Abstract

The invention discloses a fully automatic plug-in type current lead device, which belongs to the technical field of superconducting magnet cooling devices, and comprises: a Dewar with a fixed plug inside; a neck tube with one end communicating with the Dewar and the other end closed , a guide tube is provided on the closed end, at least part of the guide tube extends into the interior of the Dewar, and a first valve is provided on the guide tube; the automatic plug-in assembly includes a current lead and a drive component, and the current lead can pass through the guide tube and the The fixed plug is connected, and the driving component can drive the current lead to move in the direction close to or away from the fixed plug; the outer cover forms a sealed vacuum space inside, and the automatic plug-in component is located in the outer cover; the controller can control the switch of the driving component; the present invention The advanced automatic plug-in and pull-out components can realize the automatic plug-in and pull-out of the current leads, which no longer requires manual operation by the staff, eliminating the hidden dangers of frostbite during work and poisoning caused by operation in a closed room.

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...
