Product Features

1Vacuum and Electromagnetic Oscillation Degassing Technology

The combined degassing technology of vacuum and electromagnetic oscillation can achieve a rapid and effective separation of dissolved gases in transformer oil under low vacuum conditions. It utilizes electromagnetic excitation and the vacuum volatilization of solutes to form a cyclic self-exciting loop of dissolved gases, all without any medium intervention. This method boasts high degassing efficiency, short processing time, and excellent repeatability, thereby preventing contamination of the transformer's insulating oil.

2Cold Trap Technology

In oil chromatography testing, the presence of oil and gas contamination of the chromatographic column's active substances can severely impact the column's separation efficiency and reduce its lifespan. Typically, adsorbents (such as activated carbon) are used to adsorb and filter out faulty gases, effectively reducing the contamination of the chromatographic column by oil and gas. However, the activation and regeneration properties of the adsorbents cannot meet the long-term stable operation requirements of online monitoring systems.

Cooling traps are designed to maintain transformer oil at certain low-temperature environments.C3The volatile organic components are effectively condensed, completely preventing oil and gas from contaminating the chromatography column, thus meeting the system's maintenance-free requirements.

3Composite Chromatographic Column

Replacing the dual-column setup with a composite single-column simplifies the system structure. Under certain temperature conditions, the composite chromatography column can effectively separate.H2、CO、CH4、C2H6、C2H4、C2H2The monitor is capable of detecting six types of fault gases, and under various isothermal conditions, the peak areas of each gas remain unchanged, which does not affect the peak detection conditions for system data processing. It is suitable for on-site installation in transformer oil chromatography online monitoring devices. The composite chromatography column boasts high column efficiency, excellent resistance to contamination, and a long service life.

4Gas Detector Technology

Integrating sensor technology, the sensitive components and control circuits are integrated onto a unique ceramic silicon chip. The corresponding design's fault gas detection chamber features a small dead volume, significantly enhancing the detection sensitivity.
