Problems solved by technology

[0005] The purpose of the present invention is to provide a lightning protection device for wind power generators, to solve the problem that the existing wind power lightning protection devices proposed in the background technology above generally use lightning balls because they are located at high places and are easily affected by strong winds. The structure realizes the guidance of lightning, but the area of ​​the lightning receiving ball is relatively small, and the lightning receiving effect is not good enough

Abstract

The invention discloses a lightning protection device for a wind generating set, and relates to the technical field of wind generating. The problems of small lightning receiving area and poor lightning receiving effect of an existing lightning protection device for wind generating are solved. The lightning protection device comprises a lightning protection device main body; a plurality of groups of lower swinging parts and a plurality of groups of upper swinging parts are arranged in a peripheral array and connected to the outer side of the lower part of the lightning protection device main body through hinges; a group of driving parts are fixedly connected into the lightning protection device main body; a group of stop block transmission parts are connected to the upper part of the innerpart of the lightning protection device main body in a driving mode; and a group of unfolding transmission parts are rotatably connected to the lower part of the inner part of the lightning protectiondevice main body. According to the lightning protection device, the conversion between a lightning receiving ball and a lightning receiving net is achieved, when the lightning is large, the lightningreceiving range is increased by unfolding the lightning receiving net, when not in use, the lightning receiving net is folded into a lightning receiving ball state, the influence of strong wind on the lightning protection device is prevented, the service life is prolonged, and the practicability of the lightning protection device is improved.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a lightning protection device for a wind power generating set. Background technique [0002] Wind power generation is a power generation method that converts the kinetic energy of wind into electrical energy. Wind power generation is widely loved by people for its clean and non-polluting characteristics. In wind power generation, generators are often used for power generation. Because generators are generally large in size and high in height It is relatively high and is vulnerable to lightning attacks during use, so it is necessary to install lightning protection devices to prevent lightning damage to the generator set. [0003] For example, application number: CN201611147730.X The present invention discloses a lightning protection system for wind power generation devices, including an electric field shielding box installed outside the wind turbine unit, wherein the...
