Abstract
The invention relates to a large-capacity single-body phase-angle regulator. The phase-angle regulator adopts a single-body structure; the arrangement sequences of the loops of each phase from a core limb to the outside are as follows in sequence: a first pressure regulating loop, a basic loop and a second pressure regulating loop; the first pressure regulating loops and the second pressure regulating loops of each phase are respectively connected to the corresponding vacuum loaded pressure regulating tapping switches of each own; the same name terminals of the first pressure regulating loops and the second pressure regulating loops of each phase are respectively connected with the positive switching positions and the negative switching positions of the corresponding vacuum loaded pressure regulating tapping switches of each own. The large-capacity single-body phase-angle regulator has the beneficial effects that the capacity of the phase-angle regulator is large and below 600MVA; the manufacture cost is low; the occupied area for mounting is small, the manufacture is convenient and the manufacture cost of the phase-angle regulator with the same capacity specification is only 70 percent of that of a double-body structure.
