The JH-02 Transformer Oil Chromatography Online Monitoring System can achieve automatic quantitative circulation cleaning, oil inlet, oil-gas separation, sample analysis, data processing, and real-time alarm; it can quickly monitor online the content and growth rate of dissolved fault gases in the oil of oil-immersed power high-voltage equipment such as transformers, and through the fault diagnosis expert system, it can early predict equipment fault hidden dangers, avoid equipment accidents, reduce major losses, and improve the reliability of equipment operation. As a new generation product in the field of online oil chromatography monitoring, this system will provide a stable and reliable solution for online remote DGA analysis of power transformers, and is a strong guarantee for the implementation of the condition-based maintenance system in the power system.
The JH-02 system is crafted by combining our company's nearly twenty years of successful experience in the operation of power chromatography automatic full degassing devices, and summarizing the advantages and disadvantages of online oil chromatography monitoring at home and abroad. This system maintains the advantages of stability, reliability, and accuracy that our company's products have always had:
