Abstract

The invention provides a vacuum oil-gas separator used for transformer on-line monitoring. The separator comprises: an oil-gas separation chamber connected with transformer body oil and a gas detection unit, a vacuum-pumping device used for vacuum-pumping of the separation chamber, an ultrasonic generator installed in the oil-gas separation chamber and a cold trap connecting the oil-gas separation chamber and the gas detection unit. The vacuum oil-gas separator of the invention integrates circulating sampling, vacuum ultrasonic degassing and cold trapping, thus thoroughly avoiding oil gas pollution on a chromatographic column and realizing a maintenance-free system really. With the advantages of low cost, long service life and good stability, etc., the vacuum oil-gas separator provided in the invention has obviously higher effect than traditional degassing modes.

Description

technical field [0001] The invention relates to transformer on-line monitoring technology, in particular to a vacuum oil-gas separation device used in a transformer oil chromatography on-line monitoring system. Background technique [0002] At present, online monitoring of transformer oil chromatography 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, a...
