Reactor Introduction

The term reactor refers, in practical terms, to inductors that are extensively used in circuits. The reactor exhibits certain inductance due to electromagnetic induction in a circuit, which enables it to oppose the rate of change of current. When current passes through the conductor, it establishes a magnetic field in the space which the conductor occupies. Hence, inductance, in the general sense, works for any current-carrying conductor. The inductance of a straight conductor carrying current is very small since the strength of the magnetizing field is not pronounced. It is a proper reactor when it consists of a solenoid built up by winding a conductor, which is referred to as an air-core reactor. Sometimes to increase inductance, an iron core is inserted into this solenoid. It is then called an iron-core reactor. The two types of reactance are inductive reactance and capacitive reactance. The most common scientific nomenclature refers to them as inductors and capacitors, respectively. However, since the inductors came first in older texts with the name reactance, capacitors nowadays are referred to as capacitive reactance, while a reactor specifically means an inductor.

 Reactor Working Principle

A large short-circuit current will be generated in a power system during a short circuit. If this is allowed to go unrestricted, it becomes very difficult to maintain the dynamic stability and thermal stability of electrical equipment. Therefore, to help meet the breaking capacity requirement of some circuit breakers, a series reactor is connected at the outgoing circuit breakers to increase short-circuit impedance and limit the short-circuit current. With the reactors in place, during a short circuit, the voltage drop across the reactor will be fairly large, thus helping to maintain the bus voltage level, further limiting any voltage fluctuation on the bus, thereby ensuring the operational stability of user electrical equipment on non-faulty lines. 

The Structural characteristics of CKSG-0.3/0.45-6% Reactor

• The filtering reactors are of two types, three-phase and single-phase, both being iron core dry type.
• The iron core is constructed of high-quality, low-loss, imported cold-rolled oriented silicon steel sheets, in which the core column has been divided into uniform small sections through multiple air gaps. The air gaps are separated by epoxy laminated glass cloth plates and bonded with special adhesive to ensure that the reactance air gap does not change throughout operation.
• The coil is wound with H-grade or C-grade enameled flat copper wire, arranged tightly and evenly.
• After the assembly of the coil and iron core of the reactor into one unit, pre-drying, vacuum impregnation, and heat curing are carried out. H-grade impregnation paint serves to firmly bond the coil and iron core of the reactor.
• The clamps and fasteners of the reactor are made of non-magnetic materials to ensure a high quality factor and good filtering effect.
• All exposed elements are treated with anti-corrosion measures, while the outgoing terminal switch is fitted with tinned copper tube terminals.
