Embodiment 1

[0064] The space system operates in low-earth orbit, and the revolution and rotation planes coincide, both on the geomagnetic equatorial plane. There is a battery device at the center of mass 3, two connecting ropes 4 are 10km long, and superconducting cables 1 are each 6,000 meters long. 3 tons, the maximum allowable current is 7000A, and can generate an average thrust of 1000N.

[0065] Superconducting cables do not rely on refrigerants to maintain low temperature during operation, but rely on cold storage layers and other substances to absorb heat, reduce temperature rise, and ensure that the temperature of superconductor strands is not higher than the transition temperature during operation.

[0066] The innermost layer of the superconducting cable 1 is a superconductor stranded wire, which is made of bi-2223 superconducting tape, with a diameter of 14mm. There are 3 layers of multi-layer heat insulation layers 22, 2 cold storage layers 21, and each stranded wire The layer...

Embodiment 2

[0071] The superconducting cable 1 has no capillary, and the others are the same as in the first embodiment. The superconducting cable 1 is put into the liquid nitrogen pool and cooled slowly by liquid nitrogen. Refrigerant fluid flows through the gaps to achieve cooling.

Embodiment 3

[0073] The retracting device is composed of a fixed winch 6 and an electric winch. The fixed winch 6 is fixed at the center of mass 3. The winch rope 7 is suspended from the movable winch 8. The reel of the movable winch 8 is wound with a superconducting cable 1. The number of winding layers of the cable 1 generally does not exceed 3 layers, and the motors of the fixed / movable winch 8 all adopt servo motors.

[0074] The wire end of the superconducting cable 1 is bound at the center of mass 3, the fixed winch 6 releases the winch rope 7, the movable winch 8 moves outward under the action of centrifugal force, and at the same time the movable winch 8 releases the superconducting cable 1, so that the superconducting cable 1 can be released. The cable 1 becomes a straight line. One end of the superconducting cable 1 is tied at the center of mass 3, and the other end is at the movable winch 8. The speed at which the winch rope 7 is released is equal to the speed at which the cable ...

Abstract

A superconductive cable belongs to that technical field of superconduct cables, tethered satellites in space research use electric ropes to produce several newtons of thrust, the MXER system uses electric ropes to restore revolution speed, the invention provides a superconducting cable for space, to keep the superconducting cable low temperature by means of cold storage, and electric thrusters togenerate powerful currents, the current that drives a superconducting cable with a battery, Get the thrust in the direction of the revolution, increasing or decreasing the speed of revolution of the system, take advantage of this technical solution, hundreds of newtons of thrust can be obtained, The invention solves the problem that the temperature of the superconducting cable is too high, reducesthe weight and the cost of the superconducting cable, and ensures that the superconducting cable can quickly return to the original speed after the work is finished. The invention is characterized inthat the superconducting cable is provided with an interface for circulating the refrigerant at a distance, and the thin tube is assembled at the interface.

Description

technical field [0001] The invention relates to the technical field of superconducting cables, in particular to a superconducting cable. Background technique [0002] Ordinary rockets need to accelerate the spacecraft to the first cosmic speed of 7.7km / s or more before it can be sent into space orbit. The cost per ton of launch is between 8-30 million US dollars on average, which is very high, and the volume and weight of the rocket are large , technically complex. [0003] Foreign experts proposed a system (MXER system) for capturing and ejecting loads by electric propulsion ropes. See page 201 of the book "Introduction to Rocket Formation Flight". The electrons in the ionosphere generate current, and the ampere effect is generated by the electric rope in the geomagnetism to generate an ampere force, which increases the revolution speed of the system, and collecting electrons is very inefficient, and the current formed is only a few A, and the electric thrust formed is onl...
