Wire-shell integrated water-cooling pouring type transformer and manufacturing method thereof

Abstract

The invention discloses a wire-shell integrated water-cooling pouring type transformer and a manufacturing method thereof, and belongs to the field of power electronics. The wire-shell integrated water-cooling pouring type transformer comprises an iron core, a primary winding, two secondary windings and four water connectors. Bolts and clamping pieces clamp and fix the first secondary winding and the second secondary winding to an insulating base plate, a baffle is additionally arranged on a butting face between the first secondary winding and the second secondary winding, and therefore enough insulating space is kept. The first secondary winding, the second secondary winding and the base plate form a pouring shell. The primary winding is placed into the pouring shell, epoxy glue is poured in the shell, and therefore the primary winding is fixed into the shell to be a whole. The water connectors are installed after solidification. According to a product schematic diagram and an assembling diagram, 5' is connected with 5', and two whole turns of the secondary windings are achieved. According to the wire-shell integrated water-cooling pouring type transformer and the manufacturing method thereof, the secondary windings, a water-cooling system and the shell are integrated, the problems that a traditional single-phase high-frequency water-cooling pouring transformer is large in size, large in occupied space and high in cost are overcome, and the problem that a single-phase high-frequency water-cooling pouring transformer in the field of power electronics is complex in structure is solved.

Description

technical field [0001] The invention belongs to the field of power electronics, in particular to a manufacturing method of a new single-phase high-frequency water-cooled casting transformer. Background technique [0002] Traditional single-phase high-frequency water-cooled casting transformers are composed of transformer primary windings, secondary windings, water cooling systems, and casting shells. The water-cooling system is to install a water-cooling plate between the windings, and make a casting shell separately. Although the single-phase high-frequency water-cooled casting transformer manufactured in this way can meet the performance and use requirements of water-cooling and casting transformers, it has the disadvantages of adding water-cooled plates and casting shells to occupy a large space, high cost, and cumbersome manufacturing procedures. [0003] With the development of power electronics technology, it is necessary to solve the problems of heavy weight and larg...
