Three-phase three-pole amorphous iron-core with support and hoisting structure as well as manufacturing method thereof

Abstract

The invention relates to the technical field of transformer manufacture, in particular to a three-phase three-column non-crystalline iron core with a support and a lifting structure, and a method for manufacturing the same. The three-phase three-column non-crystalline iron core comprises a non-crystalline iron core, a non-crystalline thin strip cut joint opening, a resin rubber coating, an insulating material, a supporting iron plate, an upper clamp and a lower clamp, a lifting lug, a pedestal and the like, wherein the non-crystalline iron core consists of an outer iron core and two inner iron cores; the end face and the inner layer of the iron core are agglutinated with the orographic supporting iron plate through a resin adhesive; the outside of the iron core agglutinated with the supporting iron plate is tightened by the upper clamp and the lower clamp; and the upper clamp is provided with the lifting lug, while the lower clamp is arranged with the pedestal. With the supporting iron plate, the non-crystalline iron core can be supported without depending on coils, and with the clamps, the iron core is fastened into a whole. The non-crystalline iron core is convenient to erect and lift, improves the assemblies of the iron core and the coils, reduces applied stress, improves the loss and the noise of the iron core, and upgrades the quality of a non-crystalline transformer, thus the manufacture of a large-capacity non-crystalline iron core transformer is practicable.

Description

【Technical field】 [0001] The invention relates to the technical field of manufacturing amorphous iron cores in the field of power transformers, in particular to a three-phase three-column amorphous iron core with a supporting and hoisting structure and a manufacturing method thereof. 【Background technique】 [0002] At present, three-phase five-column and three-phase three-column amorphous cores are usually used in the manufacture of power transformers. Since the amorphous core of a three-phase transformer cannot support its own weight due to its insufficient strength, the general transformer The core structure is to hang the iron core on the coil. However, as the capacity of the transformer increases, the weight of the iron core becomes heavier, resulting in an increase in the burden on the coil and difficulties in assembly, thus limiting the capacity of the amorphous core transformer. 【Content of invention】 [0003] The purpose of the present invention is to overcome the...
