Lightning protection porcelain insulator with lightning rod, and manufacturing process thereof

Abstract

The invention discloses a lightning protection porcelain insulator. The lightning protection porcelain insulator comprises a porcelain insulator body and a mounting frame, the inner side wall of the porcelain insulator body is rotatably connected with a rod body through a first bearing, the bottom of the rod body is rotatably connected with a fixing plate through a second bearing, and the outer side wall of the rod body is symmetrically and fixedly connected with four first fixing rods. Through the arrangement of the rod body, a third plate body and a lead, thunder and lightning above the rodbody can be led to the underground, the porcelain insulator is prevented from being damaged, and when the porcelain insulator shakes due to wind power or cable shaking, the porcelain insulator extrudes a second shell through a fixing plate, the second shell pushes a second spring through a third shell, a third supporting rod and a fourth supporting rod, the second spring can relieve pressure applied by the outside world, meanwhile, reverse thrust can be generated, and the fourth supporting rod is promoted to reset, so influences caused by vibration are reduced, and shaking between the bottom plate and the mounting frame is avoided.

Description

technical field [0001] The invention relates to the technical field of porcelain insulators, in particular to a lightning protection porcelain insulator provided with a lightning rod and a manufacturing process thereof. Background technique [0002] An insulator is a device for electrical insulation and mechanical fixation of electrical equipment or conductors at different potentials. Insulators with electric porcelain as insulators become porcelain insulators. An insulator is a special insulation control that plays an important role in overhead transmission lines. It is mainly used for the connection of wires and cables. For example, a lot of disc-shaped insulators are hung on one end of the high-voltage wire connection tower. It is to increase the creepage distance, and it is usually made of glass or ceramics. This is an insulator. [0003] However, the existing insulators are not equipped with lightning rods, which cannot better disperse lightning and are easy to damag...

AI Technical Summary

Problems solved by technology

[0003] However, the existing insulators are not equipped with lightning rods, which cannot better disperse lightning and are easy to damage the device, and the existing insulators lack shock-absorbing measures at the connection with the support, so that the connection will be exposed to wind and vibration for a long time. Looseness will affect the fixing effect, especially in the case of cable shaking, which will easily lead to loose connection. Therefore, a lightning-proof porcelain insulator with a lightning rod and its manufacturing process are proposed
