ができることは勿論である。This brush holder 3 holds the rotating machine brush 2 in a fixed position on the collector ring 1, and is pressed by a constant pressure spring 4 (:) so that it can slide on the rotating collector ring 1. The rotary machine brush 2 is configured to be in sliding contact with the rotating machine brush 2 while maintaining a good and safe contact pressure.The rotating machine brush 2 is also provided with a pigtail 5, and a pressure is applied to the pigtail 5.Abrasion detection section 7 is insulated from the rotating brush 2, and wear of this brush 2 (=
When the brush 2 moves downward, it is pushed by the convex part of the brush 2, and the mechanical contact 8 of the wear detection section 7 opens and closes to output a pulse signal. Although a mechanical brush wear detection means is used in section 7, it is of course possible to use an optical brush wear detection means.

ている。On the other hand, the pulse signal detected from the wear detector 7 is transmitted to the brush wear converter 9. This brush wear variable part 9
is composed of a pulse detection circuit 10, a wear alarm calculation/synthesis circuit 11, and a pulse setting generation circuit 1. The pulse detection circuit wt10 integrates the pulse signals detected and output from the wear detection section 7, and the pulse setting generation circuit sets and outputs a predetermined number of pulses. 11, the pulse/Lt pulse a detected by the pulse detection circuit 1o is compared with the number of pulses set in advance by the pulse setting generation circuit 12. Then, the pulse is detected from the number of pulses of the pulse setting generation circuit 12. It is configured such that when the number of pulses in the circuit 1o increases, an output signal is outputted to a brush wear/warning device (not shown) in the fourth secondary stage.

たパルス数が後者の設定されたパルス数より大となる。When the rotating machine is operated, the brush 2 in contact with the collector ring 1 is jI! As the rotating machine brush 2 becomes worn, it moves downward in the drawing position. Then, the side surface of the rotary machine brush 2 (= the provided uneven part 6 also moves downward (==), so this uneven part 61: the mechanical contact table 8 of the installed wear detection part 7 opens and closes) A pulse signal is generated in response to the opening/closing operation of the mechanical contact 8. This generated pulse signal is transmitted to the brush wear converter 9. The pulse detection circuit 10 of the brush wear converter 9 detects wear. The pulse No. 16 transmitted from the pulse detection circuit 10 is integrated, and the result is input to the wear alarm calculation/synthesis circuit IN.The wear alarm calculation/synthesis circuit 11 uses the integrated pulse number input from the pulse detection circuit 10 to generate the pulse setting. A comparison calculation is made with a preset number of pulses in the circuit 12, and the former number of input pulses is larger than the latter set number of pulses.
