APPARATUS FOR DIAGNOSING STATE OF INSULATING OIL

PURPOSE: A device for diagnosing status of insulating oil is provided to check deterioration progression state of insulating oil inside a transformer and total amount of combustible gas which is dissolved in the insulating oil during deterioration by installing a pressure-resistant valve. CONSTITUTION: A device for diagnosing status of insulating oil(100) comprises an insulating oil measuring unit(110), a sensing unit(120), an induction pipe(130), a first connector(140), a second connector(150), and a circuit unit(160). The insulating oil measuring unit is connected to the end of the sensing part and is inserted into a transformer(300) and measures the status information of insulation oil(10) by contacting the insulating oil. One side of the sensing unit is connected to the insulating oil measuring unit and the other side is connected to the connector and transmits the status information of insulating oil measured from the insulating oil measuring unit as electric signals. The first and second connectors constitute a connection unit and remove a pressure-resistant valve(305) from a pressure-resistant valve connection part(310) and combine the connection unit with the pressure-resistant valve connection part. The circuit unit creates diagnosing information of the transformer based on the status information of the received insulating oil.
