Description

Grid type lightning protection device for wind generating set blade
Technical field
The utility model relates to wind generator set blade, particularly a kind of grid type lightning protection device for wind generating set blade.
Background technique
At present, along with the development of wind power technology, grid type wind power generating set strides forward towards maximization, absorbs more energy, and the height of wheel hub increases, and the diameter of wind wheel increases, and thunderbolt is become in physical environment wind-powered electricity generation unit is had to destructive major influence factors.
The lightning protection of traditional wind power generator incorporated in power network group blade generally adopts point fixing on blade that mode that arrester connects sudden strain of a muscle by the metal of wire ground connection is installed and protects blade and exempt from thunderbolt.But this Lightning Protection connects sudden strain of a muscle weak effect, anti-lightning strike area is little, and after being struck by lightning, the discharge value deficiency of arrester heating, cable, causes occurring that blade bursts, the phenomenons such as cable breakage.Affect the normal operation of wind park, increased maintenance cost, wind power generating set large scale development, also causes traditional blade lightning protection to occur serious deficiency.
Model utility content
The purpose of this utility model is to provide a kind of grid type lightning protection device for wind generating set blade.
The purpose of this utility model is achieved through the following channels: a kind of grid type lightning protection device for wind generating set blade, it is to be radially embedded with respectively main connecing to dodge band and the auxiliary sudden strain of a muscle band that connects on the positive and negative surface of wind wheel blade, the master on same surface connects to dodge and is with and auxiliary connecing between sudden strain of a muscle band by being flush-mounted in the join on skew sudden strain of a muscle band connection on wind wheel blade surface, radially being embedded with respectively leading edge at the leading edge of wind wheel blade and trailing edge connects and dodges band and trailing edge and connect and dodge band, the air dynamic behaviour that does not affect blade itself with embedded design is dodged in netted connecing, and has strengthened on the contrary the structural strength of blade; Two masters on the positive and negative surface of wind wheel blade connect to dodge between band and connect by the female electrified wire that is positioned at wind wheel blade enclosure interior, and two of the described positive and negative surface of wind wheel blade are auxiliary to be connect and dodge band, leading edge and connect and dodge band and trailing edge and connect and dodge band and be connected with female electrified wire by wire.
As the further optimization of this programme, described female electrified wire has two, one by wire and leading edge connect dodge band is connected, another root by wire with two auxiliary connect dodge band and trailing edge connect sudden strain of a muscle be be connected.
As the further optimization of this programme, described female electrified wire is by blade metal flange, carbon brush and wheel hub ground connection.
As the further optimization of this programme, described master connect dodge band, auxiliary connecing dodged band, leading edge and connect and dodge band, trailing edge and connect and dodge band and join on skew and dodge band and make for aluminium foil alloy material.
As the further optimization of this programme, described master connect dodge band, auxiliary connecing dodged band, leading edge and connect and dodge band and trailing edge and connect and dodge band for reticular structure.
As the further optimization of this programme, wind wheel blade is positive main to be connect and dodges band and the auxiliary area that lays that dodges band that connects is less than wind wheel blade reverse side master and connects and dodge band and the auxiliary area that lays that dodges band that connects.
The utility model grid type lightning protection device for wind generating set blade, is connect and is dodged band and effectively increased and connect sudden strain of a muscle area by main and auxiliary, leading edge, trailing edge, thereby thunderbolt has been produced to protection effectively.The main sudden strain of a muscle band that connects is directly connected with female electrified wire, auxiliary, leading edge, trailing edge connect and dodge band and be connected with female electrified wire by electrified wire, then by blade metal flange, carbon brush and wheel hub ground connection have been strengthened the conducting efficiency of blade to thunder and lightning, thunder-strike current is imported more quickly underground by approach passage more, prevent that thunder and lightning from piling up the even destruction of unit of blade.Connect the Embedded method of sudden strain of a muscle band and connect, ensured the air dynamic behaviour of blade.
