REMOTE OPERATING STRUCTURE OF DRIVING UNIT IN GAS INSULATED SWITCHGEAR

摘要

PURPOSE: A long distance operating structure of a driving unit of the gas insulated switchgear is provided to operate a machine unit of the gas insulated switchgear from the driving unit which is in the long distance, by using a flexible shaft. CONSTITUTION: A machine unit(110) comprises a driven shaft(120) which straightly reciprocates a movable element. A driving unit(140) comprises a driving shaft(130) which is able to be moved passively. A flexible shaft(310) is connected to the driven shaft which is protruded from one side of an external container(112) of the machine unit. The flexible shaft delivers the rotational movement power of a driving shaft to the driven shaft in a straight line or bent status. The driving unit comprises an auxiliary contact(320) which is able to show the opened or closed circuit status of the machine unit with an electric signal.
