Abstract
The utility model discloses a wind driven generator, in particular to a lightning stroke recording device for a blade of a megawatt-grade wind driven generator, which is structurally characterized in that the front end of the blade is provided with a blade tip lightning arrester (6), and the rear end thereof is provided with a blade root flange (7); a lightning stroke electric conduction system (1) is arranged between the blade tip lightning arrester (6) and the blade root flange (7); and the lightning stroke electric conduction system (1) is provided with a blade lightning stroke recording card (2). In the utility model, through reading the lightning stroke recording data of the blade lightning stroke recording card, the halt inspecting time of a wind driven generator set is shortened, the inspecting cost is reduced and the lightning stroke damage inspecting accuracy of the blade is improved, and thereby, an accurate data basis is provided for analysis on solving and preventing the blade from lightning strokes.
Description
Technical field
The utility model relates to wind-driven generator, relates in particular to a kind of thunderbolt recording device that is used for blade of MW class wind turbine.
Background technique
Thunderbolt at present is the principal element that blade of wind-driven generator damages, especially for the MW class wind turbine group.According to statistics, per 100 wind energy conversion systems, lightning fault was nearly 14 times in 1 year.7% to 10% blade damages relevant with lightning fault.But because the cost of overhaul, it is very difficult that the cause analysis of the blade damage of being struck by lightning becomes, and also is unfavorable for solving the anti-lightning strike technical barrier of blade.Therefore the inspection method of simplifying blade of wind-driven generator thunderbolt damage is put forward higher requirement.
The model utility content
For solving the problems of the technologies described above, the utility model provides a kind of blade of wind-driven generator thunderbolt recording device, whether purpose is to check that conveniently blade suffers the thunderbolt situation by reading the thunderbolt record data of blade thunderbolt record chart, suffer damage so that judge blade.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of blade of wind-driven generator thunderbolt recording device, its structure is as follows: the front end at blade is provided with the blade tip arrester, the rear end of blade is the blade root flange, is provided with the thunderbolt conducting system between blade tip arrester and blade root flange, and blade thunderbolt record chart is installed on the thunderbolt conducting system.
Described blade thunderbolt record chart inserts fixedly in the cutting ferrule, and fixedly cutting ferrule is installed on the blade root transition piece, and the blade root transition piece is connected with the conducting system that is struck by lightning by bolt.
Described blade thunderbolt record chart inserts fixedly in the cutting ferrule, fixes by the fixing pinning of cutting ferrule downside.
Owing to adopt technique scheme, make to the utlity model has following advantage and effect:
By reading the thunderbolt record data of blade thunderbolt record chart; shortened the time of wind power generating set shutdown inspection; reduced the inspection cost, improved the blade thunderbolt and damaged the accuracy of checking, solved and avoid blade to suffer thunderbolt that the accurate data foundation is provided for analyzing.
Description of drawings
Fig. 1 is a schematic representation of the present utility model.
Fig. 2 is the local structure for amplifying schematic representation of A among Fig. 1.
Among the figure: 1, thunderbolt conducting system; 2, thunderbolt record chart; 3, fixing cutting ferrule; 4, blade root transition piece; 5, bolt; 6, blade tip arrester; 7, blade root flange; 8, pinning.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the utility model blade of wind-driven generator thunderbolt recording device, its structure is as follows: the front end at blade is provided with blade tip arrester 6, the rear end of blade is a blade root flange 7, between blade tip arrester 6 and blade root flange 7, be provided with thunderbolt conducting system 1, blade thunderbolt record chart 2 is installed on the thunderbolt conducting system 1.Blade thunderbolt record chart 2 inserts fixedly in the cutting ferrule 3, and fixedly cutting ferrule 3 is installed on the blade root transition piece 4, and blade root transition piece 4 passes through bolt 5 and is connected with the conducting system 1 that is struck by lightning.
Above-mentioned blade thunderbolt record chart 2 inserts fixedly in the cutting ferrule 3, fixes by the fixing pinning 8 of cutting ferrule 3 downsides.
When the blade arrester is struck by lightning, the magnetic stripe data on the blade thunderbolt record chart 2 is with deleted, and therefore, the large-scale thunder-strike current of thunder and lightning always is recorded on the blade thunderbolt record chart.
Claims (3)
1. blade of wind-driven generator thunderbolt recording device, it is characterized in that structure is as follows: the front end at blade is provided with blade tip arrester (6), the rear end of blade is blade root flange (7), between blade tip arrester (6) and blade root flange (7), be provided with thunderbolt conducting system (1), blade thunderbolt record chart (2) is installed on the thunderbolt conducting system (1).
2. blade of wind-driven generator thunderbolt recording device according to claim 1, it is characterized in that described blade thunderbolt record chart (2) inserts fixedly in the cutting ferrule (3), fixedly cutting ferrule (3) is installed on the blade root transition piece (4), and blade root transition piece (4) is connected with thunderbolt conducting system (1) by bolt (5).
3. blade of wind-driven generator according to claim 2 thunderbolt recording device is characterized in that described blade thunderbolt record chart (2) inserts fixedly in the cutting ferrule (3), fixes by the fixing pinning (8) of cutting ferrule (3) downside.
