Harmonic elimination and reactive power compensation equipment
The ZPFQ harmonic elimination and reactive power compensation device is our company’s solution developed specifically to address harmonic pollution caused by medium-frequency power supplies, thereby purifying the power grid. After more than ten years of dedicated effort, this technology has now reached maturity and is being mass-produced, seamlessly integrated into various models and specifications of medium- and high-frequency, as well as other nonlinear load systems.
Working Principle and Device Features
This device is primarily composed of a filtering capacitor, a filtering reactor, a circuit breaker, and a contactor (silicon-controlled rectifier) combined together. Connected in parallel with the harmonic source, the filtering device provides a low-impedance path for harmonic currents, allowing most of them to be directed into the filter. At the same time, it can supply reactive power back to the power grid, thereby reducing grid distortion and improving the power factor.
