The invention discloses a quantitative liquid taking device for an oil-gas separation device. The quantitative liquid taking device comprises an oil inlet stop valve, an oil inlet pipeline, an oil taking part, a quantitative tank, an oil taking stop valve, an oil return stop valve, an oil return stop valve and a main loop stop valve. The oil inlet stop valve and the main loop stop valve are connected with oil charging equipment; an oil inlet of the oil taking part is connected with the oil inlet stop valve through an oil inlet pipeline, and an oil outlet of the oil taking part is connected with an oil inlet of the quantitative tank; the main loop stop valve is connected with the oil return stop valve and the oil return stop valve through a tee joint; the oil return stop valve is connectedwith an oil return port of the oil-gas separation device; an oil outlet of the quantitative tank is connected with the oil taking stop valve and the oil return stop valve through a tee joint; and theoil taking stop valve is connected with an oil taking port of the oil-gas separation device. According to the quantitative liquid taking device, the oil taking part and the quantitative tank are additionally arranged in the pipeline, an overflow structure is adopted in the oil taking part, the oil taking part is automatically disconnected from a front-section oil product during oil taking, and theaccuracy of the oil taking amount is guaranteed.
Description
technical field [0001] The invention relates to the field of electric equipment fault detection, in particular to a quantitative liquid extractor used for an oil-gas separation device. Background technique [0002] Oil-filled equipment is widely used in power systems and is an indispensable part of the safe and stable operation of the power grid. When a fault occurs inside these devices, related gases will be generated, and the gas will be continuously dissolved in the insulating oil through convection and diffusion. Their composition and content are closely related to the type and severity of the fault. Therefore, analyzing the gas dissolved in the oil can detect latent faults in the equipment as early as possible, and monitor the development of faults at any time. [0003] At present, the conventional practice is to go to the site to collect oil samples and bring them back to the laboratory, while the process of degassing / returning oil and chromatographic analysis is comp...
