Product Introduction
JH3000 Series Online Monitoring System for Transformer Oil Chromatography (multi-component) consists of oil-gas separation module, component separation module, gas detection module, power module, communication module, etc., realizing gas collection, calculation, display and fault diagnosis functions in transformer oil. It can simultaneously monitor H2, CO, CH4, C2H2, C2H6, C2H4, CO2 gas content.
JH3000 Series Online Monitoring System for Transformer Oil Chromatography adopts chromatographic analysis principle and original vacuum degassing technology to detect seven full-component gases such as H2, CO, CO2, CH4, C2H4, C2H6, C2H2 and micro water in oil (O2 component detection can be customized according to user needs).
The system is suitable for detection of gas and micro water in oil-immersed high-voltage equipment such as power transformers, arc furnace transformers, reactors and transformers with voltage levels of 35kV and above. Through measurement and analysis of dissolved gases in insulating oil, it can timely discover and diagnose internal faults of transformers, keep track of equipment operation status at any time, make up for the long monitoring cycle of laboratory chromatographic analysis, and provide technical support for safe and economic operation of transformers and condition-based maintenance.
