A new type of non-casting dry-type transformer high and low voltage coil winding mold

Abstract

The invention belongs to the technical field of transformers and relates to a novel non-cast dry-type transformer high-low voltage coil winding die which at least comprises a high-voltage die end plate, a low-voltage die, a low-voltage die lantern ring, a winding die clamping sleeve, hexagon bolts, a high-voltage winding machine shaft, and a high-low voltage winding shaft transition shaft sleeve, wherein the high-voltage die end plate at least comprises a first high-voltage die end plate and a second high-voltage die end plate, and the winding direction of a coil changes according to different positions; the first high-voltage die end plate and the second high-voltage die end plate are respectively fixed at the quarter parts of the two ends of the low-voltage die through the hexagon bolts; the low-voltage die lantern ring is connected with the low-voltage die and the high-low voltage winding shaft transition shaft sleeve; the winding die clamping sleeve is fixed on the high-low voltage winding shaft transition shaft sleeve through the hexagon bolts, and the other end of the winding die clamping sleeve is connected with the high-voltage winding machine shaft. The invention provides the novel non-cast dry-type transformer high-low voltage coil winding die which has the advantages that the processing period is short, the product production period can not be influenced, and the product manufacturing cost is lowered due to shared use.

Description

technical field [0001] The invention belongs to the technical field of transformers, in particular to a novel non-casting dry-type transformer high and low voltage coil wrapping die. Background technique [0002] In the current general non-casting dry-type transformer high and low voltage coil winding process, the low voltage coil mold is removed after the low voltage coil is wound, and the low voltage coil is inserted into the low voltage coil with the same size as the low voltage coil mold but with a different height. Inner mould, plus high-pressure mold end plates at both ends. Such a method requires two sets of low-pressure inner film molds, and the cost of the coil is relatively high, and the processing cycle is long, which increases the manufacturing cost of the product. Moreover, the quality of the low-voltage coil will be affected during the process of breaking out of the low-voltage mold and loading into the high-pressure mold. Contents of the invention [0003]...
