Description
Technical field
The present invention is a kind of modular cold nested structure of sectional hyperconductive cable.
Background technique
High-temperature superconductive cable in order to reach high efficiency, it is low-loss lose purpose, using non-resistance superconductor make
For electric conductor.Hyperconductive cable can transmit high current, also have many advantages, such as small in size, light-weight.
High-temperature superconductive cable only has 0.5% transmission loss, much smaller than the loss of normal cable.With conventional electrical power cable phase
Than high-temperature superconductive cable has bigger current density, and 60% can be declined by being lost.Existingly with high-temperature superconductive cable transformation
Transmission line capability can not only be improved 3 times or more, and can reduce by 20% total cost by lower cable system.It is super by application high temperature
Cable can also change traditional power transmission mode, i.e., electric energy is transmitted by the way of low-voltage and high-current.Therefore, high-temperature superconductor electricity
Cable can greatly reduce loss of the electric system in electricity transmission process, improve the gross efficiency of electric system, have considerable economy
Benefit and environmental benefit.
But due to production and transportation etc., the length of current every hyperconductive cable is limited.Therefore exist
When being laid with the transmission line of electricity of long range, need to dock several hyperconductive cables in the construction site for being laid with cable.Traditional
Interconnection method is needed using techniques such as welding, rivetings.And the structure of hyperconductive cable is complex, cable core, cooling medium circuit
Equal component parts are all very fragile.When using current various technique connecting cables, not only need to add additional structure pair
Cable core and external other parts are attached respectively, at the same be also possible to because the careless manipulation in construction destroy cable core or
The more fragile structure such as cooling medium circuit.
In order to solve problem above, the present invention proposes a kind of modular cold nested structure of sectional hyperconductive cable.This
Structure can simplify the installation connection procedure of hyperconductive cable.
Summary of the invention
Cold nested structure of the present invention, including superconducting cable core, insulating layer, upper cold casing, under cold casing, cooling be situated between
Matter, vacuum layer, insulating layer.
The upper cold casing cold casing under is made of outer wall vacuum layer and insulating layer, and center is cavity, to pass through
Cooling medium, upper cold casing cold casing under are independently of each other, to be combined together by sliding slot, realize the cold noose of hyperconductive cable
The quick assembling of structure, meanwhile, upper cold casing both ends of cold casing under are provided with attachment device, it is convenient to connect phase
Two adjacent cables.
The cold nested structure of the hyperconductive cable have the characteristics that modularization, convenient for assembling, it is easy to disassemble.
Detailed description of the invention
Fig. 1 is the structure diagram of the cold nested structure of modularization sectional hyperconductive cable of the invention；
Fig. 2 is that the plan view for sharing sliding slot is matched in the upper cold casing of the invention cold casing installation under；
Fig. 3 is the structure diagram of two end connection device of cold nested structure of the invention.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiments of the present invention will be described in further detail.Following instance
For illustrating the present invention, but it is not intended to limit the scope of the invention.
As shown in Figure 1, the hyperconductive cable with the cold nested structure of sectional includes: hyperconductive cable cable core 1, insulating layer 2,
Upper cold casing 3, under cold casing 4, cooling medium 5, vacuum layer 6, insulating layer 7.Hyperconductive cable cable core 1 is at center, around by exhausted
Edge layer 2 is wrapped in.Upper cold casing 3 cold casing 4 under is combined together by sliding slot 8, by cable core 1 around firmly.In upper cold set
Pipe 3 is passed through cooling medium 5 in the cavity of cold casing 4 under, it is ensured that cable core works normally required temperature.Upper cold casing 3
The outer wall of cold casing 4 is made of vacuum layer 6 and insulating layer 7 under, guarantees the temperature of cooling medium 5.
As shown in Fig. 2, upper cold casing 3 and under sliding slot 8 between cold casing 4.Upper cold casing 3 cold casing 4 under is mutually only
It is vertical, it is combined together in assembling by sliding slot 8, limits radial movement.
As shown in figure 3, upper cold casing 3 both ends of cold casing 4 under are provided with attachment device 9.When connecting two cables,
The edge of two opposite attachment devices of cable 9 is blocked with limiter 10, while there are two groove 11 in attachment device 9,
To add sealing material, the exposing for having cooling medium in junction is prevented.10 end 12 of limiter is fixed with bolt.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
