On the structure of European box-type substation
Today, let us popularize the knowledge of the equipment and equipment structure in the European box, so that we can choose better products.
What is the equipment in European box transformer?
The electrical equipment components in the European box transformer are selected with fixed products, and the technical performance of the components meet the corresponding standard requirements. In order to achieve the five protection requirements reliably, mechanical interlocking is used between the electrical components. The electrical components are installed on the structure with sufficient strength and stiffness to facilitate the connection of wires. The operation adopts electric mode, without additional power supply, it can be led out by TV. In addition, the European box transformer also has the function of electric energy detection, display, measurement, and can realize the corresponding protection function, but also has a special grounding guide, and has an obvious grounding mark. In addition to adapt to outdoor work environment, european-style box shell roof structure of interlayer, generally fitted with heat insulation material, at the bottom of the box body and each room has a cooling into the outlet, using natural air cooling and automatic control of a variety of forms such as forced air cooling, to ensure the normal heat dissipation of electrical equipment, has rainproof, dustproof, and measures to prevent small animals to enter, etc. The voltage level of domestic European type box transformer is 3 ~ 35kV on the high voltage side and 0.4 ~ 10kV on the low voltage side. The capacity of the transformer: when the rated voltage ratio is 35/10, 6, 0.4 kV can be from hundreds of kVA ~ tens of thousands of kVA, when the rated voltage ratio is 10, 6/0.4 kV can be from tens of kVA ~ thousands of kVA.
How is the equipment structure of European box transformer composed?
Low voltage room, transformer room, high voltage room is the type of layout, the European box change is the transformer and ordinary high voltage electrical equipment installed in the same metal shell box, box with ordinary high voltage load switches and fuses, low voltage switchgear, so the European box transformer volume is larger. European box transformer has been widely used in the urban power grid and industrial power grid below 22kV abroad, thus changing the installation of transformers on the pole and the cobweb wiring mode. It plays a good role in the safe and reliable operation of power network, reducing substation investment and speeding up the construction speed. It is one of the new development trends of substation equipment. In addition, the color of the box can also be designed to make it consistent with the use of the environment, which is conducive to beautify the environment. So it will be widely used in Chinese cities, rural areas, industrial and mining enterprises, public buildings.
There are many factors affecting the price of European box on the market. Typically, prices are influenced by raw materials, market conditions, research and development costs, and other factors. SHZPower is a high-tech enterprise with a long history, which is committed to the research, design and domestic and foreign trade of CNC dispensing machine, multi-color industrial printing press, electrical automation and low-voltage switchgear, box-type substation, distribution cabinet, multimedia box and other products.
