Description

Technical Field

[0001] The utility model relates to the technical field of non-contact slip rings, in particular to a power signal induction output non-contact slip ring. Background Art

[0002] The contactless slip ring uses a contactless transformer with completely separated primary and secondary sides to transmit electrical energy through the coupling of magnetic fields, so that there is no physical connection between the power supply side and the power consumption side during the energy transfer process. Compared with traditional contact mechanical slip rings, the contactless slip ring fundamentally solves the problem of mechanical wear. The "non-contact" of the slip ring makes its functions more diversified. It can not only undertake simple electrical connection functions, but also realize electrical isolation and power conversion functions.

[0003] A mechanical and non-contact composite slip ring with application number 201620161757.3 belongs to the field of power transmission and power conversion. When the system is operating normally, the stator moves toward the non-contact slip ring rotor side to maintain the optimal working gap between the two, and is open-circuited with the mechanical slip ring rotor. At this time, the electric energy is transmitted through the non-contact slip ring; when the non-contact slip ring fails, the auxiliary power device applies force to the stator to make the stator separate from the non-contact slip ring rotor and move toward the mechanical slip ring rotor side, so that the brush of the composite stator contacts the collector ring of the mechanical slip ring rotor. At this time, the electric energy is transmitted through the mechanical slip ring; when the non-contact slip ring returns to normal, the stator switches back to the non-contact slip ring side in the above manner.

[0004] However, in the implementation of relevant technologies, it was found that the above-mentioned mechanical and non-contact composite slip ring has the following problems: this device cannot adjust the working gap between the stator and the non-contact slip ring rotor during operation, so that the optimal working gap between the two cannot be maintained, and this device cannot cool the stator and the non-contact slip ring rotor. If the operating temperature of the composite stator and non-contact slip ring rotor is too high, the stator and non-contact slip ring rotor may be demagnetized, thereby preventing the device from outputting normally.
