PURPOSE: A pre-treating apparatus of a vial for the gas analysis of insulating oil is provided to pre-treat multiple vials by simultaneously injecting argon gas to the vials. CONSTITUTION: A pre-treating apparatus of a vial for the gas analysis of insulating oil comprises an argon gas supply unit(100), a multi-channel pressure regulator(200), a timer valve(400), a gas flowmeter(500), and a controller(300). The argon gas supply unit supplies argon gas for purging vials(700) to the vials. The multi-channel pressure regulator supplies the argon gas to the vials through multiple transfer lines with uniform pressure. The timer valve allows the argon gas to be transferred through the transfer lines during a pre-determined time. The gas flowmeter is connected to the vials and regulates the flow rate of the argon gas. The controller controls the multi-channel pressure regulator to uniformly maintain the pressure of the argon gas.
