Abstract
The invention discloses a miniaturized selection switch assembly used for an on-load tap changer. The selection switch assembly comprises a grooved pulley mechanism assembly, an insulation installation mainboard, a bearing, moving contacts and a static contact group. According to the invention, two dials in the grooved pulley mechanism assembly sleeve a transmission square shaft of the on-load tap changer through different angles to drive two corresponding grooved pulleys to rotate according to different time sequences, the two grooved pulleys respectively drive the moving contacts to rotate according to different time sequences so as to complete connection conversion between two adjacent static contacts, and thus voltage-adjusting gear selection of the on-load tap changer without power failure is completed. According to the invention, the mechanical structure of the selection switch assembly of the on-load tap changer is simplified, the reliability of the on-load tap change is improved, at the same time, the volume of the selection switch assembly is greatly reduced, and the cost is decreased.
