The invention discloses a superconductive generator current phase changer used for the transmission of magnetic pole of a superconducting magnet and the current phase change of a superconductive generator thereof, comprising an electric brush, a lead, an insulator, a rotating shaft and a shell; the invention is characterized in that a phase change device which is arranged on the surface of the insulator; the phase change device consist of copper sheets, copper rings and a lead; wherein, the copper sheets are arranged on the insulator, and the direction of the copper sheets are in parallel to the copper rings; the copper sheets are arranged on the insulator and are at the same straight line with other copper sheets, and the copper sheets are connected with the copper rings by the lead, so that after the rotating shaft rotates 180 degrees, the electric brush is in contact with the copper sheets in a friction way. Compared with the traditional generator current phase change switch, the current phase change can be carried out continuously; the rotating frequency can be changed according to the current magnitude, so that the phase change is carried out on the current under the same frequency.
Description
technical field [0001] The invention relates to a commutation method, in particular to a superconducting motor current commutator, which is used for switching the magnetic poles of a superconducting magnet and commutating the current of a superconducting generator. Background technique [0002] Superconducting technology can make generators and motors miniaturized, with more powerful power and more stable working performance, so as to replace the current large and heavy power generation facilities, and also provide the possibility of low noise and military use of motors. All countries are developing superconducting generators, but the development of superconducting coils installed on the rotating body is the key to research. In the past, there are many deficiencies in the phase-changing equipment. For example, in industrial production, the structure of the traditional phase-changing equipment is complex, and problems cannot be repaired and maintained quickly; the production ...
