Description

The blade lightning protection device of offshore wind turbine
[technical field]
The present invention relates to the blade lightning protection device of offshore wind turbine.
[background technique]
In view of sea climate environment has huge difference with land, thunderstorm activity is more frequent, lightning strike accident district occurred frequently, in order to improve aerogenerator unit safe, reduce the possibility of lightning strike accident, avoid unnecessary loss, improve unit anti-lightning ability, invented a kind of novel offshore wind farm turbines vane lightning protection conducting unit.
On the blade of the land wind-driven generator of tradition, be generally all provided with lighting protection device, and lighting protection device on existing blade is generally to have a lightning protection ring on blade, when thunder and lightning hits blade arrester, lightning current is delivered to lightning protection ring, through lightning protection brush, earth cable, guide on wheel hub lighting protection device, so far complete the earial drainage of thunder and lightning on blade, realize the conduction of lightning current.
Because root of blade lightning protection ring diameter is bigger than normal, be oval, cannot make carbon brush surface stressed evenly.Traditional method is that lightning protection brush is slided on blade shell at present, in vane propeller-changing process, because the problems such as discontinuity and centrifugal force cause very large impact to lightning protection brush, cause lightning protection brush to come off, make lightning protection brush short working life, need to often change, affect marine unit safety.
[summary of the invention]
The object of the invention is to overcome the deficiencies in the prior art part, provide a kind of simple in structure, lightning protection effect is good, easy for installation, carbon brush can not come off, carbon brush long service life, do not need frequent replacing, can not affect the offshore wind farm turbines vane lighting protection device of marine unit safety.
