PURPOSE: A 3-way switching device of a gas insulated switchboard is provided to simplify a connection structure for transmitting rotation force to insulated spindles by simultaneously rotating a plurality of insulated spindles through one chain. CONSTITUTION: A service contact(20), a disconnecting contact(30), and a ground contact(10) are successively mounted in an insulator mold(40). An insulated spindle(70) is driven by a motor(60). A first sprocket wheel(62) is connected to a second sprocket(71) with one chain(80). The second sprocket wheel is rotated with the first sprocket wheel. An operating terminal(50) is screwed with the insulated spindle. |
