New amorphous materials successfully used in dry-type transformers

Recently, China has developed a new type of high saturation magnetic induction Fe82.5Si6B6P5C0.5 amorphous material, and built a pilot production line with an annual capacity of 300 tons. This will have a huge impact on China's international competitiveness. High saturation magnetic flux density amorphous materials with higher work flux, can improve the power density of amorphous products (transformers, motors, etc.), reducing the amount of iron core, copper wire, chassis and other materials. High saturation magnetic induction Amorphous materials with higher work flux density, can improve the power density of amorphous products (transformers, motors, etc.), reduce the amount of iron core, copper wire, chassis and other materials, reduce production costs and expand the application Therefore, it is widely valued. Recently, with the support of Beijing Municipal Science and Technology Commission, a new high-saturation magnetic induction Fe82.5Si6B6P5C0.5 amorphous material was jointly developed by Aetna Technology Co., Ltd., Beijing Career Power Distribution Corporation and North China Electric Power University, and an annual output of 300 Tons of pilot line. The material has a saturation magnetic induction of 1.71T and a coercive force of 2.3A / m, which has the advantages of low loss and high permeability. The material has been successfully applied to SCBH15-630 / 10 dry-type transformers, to meet the national standards under the premise of reducing the amount of 8.4% iron core material, 5.1% copper. This achievement has broken through the composition and structural design technology of the existing amorphous material system, promoted the application of high saturation magnetic flux density amorphous materials in the distribution transformer and high-speed spindle motor industry, promoted the new type of high saturation magnetic induction amorphous material, International competitiveness of high power density amorphous transformers and amorphous motors.
