Reactors, also called inductors, are electrical conductors that, when energized, generate a magnetic field in a certain spatial area occupied by a conductor, so that all electrical conductors capable of carrying current are inductive in the general sense. However, the inductance of the electrified long straight conductor is small, and the generated magnetic field is not strong, so that the actual reactor is in a mode that a conducting wire is wound into a solenoid, and is called as an air-core reactor; in order to make this solenoid have a larger inductance, a core, called a core reactor, is sometimes inserted into the solenoid. Reactance is divided into inductive reactance and capacitive reactance, and the more scientific classification is that inductive reactance ware (inductor) and capacitive reactance ware (capacitor) are called the reactor collectively, however since the inductor has been existed in the past, and is called the reactor, so people say that the capacitor is exactly the reactor, and the reactor is specifically referred to the inductor, has a large amount of harmonic sources such as rectification, current conversion, frequency conversion device in the electric wire netting, and its higher harmonic that produces can seriously harm the safe operation of main transformer and other electrical equipment in the system. The filter reactor is widely used in high-voltage and low-voltage filter cabinets, is connected with a filter capacitor in series, is tuned to a certain resonant frequency, is used for absorbing harmonic current of corresponding frequency in a power grid, has the reactance rate of 1%, 5.67%, 6%, 12%, 13% and the like, and can eliminate 3, 5, 7, 11, 13 and higher harmonics.
