The role of carbon brush slip ring in generator

Generator carbon brush is generally made of solid conductive system, the use of serious wear need to replace the carbon brush.The solid carbon brush cannot be in close contact with the conductive slip ring of the generator.The contact surface of carbon brush and slip ring is easy to enter dust, and the contact resistance increases.The contact resistor shares a lot of excitation voltage, the current loss is large, easy to produce sparks, cause fire.

CENO has solved the problem of solid carbon brush, improved the problem of bad contact and high contact resistance between the brush and the generator slip ring, reduced the excitation current loss and reduced the accident rate of the generator.This proposal is a generator with a rotor fixed on the rotating shaft and stator rotor winding carbon brush slip ring, which is characterized in that a carbon brush chamber is respectively arranged on the rotating shaft on both sides of the generator, a conductive liquid chamber is arranged at the bottom of the carbon brush chamber to join the conductive liquid, carbon carbon brush chamber is fixed on the generator through a fixed bracket.Both sides of the conductive liquid chamber are provided with anti-splash rings, and the anti-splash rings are fixed on the rotating shaft.A cup preventing guide cover is arranged on the upper part of the sliding ring, and a cup preventing guide cover is fixed on the wall of the carbon brush chamber.The slip ring is provided with a convex ring and a concave ring.The slip ring is fixed on the shaft through an insulating ring.The outlet of the overflow pipe in the conductive liquid chamber is arranged on the outside of the carbon brush chamber, the carbon brush chamber is closed, the carbon brush chamber is provided with an observation hole, and the inner wall of the bottom is provided with an insulating partition board.

This proposal can be clear from the recording, the effect of two carbon brush chamber of the slip ring respectively connected with the anode and the cathode lead wire of the rotor winding, and part of the slip ring impregnated in the conductive liquid, so rotating slip ring is in the process of conducting the axis of rotation, in both sides of the conductive liquid chamber set splash ring, fixed on the axis of rotation, the upper sliding ring set splash guard, splash guard on the carbon brush chamber wall, as a result, the slip ring along the axis of rotation, the conductive liquid velocity, the export of overflow pipe set, the outside of the carbon brush chamber, therefore, if there is excessive conductive liquid and water will overflow tube along the flow,An observation hole is arranged in the carbon brush chamber for easy observation of the internal conditions of the carbon brush chamber, and the inner wall at the bottom of the carbon brush chamber is insulated.It can be seen that the utility model has substantial characteristics and progress compared with the prior art, and the beneficial effect of its implementation is also obvious.
