Description

Load reactor

Technical Field

The invention relates to the technical field of power equipment, in particular to a load reactor.

Background

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 (inductor) and capacitive reactance (capacitor) are collectively called reactor, however, since the inductor is existed in the past and is called reactor, the capacitor is called reactor now, and the reactor is specially called inductor.
