A Multi-lobe Grounding System for Lightning Arrester

Abstract

The invention discloses a multi-lobed grounding system for a lightning arrester, which comprises a cylindrical rod body composed of a plurality of petal rods. Two adjacent petal rods are welded by two kinds of metals. At least one cylindrical inner tube is fixed inside the rod body, and the upper and lower ends of the inner tube are fixedly connected with a plurality of hard outer tubes, and the plurality of outer tubes are distributed around the rod body along the circumference. The outer tube is fixedly connected with multiple sets of annular scrapers, the inner wall of the scraper is against the outer wall of the rod, and each inner tube is correspondingly provided with a driving assembly, a braking assembly and a first impeller. The advantage is that multiple sets of inner tube structures can be provided in this application, and the distance between the first impeller and the second impeller in different inner tubes is different, which can control the timing of the water hammer effect in different inner tubes, thereby ensuring that the device of this application can Scrape off the oxide on the outer wall of the valve rod completely to complete the self-maintenance effect.

Description

technical field [0001] The invention relates to the technical field of power facilities, in particular to a multi-lobed grounding system for a lightning arrester. Background technique [0002] In thunderstorm weather, the charged cloud layer above the tall buildings makes the tip of the conductor accumulate a large amount of charge under the action of electrostatic induction. When there are more charges on the cloud layer, the air between the arrester and the cloud layer is easily broken down and becomes a conductor. Like this, charged cloud layer and arrester form path, and arrester is a ground connection, and arrester just can be led people's the earth to the electric charge on the cloud layer, and it is dangerous that it is not constituted skyscraper itself, has guaranteed its safety.

Problems solved by technology

[0003] In real life, the lightning arrester is often grounded simply through a metal rod buried in the ground, but the complex underground environment makes the surface of the metal ground rod easy to oxidize, and the resistance of the oxidized ground rod increases, and the performance of the wire decreases, that is, it cannot Timely and large amounts of charge are poured into the ground, which is prone to danger. At this stage, the maintenance of ground rods is more manual maintenance, which is time-consuming and laborious, and it is difficult to detect the oxidation degree of the ground rod surface. Therefore, a self-maintainable arrester is designed. The multi-lobe grounding system is particularly important
