Lightning arrester for wind power generation

Abstract

The invention relates to the technical field of wind power generation, and discloses a lightning arrester for wind power generation. A wheel sticking rod is attached to the outer surface of a convex disc, a movable frame is movably connected to the right side of the wheel sticking rod, a piston plate is fixedly mounted at the tail end of the movable frame, and the piston plate is slidably mounted in a suction cylinder; the bottom of the suction barrel is fixedly connected to the top of the power generation bin and the interior of the sleeve barrel through hoses. After a bottom rod at the bottom of a sponge seat in a water storage barrel faces downwards and the surface of the bottom rod is in contact with a cambered surface block on the surface of a shaft sleeve barrel, the shaft sleeve barrel is driven to move towards a wheel shaft until the shaft sleeve barrel is sleeved on a semiconductor shaft in the wheel shaft, so that the temperature rise in the shaft sleeve barrel is transmitted to the semiconductor shaft; the internal conductivity of the semiconductor shaft is increased along with the rise of the temperature, so that the situation that after the lightning rod receives lightning, insulation is formed between the wheel shaft and the power generation bin through the semiconductor with the increased temperature can be effectively avoided, and current permeation is blocked through the combination of the lightning rod.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a lightning protection device for wind power generation. Background technique [0002] As the height of wind turbine towers continues to increase, the length of blades continues to increase, and the probability of wind turbines being struck by lightning also increases. The lightning protection of current wind power generation equipment is mainly to install lightning arresters on the blades, and set them inside the blades. Metal lead wire, connect the lead wire to the root of the blade, pass through the lightning protection interface connected to the hub, and then connect to the ground wire, and finally receive lightning through the lightning arrester. [0003] At present, on the outside of the wind turbine, when encountering strong winds, the lightning rod is likely to be blown off by the strong wind, resulting in economic losses. In thunderstorm weather, the blades...
