Filtering layer of online transformer oil chromatography monitoring system

Abstract

The invention discloses a filtering layer of an online transformer oil chromatography monitoring system. The filtering layer is characterized by comprising a substrate (1); a plurality of sieve pores (2) are uniformly distributed in the substrate (1); the fracture surfaces of the sieve pores (2) are of trumpet shapes with the consistent direction, and are all provided with large pores (3) and small pores (4), the value range of the large pores (3) is 0.8-1.2 microns, and the value range of the small pores (4) is 0.1-0.2 micron; meanwhile, the lateral sides (5) of the trumpet-shaped sieve pores (2) are respectively in a step shape, and consist of at least three equal steps (6). The filtering layer of the online transformer oil chromatography monitoring system can be convenient for back-flushing treatment.

Description

technical field [0001] The invention relates to a filter layer structure, in particular to a filter layer used in a transformer oil chromatography on-line monitoring system. Background technique [0002] In the process of using the transformer oil chromatographic on-line monitoring system, the carrier gas comes from air: the carrier gas pump compresses the air and sends it to the carrier gas bottle for storage. The generating device needs to use a filter layer to filter the air to prevent impurities in the air from entering the carrier gas, but the traditional filter layer has the disadvantage that the filter layer has a large mesh diameter and can only trap larger particles in the air Or impurities, for smaller impurities can not be filtered; especially when the filter layer is working for a long time in a humid and dusty environment, the sieve holes are very easy to block, once the blockage occurs, the filter layer can only be removed Dismantling and cleaning thoroughly, ...
