Triangular iron core reactor

Abstract

The invention discloses a triangular iron core reactor, which comprises three columnar iron cores, coils, an upper yoke iron and a lower yoke iron, wherein the three columnar iron cores are symmetrically arranged in 120 degrees; the coils are wound on the three columnar iron cores respectively; and the upper yoke iron and the lower yoke iron are connected with the three columnar iron cores respectively to form a whole. The three columnar iron cores have a triangular symmetric structure in 120 degrees relative to the centers of the upper yoke iron and the lower yoke iron. Because the triangular iron core reactor consists of the upper yoke iron and the lower yoke iron, the three columnar iron cores distributed in 120 degrees and the columnar iron coils which are connected to form a whole, the three-phase magnetic circuits of the reactor are balanced and symmetric, and the reactor self does not initiate harmonic wave.

Description

technical field [0001] The invention relates to a reactor in a power system, in particular to a square-shaped reactor applied to a power system. technical background [0002] In recent years, as one of the indispensable basic components and equipment in the power system, the reactor has developed greatly under the impetus of technological progress. [0003] Air-core reactors have good effects in series connection, current limiting, filtering, parallel connection, etc., with good linearity and low noise. However, the range affected by the magnetic field is large, the electromagnetic radiation is serious, and electromagnetic pollution is caused; and the loss is large, the volume is large, and the cost is high. Iron core reactor has moderate linearity, low electromagnetic radiation, small loss, low cost, small size, and has a wide range of applications. [0004] At present, iron core reactors are mainly planar iron core reactors composed of three-phase column irons and upper ...
