Abstract

The invention discloses an integrated doubly-fed wind generator carbon brush holder assembly comprising an assembly support rack, a number of integrated carbon brush assemblies and an earthing brush holder assembly, wherein the integrated carbon brush assemblies and the earthing brush holder assembly are fixed on the assembly support rack, the assembly support rack comprises a first bending plate and a second bending plate, two support rods are arranged between the first bending plate and the second bending plate, two ends of each integrated carbon brush assembly are fixed on the support rods, the earthing brush holder assembly is fixed on the second bending plate, the second bending plate is provided with a number of support stand feet, the integrated carbon brush assemblies comprise a one-piece carbon brush, and one end of the one-piece carbon brush contacts with a surface of an electrically conducting ring. According to the integrated doubly-fed wind generator carbon brush holder assembly, the integrated carbon brush is used for replacing a multi-carbon brush combination structure of the prior art, and a problem of uneven pressure is solved; incidence rates of faults such as high temperature, sparking, burn of the surface of the electrically conducting ring and the like can be lowered; a structure of the assembly support rack produces fixing effects, and electrical faults caused by vibration can be prevented in a working state.

Description

technical field [0001] The invention relates to the field of generator accessory equipment, in particular to an integrated doubly-fed wind power generator carbon brush holder assembly. 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 as...
