Non-contact power supply device for axle load electronic equipment in rotator

Abstract

The invention discloses a non-contact power supply device for an axle load electronic equipment in a rotator. The non-contact power supply device comprises a transmitting terminal, a transmitting coil, a transmitting resonant capacitor, a receiving coil, a receiving resonant capacitor and a receiving terminal, wherein the transmitting terminal is used for receiving commercial power and converting a commercial AC signal into a high-frequency AC signal; the transmitting coil and the transmitting resonant capacitor are connected in parallel, connected with the transmitting terminal and used for transmitting the high-frequency AC signal; the receiving coil and the receiving resonant capacitor are connected in parallel and used for receiving the high-frequency AC signal; the receiving terminal is connected with the receiving coil and the receiving resonant capacitor and used for converting the high-frequency AC signal into a current signal required by the load of the electronic equipment; and the transmitting coil and the receiving coil are coupled with each other. The non-contact power supply device can achieve high-power transmission through receiving and converting the commercial power, and realizes transmitting power supply with higher efficiency through resonance of both transmission elements and receiving elements.

Description

technical field [0001] The invention relates to a wireless power supply system, in particular to a non-contact power supply device for electronic equipment mounted on a shaft of a rotating body. Background technique [0002] In actual production and life, electric energy is an indispensable resource, and the acquisition of electric energy is generally obtained through wired connection contact, so the transmission of electric energy has certain limitations. In some special environments, such as when powering electronic equipment inside a rotating shaft-loaded object, power can be supplied by contact (such as a brush) when the site environment is good. However, in harsh environments such as high ambient humidity and large dust, the contact power supply method may generate sparks, making the power supply unstable or even dangerous, and this will also generate a certain amount of friction, which will affect the rotating equipment, while the wired power supply method Obviously i...
