1. Overview
The CKSC dry-type iron core series reactor is a critical component of reactive power compensation systems in power networks. When connected in series with power capacitors, it effectively:
- Suppresses high-order harmonics in the power grid
- Limits inrush currents and switching overvoltages
- Improves system voltage waveform
- Enhances grid power factor
This ensures the safe and reliable operation of power capacitors and other electrical equipment.
2. Model Description
3. Product Features
1. The reactor core is made of high-quality silicon steel sheets, with core columns divided into uniform segments by multiple air gaps. Gaps are insulated with epoxy laminate sheets to maintain stability over long-term operation.
2. Core end faces are bonded with silicone steel sheet adhesive, ensuring sheets are firmly held together, reducing noise, and providing moisture and dust resistance.
3. Coils are epoxy-cast and reinforced internally and externally with epoxy glass mesh, cast under vacuum using F-class epoxy system. This ensures excellent insulation, mechanical strength, and resistance to large current surges and thermal shocks.
4. Epoxy-cast coils are water-resistant with low partial discharge, allowing safe operation under harsh conditions.
5. Top and bottom ends of coils are equipped with epoxy pads and silicone rubber shock absorbers to reduce vibration during operation.
