Background

As is known, an ac reactor, whose main function is to resist interference, is generally installed at the inlet end of an electrical device in order to prevent "pollution" of the electrical network caused by higher harmonics generated by the electrical device in some ac circuits with higher voltages, and is formed by winding a three-phase coil around a three-phase iron core, where the coil has a sufficiently thick wire diameter, and is generally connected to a main circuit, so that a large current and a high voltage need to flow for a long time. The main consideration in the selection of ac reactors is the inductance, which is selected according to the fact that the voltage drop across the reactor cannot be greater than 3% of the rated voltage. For example, for a 30KW motor, the allowable current is 60A, so we choose that the inductance of the ac reactor should be 0.32 mH. However, if one of the three-phase coils in the existing ac reactor is damaged, the three-phase coils are inconvenient to maintain, and the normal use of the equipment is influenced.
