Description
Technical Field
The invention relates to the technical field, in particular to a production process for winding operation.
Background
In a magnetic levitation track traffic system, zero-flux coils are also called splayed coils, the zero-flux coils provide levitation force and guiding force for a train, and the zero-flux coils arranged on two sides of a track beam are connected through hinge lines. When the train is laterally offset, the current in the hinge line is correspondingly changed due to the change of the current in the zero-flux coils at the two sides of the track, so that the guiding rigidity of the zero-flux coils is changed, and the train is always kept at the center position of the zero-flux coils at the two sides of the track.
For a zero-flux coil operating in a vacuum environment, when there is a zero-flux coil swept by the superconducting magnet, the zero-flux coil may also generate heat due to its own material properties after normal operation. In a vacuum environment, the heat of the zero-flux coil is difficult to dissipate, and the zero-flux coil shell (usually cast by epoxy resin) can age and lose effect over time, so that the zero-flux coil cannot work normally.
The hinge heads are arranged between the current zero-magnetic-flux coil and the hinge line and are used for connecting the zero-magnetic-flux coil and the hinge line, one end of each hinge head is connected with the middle part of the zero-magnetic-flux coil, the other end of each hinge head is connected with the hinge line to form two connecting joints, and the joint connection mode of each hinge head and each zero-magnetic-flux coil can directly influence the heating condition of the zero-magnetic-flux coil; the existing hinge head and the zero-magnetic-flux coil are generally connected by welding, riveting or bolting. However, the resistance of the joint in the welding mode is larger, the temperature rise of the joint is fastest when the zero-flux coil works normally, and the ageing of the shell material of the joint is fastest, so that the service life of the zero-flux coil is further shortened. The joint of riveting or bolting also has larger contact resistance, so that the temperature rise of the joint is fastest, and the ageing of the shell material of the joint is fastest, thereby further shortening the service life of the zero-flux coil.
