Abstract

The invention provides an amorphous dry type transformer. The amorphous dry type transformer comprises a high-voltage coil, a low-voltage coil and an amorphous alloy iron core; the amorphous alloy iron core is formed by amorphous strips in a winding manner; the amorphous strips are prepared by the following steps of providing pure Fe, FeSi alloy, pure B, pure Cu, pure Co and pure Gd raw materials;weighing the pure Fe, FeSi alloy, pure B, pure Cu, pure Co and pure Gd based on the molecular formula of Fe<(100-a-b-c-d-e)>SiBCu<c>Co<d>Gd<e>; performing cleaning and drying on the weighed pure Fe, FeSi alloy, pure B, pure Cu, pure Co and pure Gd raw materials to obtain materials to be used; putting the materials to be used into a crucible of a vacuum melting furnace; performing vacuum melting on the materials to be used to obtain a mother alloy; performing first heat treatment on the mother alloy; by taking the mother alloy after first heat treatment as the raw material, preparing theamorphous alloy strips by a single-roller quenching method; and performing second heat treatment on the amorphous alloy strips. The amorphous alloy disclosed in the invention is high in saturation magnetization strength, low in coercivity, high in resistance value, high in amorphous forming capability and excellent in comprehensive performance.

Description

technical field [0001] The invention relates to the field of amorphous alloys, in particular to an amorphous dry-type transformer. Background technique [0002] With the development of my country's national economy and modernization level, my country's urbanization rate is getting higher and higher. With the development of urbanization, the population is getting denser and the business is more and more developed. There are more and more places with higher requirements for fire prevention, such as large shopping malls, railway stations, hospitals, airports, subways, etc. The safety performance of the transformer puts forward higher requirements. Since oil-immersed transformers may cause explosion and fire hazards of transformer oil due to operational failure, they are not suitable for the above places. The dry-type transformer will not have similar dangers, and the insulating materials of the dry-type transformer are all flame-retardant materials, even if a fire occurs duri...
