The beneficial effect of the utility model:
1, the utility model core loss descends more than 70%, and present iron loss has only and can be 1/5 ~ 1/10. original every year more than country's economize on electricity at least 20 hundred million degree, reduces the loss more than 1,200,000,000 yuan.
2, the three phase mains transformer area of the utility model descends more than 30%, has improved the plane and the utilization of space of ammeter, helps product miniaturization and heat radiation, has improved security of products and reliability.
3, the iron core weight of the utility model three-phase transformer and volume reduce nearly 1/3.Effects of energy conservation and environmental protection is obvious, benefits the nation and the people.
4, the utility model has been filled up the blank of China (9-20) VA amorphous three-phase electronics transformer reactance device, for the development of China's small-power amorphous three-phase electronic transformer provides solid foundation.
5, the utility model can be widely used in fields such as military project communication, space flight and aviation, instrument and meter, medicine equipment, automation control and can have a tremendous social and economic benefits.
