Embodiment 1
[0036] like figure 1 and figure 2 As shown, a multi-magnetic valve type single-phase controllable reactor has a four-column structure; it includes: an upper yoke 2, a lower yoke 4, two side yokes 3, and a pair of iron cores (X, Y) arranged between the upper and lower yokes. , the iron core (X, Y) is divided into five sections of discus 11, and the discus 11 of adjacent sections is isolated by magnetic valve 12 (four pieces); the discus is formed by laminating several silicon steel sheets;
[0037] The side yoke 3 is divided into four sections, and the adjacent sections are separated by air gaps 5 (three groups); the air gaps 5 are filled with epoxy resin, and the total thickness of the three groups of air gaps accounts for 5% of the height of the side yoke; It can prevent the nonlinearity of the reactor when the DC is no-load, so as to avoid the ferromagnetic resonance caused by the nonlinearity of the reactor.
[0038] like image 3 As shown, the magnetic valve 12 is comp...
Embodiment 2
[0051] like Figure 6 and Figure 7 As shown, a multi-magnetic valve type three-phase controllable reactor has a six-column structure; it includes: an upper yoke 2, a lower yoke 4, and three pairs of iron cores (X-X', Y- Y', Z-Z'), the iron core is divided into several sections of discus, and the adjacent sections of discus are separated by magnetic valves; the discus is made of several silicon steel sheets;
[0052] The magnetic valve is composed of a number of silicon steel sheets and a number of epoxy resin sheets alternately stacked in the horizontal direction; the magnetic valves on the iron core are divided into four categories: magnetic valve A, magnetic valve B, magnetic valve C and magnetic valve D; among them:
[0053] The total area ratio of the magnetically conductive sheet and the magnetically resistive sheet in the cross section of the magnetic valve A is 1:2, and the total thickness of this type of magnetic valve accounts for 28% of the total thickness of the m...
