摘要

The present invention relates to an oil supply apparatus and, more specifically, to an oil supply apparatus capable of supplying oil in an electrical method or a mechanical method depending on whether electricity is supplied. According to an embodiment of the present invention, the oil supply apparatus comprises: an electrical oil supply unit to supply oil to a gear box of a wind power generator; a mechanical oil supply unit to supply oil to the gear box by using rotary power of the gear box; and a switching unit which prevents the rotary power of the gear box from being transmitted to the mechanical oil supply unit if power is provided for the electrical oil supply unit, and controls the rotary power of the gear box to be transmitted to the mechanical oil supply unit if power is not provided for the electrical oil supply unit.
