This product completely changes the rectangular planar structure of traditional amorphous alloy iron cores and creatively uses a three-dimensional coiled iron core structure. The iron core structure is not only more compact, but also uses fewer materials due to the reduction in volume, reducing the production cost of the iron core. Due to the approximately circular cross-section of the product, its coil winding can be made into a circular coil, which greatly improves the anti sudden short circuit ability of amorphous alloy transformers. The amorphous alloy three-dimensional coil iron core product has a unit no-load loss value of ≤ 0.2W/kg under testing conditions of 1.3T magnetic field density and 50Hz frequency; Unit excitation power value ≤ 0.6VA/kg. Compared with the traditional four frame five column amorphous alloy iron core, the production efficiency of this product is increased by about 20%. Due to the compact structure of the amorphous alloy three-dimensional coil iron core, the symmetrical coil structure reduces stray magnetic fields; At the same time, the space leakage is small, reducing electromagnetic radiation. Therefore, the amorphous alloy three-dimensional wound iron core transformer is much stronger in competition than traditional amorphous alloy transformers. The launch of this product will become a new highlight in the amorphous alloy transformer market. Compared with traditional silicon steel transformers, amorphous alloy three-dimensional coil transformers have significantly reduced no-load losses and no-load currents. At the same time, compared with conventional amorphous alloy transformers, they are more energy-efficient and have stronger resistance to sudden short circuits. Therefore, this product is truly an energy-saving and environmentally friendly product.
Suitable for use as a distribution transformer in power systems with an AC frequency of 50Hz and a rated working voltage of 10KV or below, as well as in enterprises such as petroleum, metallurgy, chemical, textile, light industry, and places with high dust.
