The iron core is made of amorphous alloy and in a three-frame and three-column structure. The winding comprises a high-voltage inner coil and a high-voltage outer coil which are distributed concentrically. The iron core positioning assembly comprises a groove-shaped lower clamping piece, a groove-shaped upper clamping piece and an iron core positioning support. The coil positioning assembly comprises a lower cushion block, an upper cushion block and a coil positioning support. The positioning base used for installation of the positioning assemblies comprises a lifting lug used for downwards lifting of a whole product. The transformer restrains iron core vibration from being directly transmitted to the coils, avoids production of additional noise, improves product performance, is obvious in effect and has good application prospects.

Background technology
Take non-crystaline amorphous metal as all kinds of transformers that magnetic conductive iron is made, because make use of the low advantage of non-crystaline amorphous metal loss, there is obvious energy-saving effect, but non-crystaline amorphous metal is to mechano-sensitive, in structural design, for avoiding amorphous alloy core stressed as far as possible, not with iron core for main load-bearing structural member.
Traditional dry-type earth transformer, be magnetic conductive iron with silicon steel sheet, no-load loss is high.Iron core is suspended on coil and avoids with iron core for main load-bearing structural member by amorphous alloy iron core dry type transformer, but the structure that this coil is stressed, during operation, iron coring vibration is directly delivered to coil, produces additional noise.
Summary of the invention
The technical problem to be solved in the present invention is: for solving the problem, and provides a kind of three-phase amorphous alloy dry-type earth transformer reducing no-load loss, effectively restrain additional noise.
A kind of three-phase amorphous alloy dry-type earth transformer of the present invention, comprises iron core, winding, positioning component unshakable in one's determination, coil location assembly, positioning base, and described iron core adopts non-crystaline amorphous metal, is three frame three rod structures; Described winding comprises high pressure interior loop and each one of the high pressure exterior loop of arranged concentric, and winding connection way is ZN; Described positioning component unshakable in one's determination comprises flute profile lower clamping piece, flute profile upper clamping piece, locating support unshakable in one's determination; Described coil location assembly comprises lower cushion block, upper cushion block, coil location support, described positioning base for installing positioning component, the hanger lifted by crane under comprising whole product.
The beneficial effect that the present invention adopts above-mentioned technical solution to reach is: above-mentioned measure can overcome the deficiency of coil force structure, by coil and structure of locating respectively unshakable in one's determination, restriction iron coring vibration is directly to coil transmission, avoid producing additional noise, enhance product performance, have a good application prospect.
