Self-protection three-column amorphous alloy transformer

Abstract

The invention discloses a self-protection three-column amorphous alloy transformer which comprises an amorphous alloy iron core, integrated winding coils, an upper clamp and a lower clamp, wherein the integrated winding coils comprise high-voltage coils and low-voltage coils. The amorphous alloy iron core comprises two square iron core frames, the integrated winding coils are respectively sleeved on three core columns formed by the two iron core frames, the high-voltage coils and the low-voltage coils in the integrated winding coils are square aluminum foil coils made of epoxy resin by casting, the high-voltage coils are sequentially serially connected with overload protection devices through lead terminals, so that the transformer has voltage conversion and power transfer functions, further has breaking current and lightning, short circuit and overload protection functions and is effectively protected, the amorphous alloy iron core and the integrated winding coils sleeved on the amorphous alloy iron core are connected between the upper clamp and the lower clamp in a locked manner, and one buffer is arranged between one axial end of the amorphous alloy iron core and the upper clamp, and one buffer is arranged between the other axial end of the amorphous alloy iron core and the lower clamp.

Description

technical field [0001] The invention relates to the technical field of amorphous alloy transformers, in particular to a self-protecting three-column amorphous alloy transformer. Background technique [0002] The existing research on amorphous alloy transformers mainly focuses on the development and improvement of its voltage conversion and power transmission functions. The overload protection of amorphous alloy transformers mainly depends on external overcurrent relays. These external protection The device is not only inconvenient to install, but also occupies a large area, and its reliability is poor. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a self-protecting three-column amorphous alloy transformer, which has good lightning, short-circuit and overload self-protection functions. [0004] The technical scheme adopted by the present invention to solve the technical problem is: a self-protecting thre...
