Dry Type Transformer

China Dry Phase Shift Rectifier Transformer

China dry phase shift rectifier transformer is a device that provides multiphase rectified power for medium and high voltage inverters. At present, the high-voltage frequency conversion regulation technology has developed rapidly, and the high-voltage-grade large-capacity frequency converter has been widely used, and the dry phase shifting transformer speed control is adopted, which can greatly reduce energy consumption and save production cost.
This series of products cooperates with the rectifying device in the high-voltage variable frequency speed control device to realize multiple rectification technology and effectively suppress the harmonic content. The high-voltage inverter adopting this series of products is a perfect non-harmonic inverter. And can improve the power factor, generally no need to be equipped with reactive power compensation and harmonic filtering device. The transformer uses NOMEX paper and is Class H insulated. The design of the transformer air duct is smooth, the whole structure process is good, the margin is large, and the overload capability is strong. According to the user’s structural requirements, the unique structure can be adopted, so that the inverter can occupy a smaller space. This product is especially suitable for use in environments with high fire protection requirements and high load fluctuations, such as offshore oil platforms, thermal power plants, water plants, metallurgical chemicals, mining and building materials and other special working environments.
Performance characteristics
1. The coil adopts mature design, technology and materials, which makes the product board small and strong against sudden short circuit;
2. The insulating material is made of Nobel’s NOMEX paper, the heat resistance grade is up to C grade, and the emergency load can be safely operated below 220 degrees, which reflects the super overload capacity;
3. Multi-phase with edge, multi-winding superimposed rectification, small feedback harmonics to the grid;
4. The magnetic density is controlled during product design, which makes the product over-excited;
5. Advanced simulation software combined with rich experience makes the product small and light, saving space and cost for customers;
6. DuPont’s NOMEX paper is safe, non-toxic, self-extinguishing and non-combustible, making the product safer and more reliable. read more

schneider dry type transformer manufacturer

schneider dry type transformer manufacturer

Schneider is a company, but also a standard, a high standard for the transformer industry.
But the Schneider standard is not a specific standard. Generally refers to the standard that Schneider needs to pass for certification. Most Schneider certifications use IEC or EN and DIN standards, and there are also a few corporate standards (group standards) that Schneider himself proposed. This standard is not only the detection of the final product, but also a test of the entire production process. Every detail in the production needs to meet the standard, which is why Schneider Electric Transformer has received everyone’s love.
  In 2012, ZTELEC Group successfully passed the audit of product quality and production process of France Schneider Electric, becoming its sole supplier in central China, and gradually becoming its most reliable supplier in the field of variable frequency special transformers.
We started producing dry-type transformers in 2008. Until now, we have not received customer complaints about quality. Schneider dry-type transformers are also our hot products.
