Abstract

The invention provides an electronic-magnetic-stirring-based oil-gas separation device, which can be applied in the field of on-line monitoring of transformer oil. The oil-gas separation device comprises an oil-gas separation chamber connected with transformer body oil and a gas detection unit, and a piston device for vacuumizing the oil-gas separation chamber, wherein the oil-gas separation chamber is connected with the gas detection unit through a cold trap; and an electronic magnetic stirrer is arranged at the bottom of the oil-gas separation chamber. The electronic-magnetic-stirring-based oil-gas separation device integrates oil cycle sampling, electronic magnetic stirring degassing and the cold trap, radically avoids oil-gas pollution on a chromatographic detection unit, realizes a maintenance-free system, has the advantages of low cost, long service life, high stability and the like, and has an obvious effect higher than that of a traditional degassing mode.

Description

technical field [0001] The invention specifically relates to an oil-gas separation device used in a transformer oil on-line monitoring system. Background technique [0002] At present, transformer oil online monitoring has been widely used in the power industry. In this monitoring mode, the faulty gas dissolved in the transformer oil must first be effectively separated, and then the separated faulty gas is used as a sample gas for chromatographic analysis. Traditional degassing methods include: membrane equilibrium degassing, oscillation degassing, vacuum degassing and other methods. Membrane equilibrium degassing time is long and degassing efficiency is low; Oscillating degassing is incomplete degassing under certain constant temperature conditions, the time is short, the efficiency is low, the repeatability is poor, and it is easily affected by conditions such as temperature, pressure, and concentration; vacuum The degassing time is short and the efficiency is high, but ...
