Let H C be the critical magnetic field of the superconductor 1. The normal magnetic field source 2 is a permanent magnet or a superconducting magnet, and its magnetic field is now H 2 =

０，１ＨＣから＋０，０５ＨＣの間では、超電導体１は
超電導状態にある。そのためThe magnetic field H 3 of the fluctuating magnetic field source is
The superconductor 1 is in a superconducting state between 0,1H C and + 0,05H C. for that reason

急激に常電導状態になる。その結果、FIG. 1 shows the normal magnetic field source 2 by the Meissner effect as shown in FIG.
The magnetic field received by the induction coil 5 is 0 because it shields the magnetic flux. When H 3 exceeds +0.05 H C , the magnetic field (H 2 + H 3 ) received by the superconductor 1 exceeds H C , and the superconductor 1 rapidly enters the normal conducting state. as a result,

When the magnetic field of the fluctuating magnetic field source 3 decreases from the maximum value + 0,1H C to + 0,05H C or less, the Meissner effect appears again in the superconductor 1 and the magnetic fluxes of the ordinary magnetic field source 2 and the fluctuating magnetic field source 3 Shielded. At this time, the induction coil 5

If either or both of the induction coils 5 can be wound at the same time, the power generation equipment can be further downsized. Also,

Further, since the second type superconductor has a high critical magnetic field, if a second type superconductor is developed in which the upper critical magnetic field and the lower critical magnetic field are very close to each other in the future, the electromotive force will be larger.

どの利点は、低出力の欠点を補って余りあるであろう。[Fig. 2] When the electric current J is generated in the induction coil 5 as shown in Fig. 2, that is, when the electric power that can be used by us is taken out, the electric power required for the fluctuating magnetic field source 3 is the fluctuation of the magnetic field of 0 → ± 0, 1H C. Is required. By electromagnetic induction when doing. Therefore, assuming that the electric power that can be obtained by the induction coil 5 is 100, the electric power required for the variable magnetic field source 3 will be 10. Then, when 10 electric powers are recovered from the induced electromotive force of 100 to the fluctuating magnetic field source 3, the remaining 90 is energy that can be used as an output. Even if the circuit loss and the power required for cooling are taken into consideration, 80
Energy will be available as output from the load resistor 6. Actually, considering how much electric power can be obtained in the case of niobium which is a first-type superconductor as a material of the superconductor 1, the critical magnetic field is 0,2 Tesla. On the other hand, the normal superconducting generator currently prototyped is said to have an output of 70,000 kw with a superconducting electromagnet of 5 Tesla. Therefore, a simple comparison shows that the generator of the present invention has an output of about 2200 kw. Become. From 100,000 kW to 10
Compared to the existing generator of 0,000 kW class, the output is small,
A single generator does not provide a large-scale power source. However, the advantage of not requiring external energy supply and the need for large-scale equipment such as dams, steam generators, turbines, etc. would be more than enough to compensate for the drawback of low output.
