FHS Series Wind Turbine Slip Ring Parameter Table

Typical Application

1.Efficient power transmission of large onshore wind farms

Case 1:Large-scale onshore wind farms have hundreds of wind turbines of different models, with single-unit power ranging from 2MW to 5MW. When the wind turbines in the wind farm are running, the blades and hubs continue to rotate, while some equipment in the nacelle is stationary. At this time, the wind turbine slip ring serves as the core link between the rotating parts and the stationary parts of the wind turbine, ensuring that the electricity converted from wind energy can be efficiently and stably transmitted to the power grid.

2.Adaptation to harsh environments of offshore wind farms

Case 2:The wind turbine slip ring selected by a certain wind farm has an ultra-high protection level and adopts a fully sealed structure to effectively prevent the intrusion of salt spray and water vapor. Its outer shell is made of corrosion-resistant high-strength alloy, and the internal key components have undergone special surface treatment to further enhance corrosion resistance. In terms of signal transmission, the slip ring has excellent anti-interference ability. Even in complex electromagnetic environments, it can accurately transmit key monitoring and control signals such as wind speed, wind direction, and blade angle to ensure that the intelligent control of the wind turbine can be smoothly realized. Since the wind farm was put into operation, the wind turbine slip ring has been running stably with an extremely low failure rate, which effectively guarantees the reliable operation of offshore wind turbines.

3.Precise control of wind turbine pitch systems

Case 3:In a large wind farm, each wind turbine's pitch system is equipped with a dedicated pitch slip ring. When the wind speed changes, the wind turbine needs to adjust the blade angle in real time to capture the best wind energy. At this time, the pitch slip ring is responsible for transmitting the control signal from the wind turbine control system to the pitch motor, and at the same time transmitting feedback signals such as the motor operating status back to the control system. A certain brand of pitch slip ring, with its high-precision manufacturing process, can ensure the accuracy and timeliness of signal transmission, so that the blade angle adjustment error is controlled within a very small range. In actual operation, wind turbines equipped with this pitch slip ring can quickly and accurately adjust the blade angle at different wind speeds, effectively improving the efficiency of wind energy utilization. Compared with wind turbines that do not use this slip ring, the power generation is increased by 8% - 10%.

4.Remote monitoring and operation and maintenance support for wind farms

Case 4:A modern wind farm has introduced an advanced remote monitoring system, which realizes high-speed and stable transmission of wind turbine operation data through wind turbine slip rings. The wind turbine slip rings used in this wind farm integrate data transmission channels and can simultaneously transmit multiple types of data, such as vibration data, temperature data, electrical parameters, etc. of the wind turbine. These data are transmitted to the monitoring center through slip rings, and the operation and maintenance personnel can grasp the operating status of the wind turbine in real time and discover potential faults in time. For example, when the vibration data transmitted by the slip ring fluctuates abnormally, the monitoring system can quickly issue an early warning, and the operation and maintenance personnel can arrange maintenance in advance to avoid the expansion of the fault, effectively reducing the downtime of the wind turbine and improving the overall operation and maintenance efficiency of the wind farm.
