In the motor, with huge decade-meter-length blade rotating in the wind, the wind power will be continuously transmitted into powerful green energy. However, do you consider that, when the blade is continuously rotating with its 360-degree, why those cables responsible for controlling related angle and transmitting operating data are not be twisted off? The answer is the back hero-Slip Ring which is an unimpressed but indispensable component.
As "the lifeline" for connecting function between the rotating component and the fixed system, the Slip Ring reflects significant technology advantages.
First, the Slip Ring perfectly solves the problem for the "twist-off crisis" on the rotating system. The traditional guide line, in the condition of continuous rotation, will be easily twisted off. However, the Slip Ring, through static brush and rotating conductive electric ring, keeps a dynamic contact, realizing a 360-degree smooth rotation. The above-mentioned not only protects the cable against its twisting off and mechanic wear but also prolongs the equipment service life as well as reduces the overall equipment maintenance costs.
Second, the Slip Ring acts as "all-powerful transmission channel" for the power and the signal. In modern slip rings, they can not only carry large current to provide stable and reliable power for its angle-information control system for the purpose of ensuring the blade can accurately adjust its angle according to the wind speed, but also can transmit each and every sensor data and related control signals. Therefore, the above-mentioned stable and seamless transmission for the power and the signal serves as the basic foundation on its smart control and high-effective power.
Moreover, the Slip Ring is required with "the environment protection capabilities". The Wind Plant is generally installed in remote areas where is faced with a harsh environment such as high moisture, strong vibration, extreme temperature and even high salt and spray. Therefore, the Slip Ring is normally designed with a wearable cover and a precious sealed design, which can be protected against the wind and send erosion and extreme temperature changes for the purpose of guarantee its inner contact points with its low resistance and high reliability under the harsh environment.
Finally, thanks to its lower maintenance and high-integration design, the Slip Ring can bring visible economic benefits for the Wind Plant. With the technology advancement, the current Slip Ring is not only designed as a compact structure and a lower weight but also will be advanced with a maintenance-free and smarter trend. Part of those advanced Slip Rings even integrate a real-time monitor module that can warn the potential breakdown in advance, which will transform passive maintenance into proactive prevention for the purpose of reducing the downtime of the motor.
In conclusion, in spite of its small volume, the Slip Ring is required with excellent advantages on its twist-off resistance, strong transmission, harsh environment prevention as well as lower maintenance, playing an indispensable role in guaranteeing the safety, high effectiveness and the longer service life for the motor.
