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 against a moving conductive surface of an electrical generator in a power plant without stopping motion of the moving conductive surface of the electrical generator, the brush holder assembly comprising:
an elongate mounting block being elongated in a longitudinal direction between a lower end and an upper end of the elongate mounting block, and the elongate mounting block including a front face, a rear face, an aperture extending from the front face to the rear face for receiving attachment hardware to fixedly secure the rear face against a base of the electrical generator, and a stationary brush release positioned proximate to the lower end of the elongate mounting block and extending upward therefrom; and a brush holder component removably mountable to the elongate mounting block such that the brush holder component is detachable from the elongate mounting block without removal of the attachment hardware, the brush holder component comprising a brush box and a channel for receiving a portion of the elongate mounting block therein, the brush holder component further comprising a brush catch that is spring biased to a first position for bearing against a rear-facing side of the conductive brush at a position above a lowermost edge of the brush box, wherein the brush catch is adjustable, in response to engagement with the stationary brush release positioned proximate to the lower end of the elongate mounting block, from the first position to a second position for disengaging the conductive brush.
