Description

Unbalanced tap reactor

Technical Field

Background

The enlargement of the grid capacity allows the rating of the system short circuit capacity to be increased rapidly. The maximum three-symmetrical short-circuit current effective value is close to 50kA already at the low-voltage 35kV side of a 500kV substation. In order to limit the short-circuit current of the transmission line and protect the power equipment, a reactor must be installed, and the reactor can reduce the short-circuit current and keep the voltage of the system unchanged at the moment of short circuit. 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. The tap reactor is generally a reactor on which two or more than two inductors are arranged, corresponding voltage drops are different according to different inductance values, the current transformer is used for monitoring the current, and the inductance value of the reactor is adjusted.

The distance between the middle fixed joint of traditional reactor of taking a percentage is unified, and input point and reactance value output mode are single, inconvenient use, and the internal component is more, causes inside precision component to take place to rock easily when taking place vibrations for the part is not hard up, reduces work efficiency.
