Description

A reactor testing device and its operation method

technical field

The invention relates to a reactor testing device and an operation method thereof.

Background technique

Reactors are also called inductors. When a conductor is energized, a magnetic field will be generated in a certain space occupied by it, so all current-carrying electrical conductors are inductive in a general sense. However, the inductance of the energized long straight conductor is small, and the generated magnetic field is not strong, so the actual reactor is the wire wound into the form of a solenoid, which is called an air-core reactor; sometimes in order to make the solenoid have a larger inductance, The iron core is inserted into the solenoid, which is called iron core reactor. Reactance is divided into inductive reactance and capacitive reactance. The more scientific classification is that inductors (inductors) and capacitors (capacitors) are collectively referred to as reactors. However, since there were inductors in the past, they were called reactors. So now what people call a capacitor is a capacitive reactor, and a reactor refers specifically to an inductor.
