Sealing device

A sealing device comprising:

• a sealing ring, wherein the sealing ring is insulative and is configured to form a dynamic seal to a conductive component, the sealing ring comprising a fabric portion, wherein the fabric portion is arranged on a radial end of the sealing ring away from the conductive component;
• a plurality of support bodies, wherein the plurality of support bodies are fixed on the sealing ring along a circumferential direction of the sealing ring, wherein the plurality of support bodies provide a radial force between the sealing lip and the conductive component;
• and
• a first detection unit, wherein the first detection unit comprises two or more first support bodies from the plurality of support bodies, two or more first cables respectively electrically connected to corresponding two or more first support bodies, and a loop detection device electrically connected to each of the two or more first cables;
• wherein the two or more first support bodies are arranged at the sealing ring and radial ends of the two or more first support bodies are covered with an insulating elastic material at the sealing lip, wherein the two or more first support bodies, the conductive component, the loop detection device, and the two or more first cables form a communication loop.

A wind turbine comprising:

• one or more bearings;
• and
• one or more sealing devices, wherein at least one of the one or more sealing devices comprise:
• a sealing ring, wherein the sealing ring is insulative and is configured to form a dynamic seal to a conductive component, the sealing ring comprising a fabric portion, wherein the fabric portion is arranged on a radial end of the sealing ring away from the conductive component;
• a plurality of support bodies, wherein the plurality of support bodies are fixed on the sealing ring along a circumferential direction of the sealing ring, wherein the plurality of support bodies provide a radial force between the sealing lip and the conductive component;
• and
• a first detection unit, wherein the first detection unit comprises two or more first support bodies from the plurality of support bodies, two or more first cables respectively electrically connected to corresponding two or more first support bodies, and a loop detection device electrically connected to each of the two or more first cables;
• wherein the two or more first support bodies are arranged at the sealing ring and radial ends of the two or more first support bodies are covered with an insulating elastic material at the sealing lip, wherein the two or more first support bodies, the conductive component, the loop detection device, and the two or more first cables form a communication loop.
