く行なえるブラシ摩耗検出装置全提供するものでめる。However, in the conventional device configured as described above, the brush fi+ is worn out beyond the wear limit. Therefore, in order to completely prevent flashover accidents due to transient wear of the brush (11), during daily inspections, the brush +11? is collected from the brush holder (5) and the wear amount of the brush (1) is measured on the entire scale or Measurements had to be made with a caliper, etc.As a result, for example, since there are 500 to 800 brushes in a large rotating electric machine, the number of brushes (1)
It took a lot of time to maintain. In addition, in some cases, transient wear of the brush fi+ may lead to a complete flashover accident.10 This invention was made in view of the drawbacks of the conventional products as described above, and it is possible to electrically check the condition of the edges of the brush. The present invention provides a complete brush wear detection device that allows maintenance of the brushes to be performed without requiring much time by detecting the wear of the brushes.

For example, the brush holder (51) is provided at a position corresponding to the wear limit of the brush fi+, and when the brush +11 reaches the wear limit, it is necessary for the receiver to exchange the original signal with the transmitter (7). 〇Next, let's talk about the operation 1i528A.As shown in Figure 4, the brush (moon) is not worn out, and in this state, the original signal is cut off by the brush (1), and the transmitter (7)
) and the receiver (K device 81), and it can be determined that the brush il+ has not reached its wear limit.
When l wears out, the cutoff state of the original signal is released, and the original signal is exchanged between the transmitter (7) and the receiver (8). is operated and it is determined that the brush +11 has reached its wear limit. In this way, the wear limit of the brush 11) can be easily determined electrically, and unlike conventional methods, during daily inspections, the brush (1) can be removed from the brush holder (5) and measured with a scale or caliper. ) wear 1t' (r4), maintenance of the brush fl+ can be carried out without having to completely install it for a long time.Furthermore, there is no risk of flashover 4B&? etc. due to transient wear of the brush +11.
