It will be built up within 10 years futures.High-temperature superconductive lead wire is its huge cryogenic magnet power supply, while being the main heat of magnet
Load source.Since superconducting magnet and current feed itself work in low temperature, vacuum environment；And large-scale current feed weight
Up to hundred kilograms of magnitudes, the connecting flange of current feed and vacuum dewar allows for carrying weight itself；Current feed is superconduction
Magnet transmits electric current, and vacuum dewar is in ground state, and current feed allows for carrying the exhausted of volts up to ten thousand under fault case
Edge, thus can integrated high voltage insulation, intense loading lotus, the insulating flange that can be worked under vacuum and low temperature be to guarantee that current feed is normal
The key of safe operation.
Summary of the invention
The object of the present invention is to provide a kind of indoor temperature end insulating flanges for high current high-temperature superconductive lead wire, realize
Current feed transboundary vacuum connect with atmospheric environment, high pressure and earthing potential, connection room temperature and low temperature, while electric current can be carried
Lead weight load itself.

Both ends are tightly connected with end flanges and vacuum flange respectively, the sealing surface between insulating sleeve and end flanges, vacuum flange
Respectively by silicon rubber loop top tight sealing, installation process is simplified under the premise of guaranteeing vacuum sealing performance；The insulation sleeve
The outer solidification between end flanges, vacuum flange of cylinder has a circle flange insulating layer；Full skirt knot is welded on the end flanges
Structure, when current feed vertical state is run, umbrella skirt construction can effectively stop the condensed water from indoor temperature end to fall into high-low voltage method
Insulated outer surface between orchid, end flanges are welded on current feed main casing body, and vacuum flange and vacuum dewar sealing connect
It connects.
A kind of indoor temperature end insulating flange for high current high-temperature superconductive lead wire, it is characterised in that: described
Insulating sleeve outer surface vehicle has a screw thread, and flank smears epoxy glue, the end flanges, vacuum flange pass through respectively screw thread with
The connection of insulating sleeve both ends.
A kind of indoor temperature end insulating flange for high current high-temperature superconductive lead wire, it is characterised in that: described
The glass tape of flange insulating layer epoxy impregnation is wrapped and is suppressed it under vacuum conditions so that generating in wrapping
Bubble, which all discharges to carry out heating again to it, makes its solidification.
The present invention connects high pressure and earthing potential by the insulating sleeve of sufficient intensity, meets mechanical strength and insulation pressure resistance
Intensity；The separation of the atmosphere and Dewar vacuum of current feed is realized by screw thread and silicon rubber loop sealing structure；Pass through vacuum method
