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 brush holder assembly for removably installing a conductive brush in contact with a conductive surface of an electrical generator in a power plant without stopping motion of the conductive surface of the electrical generator, the brush holder assembly comprising:
a fixed mount for affixing to a base of the electrical generator; a brush holder including a brush box having a plurality of sidewalls including a first side wall, a second side wall, and a third side wall; a conductive brush positioned in the brush box for longitudinal movement therein, the conductive brush including a first side surface facing the first side wall, a second side surface facing the second side wall, a third side surface facing the third side wall, a fourth side surface, and a lower surface; the brush holder including the brush box being slidably engageable with the fixed mount from a disengaged position in which the lower surface of the brush is not contacting the conductive surface of the electrical generator to an engaged position in which the lower surface of the brush is contacting the conductive surface of the electrical generator; and means for forcing the second side surface of the brush against the second side wall of the brush box as the brush holder is moved to the disengaged position to prevent longitudinal movement of the conductive brush within the brush box.
