Embodiment 1

[0042] Such as figure 2 , image 3 As shown, this embodiment provides an enveloping high-speed dynamic wireless power supply system simulation experiment device, including an annular protection wall 1, an energy emission mechanism 2 detachably arranged along the circumference of the annular protection wall 1, and an energy emission mechanism 2 along the circumference of the annular protection wall. 1. A rotating mechanism 3 that rotates the central axis, a mounting frame 4 connected to the rotating mechanism 3, and an energy receiving mechanism 5 detachably arranged on the mounting frame 4;

[0043] Ring protection wall 1 can adopt brick wall or cement concrete wall, also can adopt wooden or other materials to make, and ring protection wall 1 can be used as the installation carrier of energy transmitting coil 21, can be used as the safety protection wall of experimental device again, prevents The high-speed operation of the equipment causes the equipment to break away and ca...

Embodiment 2

[0054] Such as Figure 4 and Figure 5 As shown, this embodiment provides a cage-type enveloping high-speed dynamic wireless power supply system simulation experiment device. The difference from Embodiment 1 mainly lies in the structure of the mounting frame 4 and the adjustment of the installation method of the energy receiving mechanism 5 and various sensors. Figure 4 and Figure 5 It can be seen that, in this example, the mounting frame 4 is a rotating disk arranged on the drive column of the direct drive motor. A plurality of energy receiving mechanisms 5 placed vertically are evenly distributed on the circumference of the outer wall, and voltage sensors, current sensors, temperature sensors and pressure sensors are installed on the surface of the rotating disk.

[0055] In this embodiment, two upper and lower discs are used to fix the vertically placed energy receiving coils, and the number of receiving coils can be increased or decreased according to actual experiment...

Description

technical field [0001] The invention relates to wireless power supply technology, in particular to an enveloping high-speed dynamic wireless power supply system simulation experiment device. Background technique [0002] Wireless power supply is a non-contact power supply method. It usually uses the principle of electromagnetic induction to transfer energy from the transmitter to the receiver. The transmitter converts the electrical energy into relay energy in the form of electromagnetic field energy. After a certain distance is transmitted through the air, Then the relay energy is converted into electrical energy through the receiving coil to realize the wireless transmission of electrical energy. [0003] Dynamic magnetic coupling resonance wireless power supply technology (hereinafter referred to as "dynamic wireless power supply technology"), as an extension of magnetic coupling resonance wireless power supply technology, is to realize the non-contact power supply of ele...
