Specific embodiment
With reference to the accompanying drawing and specific embodiment further illustrates the present invention.
A kind of adjustable magnetic fields generating device for the constraint of space magnetic reconnection, by the circle for changing every cake coil access
Number, thus it is possible to vary single cake coil connects the number of ampere turns into power supply, to change the distribution in magnetic field；
Wherein, it after every cake coil all passes through coiling, is poured and is fixed by insulating resin, while be provided with right above coil
It having more hole slot and respectively corresponds every circle coil for external impressed current lead, the fixation with coil of current feed is fixed by bolts,
Simultaneously at the hole slot for not needing connection current feed, covered using insulating resin.
Wherein, the current feed between every two cakes coil is formed using the metal current connection of package magnetic shielding material,
For convenience with the length of change current connection, the position that can be connected according to every two cakes coil increase or decrease connector
Length, thus adapt to the spacing variation of the current feed between every two cakes coil.
Magnetically confined device in Magnetic Reconnection experiment, is arranged by building around vacuum chamber by more cake coils
Magnetic confinement coil form.The specification of every cake magnetic confinement coil is consistent, and using same material, same winding method has
Identical the number of turns.
Magnetically confined coil uses concatenated form, and the positive and negative anodes connecting lead wire of every cake coil is all located at the top of coil,
And guarantee that the axial centre of coil and the center of vacuum chamber are located in same horizontal line, the lead and power supply of two coils of outermost

It is used to ensure the stability of current connection due to the bracket that top is installed.Current connection is wrapped using magnetic shielding material
It wraps up in, the magnetic field that can effectively inhibit electric current connecting line to generate.
After every plate coil coiling, formed by poured with epoxy resin fixation, every circle coil does not contact with each other.Coil just on
Fang Jinhang fluting simultaneously installs metal connecting piece in the top of every circle coil, and is equipped with bolt, draws for fixing and connecting electric current
The both ends of line.
The needs of intensity and bit-type occur according to magnetic field, the magnetic field the number of turns for entering circuit is connected in series in selection, and by place
Current connection is connected after the coil connection current feed of the number of turns, then selection with epoxy resin lid carries out it for remaining coil
Capping.
Due to the difference of the concatenated current lead placement of coil, the design that selection is split at the middle part of current connection can
With the extension current connection for connecting different length.In order to keep the effect of connection, in the design of the surface of each connector,
The design of metallic connection parts position keeps certain thickness protrusion, guarantees the laminating degree on surface, reduces contact resistance, in this way can be with
The electric current of two connection surfaces is promoted to transmit.
The structure design of single cake magnetic coil is transformed by the design of the field generator for magnetic constrained magnetic reconnection in the present invention,
Increase for changing the connection member for connecting magnetic coil the number of turns into circuit, can guarantee same current-series in whole magnetic coil
In the case where, by changing the number of ampere turns of every cake coil to change whole Distribution of Magnetic Field.
