To explain a conventional three-phase AC reactor with reference to FIG. 1, a W-phase coil 3 having lead terminals W and Z is placed on a base 1 via an insulating support 2, and a W-phase coil 3 having lead terminals W and Z is placed on the insulating support 2 again. A V-phase coil 5 and a U-phase coil 6 are stacked together via an intermediate support 4, an upper fixing bracket 7 is placed on top of the insulating support 2, and they are fixed together to the base 1 with a connecting rod 8. . The V-phase coil 5 has lead-out terminals V and Y, and the U-phase coil 6 has lead-out terminals U and X, respectively. As for the coils, the lower W-phase coil 3 and the upper U-phase coil 6 have the same winding direction, and the middle V-phase coil 5 has a magnetic flux linkage number, that is, an inductance of the coil, for each UVW phase due to the influence of the magnetic flux of each phase. In order to maximize the winding direction, the winding direction is opposite to that of the UW phases 3 and 6. When a three-phase current flows from the UVW terminal, the current flows in the V-phase coil 5 in the opposite direction. The magnitude of the magnetic flux of each phase is

ならない欠点があつた。 Figure 2a is a vector diagram representing the U-phase magnetic flux.
The vector sum of UVW is U′. When V is reversely wound, the vector sum of U-VW is U'',
U'' is larger than U and U'. Figure 2b is a vector diagram representing the V-phase magnetic flux, where the vector sum of UVW is V', and when V is reversely wound, the vector sum of U-VW is V ″ and V″ is greater than V and V′.Second
Figure c is a vector diagram showing the magnetic flux of the W phase, UVW
The vector sum of is W′, and the vector sum of U−VW is
W″, W″ is greater than W and W′. Therefore,
Winding the V phase in the opposite direction has the advantage of increasing inductance, but manufacturing only the V phase with the winding direction opposite to that of the UW phase requires complicated work.
Also, because of the lack of compatibility with the UW phase, there was a drawback that two types of coils had to be manufactured when preparing spare coils.
本発明の目的は、巻線作業の容易な交流リアク

An object of the present invention is to provide an AC reactor that is easy to wind.

In the reactor of the present invention, the coils are arranged in a single winding direction for three phases, and the input/output terminals of the V phase are opposite to the UV phase.
Each phase coil is tightened by a fixing metal fitting for each UVW phase, and the above purpose is achieved by stacking the UVW phases on a common base metal fitting and connecting and fixing the phases.
以下、本発明の実施例を第３図に示す交流リア

ル３，６と逆にして積み重ねている。 The base 1 is attached to one end of the lower fixture 7A via a bolt 11. Both ends of the W-phase coil 3 are fixed together by inserting interphase connecting bolts 8A between the lower fixing bracket 7A and the upper fixing bracket 7B via the insulating support 2, and tightening nuts 8B after installing them. . Fixing of the V-phase coil 50 and the U-phase coil 6 is also exactly the same as described above. U phase coil 6,V
The phase coil 50 and the W-phase coil are formed by winding conductors in the same direction. The V-phase coil 50 is replaced by the U-phase coil 6
and the W-phase coil 3, the input-side lead-out terminal Y and the output-side lead-out terminal V of the V-phase coil 50
However, the input-side lead-out terminals U, W and the output-side lead-out terminals X, Z of the other layer coils 6, 3 are arranged to be opposite to each other. That is, the arrangement of the V-phase coil 50 is reversed to that of the other-phase coils 3 and 6, and stacked one on top of the other.

る。 Therefore, the V-phase coil 50 is
Since a current flows in the opposite direction, the vector diagram of the magnetic flux generated at that time becomes a vector diagram similar to that shown in FIG. 2b. As a result, even if one of the phase coils, for example, the V-phase coil 50, is damaged and needs to be replaced, it is sufficient to always have one type of coil with conductors wound in the same direction. It is not confusing at times and can improve work efficiency during replacement. Furthermore, the present invention is economical because it requires at least one spare coil compared to the conventional coil shown in FIG. Furthermore, since each phase coil can be formed by winding the conductor in the same direction, the efficiency of the winding work can be improved.
