First, the working principle
The working principle of the 16000KVA oil-immersed transformer is the same as that of the 10000KVA oil-immersed transformer, which is based on the principle of electromagnetic induction. When the alternating current on the primary side passes through, it creates a changing magnetic field, which is transmitted through the core to the secondary side. On the secondary side, due to the change of the magnetic field, the induced electromotive force will be generated, so as to achieve the voltage change.
Second, structural characteristics
16000KVA oil-immersed transformer as a large transformer, its structural characteristics are as follows:
Iron core: The transformer is composed of silicon steel sheets with high permeability and has the characteristics of low hysteresis loss. The shape and structure of the core are optimized to reduce the reluctance and eddy current losses and improve the efficiency of the transformer.
Oil tank: The oil tank is the shell of the transformer, welded with high-quality steel plates, with good anti-corrosion performance and mechanical strength. The tank contains transformer oil for insulation and heat dissipation.
Winding: Winding is an important part of the transformer, using copper wire or aluminum wire wound. The primary side winding and secondary side winding of the transformer are connected to the power supply and the load respectively to realize the voltage change.
Heat sink: In order to reduce the temperature inside the transformer, the transformer uses a large heat sink to dissipate the heat by natural convection or forced ventilation. The structure of the heat sink has been optimized to improve the efficiency of heat dissipation.
Transformer oil: The transformer adopts special insulation oil, which has high electrical insulation strength and good stability. Transformer oil plays the role of insulation and heat dissipation in the transformer, and can effectively extend the service life of the transformer.
