The low-temperature rise harmonic filter circuit is composed of capacitor series reactor, which forms impedance under certain harmonic sequence to absorb a large amount of harmonic current. The quality of the capacitor will affect the harmonic filtering. Do you know the characteristics of the filter capacitor? Stable absorption effect. The service life of the capacitor is closely related to the temperature. The higher the temperature, the shorter the capacitor life and the lower the filter. Full film capacitor has the characteristics of low temperature rise, which can guarantee its service life. Low loss and tangent value of dielectric loss angle (TG uudelta): < 0.0003. Safety & according to GB and IEC standards, the internal single capacitor is equipped with protection device. When the line or single capacitor is abnormal, the protection device acts immediately and automatically cuts off the power supply to prevent leakage protection. Daily disasters. The additional discharge resistance can ensure the safety of power consumption and maintenance. The shell is stamped with steel plate, coated with high temperature coating inside and outside, with good weather resistance and safety. Convenient, light in volume, light in weight, convenient for loading, unloading and installation.
