| description | The invention discloses a zero-loss deep current limiting method and a current limiting system. The current limiting system comprises a ZXB current limiting device, an equipment monitoring unit, a monitoring analysis unit, an exception handling unit, a maintenance acquisition unit, a maintenance evaluation unit, an environment monitoring unit, an environment evaluation unit, an equipment image acquisition unit and an equipment image analysis unit. The ZXB current limiting device comprises a current converter, a current limiting reactor and a control device; when the system operates normally, the fast converter is in a closed state, the current limiting reactor is short-circuited, the active and reactive power loss of the reactor is zero, the ZXB current limiting device is in a low-impedance zero-loss state, and the control device does not operate; when the line or other equipment is short-circuited, the ZXB current limiting device controls the quick current converter to be switched off, and the deep current l |
