Wireless Power Supply Device and Electrical Equipment

An electrical equipment, comprising:

• a carrier capable of being mounted at a plurality of different positions on an electrical equipment and having a load;
• and
• a wireless power supply device adapted to supply power to the load, including:
• a plurality of transmitting coil assemblies mounted at the plurality of different positions of the electrical equipment, each of the transmitting coil assemblies having a transmitting coil and a first magnetic core;
• a plurality of control switches disposed at the plurality of different positions and configured to switch on and off the transmitting coils of the plurality of transmitting coil assemblies;
• and
• a single receiving coil assembly mounted on the carrier and having a single receiving coil and a single second magnetic core, the transmitting coil mounted at one position of the plurality of different positions is disconnected by switching off the control switch provided at the one position before the carrier is mounted at one position, and the transmitting coil mounted at the one position of the plurality of different positions is connected by switching on the control switch provided at the one position after the carrier is mounted at the one position, such that the single receiving coil is electromagnetically coupled with the transmitting coil at the one position.
