Description
Technical Field
[0001] The utility model relates to the field of maintenance of pitch-changing communication slip rings, in particular to a detection device for communication slip rings. Background Art
[0002] The variable pitch slip ring is a device for signal transmission and deceleration, which is mainly used in wind turbines. When the wind turbine is running, it is necessary to use a facility to play a very good signal transmission role, so that its power generation capacity can be enhanced and the stability of the entire signal can be ensured. At this time, the variable pitch slip ring plays such a role. Because sometimes the wind speed is relatively high, and sometimes the wind speed is relatively low, this will affect the work of the power supply machine. However, when the wind turbine uses the variable pitch slip ring, it can adjust the blades to a certain extent through the transmission of its own signal without the problem of blade instability. The variable pitch communication slip ring often has faults such as needle skipping, oil stains and carbon powder accumulation, resulting in signal loss. After the on-site self-repair, you can only use the naked eye to check whether the slide surface is clean and whether there are simple fault points where the slide needle is not in the corresponding slide under the tower;
