Widely used in low-voltage power distribution systems in industries such as power systems, electrified railways, metallurgy, chemical industry, and petroleum, as well as in occasions where harmonic suppression and power factor improvement are required.
Q
What is a CKSG low-voltage series reactor and what is it used for?
A CKSG low-voltage series reactor is an inductive component connected in series with capacitor banks in low-voltage power distribution systems. It is primarily used to suppress harmonic amplification, limit inrush current, and improve the overall power factor and voltage quality of the system.
Q
What materials are used in the construction of CKSG reactors?
CKSG reactors use a dry-core structure with high-quality, low-loss silicon steel sheets for the core. The coil is wound with enameled flat wire using F- or H-grade insulation materials, ensuring durability and high thermal performance.
Q
How does a CKSG reactor suppress harmonics in a power system?
Nonlinear loads such as frequency converters and rectifiers generate harmonics that can resonate within capacitor and transformer circuits. By connecting a CKSG reactor in series with the capacitor circuit, the resonant frequency is shifted away from dominant harmonic frequencies, effectively preventing amplification and reducing harmonic pollution.
Q
Does the CKSG reactor offer over-temperature protection?
Yes. Some CKSG reactor models are equipped with built-in over-temperature protection, typically activating at temperatures between 170°C and 180°C. This feature helps prevent damage from overheating and ensures safe, reliable long-term operation.
Q
In which industries are CKSG low-voltage reactors commonly applied?
CKSG reactors are widely used across multiple industries including power systems, electrified railways, metallurgy, chemical processing, and petroleum. They are suitable for any application requiring harmonic suppression and power factor correction in low-voltage distribution networks.
Q
What manufacturing process ensures the quality and reliability of CKSG reactors?
CKSG reactors undergo vacuum impregnation and heat curing processes, which create a strong bond between the coil and core. This process reduces operational noise, improves heat resistance, and ensures excellent heat dissipation. The entire structure also uses vacuum overpressure injected insulation material for enhanced reliability.
