S11 250kva 10kv 3 Phase Oil-Immersed Electrical Power Distribution Transformer
Structural features:
A. The coil adopts a low axial short-circuit force structure, which can greatly reduce the axial short-circuit force of the transformer and greatly improve the ability of the transformer to withstand short circuit when the transformer has a short circuit.
B. The transformer body adopts a high reliability support structure to ensure that the upper and lower parts of the coil are reliably pressed. The whole body structure makes the transformer have strong ability to withstand short circuit.
C. The low magnetic flux density is selected in the design, which not only reduces the no-load loss of the transformer, but also ensures that the core magnetic flux is not saturated when the transformer operates under voltage, making the third harmonic of the transformer movement very small.
D. All bolts and nuts on the tank cover are made of 304 stainless steel, which enhances the antirust ability of the transformer surface.
E. Each sealing rubber ring adopts the best rubber ring in China, which greatly extends the service life of the sealing rubber ring.
Features:
1. Long service life. Usually, they can be used for 5-10 years or even longer. 2. Easy to install and maintain. Most oil-immersed transformers have enclosure protection devices, so you do not need special equipment to repair its sealing components or replace it. 3. It can be used for different types of power supply. For example, for hospital operating room lighting system, this type of transformer is suitable for standard DC power supply; For household appliance switches, it is suitable for AC power supply. 4. Easy to generate noise. This is because they are usually embedded design and equipped with metal base, which makes them more robust. These advantages make them have a good reputation among users, but their disadvantages are also obvious, that is, the running noise is large.
Characteristics of the site
With the increasing demand for industrial and civil electricity, oil-immersed transformers are also developing rapidly. At present, there are many different types of products with superior performance on the market, which meet the needs of various users. In China, oil-immersed transformers are mainly used in power plants, petrochemical enterprises and large enterprises. These industries have high requirements for power quality, and oil-immersed transformers have good insulation performance and high temperature resistance characteristics, so they are widely used in various applications. In addition, oil-immersed transformers are widely used in power systems because they can realize ultra-high voltage and withstand a certain degree of current impact. In view of the advantages and broad prospects of oil-immersed transformers, many power companies hope to have their own special equipment. For those units that need high-voltage test or maintenance, the use of oil-immersed transformer is a very useful choice.
