SF6 SF SF6 GAS COMPONENT ANALYSIS AUXILIARY DEVICE FOR GAS INSULATED SWITCHGEAR AND SF6 GAS COMPONENT ANALYSIS METHOD USING THIS SAME

摘要

Disclosed are an SF6 gas composition analysis auxiliary device for a gas insulated switchgear and an SF gas composition analysis method using the same. The disclosed SF6 gas component analysis auxiliary device, which connects a plurality of gas valves for discharging SF gas in each section of a gas insulated switch gear to a gas analysis device, and supplies the SF gas from the gas valves to the gas analysis device, comprises: a connection pipe unit including a plurality of first connection pipes respectively connected to a plurality of gas valves, a second connection pipe for connecting ends of the first connection pipes to each other, and a third connection pipe formed at a side end of the second connection pipe and having a gas analysis device connected thereto; a connection pipe module including a valve unit including a plurality of first manual opening/closing valves respectively installed on the first connection pipes, a second manual opening/closing valve installed on the third connection pipe, and a third manual opening/closing valve installed on the second connection pipe; and a vacuum pump installed at an end of the second connection pipe to allow the inside of the connection pipe unit to be a vacuum state.
