High-Performance Reactor for Reactive Power Compensation Systems

The SVG dry-type iron core line reactor is an essential component in static var generator systems, designed to enhance power quality and ensure stable grid operation. Installed at the front end of the SVG device, it plays a critical role in connecting the inverter system to the power grid while improving overall system performance.

This reactor is widely used in reactive power compensation applications across industrial power systems, renewable energy plants, and utility networks, where efficient voltage regulation and harmonic control are required.

Core Functions

The line reactor provides energy buffering between the SVG device and the power grid, helping to stabilize system operation during dynamic load changes. It effectively reduces switching ripple from the SVG inverter and minimizes common-mode interference, improving electromagnetic compatibility.

It also suppresses sudden current changes when the inverter is connected to the grid, ensuring smooth current transition and protecting system components. In addition, the reactor can adjust grid voltage levels when necessary to match inverter operating requirements.

Technical Capability

We manufacture CKSC series SVG dry-type iron core line reactors with voltage ratings up to 35 kV, current ranges from 25 A to 1000 A, and inductance values above 0.6 mH. All parameters can be customized according to project specifications and system requirements.

Structural Design

The reactor consists of two main components: the iron core and the winding coil. The core adopts a three-column structure, with stepped or radial laminated core columns and rectangular or circular yokes. High-quality cold-rolled silicon steel sheets are used to ensure excellent magnetic performance and reduced core losses.

To minimize noise and vibration, the core is encapsulated with high-strength resin, and multiple segmented air gaps are incorporated to reduce magnetic flux density and operating noise. The core assembly is tightly fixed using low-magnetic fastening components, and vibration-damping materials are installed between the core and the base to enhance operational stability.

The coil is wound using copper or aluminum conductors insulated with high-grade materials. Transposition techniques are applied during winding to eliminate circulating currents, ensuring uniform current distribution. The coil is vacuum cast with epoxy resin, eliminating internal air gaps and significantly reducing partial discharge while improving insulation reliability.

Standards and Compliance

The reactor is designed and manufactured in accordance with GB/T 1094.6 for power reactors and NB/T 10289 technical specifications for iron core filter reactors used in high-voltage reactive power compensation systems.

Application Areas

SVG dry-type iron core line reactors are widely used in industries such as metallurgy, mining, petrochemical processing, renewable energy generation, and large-scale industrial plants. They are also essential in utility substations and power grids requiring harmonic suppression and voltage stabilization.
