Wind turbine with electric converter module for arc flash protection
A wind turbine patent (Publication Number: US12003079B2) has been granted for a wind turbine design that includes a unique electric converter module. The wind turbine comprises a rotor blade system, an electric generator, a tower with a nacelle housing the electric generator, and an electric converter module. The electric converter module consists of a first section with a top part, bottom part, and four side walls forming an enclosure to house electric protective devices and conductors for grid connection. A second section adjacent to the first enclosure houses an electric converter system to convert power from the generator for grid connection. The design also includes auxiliary equipment for operation in a de-energized state, with cooling systems and pressure release mechanisms to ensure safety and efficiency.
Furthermore, the patent details the manufacturing method for the electric converter module, involving the creation of two module parts - the first section housing protective devices and conductors, and the second section housing the converter system. The assembly of these parts forms the electric converter module, which is crucial for the wind turbine's operation. The design also includes a third section with protective devices and conductors for electric connection to an external source. The patent emphasizes safety features such as pressure-resistant walls, sealing mechanisms, and cooling systems to prevent damage from arc flashes. Overall, the wind turbine patent showcases an innovative design for efficient power conversion and grid connection, with a focus on safety and operational reliability.
