Abstract
The utility model discloses a kind of wind power generating set lightning-protection blade, comprise blade body and be arranged on the arrester in blade body, described arrester is connected with the wire in blade body, described blade body is provided with conductive mesh, described conductive mesh is connected with arrester, the surface of described blade body is provided with nanometer layer, described conductive mesh is wire netting, described wire netting comprises multiple grid, described blade body is provided with temperature monitoring, described arrester is tray-type gas electric discharge lamp, described tray-type gas electric discharge lamp comprises disc-shaped foot and is arranged on two plate electrodes on disc-shaped foot.Arrester of the present utility model is arranged in blade shell, one-body molded with blade shell, easy for installation, reduce costs, in addition, blade arrester have employed tray-type gas electric discharge lamp, and the intensity of the lightning current being diverted to conductive layer is effectively reduced, also reduce again the instantaneous high-temperature that arrester is formed simultaneously, reduce thunderstruck possibility.
Description
Technical field
The utility model belongs to technical field of wind power generation, a kind of wind power generating set lightning-protection blade of special design.
Background technique
Along with the development of wind generating technology, megawatt-grade high-power wind power generating set is used by increasing wind energy turbine set developer.Tower height, the length of blade of wind power generating set increase along with the continuous increase of generated output, and wind power generating set is arranged on more spacious area or coastal, maritime environment usually, and unit belongs to again protruding object.According to thunder and lightning selectivity characteristic, i.e. " point discharge " effect, the probability that unit is struck by lightning in this type of area is higher.At present, most of wind energy turbine set of China is distributed in northeast, North China and the Northwest.In recent years, along with the maturation of wind generating technology and the increase of the market demand, increasing southern wind energy turbine set builds successively.And the Thunderstorm Weather of southern area obviously will more than northern area, and fan MANUFACTURER and Construction of Wind Power side bring great test.
Model utility content
The technical problems to be solved in the utility model is: existing wind power generating set is easily struck by lightning.
In order to solve the problems of the technologies described above, the utility model provides a kind of wind power generating set lightning-protection blade, comprise blade body and be arranged on the arrester in blade body, described arrester is connected with the wire in blade body, described blade body is provided with conductive mesh, described conductive mesh is connected with arrester, the surface of described blade body is provided with nanometer layer, described conductive mesh is wire netting, described wire netting comprises multiple grid, described blade body is provided with temperature monitoring, described arrester is tray-type gas electric discharge lamp, described tray-type gas electric discharge lamp comprises disc-shaped foot and is arranged on two plate electrodes on disc-shaped foot, described disc-shaped foot is connected with the wire in blade body.
Preferably, described electrode is fixedly connected on disc-shaped foot by nut.
Technique scheme tool has the following advantages: arrester of the present utility model is arranged in blade shell, one-body molded with blade shell, easy for installation, reduce costs, in addition, blade arrester have employed tray-type gas electric discharge lamp, and the intensity of the lightning current being diverted to conductive layer is effectively reduced, also reduce again the instantaneous high-temperature that arrester is formed simultaneously, reduce thunderstruck possibility.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the present utility model;

Wherein, 1: blade body, 2: arrester, 3: conductive mesh.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As illustrated in fig. 1 and 2, the arrester 2 that wind power generating set lightning-protection blade of the present utility model comprises blade body 1 and is arranged in blade body, described arrester 2 is connected with the wire in blade body 1, described blade body 1 is provided with conductive mesh 3, described conductive mesh 3 is connected with arrester, and the surface of described blade body 1 is provided with nanometer layer.Blade body 1 of the present utility model establishes nanometer layer, the effect of waterproof can be played, add working life.
Arrester 2 of the present utility model is connected with blade root metal flange by the wire being arranged in blade body 1 inner chamber; by wheel hub ground connection; and the outer surface of blade body 1 is fixed with conductive mesh 3, conductive mesh 3 is connected with arrester 2, conductive mesh 3 surface coverage matcoveredn.Described conductive mesh 3 is a kind of grids with specification spacing that one deck is made by metallic material, blade surface wraps up by this grid, in order to improve through-current capability and the heat dispersion of conductive mesh 3, the material of conductive mesh 3 is preferably Cu alloy material, in grid, the sealike colour of Cu alloy material is not less than 1mm, and described arrester 2 can be one or more pieces.Blade body 1 is by flange apparatus and Flange joint.
Described blade arrester 2 is tray-type gas electric discharge lamp, is arranged on disc-shaped foot forms by two plate electrodes, and disc-shaped foot is connected with the wire in blade body 1 inner chamber, and electrode is fixedly connected on disc-shaped foot by nut.Described blade body 1 is provided with temperature monitoring, when temperature is too high, can warning be sent, so that staff processes in time.This blade body 1 is provided with timer, alarm, recording anemometer.This alarm is connected with temperature monitoring, when temperature is higher than predetermined value, sends alarm signal.This alarm can be voice guard, can also be microwave alarm.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and replacement, these improve and replace and also should be considered as protection domain of the present utility model.
