JPH10146074A - Superconducting dc power generator - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a superconducting DC power generator consisting of coil in the magnetic field which can generate DC electrical power and assure extremely high efficiency, even when a relative movement of the coil is not effected in the magnetic field. SOLUTION: In a superconducting DC power generator, a superconducting coil 5 winding up to the center having an output electrode 4 is fixed with a non-magnetic coil fixing tool 7, in the field provided between N pole 2 and S pole 3 of a permanent magnet 1 provided at the internal side of an iron plate 6 of a ferromagnetic material. With the structure explained above, since the rotating motion energy for power generation is no longer required, the power generation efficiency is extremely high.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a superconducting DC generator capable of generating DC power without a relative movement between a magnetic field and a coil and having extremely high power generation efficiency.

[0002]

2. Description of the Related Art A conventional generator using a magnetic field and a coil cannot generate power unless there is a relative movement between the magnetic field and the coil due to rotational motion.

[0003]

This has the following disadvantages. For power generation, a large amount of energy was required to make the rotating motion, and the power generation efficiency was very poor. The present invention has been made to eliminate this disadvantage.

[0004]

In the magnetic field between the north pole (2) and the south pole (3) of the permanent magnet (1), a superconducting coil (5) wound around the center having the output electrode (4) is provided. A superconducting DC generator.

[0005]

[Function] Due to the unique diamagnetism that eddy current flows so that magnetic flux does not enter the superconductor even if there is no change in magnetic flux, power generation continues even without physical rotation.
DC power can be obtained from the output electrode (4).

[0006]

Embodiments of the present invention will be described below. As shown in FIG. 1, the permanent magnet (1) provided inside the ferromagnetic iron plate (6) is wound into the magnetic field between the N pole (2) and the S pole (3) up to the center having the output electrode (4). Superconducting coil (5)
Is fixed by a non-magnetic coil fixing device (7). With such a configuration, DC power is obtained from the output electrode (4). The same effect can be obtained by winding the superconducting coil (5) around the cylindrical superconductor (8) as shown in FIG. The same effect can be obtained by using a superconducting electromagnet instead of ()).

[0007]

The power generation efficiency is extremely high because no rotational kinetic energy is required for power generation.
