Slip Ring, as an indispensable component for Wind Power Generating Set, plays a key role for transmitting the energy and the signal between its rotating and static parts. If its main control system would be like the brain of a giant and its paddle would be like an arm, so the Slip Ring where is hidden in the deep position of the cabin acts as its nerve center for connecting the above-mentioned. And, the Slip Ring is composed of the following core parts.
First, the outer cover and the inner core would be like a solid body
The outer cover of the Slip Ring, like a solid armor, is made of metallic material for the purpose of providing related installation spaces for its inner precious components and also for protecting against harsh environments such as the sand, the extreme temperature and the strong wind in the high altitude as well. Inside the cover, there is the inner core of the Slip Ring which is also made of the metal. The inner core, like a framework of the overall Slip Ring, is responsible for supporting its inner carbon brush and guide wheel for offering stable electrical contact points.
Second, the conductive ring and the brush would be like the core components for its dynamic transmission
Those are the most important operating components. The conductive ring (the rotator) which is installed on the rotating component of the equipment is composed of one or more metallic rings of which will represent an indispensable transmission channel for the purpose of transmitting the current and the data in the process of its rotating operating. And, the brush (the stator) which is installed on the static component is composed of wearable materials such as graphic, composite metal or precious metals. The brush, with the dependence on elastic pressure, will be closely contacted on the surface of its rotating conductive ring for the purpose of realizing seamless transmission for the power and the control signals in the process of its dynamic friction.
Third, the carbon brush and the guide wheel would be like a precious contact partners
In the structure of the Slip Ring, the carbon brush and the guide wheel act as the important components for realizing electric transmission. The carbon brushes can be made of different materials including graphic, composite metal or fiber for the purpose of realizing excellent wear and conductive performances, ensuring keeping stable electric contact in the period of its long operating. And, the guide wheel is generally designed a round or cylindrical shape for the purpose of matching up its carbon brush in the process of its rotating operating. The above-mentioned design will not only provide a larger contact area but also reduce friction resistance, ensuring the stable operating of the Slip Ring.
Four, precious bearing would be like a bodyguard for ensuring a stable operating
In the process of the high-speed rotating operating, the motor will bear a huge mechanical stress. Inside the Slip Ring, there is a small and precious steel bearing for the purpose of ensuring a stable operating of the rotor at a high speed, not only protecting the system against mechanical breaking down but also prolonging the overall service life as longer as possible.
In conclusion, thanks to the above-mentioned four precious structures, the motor can not only capture the wind but also keep smooth power-and-signal transmission in the process of its 360-degree continuous rotating.
