Although in sliding friction with a part during operation, the copper alloy wires with high wearing resistance are still intact and are free of maintenance. The conductive brush has high conductibility; the copper alloy wires comprise 32 bunches; each bunch includes 512 copper alloy wires; the number of the 512 copper alloy wires after being folded is 1024; and the total sectional area of the 1024 copper alloy wires is equal to that of a 95 square meter copper wire. Therefore, the quick passing of the lightning current is facilitated, the lightning strike probability of the equipment is reduced, and the safety of the equipment is increased.
Description
Technical field
The utility model relates to the equipment of conduction lightning current in the wind turbine generator lightning protection earthing system, specifically a kind of lightning protection conduction brush of wind turbine generator.
Background technology
On the lightning Protection Design of wind turbine generator, need to carry out the conduction of lightning current in relative rotation between two equipment, in order to avoid equipment is struck by lightning.Existing lightning protection measures is to adopt carbon brush or similar products like to be fixed therein on the equipment, transmits lightning current with another equipment in the mode of sliding friction.Because it is primary raw material that carbon brush adopts carbon, belongs to a kind of easy consumption element, will need often to change because of friction has not been had by mill at set intervals, both increase cost, caused the wasting of resources, make troubles for again the work of wind turbine generator.And the carbon dust that carbon brush grinds off also can pollute unit, is unfavorable for the regular maintenance of unit.
The utility model content
In order to solve the problem that above-mentioned employing carbon brush carries out lightning protection and need often to change, the purpose of this utility model is to provide a kind of lightning protection conduction brush of wind turbine generator.
The purpose of this utility model is achieved through the following technical solutions:
The utility model comprises metal derby and copper alloy silk, and wherein metal derby is evenly equipped with a plurality of copper wires towards the surface of rotating part and is pressed into the hole, and each copper wire is pressed into and is equipped with the copper alloy silk in the hole.
Wherein: described metal derby is an aluminium block; Have through hole on the metal derby; Described copper alloy silk is 32 bundles, and every bundle is 512, is pressed into after the doubling in the metal derby, and the copper alloy silk after the doubling is 1024.
Advantage of the present utility model and good effect are:
1. copper alloy silk of the present utility model has high-wearing feature, and is still excellent although work with the parts sliding friction, has non-maintaining advantage.
2. the utlity model has high conductivity, 32 bundles, 512 of every bundles are folded in half into 1024 copper alloy silks, and total sectional area is equivalent to 95 squares copper cash, helps passing through fast of lightning current, reduces the possibility that equipment is struck by lightning, and has increased the fail safe of equipment.
3. metal derby of the present utility model is an aluminium block, good conductivity, and cost is low, is convenient to processing.
Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1;
Wherein: 1 is metal derby, and 2 is the copper alloy silk, and 3 is through hole.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Shown in Fig. 1～3, the utility model is used for conducting lightning current between the parts of wind turbine generator lightning protection earthing system relative motion, comprises metal derby 1 and copper alloy silk 2, and wherein metal derby 1 forms for the aluminium block casting.On the surface of metal derby 1 towards rotating part, preprocessing goes out a plurality of uniform copper wires and is pressed into the hole.Copper alloy silk 2 is 32 bundles, and every bundle is 512, and each copper wire that is pressed into metal derby 1 after the doubling is pressed in the hole, and the copper alloy silk after the doubling is 1024.On metal derby 1, have through hole 3.
Operation principle of the present utility model is:
The utility model is fixed on the conduction brush support, again support is fixed on the components A, be wrapped on the through hole 3 of metal derby 1 with lead, link to each other with part B again.When the lightning protection conduction brush is rack-mount, can adjust, guarantee that the copper alloy silk part of lightning protection conduction brush closely contacts with part B.Like this, when part B was moved with respect to components A, the copper alloy silk of conduction brush part and part B sliding friction were guaranteed the transmission of lightning current.
Main shaft with rotation is an example, is fixed on the conduction brush support after earlier the lightning protection conduction brush being adjusted, and guarantees that the copper alloy silk closely contacts with main shaft, is fixed on support on the bearing pedestal then.When main shaft rotates, the lightning current of the wheel hub lightning protection conduction brush by spindle unit can be conducted to ground network.
Copper alloy silk of the present utility model is the phosphor copper silk.
