APPARATUS FOR MONITORING DISSOLVED GAS IN OIL

摘要

PURPOSE:To prevent the dissolved gas in insulating oil bubbled in a gas extraction chamer from peneratrating into an oil immersed electric machinery tank, by bringing a gas detection chamber into commucation with the gas extraction chamber and sending the dissolved gas in the oil bubbled in a space into the gas detection chamber. CONSTITUTION:To a gas extraction chamber 3 in which insulating oil is stayed, an insulating oil recirculation passage 6 for recirculating oil between the gas extraction chamber 3 and an oil immersed electric machinery tank 1 and a space generation means 13 for generating a space in the gas extraction chamber 3 are provided. The base and part of oil jet piping 8 is connected to the insulating oil recirculation passage 6 and the leading end part of said piping 8 to the interior of the gas extraction chamber 3 and a gas detection chamber 4 is brought into communication with the gas extraction chamber 3 to send the dissolved gas in the oil bubbled in the space into the gas detection chamber 4.
