Lightning protection device for power distribution lines

Abstract

The invention relates to the technical field of electric power distribution, in particular to a lightning protection device for electric power distribution lines, which includes a cabinet body, a lightning detector, a single-phase input wire, a single-phase output wire, a support plate is provided inside the cabinet body, and the support plate The two sides away from each other are fixedly connected to the inner side of the cabinet body. There are two through holes on one side of the support plate. The inner sides of the through holes are fixed with insulating sleeves. The inner sides of the insulating sleeves are fixed with conductive blocks. The lightning detector is fixedly connected Inside the cabinet, one end of the single-phase input wire is electrically connected to the lightning detector, and one side of the lightning detector is electrically connected to a connecting wire. In the present invention, by setting a lightning detector, a support plate, an insulating sleeve, a conductive block, a connecting wire, an insulating block, a conductive plate, an electric telescopic rod, a control processor, an anti-falling device, and an anti-power-off device, it has automatic lightning protection , Automatic circuit breaking, anti-dropping, anti-power failure, anti-short circuit and other functions.

Description

Technical field [0001] The present invention relates to the field of power distribution technology, in particular to a lightning protection device for power distribution lines. Background [0002] Electricity is based on electric energy as the power of energy, distribution is in the power system directly connected to the user and distribute electrical energy to the user link, the distribution system by the distribution substation, high-voltage distribution line, distribution transformer, low-voltage distribution line and the corresponding control and protection equipment composition, the existing technology for the distribution cabinet and power equipment power supply, most of them through the household line outside the anti-lightning leakage protector way to carry out lightning protection, and lightning leakage protector in the encounter with lightning, will automatically cut off the circuit, thereby causing power failure, no anti-blackout function , and lightning leakage prote...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem in the prior art that when power distribution cabinets and electric equipment are powered in the prior art, lightning protection is mostly performed by connecting the incoming line with a lightning protection leakage protector, and the lightning protection leakage protector When encountering lightning, it will automatically cut off the circuit, which will cause a power outage. It has no anti-power outage function, and the lightning protection leakage protector is not suitable for transmitting single-phase high-voltage power, so it cannot be applied to large-scale power equipment.
