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. A lightning protection device for power distribution lines

The invention relates to the technical field of power distribution, in particular to a lightning protection device for a power distribution line, which comprises a cabinet body, a lightning detector,a single-phase input wire and a single-phase output wire, wherein a support plate is arranged on the inner side of the cabinet body, and two sides, far away from each other, of the support plate are fixedly connected to the inner side of the cabinet body; one side of the support plate is provided with two through holes; the inner side of each through hole is fixedly provided with an insulating sleeve, the inner side of each insulating sleeve is fixedly provided with a conductive block, the lightning detector is fixedly connected to the inner side of the cabinet body, one end of the single-phase input wire is electrically connected with the lightning detector, and one side of the lightning detector is electrically connected with a connecting wire. By arranging the lightning detector, the support plate, the insulating sleeve, the conductive block, the connecting wire, the insulating block, the conductive plate, the electric telescopic rod, the control processor, the anti-falling device and the anti-power-off device, the device has the functions of automatic lightning protection, automatic circuit breaking, falling prevention, power failure prevention, short circuit prevention and thelike.
Description
technical field [0001] The invention relates to the technical field of electric power distribution, in particular to a lightning protection device for electric power distribution lines. Background technique [0002] Electric power is powered by electric energy. Power distribution is a link in the power system that is directly connected to users and distributes electric energy to users. The power distribution system consists of power distribution substations, high-voltage distribution lines, distribution transformers, and low-voltage power distribution. Lines and corresponding control and protection equipment. In the prior art, when power distribution cabinets and power equipment are powered, lightning protection is mostly performed by connecting the lightning protection leakage protector externally to the incoming line, and the lightning protection leakage protector encounters When lightning strikes, it will automatically cut off the circuit, which will cause a power outage....
