Title:
SUPERCONDUCTING MAGNET SYSTEM AND QUENCH PROTECTION CIRCUIT THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/166004
Kind Code:
A1
Abstract:
Disclosed in the present invention are a superconducting magnet system and a quench protection circuit therefor. The quench protection circuit comprises: a superconducting unit, a first diode integrated component, a second diode integrated component, a third diode integrated component, a low-temperature superconducting switch, a thermal radiation layer, and a vacuum layer; the superconducting unit consists of M superconducting coils connected in series; one end of the low-temperature superconducting switch is connected to a non-series connection end of the first superconducting coil, and the other end is connected to a non-series connection end of the M-th superconducting coil; the first diode integrated component is connected in parallel to the low-temperature superconducting switch; the thermal radiation layer and the second diode integrated component are connected in series and then connected in parallel at two ends of any symmetric coil subset in the superconducting unit; the vacuum layer and the third diode integrated component are connected in series and then connected in parallel at two ends of any symmetric coil subset of the superconducting unit. According to the present invention, the thermal radiation layer and the vacuum layer are utilized to protect the superconducting magnet system from damage during a quench period, and reduce cooling time of a superconducting magnet and liquid helium loss.
