The rotor part and the stator part of the miniature slip ring are connected through a slideway instead of a cable, and similar to the slip ring of the CT rotor part, when the miniature rotor part rotates, the rotor and the stator part can still provide reliable electrical connection. The structure of the micro slip ring is the prior art, and the micro slip ring used in the present embodiment is a commercially available mofon MT series slip ring.
A cross-shaped fixing rod is fixed at one end of the stator part, a second connecting piece is installed on the CT stator, a positioning frame is arranged at one end of the second connecting piece, the positioning frame comprises four positioning legs, and each positioning leg is provided with a positioning hole; and each shaft lever of the cross fixing rod is respectively arranged in corresponding positioning holes of the four positioning feet. The cross-shaped fixed rod is sleeved with a spring and then is arranged on the positioning frame, the clearance a between the cross-shaped fixed rod and the positioning frame ensures the adjustment amount when the CT rotor and the center of the micro slip ring have small concentricity deviation, and the spring ensures that the cross-shaped fixed rod and the positioning frame have buffer force and restoring force when rotating. As shown in fig. 4, when the CT rotor and the micro slip ring are eccentric during rotation, the gap a between the cross bar and the positioning frame is fixed to ensure the relative movement of the micro slip ring during the eccentricity S, thereby compensating for the eccentricity S in fig. 4.

During installation, the micro slip ring is installed on the first connecting piece, and meanwhile, the first connecting piece is fixed on the CT rotor, and at the moment, the micro slip ring and the CT rotor are basically concentric.
The second connecting piece is not rigidly connected with the cross-shaped fixed rod, but four shaft levers of the cross-shaped fixed rod pass through the springs and penetrate through four positioning holes (round holes) on the positioning frame, and as shown in fig. 3, an automatic aligning structure is formed. When the center of the CT rotor and the center of the micro slip ring have small concentricity deviation, the CT rotor can still be automatically adjusted to work normally.
