Description

Technical Field

[0001] This utility model relates to the technical field of cleaning devices, and in particular to a generator slip ring carbon powder cleaning device. Background Technology

[0002] During operation, the generator slip rings and carbon brushes continuously rub against each other, generating a large amount of carbon powder, which causes multiple problems. Carbon powder accumulation on the surface of the slip rings or the inner wall of the dust collection hood may lead to partial discharge, short circuit, or even burnout accidents. To address these problems, automatic carbon powder cleaning devices have become a key retrofit project for generator sets (especially wind turbines and hydro turbines).

[0003] For example, in a class of prior art represented by application number CN202323438010.7, the main structure includes a bottom fixing device, a device holder, and a toner cleaner. The bottom fixing device is set on the slip ring chamber, and multiple device holders are set on the bottom fixing device. Each device holder has a toner cleaner at its end. The doubly-fed generator slip ring toner cleaning device has a lightweight, simple, and low-cost structure. During use, the bottom fixing device is set on the slip ring chamber, and then the toner cleaner is placed on the slip ring. As the slip ring rotates, the toner on the slip ring is cleaned off, eliminating the need for manual cleaning of the slip ring toner later. This avoids maintenance personnel inhaling large amounts of toner when cleaning the toner, avoids unnecessary equipment downtime, and eliminates safety hazards caused by arcing and short circuits.

[0004] During use, it was found that existing toner cleaning devices are inconvenient to remove toner when cleaning generator slip rings. Due to static electricity, the toner will re-adhere to the generator slip rings, resulting in incomplete cleaning. Therefore, there is an urgent need for a generator slip ring toner cleaning device.
