Abstract
The utility model discloses a kind of cold exhausted hyperconductive cable termination, comprise current feed, termination, insulated tube, insulating sleeve, liquid nitrogen, thermostat, also comprise bellows, described thermostat comprises: the first casing, the second casing, tube connector, lead outlet.The cold exhausted hyperconductive cable termination of the one that the utility model provides, reduces the distance between tube connector and termination, nitrogen region is communicated with by narrow and small tube connector with liquid nitrogen regions, effectively can reduce heat output.Tube connector caliber narrow and small in addition, even if liquid nitrogen pressure changes, liquid nitrogen liquid level also can remain in the second casing.The use of bellows decreases the heat conducted by tube connector, further ensures the effect shortening tube connector.
Description
Technical field
The utility model relates to a kind of cold exhausted hyperconductive cable termination, belongs to hyperconductive cable manufacturing technology field.
Background technology
Cold insulation hyperconductive cable termination and normal temperature dielectric superconducting cable structurally have very large difference.The current feed of cold insulation superconducting cable conductor all will ensure good telegram insulation in thermostat or in atmospheric environment.Although the liquid nitrogen in cable is generally in supercooled state, still can form a liquid nitrogen blind area on the top of thermostat, the medium in blind area is nitrogen.Because nitrogen gas insulating effect is far smaller than liquid nitrogen, how shortening the transmission range of the section of nitrogen, is the problem that this area needs to solve.
Utility model content
Object: in order to overcome the deficiencies in the prior art, the utility model provides a kind of cold exhausted hyperconductive cable termination.
Technical scheme: for solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of cold exhausted hyperconductive cable termination, comprise current feed, termination, insulated tube, insulating sleeve, liquid nitrogen, thermostat, also comprise bellows, described thermostat comprises: the first casing, the second casing, tube connector, lead outlet, described second casing is set to cube structure, second box top is provided with tube connector, and described tube connector diameter dimension accounts for 1/8 of the second box top length; Liquid nitrogen is provided with in described second casing; Described tube connector end is socketed with bellows; Second casing, tube connector, bellows are all socketed in wherein by described first casing; Described first casing and the second casing offer the lead outlet be connected, and described first casing top is provided with insulating sleeve; Described current feed comprises longitudinally lead-in wire and horizontal lead-in wire, and longitudinally lead-in wire penetrates bellows from insulating sleeve, is connected in the second casing through tube connector by termination with horizontal lead-in wire; Longitudinal direction lead-in wire between described bellows to termination is socketed with insulated tube.
Also comprise access hole, described access hole is arranged on the side of the first casing.
Described insulated tube adopts epoxy resin material.
Ceramic insulation full skirt is also provided with outside described insulating sleeve.
Preferably, also comprise into liquid nitrogen pipe, described in enter liquid nitrogen pipe through the first casing, vertical insert the second box top.
Preferably, also comprise denitrogen tracheae, described denitrogen tracheae is through the first casing, and level inserts bellows side.
Beneficial effect: the cold exhausted hyperconductive cable termination of the one that the utility model provides, reduces the distance between tube connector and termination, nitrogen region is communicated with by narrow and small tube connector with liquid nitrogen regions, effectively can reduce heat output.Tube connector caliber narrow and small in addition, even if liquid nitrogen pressure changes, liquid nitrogen liquid level also can remain in the second casing.The use of bellows decreases the heat conducted by tube connector, further ensures the effect shortening tube connector.
