A superconducting magnet cooling system and control method

Abstract

The present invention discloses a superconducting magnet cooling system and a control method, wherein the superconducting magnet cooling system comprises a refrigeration unit, a superconducting magnet, a gas storage tank and a control unit, wherein the refrigeration unit is connected to the superconducting magnet to provide a working environment suitable for the superconducting magnet, the gas storage tank is connected to the refrigeration unit to store part of the refrigeration gas of the refrigeration unit, the control unit is connected to the superconducting magnet to monitor and adjust the pressure of the superconducting magnet, and the control unit is connected to the gas storage tank to control the storage and release of the gas in the gas storage tank. The control method adjusts the operation of the compressor through the gas storage tank according to the pressure of the superconducting magnet, so that the pressure of the superconducting magnet remains stable, and at the same time, the excess refrigeration capacity of the cooling system maintains a stable value, and the system can automatically adjust to reduce system energy consumption.
