Abstract

A distribution network line lightning protection device disclosed by the present invention comprises an electrician box, a mounting support page is fixedly arranged at the bottom of the outer side of the electrician box, a protector base is arranged at the top of the mounting support page, a lightning protection protector is fixedly arranged at the top of one end of the protector base, and a mounting threaded column is fixedly arranged in the middle of the mounting support page. A stud hole is fixedly formed in the middle of the protector base, and the mounting threaded column is connected with the stud hole in a sleeved mode. A fixing shaft is fixedly arranged in the electrician box, a rotating support plate is movably arranged on the surface of the fixing shaft, a limiting groove is fixedly formed in the surface of the rotating support plate, the limiting groove is matched with the mounting threaded column, and a locking nut is arranged at the top of the rotating support plate and is in threaded connection with the mounting threaded column. The device is suitable for different types of towers, the power supply reliability is improved, the labor intensity of constructors is reduced, and the working safety of the constructors is improved.

Description

technical field [0001] The invention relates to the technical field of line lightning protection, in particular to a lightning protection device for distribution network lines. Background technique [0002] With the increase of distribution network lines, the safety of the lines cannot be ignored. The lightning overvoltage amplitude of 10kV overhead distribution line is high and the discharge time is short, but the insulation level of 10kV distribution line is low. In the absence of lightning protection devices, lightning overvoltage may occur, causing flashover of insulators. The power-frequency freewheeling current is formed on the lightning flashover channel to blow the wire, so the role of the lightning protection device is particularly important. [0003] However, the current lightning protection device is affected by the installation structure, the fixed installation is relatively complicated, and the disassembly process is cumbersome, and it is only suitable for the ...
