Main Application

• Evacuation of electrical equipment such as power transformer and electric reactor.
• Filling of the vacuum equipment with oil.
• Generating of hot oil circulation in these machines. 

Technical Parameters

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.
