Problems solved by technology

[0008] Although the above-mentioned patents all involve the lightning protection problem of wind turbines, there is no literature report on the lightning protection of the hub of the wind turbine. Even though the first patent mentions the "hub", read the literature carefully It is found that it cannot really solve the lightning protection problem of the hub of the wind turbine, so there is no improvement proposal specifically for the problems existing in the lightning protection system of the hub of the wind turbine, so it is necessary to improve this

Embodiment 1

[0045] A wind turbine hub lightning guiding wire system, comprising a blade root lightning receiving base 2, a blade end mounting plate 4, fixing bolts 3, a hub bracket 9, a lightning guiding wire 5 and a clamp 6; wherein, the blade root lightning receiving The base 2 is fixed on the manhole cover plate 1 at the blade end by fixing bolts; the cross section of the blade end mounting plate 4 is "L" shape, which is convenient to improve the strength of the blade end mounting plate, and also facilitates the positioning of the lightning conductor 5 when it is installed. Rely on; the blade end mounting plate 4 is fixed on the blade root lightning receiving base 2 through the fastener 3, after the blade end mounting plate 4 is installed on the blade root lightning receiving base 2, then the blade root lightning receiving base 2 is connected to the blade Manhole cover plate 1 at the end, and ensure that there should be a gap of 1-500mm between the lower end surface of the blade end mou...

Embodiment 2

[0054] The principle of the second embodiment is the same as that of the first embodiment, so the following only briefly introduces this embodiment. A wind turbine hub lightning conductor system, comprising a blade root lightning terminal base 202, a blade end mounting plate 204, fixing bolts 203, a hub bracket 209, a lightning conductor 205 and a clamp 206; wherein, the blade root lightning terminal The base 202 is fixed on the blade end manhole cover plate 201 through fixing bolts; one end of the lightning guiding wire 205 is fixed on the blade end mounting plate 204 through a clamp 206, and the other end of the lightning guiding wire 205 is fixed on the hub through a hub wire clamp 208 On the bracket 209, there is a closing opening at the lower end of the blade end mounting plate 204 to form a groove. When the lightning conductor 205 passes through the closing, it is further bound to the lower end surface part of the blade end mounting plate 204 through a cable tie 207 to fo...

Abstract

The invention provides a fan hub lightning guiding wire connecting method and a lighting guiding system. The fan hub lightning guiding wire connecting method is characterized in that a fan hub lightning guiding wire is divided into two parts, one part is a lightning guiding wire connection installation plate which is of a rigid structure, the other part is a soft lightning guiding wire which is of a soft structure, the lightning guiding wire connection installation plate and the soft lightning guiding wire form the semi-rigid composite type fan hub lightning guiding wire in a combined mode, the semi-rigid composite type fan hub lightning guiding wire is respectively installed on a manhole plate of the blade end and a hub support, and therefore fan hub lightning guiding wire system is formed.

Description

Technical field [0001] The present invention relates to a fan protection method and device, in particular to a fixed connection method and system device for the lightning guide wire of the fan hub, which is mainly suitable for guiding the lightning current of the fan blade to the hub, and then passing the lightning current through the hub and other channels. The current is directed to the earth, thus preventing damage to the pitch bearings due to lightning currents. Background technique [0002] Since wind turbines are generally located in relatively open or high geographical locations, they are extremely vulnerable to lightning strikes. Therefore, corresponding lightning protection measures will be taken in wind turbines to prevent lightning strikes. The lightning protection system of the hub of the wind turbine is a part of it; in the existing lightning protection system of the hub of the wind turbine, it is necessary to use a lightning conductor fixed between the end of t...
