[0002] The brush is located at the dynamic and static junction of the generator. It is a device for dynamic and static contact and energy exchange of the generator. When the unit is running, the generator brush needs to be in close contact with the surface of the collector ring and rub continuously to realize the contact between the dynamic and static parts of the generator. Energy transfer, precisely because of such long-term and continuous mechanical friction, the wear and replacement of generator brushes is frequent and daily, and the brushes that are worn to a certain extent need to be replaced in time, otherwise there will be contact at the top of the brush holder. The danger of slipping and damaging the surface of the collector ring, or even ignition at this position may cause failures such as heating, breakage or loosening of components, resulting in non-stop of the unit. Therefore, it is necessary to detect and alarm the amount of brush wear in real time. ;

[0003] At present, the detection of generator brush wear is mainly through the simulation of the actual operation of the motor. Once the motor is started, it must not be stopped unless the brush is damaged, and it is realized by periodic inspections by maintenance personnel. The brushes of the generator are fixed by the brush holder. On the brush holder evenly distributed around the main shaft of the generator, the installation space is extremely compact, and because of the requirement of noise reduction, the brush chamber of the generator is usually isolated and operated in the soundproof enclosure. Due to the characteristics of the above installation arrangement, every time During the inspection, the operation and maintenance personnel must pass through the soundproof cover, close to the carbon brush holder, and observe the operation and wear of the brush with the naked eye. This method of manual periodic inspection requires the inspection personnel to be close to the rotating power generator frequently. The machine observes the wear of the brushes with the naked eye, and determines which brushes need to be replaced through the marking lines on the brushes. This detection mode not only has the disadvantages of heavy workload and low efficiency for maintenance personnel; In addition, this detection method has many interference factors, large errors, and is not objective enough. It cannot detect potential safety hazards early to ensure equipment safety, and it is not scientific for fault diagnosis. Hours of non-stop operation, large power consumption, and long detection cycle greatly reduce the speed of product development and update. In view of these situations, in order to avoid the above technical problems, it is necessary to provide a brush material performance detection device to overcome the current situation. have said defects in the technology
