Reactor, doesn't it sound very professional? In fact, a reactor is a type of inductor that is responsible for regulating the inductance in a circuit. Inductors were invented as early as 1831, while capacitors were not introduced until 1874. So, a reactor is actually an inductor, which is commonly referred to as a reactor.
Construction of Reactor
Reactors are windings made by winding insulated wires, and there are two main types: hollow core reactors and iron core reactors. Hollow core reactors have a simple structure, while iron core reactors have larger inductance due to the addition of iron cores.
Types of reactors
There are many types of reactors, which can be classified according to their structure, connection method, and function. For example, according to the connection method, reactors can be divided into parallel reactors and series reactors.
The function of the reactor
- Reactive power compensation: In the power system, reactors can be used to compensate for reactive power, improve power factor, and reduce line losses.
- Filtering: In the power system, reactors can be used to filter out harmonics and protect equipment from harmonic interference.
- Suppressing inrush current: During motor start-up, the reactor can limit inrush current and protect the equipment from overload.
In short, reactors play an important role in power systems, not only improving system efficiency but also protecting equipment from damage. I hope this article can give you a deeper understanding of reactors!
