DRIVING MECHANISM OF DISCONNECTOR FOR GAS DISTRIBUTING BOARD

摘要

PURPOSE: A driving mechanism of a disconnector for a gas distributing board is provided to prevent the unforeseen switching operation by generating an accurate and stationary displacement. CONSTITUTION: Driving motors are installed on upper and lower portions. A DS spindle shaft(15-22) is installed to a horizontal direction so as to be constant-rotated and reverse-rotated by the driving motor on the upper portion. An ES spindle shaft(15-23) is installed on the DS spindle shaft(15-22) to the horizontal direction and constant-rotated and reverse-rotated by the driving motor on the lower portion. A guide nut(15-25) is screw-coupled to the DS/ES spindle shaft(15-22,15-23) to move in right and left to the horizontal direction according to a constant/reverse rotation. A driving lath(15-26) is connected to upper and lower ends of the guide nut(15-25) to be moved right and left according to the right and left movement of the guide nut(15-25). A side end of a connect load(15-27) is connected to a central part of the driving lath(15-26) and the connect load(15-27) move simultaneously according to the right and left movement of the driving lath(15-26). A lower end of a triangular lever(15-28) is connected to an end of the connect load(15-27) and an upper end thereof is connected to an adjust link. An interlock instrument is coupled to the driving lath(15-26) to prevent an error operation.
