Description
Technical Field
The utility model relates to a wind turbine generator system turns round cable monitoring devices.
Background
The twisted cable is used as a component with complex operation conditions in the wind generating set, and plays a role in transmitting the electric energy of the wind generating set, and the cable has large circulating current. When the wind turbine generator runs, the twisted cable can rotate along with the fan main machine, and when the degree of torsion of the twisted cable reaches a set value, the wind turbine generator can be protected by untwisting the twisted cable. At present, the torsion degree of a twisted cable can only be monitored in real time through a sensor on a wind turbine generator. When the unit breaks down, the twisted cable of the wind generating set cannot be normally untwisted, and the cable can be cracked after the rotation degree of the twisted cable exceeds the allowable value of the cable, so that the cable is short-circuited, and great potential safety hazards exist. In addition, when the wind turbine generator runs for a long time, the twisted cable can generate abrasion, and the cable sags and other risks. All problems cannot be monitored by sensors on the wind turbine.
Disclosure of Invention
