Press-fitting inner supporting device for amorphous alloy oil-immersed transformer coil

Abstract

The invention discloses a press-fitting inner supporting device for an amorphous alloy oil-immersed transformer coil. The inner supporting device comprises an upper end plate and a lower end plate which are arranged in parallel; a lower external thread column is welded to the lower surface of the upper end plate; an upper external thread column is welded to the upper surface of the lower end plate; the lower external thread column and the upper external column are connected through an internal thread pipe; a positioning part for alignment is arranged between the upper end plate and the lower end plate and comprises an upper positioning column welded to the lower surface of the upper end plate and a lower positioning column welded to the lower surface of the lower end plate; the lower positioning column is a hollow pipe; the lower end of the upper positioning column is inserted in the hollow pipe and is closely combined with the inner wall of the hollow pipe. According to the press-fitting inner supporting device, the distance between the upper end plate and the lower end plate is adjusted through threaded transmission of the internal thread pipe and the external thread column, and alignment of the upper end plate and the lower end plate is achieved through the guiding function of the positioning part. The inner supporting device has the advantages of being simple in structure, convenient to operate, small in specification number and high in universality.

Description

technical field [0001] The invention relates to the technical field of amorphous alloy oil-immersed transformers, in particular to a press-fit inner supporter for amorphous alloy oil-immersed transformer coils. Background technique [0002] Amorphous alloy transformer is a new type of high-efficiency energy-saving transformer that uses a new type of magnetically conductive material-amorphous alloy strip to make a core. The most prominent feature of the amorphous alloy transformer is that the no-load loss and no-load current are very small, and it is a distribution transformer with a very good energy-saving effect at present. For more than 20 years, amorphous alloy transformers have been widely used in domestic and foreign power grids. [0003] At present, due to the compact structure of the amorphous alloy oil-immersed transformer, after the coil is wound, it needs to be shaped, pressed, solidified and shaped, and the whole process needs to be carried out with an internal m...
