Membrane device for monitoring separation of dissolved gases in transformer oil on line

Abstract

The invention discloses a membrane device for monitoring separation of dissolved gases in transformer oil on line. The membrane device mainly comprises a gas chamber front cover, a gas chamber rear cover, an oil chamber shell, a sleeve and a superfine pipe; the gas chamber rear cover is arranged on the oil chamber shell, the gas chamber front cover is fixed on the gas chamber rear cover, a gas chamber is formed in the gas chamber front cover, the top of the gas chamber front cover is provided with a gas inlet joint, the side wall of the gas chamber front cover is provided with a gas outlet joint, and the gas chamber is divided into an inner ring and an outer ring by the sleeve concentric with the gas chamber; the superfine pipe is arranged in the oil chamber shell in a 'U' shape, one end of the superfine pipe is in gas communication with the inner ring of the gas chamber, and the other end of the superfine pipe is in gas communication with the outer ring of the gas chamber; a gas circulating passage is formed among the gas inlet joint, the inner ring of the gas chamber, the interior of the superfine pipe, the outer ring of the gas chamber and the gas outlet joint; the side wall of the oil chamber shell is provided with an oil inlet and an oil outlet, and the oil chamber shell is sealed with the outside; and the gas chamber is air-tight with the outside, the inner ring and the outer ring of the gas chamber are in an isolation state, and the gas between inner ring and the outer ring is not communicated.

Description

technical field [0001] The invention relates to an online gas separation membrane device, in particular to an online separation membrane device for dissolved gas in shell-type transformer oil. Background technique [0002] The transformer oil online monitoring system belongs to the emerging technical field. The traditional fault diagnosis of transformer oil is to take the oil sample in the large oil-filled transformer body on site and bring it back to the laboratory for off-line chromatographic analysis, and monitor the operation status of the transformer by measuring the content of each component of dissolved gas in the insulating oil. The whole process Compared with online monitoring, the analysis cycle is time-consuming, the transportation distance is long, and the investment of manpower and material resources is large. With the development of science and technology, it is undoubtedly a time-saving and labor-saving method with a high degree of intelligence to monitor the...

Problems solved by technology

The more common method for these faulty gases is to use the off-line mechanical vibration method to remove the faulty gas and then use it for chromatographic analysis, which involves unfavorable factors such as whether the sealing of the degassing device is good, the error of the analysis result caused by the human operation link, etc.
