Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The following detailed description is provided for the specific embodiments of the present invention.

Referring to fig. 1 to 4, an embodiment of the present invention provides a carbon brush for a wind turbine, the carbon brush for a wind turbine includes: carbon brush 1, be connected with wire 2 on the carbon brush 1, 2 outside covers of wire are equipped with line body leather sheath 3, still include: the carbon brush 1 is connected with a protective seat 4, and the lead 2 and the wire leather sheath 3 are positioned in the protective seat 4; the elastic limiting component 6 is connected in the protective seat 4, and the elastic limiting component 6 is in contact with the wire body leather sheath 3.

It should be noted that: clearance department that is not protected by line body leather sheath 3 at carbon brush 1 and wire 2 sets up protection seat 4, make the point of being dragged between the two by the clearance department that is not protected by line body leather sheath 3 on wire 2, shift to the position of line body leather sheath 3 with the contact of protection seat 4 upper end, make the clearance department that is not protected by line body leather sheath 3 on the wire 2 can not receive the dragging, therefore, can not cause this department the cracked condition to appear, the elasticity restriction subassembly 6 that sets up simultaneously, can reduce because of the swing radian and the amplitude that motor vibration produced 2 wires inside and line body leather sheath 3, thereby can further promote the life of whole device.
