Benefits of technology

The patent describes a transport apparatus for safely carrying and delivering stator segments used in wind turbine generators. The invention aims to reduce the risk of damage to the stator segments during transportation, caused by mechanical shocks and other factors.

Problems solved by technology

The speed of the rotor blades inducing the torque upon the rotor hub is limited.
Consequently, the rotational speed of the rotor hub is limited.
This may cause problems in particular when the wind turbine is directly driven.
Transport, handling and servicing of such large and heavy generators is challenging.
However, it turned out that this way of transporting the segment bears an inherent high risk of mechanical damage.
In particular, the conductive windings of the segments typically made from a metal like copper are easily deformed and damaged.
Malfunctioning segments are expensive and time consuming to repair.
Damages introduced during transport or handling of the segments may include short circuits that are difficult to locate and / or to repair.

Embodiment Construction

[0037]FIG. 1 shows a retainer 1 with a segment 2 of a stator. The segment 2 is locked to the retainer 1. The retainer 1 comprises a substantially rectangular base element 3 and a wall structure extending from the base element 3 in a perpendicular direction. The wall structure comprises four side walls 4 arranged along sides of the rectangular base element 3 and four pillars 5 respectively arranged in corners of the rectangular base element 3.

[0038]A female member 6 arranged as a recess is located on a top face of each pillar 5. Respectively, male members 7 are arranged on a bottom face of the base element 3. Each male member 7 is located in one of the corners of the rectangular base element 3 and projects from the base element 3 downwards. The male member 7 and the female member 6 are designed as a mating structure. Male and female member 7, 6 of retainers 1 stacked upon another engage each other with positive locking. The form fit provides stability of the arrangement of stacked re...

Abstract

A retainer for transporting and storing a segment of a stator which is part of a generator of a wind turbine includes a fastening device which is adapted to releasably fasten the segment to the retainer. The fastening device is attached to a base element of the retainer.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority of European Patent Application No. 12158820.6 EP filed Mar. 9, 2012. All of the applications are incorporated by reference herein in their entirety.FIELD OF INVENTION[0002]A retainer for transporting and storing a segment of a stator adapted to be part of a generator of a wind turbine is provided.BACKGROUND OF INVENTION[0003]Wind turbines known in the state of art may employ direct or indirect drive configurations. A wind turbine using an indirect drive configuration comprises a transmission device or gear box for transmitting and converting torque from a rotating rotor hub carrying a plurality of rotor blades and the generator converting mechanical energy to electrical energy. Another type wind turbines uses the direct drive configuration in which the torque directly transmitted to the generator. In either case, conversion of the mechanical energy to electrical energy is achieved by exerting a torque on t...
