Product Description

Product Description

The current limiting reactor is connected in series with the power system to limit the short-circuit current when the  power system fails. When the line is short-circuited,  the current-limiting reactor uses its reactor characteristics to limit the short-circuit current of the line within a  certain limit,  so that the switchgear can remove the fault smoothly and effectively. Current-limiting reactors generally use air-core  reactors with better linearity of reactance value.
The current-limiting reactor can operate safely and reliably under  long-term rated current. In case of failure, its ampere-turns increase several times or dozens of times,  but its resistance or ability to limit short-circuit current cannot be reduced. Therefore,  the current limiting reactor should be made of hollow products instead of iron core products. The air-core reactor is an  inductive high-voltage electrical appliance used in the power system to limit short-circuit current,  reactive power compensation and equal shifting. The magnetic flux forms a loop through the air,  so it is called an air-core reactor. If the rated voltage and supply voltage of squirrel-cage AC three-phase  asynchronous motor are the same,  an air-core reactor with the same number of turns as the motor can be connected in series between the motor and the  incoming power supply to increase the inductance value and control the starting current not to be too high.
Hollow  reactors are mainly divided into hollow series reactors, hollow filter reactors, hollow shunt reactors, hollow current limiting reactors, hollow split reactors, hollow starting reactors, etc.,  which are often used for reactive power compensation, harmonic filtering, current limiting and other occasions.

Fields of application

The reactor is mainly used in the power system, to adjust the reactive power distribution in the system, reduce the power frequency voltage, and suppress the harmonic current and flicker. The following are some common applications: 

 1. In the power system: The reactor plays the role of regulating the reactive power in the power system, which can improve the stability of the system. For example, installing a parallel reactor in a transmission line can balance the reactive power and reduce line loss; installing a series reactor in a transformer can reduce the no-load current and extend the life of the equipment. 
  
 2. In the motor system: the reactor can be used during the starting and braking of the motor to reduce the starting current and the impact current during the braking process. In addition, it can also be used to prevent the self-excited magnetic phenomenon of the motor under light or no-load. 
  
 3. In electronic equipment and communication systems: reactors can be used to suppress the high-order harmonic components in the power supply and reduce the impact on electronic equipment. For example, high-frequency reactors are used in switching power supplies, inverters, communication equipment, etc.
