Abstract
The utility model discloses a kind of modified model cold insulation hyperconductive cable termination, comprise insulating sleeve, it is characterized in that: also comprise termination thermostat, bellows and current feed, liquid nitrogen is contained with in the thermostat of described termination, described termination thermostat is connected with insulating sleeve by passage, described passage interlude adopts bellows to substitute, nitrogen region is left in bellows, described current feed is through passage, below liquid nitrogen liquid level is stretched in one end of described current feed, and the other end of described current feed stretches in insulating sleeve.The utility model provides a kind of shortening termination height, ensures nitrogen temperature smooth transition, reduces the modified model cold insulation hyperconductive cable termination of energy loss when termination is run.
Description
Technical field
The utility model relates to a kind of hyperconductive cable termination, particularly relates to a kind of modified model cold insulation hyperconductive cable termination.
Background technology
Current hyperconductive cable termination, does not have enough distances between liquid nitrogen regions liquid level and insulating sleeve, and thermostat metal inner surface heat conduction is larger, the gentle transition of nitrogen temperature in cable socket cannot be ensured, when causing termination to be run, energy consumption is higher, and result of use is poor, and useful life is shorter.
Utility model content
In order to solve hyperconductive cable termination in prior art, enough distances are not had between liquid nitrogen regions liquid level and insulating sleeve, thermostat metal inner surface heat conduction is larger, cannot ensure the gentle transition of nitrogen temperature in cable socket, when causing termination to be run, energy consumption is higher, and result of use is poor, the problem that useful life is shorter, the utility model provides a kind of shortening termination height, ensures nitrogen temperature smooth transition, reduces the modified model cold insulation hyperconductive cable termination of energy loss when termination is run.
In order to solve the problem, technical solution adopted in the utility model is:
A kind of modified model cold insulation hyperconductive cable termination, comprise insulating sleeve, it is characterized in that: also comprise termination thermostat, bellows and current feed, be contained with liquid nitrogen in the thermostat of described termination, described termination thermostat is connected with insulating sleeve by passage, and described passage interlude adopts bellows to substitute, nitrogen region is left in bellows, described current feed is through passage, and below liquid nitrogen liquid level is stretched in one end of described current feed, and the other end of described current feed stretches in insulating sleeve.
Aforesaid a kind of modified model cold insulation hyperconductive cable termination, is characterized in that: described insulating sleeve adopts epoxide resin material to make.
Aforesaid a kind of modified model cold insulation hyperconductive cable termination, is characterized in that: described current feed adopts copper cash.
Aforesaid a kind of modified model cold insulation hyperconductive cable termination, is characterized in that: described insulating sleeve adopts elastomeric material to make.
Aforesaid a kind of modified model cold insulation hyperconductive cable termination, is characterized in that: described passage adopts Vertical Channel.
Aforesaid a kind of modified model cold insulation hyperconductive cable termination, is characterized in that: described channel vertical stretches into below liquid nitrogen liquid level.
The beneficial effect that the utility model reaches: the utility model modified model cold insulation hyperconductive cable termination, described termination thermostat is connected with insulating sleeve by passage, narrow and small channel connection is passed through in nitrogen region and liquid nitrogen regions, the heat output that nitrogen and liquid nitrogen pass through passage is very little, even if liquid nitrogen pressure changes, liquid nitrogen liquid level also can remain in passage, and channel middle has made bellows into simultaneously, for reducing the heat of thermostat conduction.The utility model modified model cold insulation hyperconductive cable termination not only better can ensure temperature transition, and by reducing the hot energy loss reduced when termination is run of leakage along insulating sleeve, also shortens the height of termination.
Accompanying drawing explanation
Fig. 1 is the utility model modified model cold insulation hyperconductive cable end structure schematic diagram.
Embodiment
