Background

One issue in relation to wind turbines is transfer of electrical power from a moving turbine nacelle to a stationary turbine tower. This involves high currents though cables with large cross-sections.

Sliding electrical contacts, capable of transferring high currents with low losses are an interesting possibility that could allow for more flexibility with regard to wind turbine design.      

Project description

The subject of study is the electrical properties of various contact configurations and contact materials in powder- or liquid form, e.g. graphite powder or a liquid metal with low melting point. The project will focus on laboratory testing, supported by analytical calculations and possibly finite element simulations. The project may include the following elements:

·      A literature study within the subject of electrical contact properties and collection of material data.

·      Construction of a test set-up for testing of electrical contact properties in collaboration with supervisors and people from the CEE workshop. Electrical, thermal and mechanical aspects must be considered.

·      Outlining a test plan that covers variation of parameters such as; contact material, pressure, current density and temperature.

·      Testing as well as evaluation and interpretation of test results.

·      Comparing test results against calculations and presentation of the results.

·      Based on the acquired experience; coming up with ideas for conceptual design of a three-phase sliding contact.
