A Protection Mechanism for Protecting the Shed of Electric Porcelain Lightning Arrester

Abstract

The invention discloses a protection mechanism for protecting an umbrella skirt of an electric porcelain arrester. The protection mechanism comprises a truncated cone-shaped inner frame and a rectangular outer frame, wherein an upper ring frame of the truncated cone-shaped inner frame is connected with corner angles on the rectangular outer frame through support rods; a lower ring frame of the truncated cone-shaped inner frame is fixedly arranged on lower edge bars of the rectangular outer frame through flange seats; the upper ring frame is connected with the lower ring frame through ring rods; the inner side of the upper ring frame is connected with semi-circular arc frame plates through telescopic poles; the middles of the ring rods are connected with an umbrella skirt protection ring plate through clamping plate seats; hoisting ring frames are arranged on middle edge bars on the left side surface and the right side surface of the rectangular outer frame; support corner brackets arearranged at four corners of a bottom frame plate of the rectangular outer frame; a fixed bottom plate is arranged at the bottom of each support corner bracket; a fixed bolt is arranged in a threaded hole in each fixed bottom plate; and a bird-repellent ribbon is arranged on the outer surface of the rectangular outer frame, so that collision of the outside world and the umbrella skirt can be reduced.

Description

technical field [0001] The invention relates to the technical field of lightning arresters, in particular to a protection mechanism for protecting the sheds of electric porcelain lightning arresters. Background technique [0002] In modern buildings, the arrester is a common device, and it is also called a voltage limiter, which is a device that can release overvoltage energy and limit the magnitude of overvoltage. When the overvoltage occurs, the voltage between the two terminals of the arrester does not exceed the specified value, so that the electrical equipment will not be damaged by the overvoltage; after the overvoltage acts, the system can quickly return to normal state; the arrester is to protect the electrical equipment from atmospheric overvoltage Electrical appliances; lightning arresters are equipment used to protect equipment in substations from lightning shock waves. When the lightning shock wave introduced into the substation along the line exceeds the protec...
