Description

technical field [0001] The invention relates to a reactor, in particular to a transformer type magnetron reactor. Background technique [0002] In the prior art, the magnetically controlled reactor type dynamic reactive power compensation device is composed of a magnetically controlled reactor branch and a passive filter branch (FC) connected in parallel, and the output reactive power of the device is realized by adjusting the output capacity of the magnetically controlled reactor. Continuously adjustable. Generally, the filtering branch is composed of passive device capacitors and filter reactors, which are designed as filters of different orders, and the filtering ability is limited. The active filter (APF) has better filtering characteristics, but when the active filter (APF) is connected to the high-voltage system, it is generally connected through a transformer. The transformer type magnetic control reactor solves the problem that the active filter (APF) or other equi...
