Slip rings for wind turbine’s electrical pitch drive system
Signal transfer system for wind turbines
Key components for wind turbine performance
The Signal and Power Transfer System (SPTS) is part of the wind turbine’s electrical pitch drive system.
Also referred to as “pitch rings” or “pitch slip rings” or “hub slip rings” its purpose is to transfer power and control signals to the wind turbine hub and its components. It provides communication between the hub and the turbine controller.
Ensuring turbine’s continuous operation
A turbine constantly adjusts its blade orientation (also called pitch) to both the wind speed and rotation speed to optimize the aerodynamics and maximize power production.
Therefore, the accurate control of blade pitch for a wind turbine is critical to proper operation and optimum production. The robust design and engineered quality of the SPTS ensures reliable communication between the hub and the turbine controller during operation and through any environmental conditions.
The most important features and capabilities of an SPTS include:
- high reliability of contact hardware for both the power and the signal transfer;
- ability to operate in any environmental conditions;
- Quick and easy maintenance without requiring frequent inspections.
USDK656 SPTS - Signal & Power Transfer System
Mersen now offers the USDK656 SPTS - Signal & Power Transfer System, using Mersen’s premium carbon brush grades to transmit signal, data and power. The carbon grades are based on decades of tribology research and field application experience.
The brushes feature low wear rates, which translates into less dusting, reliable data transfer and power transmission to the hub. The design was optimized to withstand harsh operating conditions and a wide range of vibration frequencies in the turbine.
The unit features an integrated connection cabinet allowing for a quick installation and easy maintenance. Designed according to ISO, UL and CSA standards - a Class II IP54 seal provides extra protection from environmental contaminants.
An easy cleaning schedule of once every other year will keep this component running successfully in your turbines for years ahead
Tailored products and solutions for wind turbine OEMs
A number of wind farms are successfully running Mersen’s SPTS products. A number of platforms have received our solutions and are now satisfied customers. We strive to improve site reliability numbers and reduce the technicians’ time up-tower.
