Wear sensor for a wind turbine

摘要

A system comprising a first wind turbine structure and a second wind turbine structure, wherein the first wind turbine structure and the second wind turbine structure are rotatable with respect to each other is provided. A safety bearing element is mounted to the first wind turbine structure such that the second wind turbine structure is in slideable contact with a contact surface of the safety bearing element if a distance between the first wind turbine structure and the second wind turbine structure is reduced below a predetermined reference value. The safety bearing element comprises an electrical indicating circuitry with an indicating conductor, wherein the indicating circuitry is connectable to a wear controller system such that a signal is generatable by the indicating circuitry and transmitted to the wear controller system until the indicating conductor is damaged due to the slideable contact of the second wind turbine structure with the safety bearing element.

1. A system for a wind turbine, the system comprising;
a first wind turbine structure; a second wind turbine structure, wherein the first wind turbine structure and the second wind turbine structure are rotatable with respect to each other; and a safety bearing element which is mounted to the first wind turbine structure such that the second wind turbine structure is in slideable contact with a contact surface of the safety bearing element if a distance between the first wind turbine structure and the second wind turbine structure is reduced below a predetermined reference value, wherein the safety bearing element comprises an electrical indicating circuitry with an indicating conductor, and wherein the electrical indicating circuitry is connectable to a wear controller system such that a signal is generatable by the electrical indicating circuitry and transmitted to the wear controller system until the indicating conductor is damaged due to the slideable contact of the second wind turbine structure with the safety bearing element; wherein the second wind turbine structure surrounds the first wind turbine structure.
