Since the early 1990s  for their Mat-glass products in China began to look for a way out, more than a dozen domestic power transformer manufacturers have launched the use of iron-based amorphous alloy material core frequency power transformers (hereinafter referred to as "non-transformer") to Replace the traditional silicon steel material core power transformer (hereinafter referred to as "silicon variable"). Happily, in recent years, China's own various types of amorphous magnetic materials development has also been rapid development. For example, the early start of the Shanghai Iron and Steel Research Institute, has formed the scale of the Iron and Steel Research Institute and other enterprises. 

The emergence of various types of amorphous soft magnetic foil materials, to solve the urgent need for product development of high-power switching conversion device. The operating frequency of such products is generally in the several Khz and even hundreds of Khz above, if the Po Mo alloy materials are expensive, a variety of large volume, high permeability ferrite materials sintering process difficulties ......, and iron-based amorphous alloys, FeNi-based amorphous alloys, iron-based amorphous nanocrystalline alloys, such as the launch of the material just to make up for this fault. 

Used in power transformers are iron-based amorphous alloys. Compared with high-quality silicon steel materials, its saturation magnetization density Bs is lower, the magnetostrictive effect caused by the noise is larger, the price is high, but its unit loss, permeability indicators are significantly better than high-quality silicon steel. 

I frankly admit that in this paper the author does not have the ability to iron-based amorphous alloy used in power transformers for the rights and wrongs of a comprehensive weighing, put forward concluding comments. But the author calls for, this issue involves a huge amount of investment funds flow of rationality, the government should lead the organization of authoritative institutions, authoritative people to carry out scientific evidence and put forward guiding opinions, including the following involved in no-load loss, load loss, "converted into monetary compensation", transformer, "assessment of the Price" and other issues to put forward suitable for our national conditions of the calculation method, assessment method.
