OPEN TYPE STEREOSCOPIC TRIANGLE AMORPHOUS ALLOY REEL IRON CORE

摘要

An open type stereoscopic triangle amorphous alloy reel iron core comprises an iron core body (1). The iron core body is a three-phase round core column combined by three identical closed iron core single frames (2), and the combined three-phase round core column is arranged in a shape of a stereoscopic equilateral triangle. Each iron core single frame comprises iron yokes (3) arranged on an upper end and a lower end of the iron core single frame, the iron yoke on one side of each iron core single frame is provided with an opening (4), and the iron core single frame can be assembled or disassembled at the opening. By providing the opening, which can be conveniently opened, on the iron yoke arranged on one side of each stereoscopic triangle amorphous alloy iron core single frame, coils can be independently wound in the production process of a transformer, and the finished coils are directly sleeved on the three core columns; therefore, the production efficiency is improved and the production cost is saved.
