A double-head grounding arrester base

Abstract

A base of a double-headed grounding arrester includes a fixed base, an insulating base detachably connected to the fixed base, and a mounting base detachably connected to the insulating base. The spiral groove on the side wall of the through hole, the threaded through hole on the three corners of the upper surface of the installation base, the cylindrical transfer cavity inside the installation base, and the transfer slot in the middle of the side wall of the transfer cavity , the transfer disc connected to the transfer groove, the ten transfer cones connected to the side of the transfer disc, the inner space set in the transfer cone, the plurality of transfer balls arranged in the inner space, the fixed connection The transfer rod on the transfer ball, the first ground groove set on the side wall of the installation base, the first ground rod fixedly connected to the adapter plate, the second ground groove set on the side wall of the mount, and the fixed connection Second ground rod on adapter plate.

Description

technical field [0001] The invention relates to the technical field of lightning arresters, in particular to a double-headed grounding lightning arrester base. Background technique [0002] Due to its working principle, the arrester must be installed insulated from the power facilities. The insulating arrester base in the prior art has a metal disc-shaped base body, which is fixed by three bolt structures, because the bolts are also made of metal. Therefore, in the process of installation, an insulating sleeve needs to be installed outside the bolt, and an insulating block is respectively arranged at the screw head and the nut outside each insulating sleeve, and the gasket is sandwiched between the two insulating blocks. Base body to ensure insulation effect. This kind of lightning arrester base has many parts, the production and assembly costs are high, and because the structure is relatively complex, the requirements for installation precision control are also high, not o...

AI Technical Summary

Problems solved by technology

This kind of lightning arrester base has many parts, the production and assembly costs are high, and because the structure is relatively complex, the requirements for installation precision control are also high, not only the workload is large, the operation is extremely inconvenient, and this installation method is It was carried out at high altitude, and the lightning arrester was damaged after the thunderstorm. The staff inspected the line and increased the work intensity and pressure of the staff during the process of replacing the lightning arrester.
