discloses a multifunctional anti-thunder porcelain insulator with a safety cover and a rain and snow prevention electricity testing ground ring. The multifunctional anti-thunder porcelain insulator comprises a porcelain insulator with a rainproof plate, wherein a metal end is arranged at the upper end of the porcelain insulator, a wiring clamp is arranged at the top end of the metalend, and one end of the wiring clamp is connected to an electricity testing ground ring through a connecting arm; one side of the metal end is connected to a lightning protection rod which is downwards bent, a discharge end facing the lower end of the insulator is arranged at the lower end of the lightning protection rod, and a discharge head which is opposite to the discharge end of the lightningprotection rod is arranged at the lower part of the porcelain insulator; the metal end, the wiring clamp, a connecting arm of the electricity testing ground ring and the root of the lightning protection rod are all installed in the safety cover. A waterproof mechanism is arranged on the exposed metal edge of the electricity testing ground ring. The multifunctional anti-thunder porcelain insulatorhas the advantages that only one waterproof cover capable of rotating is installed on one exposed side of the electricity testing ground ring, and the waterproof cover can be freely rotated to the top according to needs, so that a waterproof effect is guaranteed; and furthermore, the electricity testing ground ring is biased, so that the operation of a grounding hook is facilitated.

Description

technical field [0001] The invention relates to a multi-functional lightning protection porcelain bottle insulator with a safety cover and a rain and snow proof electric test grounding ring, which is used for supporting power transmission lines. Background technique [0002] Porcelain insulators are commonly used support components for power transmission lines. The prior art is a porcelain insulator with a safety cover and an electrical inspection grounding ring proposed by the inventor of the present application, including a porcelain insulator with a rainproof plate. The upper and lower ends are respectively provided with metal ends, and the axis of the metal end at the lower end is provided with a metal screw and a fixed nut; a terminal clamp is provided on the top of the metal end of the upper end of the porcelain insulator, and a connecting arm is connected to an electric test grounding ring on the terminal clamp. Connection; the metal end and the terminal clamp at the ...
