For the maintenance of the components of the conductive sliding ring brush holder, the common carbon brushes used by electric power enterprises are all advanced tracking constant pressure brush holders, which can make the maintenance of the components free of adjusting the spring pressure. But attention should be paid to the abnormal fatigue state of spring when it loses elasticity. Once this phenomenon occurs, it will cause poor contact caused by insufficient pressure, and may cause the phenomenon of lightning to damage the surface of the slip ring. So the spring fatigue phenomenon needs to be paid close attention to in the process of overhaul. The operating temperature of the conductive slip ring of the unit is generally about 50 degrees. Once the temperature is abnormal, it may be that the internal parts have unnecessary defects. Staff members should pay more attention to it in order to deal with it in time. It is also necessary to maintain the internal structure parts of the conductive sliding ring regularly, whether there is blockage when rotating, whether the insulating parts are polluted, and so on. Only by focusing on the details and eliminating all the defects in the overhaul can the long-term stable operation of the unit be achieved.
Purpose of conductive sliding ring brush: conductive ring is a device consisting of ring and brush, which can provide signal and power transmission between fixed parts and running parts of various equipment in arbitrary rotating state. The ring of conductive ring, also known as axle core, is composed of several conductive rings which are insulated from each other. The brush keeps contact with each ring correspondingly. Brush is a kind of precious metal alloy elastic material, which has excellent wear resistance, conductivity and stability. The brush keeps V-shaped contact with the metal on the ring through elastic force. Thus, when the conductive ring rotates, the ring keeps sliding contact with the brush, thus realizing the function of transmitting current when the conductive ring rotates.
According to the different requirements, installation conditions, using environment and working principle of conductive rings, they can be divided into cap type, split type, through-hole type, wind power type, mercury type, optical fiber type, high frequency type, waterproof and moisture-proof type, high and low temperature type, carbon brush type and other special specifications of customized sliding rings. Mainly in order to adapt to the special use conditions of all walks of life, conductive rings are widely used in military and civil fields such as national defense, ocean, mineral resources, energy, construction, security, industrial automation and so on, as key components of various equipment in science and technology. Provide perfect current, complex signal and power transmission solutions for various facilities.
