Vestas Grounding Brush Holder 753347

When the fan is running, due to the unbalanced magnetic field of the magnetic circuit, there is a rotating magnetic flux that intersects with the rotating shaft; when the rotor winding has a ground fault, a ground current will be generated, and the excessive current of the generator shaft will easily lead to the inside and outside of the generator bearing. There are problems such as washboard patterns, locking, and running circles in the lap. Seriously, the generator needs to be replaced, which will cause serious economic losses. Therefore, there is an urgent need for a grounding device for wind turbine generators. This brush box is a shaft grounding brush holder from Vestas. The whole brush box is as shown in the picture above and is divided into 5 parts, 1. Bolt, 2. Brush cap, 3. Brush box, 4. Nut, 5, Carbon brush composition. This brush box is fixed to the fixing plate by two nuts, so that the carbon brush and the main shaft are in contact to form a path to lead out the shaft grounding current! This brush box uses the cost-effective H62 material, H62 has good mechanical properties, plasticity under hot state Good, good machinability, corrosion resistance.

As shown, the assembled case of 753347.
