Embodiment Construction
[0020] see figure 1 . The mounting plate 1 is horizontally and fixedly placed on the upper part of the inner cavity of the transformer, and its top surface is used to fix the operating parts, namely: the capacity adjustment operation mechanism 6, the first voltage adjustment operation mechanism 2 and the second voltage adjustment operation mechanism 3, these three The composition and structure of the mechanism are exactly the same, with a set of independent bistable permanent magnet assembly and its toggle lever 7 respectively. The coil in the bistable permanent magnet assembly is connected to the output end of the automatic controller on the transformer. The upper end of the toggle rod 7 is connected with the iron core of the coil, and is constrained by the iron core. The shaft extends downward through the mounting plate 1 . The bottom surface of the mounting plate 1 is used to fix the switch parts, namely: the first capacity regulating switch, the second capacity regulating...
