System for limiting a peak current of short-circuit current

A system for limiting a peak current of short-circuit current, comprising:

• a first high-frequency branch, configured to provide a first high-frequency current to a first switch (1SKa) of a first phase branch of a three-phase AC when the first phase branch occurs a short-circuit, wherein the first high-frequency current is configured to cause a zero-crossing point of a short-circuit current to appear before a zero-crossing point of the three-phase AC;
• a second high-frequency branch, configured to provide a second high-frequency current to a second switch (1SKc) of a second phase branch of the three-phase AC when the second phase branch occurs a short-circuit, wherein the second high-frequency current is configured to cause a zero-crossing point of a short-circuit current to appear before a zero-crossing point of the three-phase AC;
• a third phase branch of the three-phase AC, connected in parallel with the first phase branch and the second phase branch, and configured to always supply power;
• and
• a plurality of cabinets, in which a first cabinet is arranged with the first high-frequency branch, a second cabinet is arranged with the second high-frequency branch, and a third cabinet is arranged with the first phase branch, the second phase branch and the third phase branch, wherein the third phase branch is arranged in the middle of the first phase branch and the second phase branch.
