Abstract

The invention relates to an automatic oil sampling device for oil and gas charging and an oil sampling method thereof. The device includes a tee-joint electrically operated valve. A first end port ofthe tee-joint electrically operated valve is in threaded connection with an oil sampling port, a second end port of the tee-joint electrically operated valve is communicated with an outlet end of an oil sample pipe, and a third end port of the tee-joint electrically operated valve is an oil discharging port. A piston extends into the inlet end of the oil sample pipe, and is connected to a motor through a screw so that the piston is driven to move along the length direction of the oil sample pipe. The inlet end and the outlet end of the oil sample pipe are provided with a travel switch respectively. The travel switches, the tee-joint electrically operated valve and the motor are electrically connected to a PLC controller. Beneficial effects of the device and the method are that an oil discharging path is controlled by the tee-joint electrically operated valve, the motor drives the screw to drive the piston to move in the oil sample pipe so as to extract an oil sample, automatic controlled oil sampling is achieved through control by the PLC controller, and the oil sampling efficiency is increased.

Description

technical field [0001] The invention relates to an oil-filled gas automatic oil extraction device and an oil extraction method thereof. Background technique [0002] At present, at least two people are required to take oil in the substation, and oil-taking syringes are required. The oil-taking syringes have a large contact area and need to be cleaned repeatedly. Impurities are easily mixed between the syringe and the piston. After cleaning, cover the syringe with a rubber cap and put it in the oil sample box for storage. There are two people in each oil extraction group, and it takes 15 to 20 minutes for each oil extraction group, which takes a long time. Contents of the invention [0003] The object of the present invention is to address the above deficiencies, to provide an oil-filled gas automatic oil extraction device and an oil extraction method thereof, so as to improve the oil extraction efficiency. [0004] The solution adopted by the present invention to solve t...
