In terms of structure, the transformer adopts a fully sealed structure, which can effectively prevent the interference and intrusion of the external environment and ensure the normal operation and service life of the transformer. At the same time, the transformer also adopts advanced coil design and core material, which makes it have higher conversion efficiency and lower losses.
Second, performance. The main performance indicators of this isolation transformer are as follows:
1.Input voltage: 690V
2.Output voltage: 400V
3.Rated capacity: 2500kva
4.Conversion efficiency: 98%.
5.Insulation class: Class H.
6.Cooling method: oil-immersed self-cooling.
7.Working environment: -20 +40
The isolation transformer has high conversion efficiency and low loss, which can effectively improve the energy storage efficiency and operation stability of centralized energy storage power station. At the same time, it has a high input and output voltage range, which can meet the needs of different occasions and applications. In addition, it also has good heat dissipation performance and insulation performance, which can ensure the normal operation and service life of the transformer.
3. Advantages. This isolation transformer has the following advantages:
