Condition Monitoring for screw connections

Screw connections are among the most heavily stressed parts of a wind turbine. As safety-relevant components, screw connections are exposed to continuously acting dynamic forces during the life of a wind turbine, which can cause cracks, damage and fractures in the bolts. For a safe and reliable operation of the wind turbine, the bolted connections must be checked regularly. Weidmüller's condition monitoring systems provide information on the condition of each screw at the connection of rotor blades and tower segments. The combination of customer-specific engineering and application competence results in a custom-fit monitoring solution for your screw connections.

Weidmüller offers different monitoring options depending on customer requirements.
Depending on the sensor type, Weidmüller systems detect:

• broken screws
• torn nuts
• loosened screw connections.

Weidmüller also develops application-specific sensors to ensure an easy integration into the overall monitoring system. In doing so, the focus is set on a

• quick installation and removal of the sensors in the field
• cost-effective and simple wiring

An evaluation unit records the sensor data and processes them by an integrated control system. It forms the interface to the main controller. Optionally, the data can be made available in the SCADA via remote access. Depending on the type of wind turbine, the dimensions, functions and interfaces of the evaluation units can be customized. Depending on the customer's requirements, the monitoring system can also be integrated into the wind turbine's safety circuit to ensure that the turbine is shut down safely in the event of a damage.
