Embodiment Construction

[0034] In the following description of the embodiments, reference to the drawings is made by illustrating examples in which the invention may be practiced. It is understood that other embodiments may be made without departing from the scope of the disclosed invention.

[0035] In one embodiment, the present electrical connection arrangement is specifically designed to provide an efficient and / or safe electrical connection between electrical conductors provided on a stationary element / object and other electrical conductors provided on a rotating element / object, such as in In a wind turbine with a yaw drive. In fact, in such wind turbines, the nacelle in which the generator is embedded turns and rotates according to the wind, while the conductors used to deliver the generated electricity to the base of the wind turbine are usually fixed along the conductor path along the mast of the wind turbine. Fixed.

Abstract

The invention discloses a slip ring assembly. The slip ring assembly comprises: a plurality of conducting disks being spaced-apart and stacked mounted along a common rotation axis, each being electrically connectable and fixedly securable to a generator mounted in a rotatable nacelle of a wind turbine so that a rotation of the rotatable nacelle triggers a rotation of the conducting discs; and a plurality of slip ring devices each being electrically connectable and mechanically securable to a fixed electrical distribution conductor mounted to a fixed pole so as to have a fixed position relative to the fixed pole, each one of the plurality of the slip ring devices comprising upper and conducting fingers arranged so as to rotatably receive a respective conducting disk therebetween and provide an electrical connection between the conducting disks and the slip ring device during the rotation of the nacelle.

Description

technical field [0001] The present invention relates generally to electrical arrangements in wind turbines, and more particularly to slip ring assemblies suitable for use in orientable wind turbines. Background technique [0002] A typical wind turbine is usually made from a mast with a number of tubular sections mounted together, with the nacelle positioned at the top of the mast. Electrical cables and / or rigid aluminium / copper conductors attached to the tubular sections are typically used to transport the electricity generated by the generator from the nacelle to the base of the wind turbine. [0003] Horizontal axis wind turbines are usually provided with a yaw drive mounted in the nacelle and designed to orient the rotor such that the blades face the wind regardless of the direction of the wind. When the direction of the wind changes, the yaw drive is operated to rotate the nacelle in the appropriate direction so as to face the wind while the tubular section remains fix...
