1. loaded capacity-regulated switch;

  • Comprise moving contact, fixed contact and transition resistance;

    It is characterized in that;

    the high pressure winding middle part of transformer is provided with a transition tap, and said loaded capacity-regulated switch adopts six fixed contacts, four moving contacts and a transition resistance individual layer to arrange;

    It is terminal that said six fixed contact monolayer alignment are followed successively by winding head end, transition tap, neutral point and winding, and the winding end is split into three fixed contacts and connects and is equipotential;

    Said four moving contacts interlock;

    Wherein first moving contact is adjacent with second moving contact;

    The 3rd moving contact is adjacent with the 4th moving contact;

    Said transition resistance connect between first moving contact and the 3rd moving contact as auxiliary moving contact, and second moving contact is connected as the active contact through conductor with the 4th moving contact, assists moving contact and active contact when slipping away fixed contact, to form the double break mouth structure respectively.
