A testing device for a current-carrying friction and wear performance of a flexible rolling friction pair, including a base plate, supporting profiles, and guiding rail sliders, and a screw assembly, and a movable supporting plate, and a fixed supporting plate, and first bearing supports, and a slider supporting plate, during the testing process, friction moment and friction force of the flexible rolling electrical contact component can be obtained by monitoring dynamic torque of rotating wheel, which is wide applicability, which allows simultaneous online monitoring of multiple experimental variables such as friction performance, current-carrying capacity, preload, friction force, and temperature; and at the same time, there is no need to adjust, assemble, or test multiple objects for the rolling ring structure; the testing process can be completed by only adjusting and testing the key electrical contact test piece, significantly simplifying the testing structure and method while reducing testing costs.

A distributed demagnetizing coil system, a shielding device, and a demagnetizing method. The system includes turns of demagnetizing coils evenly wound on each shielding surface of a shielding body in the shielding device at intervals and connecting wires provided on outer side of the shielding surface in an inflection manner. One half of each turn is located on inner side of the wound shielding body and the other half of each turn s located on outer side of the wound shielding body for providing corresponding demagnetizing magnetic fields to form a closed magnetic flux loop. One half of each connecting wire is connected to the corresponding demagnetizing coil, the other half of each connecting wire is reversely inflected along an original path and is connected to a power supply module, so that corresponding demagnetizing current is introduced into each demagnetizing coil connected to the connecting wire.
