[0002] The special dyeing chromatographic column for transformer oil is a tool for transformer oil analysis. It mainly works based on chromatographic principle. Chromatography is a technique for separating and analyzing mixtures. In transformer oil analysis, the dyeing chromatographic column can help separate various components in transformer oil, such as different hydrocarbon substances, additives, and possible impurities.

[0003] However, the existing special dyeing chromatographic column for transformer oil needs to be manually installed on the upper end of the chromatograph by the staff during use. During installation and use, the surrounding environment needs to be kept clean to prevent dust, oil stains, and other contaminants from entering the column. Since the hands of the staff and the surrounding environment are not always clean, the staff's hands are prone to leaving stains on the upper end of the special dyeing chromatographic column for transformer oil during installation, which causes the external contamination of the special dyeing chromatographic column for transformer oil. When the special dyeing chromatographic column for transformer oil is stored, the external contaminants of the special dyeing chromatographic column for transformer oil enter the internal part of the special dyeing chromatographic column for transformer oil during storage. Therefore, it does not meet the current needs, and thus we propose a special oil-resistant and anti-pollution chromatographic column for transformer oil. UTILITY MODEL CONTENT
