Integrated carbon brush unit for wind turbines

Abstract

The present invention discloses an integration carbon brush device for an aerogenerator. The device comprises a carbon brush and a brush box; the carbon brush is fixed in the brush box; the carbon brush includes a carbon brush body; the brush box includes a brush box body, and a first fixed assembly and a second fixed assembly extending outwards are respectively arranged at two sides of the brush box body; the brush box body is provided with a through hole, one end of the carbon brush body is extended from the through hole to touch the surface of a conducting ring, and other end of the carbon brush body is fixed with a lead; the carbon brush body is provided with pressure grooves at two sides of the lead, an opening joint is arranged at the rear end of the lead, and the opening joint is fixed at the first fixed assembly; constant pressure springs are respectively arranged at the two sides of the top of the brush box body, and the constant pressure springs are embedded into the pressure grooves; and a contact point switch stop hook is fixed at the side surface of the carbon brush body, and the contact point switch stop hook is arranged at the lower portion of the pressure grooves. The integration carbon brush device for an aerogenerator employs an integrated carbon brush to take place of the multi-carbon brush combination structure in the prior art so as to solve the uneven pressure and reduce the incidence rate of faults such as high temperature, sparking and the burning of the surface of a conducting ring.

Description

technical field [0001] The invention relates to the field of generator accessory equipment, in particular to an integrated carbon brush device for a wind power generator. Background technique [0002] At present, the carbon brush devices used in wind farms all have the structure of a combination of multiple carbon brushes, because the structure of the combination of multiple carbon brushes is composed of multiple carbon brushes assembled in multiple brush boxes. There are the following problems: uneven pressure will lead to the current overload of some carbon brushes during the use of the product, and it is easy to cause high temperature, ignition, burns and other faults on the surface of the conductive ring; there are too many fault points. There are 6 carbon brush contact points, most of which have uneven overload current, high resistivity, inconsistent length of carbon brush wear, heat generation, expansion, etc., resulting in high failure rate; scattered assembly of mult...
