[0021] The present invention provides a lightning protection built-in column type voltage limiter with a self-limiting structure, which has the following beneficial effects:

[0022] The built-in column voltage limiter for lightning protection with a self-limiting structure has a bird-repelling component. When the built-in column voltage limiter for lightning protection is in use, the hemispherical wind shield is blown and rotated by the wind, and the hemispherical wind shield drives the bird-repelling rod and the reflector to rotate through the connecting rod and the fixing ring. The colored mirror stickers on the outer wall of the hemispherical wind shield will reflect light of different colors under the sun, and the reflective mirror stickers and the reflector on the inner wall of the hemispherical wind shield can reflect light, thereby playing a role in repelling birds and preventing birds from landing on the built-in column voltage limiter for lightning protection.

[0023] The built-in lightning protection column type voltage limiter with a self-limiting structure has a fixing component. When the counter is connected to the built-in lightning protection column type voltage limiter component, the lower mounting hardware is sleeved in the U-shaped rod, and then the U-shaped rod is installed with the arc-starting plate. The inclined surface of the fixing block contacts the arc-starting plate, and the fixing block is squeezed and moved inward. When the fixing block passes through the circular hole on the arc-starting plate, the fixing block is ejected by the elastic force of the first spring, and the lower mounting hardware is clamped between the U-shaped rod and the arc-starting plate, which can improve the installation efficiency of the U-shaped rod, the arc-starting plate and the built-in lightning protection column type voltage limiter component, and improve the convenience of using the built-in lightning protection column type voltage limiter.

[0024] The built-in lightning protection column voltage limiter with a self-limiting structure is connected to a component. When the built-in lightning protection column voltage limiter component is installed on a fixing plate, the installation component is inserted into the connection component, and at the same time, a plurality of limiting rods on the fixing plate are inserted into the circular holes on the installation plate. This can improve the stability of the built-in lightning protection column voltage limiter component when installed on the fixing plate, and at the same time, the inclined rectangular hole of the installation tube can be aligned with the insertion rod, thereby improving the stability and convenience of the built-in lightning protection column voltage limiter component when installed on the fixing plate.

[0025] The built-in lightning protection column pressure limiter with a self-limiting structure is connected to a component and an installation component. When installing the built-in lightning protection column pressure limiter, the T-bar is pulled downward, the four-sided pyramid and four insertion rods are moved downward, and then the fixing tube is inserted into the installation tube. Then the T-bar is loosened, and the four-sided pyramid is driven by the elastic force of the second spring to move the four insertion rods upward and insert them into the corresponding inclined rectangular holes on the installation tube. The connection component and the installation component can be quickly installed, thereby improving the convenience of using the built-in lightning protection column pressure limiter.

[0026] The built-in lightning protection column voltage limiter with a self-limiting structure adjusts the gap between the discharge electrode and the grading ring through the built-in lightning protection column voltage limiter component, the bolt is adjusted, and the position of the second angle piece is adjusted, so as to achieve the purpose of adjusting the gap between the discharge electrode and the grading ring. When a lightning overvoltage occurs in the power line, if the zinc oxide resistor fails, or the lightning energy exceeds the bearing capacity of the voltage limiter, the power frequency current will flow through the gap between the grading ring and the discharge electrode. Under the combined action of the high temperature and large current of the power frequency arc, the paint layer on the surface of the grading ring changes from color to black, which can play a conspicuous warning role and solve the problem of difficulty in fault finding for line patrol personnel.

When the power line is struck by lightning and overvoltage occurs, the lightning wave releases the energy of the lightning to the earth through the metal wire fixing seat 101, the zinc oxide resistor 1012, the grading ring 105, and the discharge electrode 1011. When the zinc oxide resistor 1012 fails or the lightning energy exceeds the bearing capacity of the voltage limiter when struck by lightning, the power frequency current flows through the gap between the grading ring 105 and the discharge electrode 1011. Under the combined action of the high temperature and large current of the power frequency arc, the paint layer on the surface of the grading ring 105 changes from color to black.
