JHZX-GP20 type, transformer oil spectrum online monitoring device
Using TDLAS detection principle combined with negative pressure-constant temperature-dynamic headspace degassing technology, the minimum detection value of C2H2 is less than or equal to 0.2 μL/L, which meets the national grid enterprise standard Q/GDW10563-2021 750kV and above voltage class A standard
It can realize automatic quantitative cycle cleaning, oil intake, oil and gas separation, sample analysis, data processing, and real-time alarm
Rapid on-line monitoring of dissolved fault gas content and growth rate in oil of oil-immersed power high voltage equipment such as transformers
Early prediction of equipment failure hazard information through fault diagnosis expert system to avoid equipment accidents, reduce major losses, and improve the reliability of equipment operation
