Materials and Electrical Parameters
Material: Copper-graphite composite carbon brush (high copper content C80X type, original Schunk factory matching material), suitable for doubly-fed generator rotor conductive slip ring
Rated current: Single branch rated 104A (model 104W prefix represents 104A rated load), the entire generator set has 12 sets of 12 carbon brushes
Operating environment: Engine room – 40℃ to +85℃, dust-proof and moisture-proof, applicable for both onshore and offshore wind power
Installation structure: Spring constant-pressure brush holder integrated type, 20×40×63 is the carbon brush blank size, with sufficient wear allowance

 Installation Position and Usage
Installation location: Rotor collector ring at the rear end of the generator (slip ring), connecting to the rotor circuit of the converter, transmitting rotor excitation electrical energy
Core function: Stationary carbon brush → Rotating slip ring conductive, is a key vulnerable component of the doubly-fed wind turbine rotor frequency conversion circuit; excessive wear will cause generator grounding and converter reporting rotor overcurrent faults
