Technical Features
Heat Transfer Method
The system employs a heat-exchange model, wherein the heating medium is preheated before facilitating heat exchange with the transformer oil via a plate heat exchanger. This technology effectively prevents oil cracking caused by thermal stress accumulation during sudden power outages, while simultaneously enhancing both temperature uniformity and energy efficiency. The method is characterized by its safety, efficiency, and energy-saving performance (reducing electricity consumption by 30%).
Degassing Method
An optimized single degassing tank is utilized to thoroughly remove gases and moisture from the transformer oil. The system is equipped with vacuum pipes featuring high-performance condensers and oil-gas separators to maintain operational stability and performance.
Filtration
Newly designed, precision-customized filter cartridges with high dirt-holding capacity are employed to comprehensively remove solid particles from the oil, meeting the stringent requirements of ±1,100 kV direct current transformers.
Control
Siemens PLC (Programmable Logic Controller) is employed for precise, automated, and reliable control of the entire system.
Additional Features
Precision-machined components and the use of internationally renowned brands ensure high mechanical and electrical reliability, minimizing maintenance costs and guaranteeing consistent operational efficiency.
