PURPOSE: A driving unit of a gas insulated switchgear and a long distance isolation operation structure of an auxiliary contact are provided to reduce the size of the instrument by independently unitizing the driving unit and the auxiliary contact. CONSTITUTION: A gas insulated switchgear(300) comprises a machine unit(310), a driving unit(320), and an auxiliary contact(330). The driving unit operates the machine unit through a flexible shaft(340). The auxiliary contact senses the rotation angular displacement of a driven shaft(240), and sends the on/off status of the machine unit to a display panel as an electric signal. The auxiliary contact and the driving unit are independently unitized, able to be separated. The driving unit is installed separately from the machine unit, and the auxiliary contact is attached to one side of the outside of the machine unit of the gas insulated switchgear. |
