Tips: How to select a line reactor?

The line reactor is the general name of the inductor and the reactance device. As inductor appeared earlier on the history of electrical equipment and was called line reactor, capacitor is also called reactance device. Common line reactors include the incoming line reactor, which is used to restrict the sudden voltage change and current impact caused by overvoltage. It can also smooth the spike pulse contained in the power supply voltage, thus improving power quality. Single phase DC line reactor is mainly used between the DC link and contravariant link in the inverter system, its main function is to limit the AC component superimposed on the DC current to a specified value. Main function of three-phase output line reactor is to compensate the influence of long line distributed capacitance, restrict the output of harmonic current and improve output high frequency impedance, thus protecting the inverter.

Common line reactors include the core-type line reactor. Such a line reactor has small size and low magnetic flux leakage, loss. It can be used in the high-voltage board. However, it also has many disadvantages, such as large noise, easy magnetic saturation (which may lead to burn out of coil), poor harmonic suppression and poor short circuit current resistant. Dry-type air core reactor has strong flow capacity, simple but tough mechanical structure, it can be used outside. However, it has disadvantages of high active power loss and large electromagnetic interference to surrounding electrical equipment . Moreover, half core-type reactor and magnetic shielding reactor are also common. Therefore, the converter has many types and functions, proper line reactors shall be selected by demands in actual power systems.
