Why choose dry type transformers in the production process of European style box transformers
Firstly, there are certain requirements for selecting transformers for European style box transformers. As European style transformers are not only used as high-voltage to low-voltage transformation equipment, they are often also used for power boosting. Therefore, the overall performance and safety effect of transformers are of great concern. Dry type transformers are not as prone to fire as oil immersed transformers, as they contain insulating oil inside. They are composed of an iron core made of silicon steel sheets and coils cast with epoxy resin, which have relatively high safety performance.
Once again, the dry type transformer has a complete temperature detection, temperature control, and transformer protection system. The degree of device integration is relatively high, especially suitable for today's intelligent needs, and the device itself adopts an intelligent signal temperature control system and IMC wireless transmission protocol, which can automatically detect the temperature and load level of the device. Connected to the intelligent central control equipment of the box, there is a separate device alarm and early warning mechanism, with the function of timely tripping to ensure equipment safety.
Because the shell of the dry type transformer is filled and poured with epoxy resin and quartz sand, the overall equipment has the function of fire prevention and waterproofing, and can be suitable for places with high water molecule content in the air. It has good adaptability to other harsh environments, is pollution-free, and the equipment is relatively environmentally friendly. Adopting a multi-strand glass fiber impregnated epoxy resin winding structure, the overall loss is low, the energy-saving strength is high, and it is particularly suitable for use in most regions with very small limitations.
Because the dry type century old pressure vessel adopts relatively advanced processing technology and processes, with high mechanical strength, strong short-circuit resistance, and high overload capacity. It adopts natural air cooling and is also used in places with high intensity loads. The overall wiring method adopts a three-phase five wire connection, which greatly improves the equipment's lifespan and is basically maintenance-free
The reason why European style box transformers choose dry type box transformers is not only because of their rich characteristics, but also because their cost and price are relatively moderate and suitable for the development of European style box transformers.
