Abstract

PURPOSE:To reduce the leakage of magnetic flux, to prevent the heating of wall and to contrive miniaturization of a reactor device by a method wherein a pair of two coils are formed in such a manner that the magnetomotive force generating on each coil will be cancelled with each other. CONSTITUTION:A hollow core type reactor 13 is formed with series-connected air-core coils 14 and 15. The coils 14 and 15 are separately arranged so that the magnetomotive forces F11 and F12 generated by a passing current 'I' are cancelled with each other. In the reactor 13, magnetic flux PHI is present only in the vicinity of the coils 14 and 15, and no leakage magnetic flux is present around the reactor 13. Even when a container 3a is brought close to the reactor 13, the wall of the container is not heated up. As a result, the reactor device 16 can be made small in size.

[Problem that the invention seeks to solve]

In FIG. 7, the 'IX, I + accelerator device 4 is configured as described above and the temperature is ℃, so if the electric current is a high frequency current and the container wall 3a is near the reactor 2, the container wall has a permeability of If the reactor 2 is made of isoelectric material with a small magnitude, the magnetic flux Φ due to the magnetomotive force F1 of the reactor 2 interlinks with the container wall 3scK, and the resulting eddy current heats the container wall 31. Also.

In Figure 8, C is the temperature at which the magnetomotive forces F and F are added together, so the density due to these magnetomotive forces is
The gap 12a between the central legs 5a and 6a is wide (Natsu ℃), and the gap 12a between each outer leg 5b, 6b of the iron core 5.6 is wide.
gap 12c between the other outer legs 5c and 6a of the iron core 5.6
However, in the case of Figure 8, +i
Ft and F.

Since the reactor 9+ is formed as a single bar magnet with a magnetomotive force of (Ft→Fs), as a result, the outer periphery of the reactor 9 has Φt.
The leakage magnetic flux shown in is generated. However, a container wall 10a made of a dielectric material with a not small transmittance is provided where the bundle Φt of ``C, ff1'' is present.

If the magnetic flux Φt is based on a high-frequency electric current,
The container wall tOa is heated in the same manner as in the case of the reactor device 4.

When the vessel walls 3a and 101 are heated as described above in the reactor devices 4 and II, the electric power spent on this heating is lost as a loss from the electric power applied to the reactor 2.9. , as mentioned above or Akudol 2
．． 9, in order to reduce power loss, the container wall 3as
It is necessary to move the toa away from the accelerator, and for this reason, the reactor device ii4. There is a problem that lI becomes large. In addition, in the reactor 2.9, the size of the reactor device 4゜11 can be increased by providing a shielding wall made of a material such as ferrite that has good magnetic permeability but poor conductivity between these glue handles and the container m3a@101. However, in this case, there is also the problem that the structure of the reactor device 4.11 becomes complicated and the manufacturing thereof becomes troublesome.

An object of the present invention is to reduce the leakage magnetic flux that heats the container wall as described above, thereby making it possible to downsize a reactor device and facilitate manufacturing of the reactor device.

With the configuration described above, there is little leakage magnetic flux around the two coils, where the magnetomotive forces cancel each other out. Since the reactor operates based on the magnetic energy in the magnetic field generated by The reactor device can be made smaller and the reactor device can be manufactured more easily without reducing efficiency.

[Example] Figure 1 shows an air-core reactor 1 as a first example of the present invention.

It is a diagram. The difference between FIG. 1 and FIG. 7 is that an air-core coil 1 is connected in series with an air-core reactor 13 corresponding to the air-core reactor 2 in FIG.
In this case, the coils 14 and 15 connected in series are connected between the terminals U and V. Then, the coils 14 and 15 are spaced apart by C so that the magnetomotive forces Fil and Fl generated in each coil by one current I cancel each other out. That is, in this case.

Fll and Fll are equal in size and in opposite directions. Therefore, the temperature in the air core reactor 13 is F
The formation Φ due to lm and Fll exists only in the vicinity of the coils 14 and 15, and there is no leakage around the reactor 13. The late K.

When the reactor 13 is configured as shown in FIG.
11 is brought close to the reactor 13, the container wall will not be heated. Therefore, by bringing the container wall 3a closer to the reactor 13 and making the °C container 3 smaller, a reactor system consisting of the °C reactor 13 and the container 3 can be reduced. It would be great if the device 16 could be made smaller without reducing the power usage efficiency in the fj 116. In addition, in this case, the above-mentioned 9 air shielding 11k is placed in the container Jj! There is no need to provide it inside e3m.

In this case, the reactor 17 is composed of three sets of two coils 18 arranged apart from each other, and the reactor 17 is configured such that the magnetomotive force F generated by each of the two coils 18 forming the above-mentioned sets cancels each other out. They should be of equal size and oppositely oriented. In FIG. 2, since the reactor 17 is configured as described above and is located at 18°C, a first-class engineer flows through the reactor and no leakage magnetic flux is generated around the reactor, and the reactor 17 is located near each coil 18. ℃ reactor operation based on magnetic energy in a magnetic field. Therefore, if the accelerator 17 is adopted like this, the reactor storage container can be made small.

It is formed and machined to approximately the same size. Since the cored accelerator 19 is constructed as described above and has a temperature of 100° C., when the current I flows through the reactor 19, the reactor 19 becomes a bar whose magnetic pole strength is almost zero, consisting of the central legs 5a and 6a of the core and the gap 12a. It is equivalent to a magnet. Therefore, in the adle 19, there is one gap 12al12b.

Spaces 20a and 1 between L2C and 1 gaps 12a and 12b
Although there is magnetic flux due to the construction in the space 20b between the gaps 12a and 12G, almost no magnetic flux leaks around the reactor 19.

Therefore, by employing the reactor 19, it is possible to downsize the reactor device and facilitate manufacturing of the reactor device without causing a decrease in efficiency with respect to supplied power.
