Abstract

The invention provides a wind power generator. The wind power generator comprises a tower barrel, a cabin, a wind wheel, miniature wind power generation equipment, a control unit and a box type transformer. The cabin is arranged at the top end of the tower barrel. A speed-up gearbox and a generator body are arranged in the cabin. The wind wheel is connected with an input shaft of the speed-up gearbox through a spindle. An output shaft of the speed-up gearbox is connected with the generator body. The cabin, the wind wheel and the tower barrel are each provided with current consuming apparatus. The box type transformer is used for acquiring electric energy from a power grid. The control unit is electrically connected with the miniature wind power generation equipment and the box type transformer. Under the normal condition, the miniature wind power generation equipment supplies electric energy to the current consuming apparatus. Under the condition that the miniature wind power generation equipment cannot supply electric energy, the box type transformer acquires electric energy from the power grid to meet the requirement of the current consuming apparatus.

Description

technical field [0001] The invention relates to wind power generation technology, in particular to a wind power generator. Background technique [0002] Wind power is one of the renewable energy sources, which is cheap, inexhaustible, inexhaustible and environmentally friendly. Wind turbines are the core equipment in wind power generation, and their main function is to convert wind energy into electrical energy. When the wind turbine converts wind energy into electrical energy, the equipment of the wind turbine itself also needs electrical energy (these devices are collectively referred to as power-consuming equipment) to ensure that the control system, yaw system, pitch system and safety chain of the wind turbine normal work. The wind power generator includes a tower tube fixedly arranged on the foundation and a nacelle cover arranged on the top of the tower tube, and the inner chamber of the tower tube and the nacelle cover communicates. Gear boxes and other equipment a...
