Abstract

The invention discloses a full-automatic plug-in current lead device, belonging to the technical field of superconducting magnet cooling devices. The full-automatic plug-in current lead device comprises: a Dewar, which is internally provided with a fixed plug; a neck tube, wherein one end of the neck tube communicates with the interior of the Dewar, the other end of the neck tube is closed, a guide tube is arranged at the closed end, at least a part of the guide tube extends into the Dewar, and a first valve is arranged on the guide tube; an automatic plugging assembly, which comprises a current lead and a driving assembly, wherein the current lead can penetrate through the guide pipe to be connected with the fixed plug, and the driving assembly can drive the current lead to move in a direction close to or away from the fixed plug; an outer cover, wherein a sealed vacuum space is formed in the outer cover, and the automatic plugging assembly is located in the outer cover; and a controller, which can control a switch of the driving assembly. According to the automatic plugging assembly, automatic plugging of the current lead can be achieved, manual operation of workers is not needed any more, and the hidden danger that the current lead is frostbitten in a working process and poisoning is caused by operation in a closed chamber is eliminated.

Description

technical field [0001] The invention relates to the technical field of superconducting magnetic separation devices, in particular to a fully automatic plug-in current lead device. Background technique [0002] The current lead is an important external component of the superconducting magnet. It is a bridge connecting the external power supply and the superconducting coil when the superconducting magnet is excited. The current lead is usually composed of a fixed plug installed inside the superconducting magnet and a movable plug outside the superconducting magnet. It consists of two parts; usually, we refer to the movable plug on the outside of the superconducting magnet as the current lead. [0003] When the existing superconducting magnet is in the excitation operation, the staff needs to manually insert the current lead into the superconducting magnet from the outside. Since the inside of the superconducting magnet is filled with liquid helium and is in an extremely low te...
