In the power grid system, there are numerous harmonic sources such as rectifiers, converters, and frequency converters. The high-order harmonics they generate pose a serious threat to the safe operation of the main transformer and other electrical equipment within the system. To address this challenge, filter reactors are widely used in high and low-voltage filter cabinets. They work in series with filter capacitors and, by precisely tuning to specific resonant frequencies, effectively absorb harmonic currents of corresponding frequencies in the power grid. The reactance rate design is flexible, including options such as 1%, 5.67%, 6%, 12%, and 13%, which can effectively suppress the 3rd, 5th, 7th, 11th, 13th, and higher-order harmonics.
The core advantage of this filter reactor is that it not only significantly reduces harmonic interference in the power grid but also optimizes the system power factor, providing robust support for the safe and stable operation of the power grid. Specifically, this filter reactor features the following notable characteristics:
- Diverse Design: Available in both three-phase and single-phase types, all adopting iron-core dry-type designs to ensure great performance in various application scenarios.
- High-Quality Iron Core: Made from high-quality, low-loss cold-rolled silicon steel sheets. The iron core columns are meticulously segmented with epoxy laminated glass cloth boards, ensuring the reactor air gap remains stable during operation.
- Efficient Coils: Wound with F-grade or H-grade flat copper wire, the coils are tightly and uniformly arranged, effectively enhancing the overall performance of the reactor.
- Advanced Processing: The coils and iron core of the filter reactor undergo a series of meticulous processes, including pre-baking, vacuum impregnation, and heat curing. H-grade impregnating varnish is used to ensure the coils and iron core are tightly bonded, improving the durability and stability of the reactor.
- Quality Materials: The clamps, fasteners, and other components of the filter reactor are made from non-magnetic materials, ensuring a high-quality factor and great filtering effect.
- Anti-Corrosion Treatment: All exposed parts undergo strict anti-corrosion treatment, ensuring long-term stable operation even in harsh environments.
- Efficient and Energy-Saving: This filter reactor features low-temperature rise, low loss, high comprehensive utilization rate, and convenient installation.
