Gap lightning protection device based on electromagnetic transformation

Abstract

The invention discloses a gap lightning protection device based on electromagnetic transformation. The device comprises a cable, a bottom mechanism, a first fixing mechanism, a first connecting block,a wiring ball, a telescopic mechanism, a position adjusting mechanism, a first auxiliary ball, a second fixing mechanism, a second auxiliary ball and an insulator. The cable is fixedly connected withthe top end of a second fixing mechanism, the bottom of the second fixing mechanism is fixedly connected with the top of the insulator, and the bottom of the insulator is fixedly connected with the left top of the first auxiliary ball. According to the gap lightning protection device based on electromagnetic transformation, a clamping block, a clamping strip and a fixing strip are arranged; whenthe device is fixed on the cable, the cable is wrapped by a first semi-ring and a second semi-ring, the clamping block is clamped in a clamping groove, the first semi-ring and the second semi-ring arefixed to the cable through the fixing strip, the first semi-ring and the second semi-ring can be further fixed to the cable through a steel wires through arranged fixing thorns, and therefore the device can be fixed to the cable in a time-saving and labor-saving mode.

Description

technical field [0001] The invention relates to the technical field of gap lightning protection, in particular to a gap lightning protection device based on electromagnetic transformation. Background technique [0002] The discharge gap, also known as the protection gap, is generally composed of two metal rods exposed to the air separated by a certain gap, one of which is connected to the power phase line L1 or neutral line (N) of the required protection equipment, and the other A metal rod is connected to the ground wire (PE). When the instantaneous overvoltage strikes, the gap is broken down, and a part of the overvoltage charge is introduced into the ground, which avoids the voltage rise on the protected equipment. The distance between the two metal rods of this discharge gap can be adjusted as required, and the structure is relatively simple. The disadvantage is that the arc extinguishing performance is poor. The improved discharge gap is an angular gap, and its arc ext...

Problems solved by technology

[0003] The existing gap lightning protection device is inconvenient to install, and it takes time and effort to fix it by bolts. At the same time, the protection gap cannot be adjusted according to the actual situation, and the net arc cannot be effectively eliminated.
