Description
Technical Field
The utility model relates to a lightning protection device, concretely relates to insulator lightning protection set composite.
Background
The 10kV distribution network line is a main distribution network in China, and the network mainly bears the task of directly providing power for users. Because the network structure is complex, the insulation level of the line is low, the operation maintenance level of the line has a larger difference with the transmission line, the distribution network is easy to suffer from lightning accidents, and insulator flashover, disconnection or tripping accidents are caused, so that the national economy and the life of people are damaged.
In addition, the existing 10kV distribution network line lightning arrester is respectively communicated with a line and the ground through a lead and a grounding down lead, after the lightning arrester in operation acts, lightning current enters the ground through the upper and lower connecting leads of the lightning arrester, and because the upper and lower leads of the lightning arrester have inductance (the inductance of a 1m connecting wire is close to about 1 muH), under the condition of medium lightning, the voltage drop on the connecting wire reaches dozens of kilovolts, and the residual voltage of the lightning arrester is added, the lightning arrester is easily damaged or is subjected to insulation breakdown by protection equipment.
Disclosure of Invention
