What are the application ranges of output reactors?

Output reactors are critical devices used in power systems to enhance performance and protect equipment. The following are the main characteristics and usage guidelines for output reactors:

ApplicationRanges

●Applicable for Reactive Power Compensation and Harmonic Mitigation:

Output reactors are primarily used in power systems for reactive power compensation and harmonic mitigation. By providing appropriate reactance, they effectively regulate the reactive power within the system,optimizing the power factor. Additionally, output reactors can filter or suppress harmonics generated by loads or power electronic devices, reducing their impact on the system and ensuring the normal operation of equipment.

●Compensate for the Effects of Long-Line Distributed Capacitance:

The primary function of output reactors is to compensate for the effects of distributed capacitance in long cable lines. In long-distance cable lines, the distributed capacitance of the cables can affect the power system, including generating undesirable currents and reducing system stability. Output reactorsprovide reactance that can effectively counteract the effects of cable distributed capacitance, mitigating its negative impact on the power system.

●Suppress Output Harmonic Currents:

Output reactors have the function of suppressing output harmonic currents. In the connection lines between variable frequency drives (VFDs) and motors, harmonic currents may be generated due to the operating characteristics of the VFDs. Output reactors effectively suppress these harmonic currents, reducing their pollution on the power grid and protecting the normal operation of VFDs and motors. By lowering harmonic currents, output reactors also improve the power quality of the system and extend the lifespan of the equipment.

●Effectively Protect VFDs and Improve Power Factor:

Output reactors can effectively protect VFDs from grid disturbances and harmonic currents. VFDs, as key components in modern power systems, are susceptible to external grid disturbances and harmonic currents, which can lead to performance degradation or failure. Output reactors provide reactance and filtering, safeguarding VFDs from these disturbances while improving the system's power factor, enhancing overall system efficiency and stability.

●Reduce Harmonic Pollution from Rectifier Units:

In power systems, rectifier units typically generate certain harmonic currents that can pollute the grid. Output reactors effectively suppress these harmonic currents, reducing their negative impact on the grid and thus lowering harmonic pollution. This improves the operational quality of the power system.

Usage Instructions:

To optimize the performance of output reactors and protect the power system, it is recommended to useappropriately sized cables between VFDs and motors, increasing the insulation strength of the cables. Non-shielded cables are suggested to enhance overall system reliability. Proper cable selection and insulation treatment can significantly improve the system's resistance to interference, ensuring that the output reactor performs at its best.
