Problems solved by technology

Among them, the permanent current leads remain inside the magnet no matter during the excitation or de-fielding process or after any operation is completed, so it is easy to generate additional heat conduction; while the temporary current leads are connected to the magnet during the energization and de-fielding process, but after the completion It is pulled out, so manual frequent plugging and unplugging are required during use, and the operation is complicated

[0065] Please see Figure 1-Figure 3 , the inner chamber includes a first inner chamber 7101a formed in the first power member 71 and a second inner chamber 7103a formed in the second power member 73, and the working medium includes the first working medium contained in the first inner chamber 7101a and the second working medium accommodated in the second inner chamber 7103a. The first inner cavity 7101a and the second inner cavity 7103a are connected to each other and arranged up and down along the reciprocating direction of the moving joint 30a, and both have a shared common wall 716, which is an elastic wall. The movable joint 30a is fixedly connected to the common wall 716, and follows the common wall 716 to reciprocate between the connected position and the disconnected position according to the force of the first working medium and the second working medium acting on the common wall 716 together. That is to say, the force acting on the power assembly is the sum of the f...

[0079] Please see Figure 4 , the power assembly formed by the first power member 71 is generally in the shape of a hollow frame, which includes an upper top wall 712 and two side walls 714 formed by extending the top and bottom ends of the upper top wall 712 toward the same direction. The upper top wall 712 is opposite to the superconducting magnet housing 400, the ends of the two side walls 714 away from the upper top wall 712 are fixedly connected to the superconducting magnet housing 400, and the common wall 716 is slidably connected up and down along the reciprocating direction of the moving joint 30b. Between the two side walls 714 , and the common wall 716 , the upper top wall 712 and the upper half of the two side walls 714 jointly define the first inner chamber 7101b.

[0080] The second power member 73 is a deforming part, which is deformably connected between the common wall 716 and the outer surface of the superconducting magnet housing 400 along the reciprocating ...

Abstract

The invention relates to a current lead structure and a superconducting magnet, comprising a fixed joint, a movable joint, a deformation seal assembly and a power control device. The power control device comprises a power assembly having an inner cavity filled with an acting medium; The power module drives the movable joint relative to the superconducting magnet shell to reciprocate between the connection position contacting with the fixed joint and the disconnection position separated from the fixed joint according to the acting force acting on the inner cavity by the acting medium itself ortogether with the external force, and the power module drives the movable joint to reciprocate between the connection position contacting with the fixed joint and the disconnection position separatedfrom the fixed joint. The current lead structure and the superconducting magnet provided by the present application move the connector to be connected with the fixed connector during excitation and field reduction. After the closed loop of the superconducting coil is completed, the moving joint is moved to be disconnected from the fixed joint; Considering the convenience of permanent current leadoperation and the advantage that no additional heat conduction is generated after the temporary current lead is pulled out. At that same time, a power control module is arranged in the current lead structure to automatically control the on-off of the movable joint and the fix joint, and the operation is convenient.

Description

technical field [0001] The invention relates to the technical field of superconducting magnets, in particular to a current lead structure and a superconducting magnet. Background technique [0002] Superconductivity refers to the property that the resistance of certain substances decreases to zero under certain temperature conditions (generally lower temperatures). The superconductivity of materials can be used to make superconducting magnets. Wherein, the superconducting coil in the superconducting magnet is conducted with an external circuit through a current lead to generate a magnetic field and store energy. [0003] However, there are two common types of current leads, permanent current leads and temporary current leads. Among them, the permanent current leads remain inside the magnet no matter during excitation or de-fielding or after any operation is completed, so are prone to additional heat conduction; while temporary current leads are connected to the magnet durin...
