Brush holder apparatus, brush assembly, and method

摘要

Devices and methods of use for brush holder assemblies are disclosed. Brush holder assemblies including a mounting block and a brush holder are disclosed. Also illustrated is a brush holder assembly including a first portion in sliding engagement with a second portion. In some embodiments the brush holder includes a channel, such that at least a portion of the mounting block is disposed within the channel of the brush holder.

主权项

1. A method of removably attaching a brush holder component to an electrical generator in a power plant without stopping a moving conductive surface positioned adjacent a conductive brush held by the attached brush holder component, the method comprising:
slidably engaging a channel of a brush holder component, wherein a brush box of the brush holder component carries a conductive brush, with an elongate mounting block while the elongate mounting block is fixedly attached to a mount base of the electrical generator, the elongate mounting block being elongated in a longitudinal direction between a lower end and an upper end, the elongate mounting block including a front face, a rear face opposite from the front face and abutting the mount base, and an aperture extending from the front face to the rear face for receiving a mounting fastener to fixedly attach the elongate mounting block to the mount base; advancing the brush holder component along the elongate mounting block toward the moving conductive surface of the electrical generator until a stop element defined by the elongate mounting block at a position between the rear face and the front face engages a corresponding element of the brush holder component; engaging a stationary brush release positioned proximate the lower end of the elongate mounting block with a spring-biased brush catch of the brush holder component so as to adjust the brush catch from a first position wherein the brush catch engages a lateral side of the conductive brush to inhibit movement of the brush relative to the brush box to a second position wherein the brush catch disengages the conductive brush to permit movement of the conductive brush relative to the brush box; and releasably locking the brush holder component to the elongate mounting block to prevent withdrawal of the brush holder component in the longitudinal direction by mating a lock element of the elongate mounting block positioned between the rear face and the front face with a corresponding lock element of the brush holder component.
