    Why Should You Buy a Reactor?

    When a short circuit occurs in the power system, a large short-circuit current will be generated. If not limited, it is very difficult to maintain the dynamic stability and thermal stability of electrical equipment. Therefore, in order to meet the requirements of breaking capacity of some circuit breakers, reactors are often connected in series at the outgoing circuit breaker to increase the short-circuit impedance and limit the short-circuit current. Due to the use of reactor, the voltage drop on the reactor is large in case of short circuit, so it also plays a role in maintaining the bus voltage level. It makes the voltage fluctuation on the bus less and ensures the operation stability of user electrical equipment on the non fault line. This is how the reactor works.

    What are the Uses of the Reactor in Power System?

    Output line reactor is also called as the motor reactor. It is mainly used in the industrial automation system, especially occasions with frequency converter, to extend the valid transmission distance of the frequency converter, effectively restrain the transient high voltage in switching on/off the IGBT module of the frequency converter. It is suitable for compensating the distributed capacitance, restraining the output harmonic current, effectively protecting the frequency converter and improving the power factor, with an expectation to reduce the pollution of the harmonic current generated by the rectification unit to the power grid.

    Output Line Reactor Price List

    When selecting a output line reactor, its function shall be firstly determined, then the reactance ratio can be selected according to its functions, finally, the output line reactor capacity is selected according to the capacitor capacity (reactor capacity is equal to the capacitor capacity multiplied by reactance ratio). Selection of a reactor is complex, power grid quality and parameters, capacitor parameters shall be determined.
