Product Introduction
Series Reactor - Professional Power Quality Solution
Product Introduction
When you need reliable power quality management in your electrical systems, our Series Reactor delivers exceptional performance and protection. This advanced inductive electrical component connects in series between your power sources and load equipment, providing crucial reactive impedance to buffer electrical disturbances. Our Series Reactor effectively suppresses excessive inrush currents, filters high-order harmonics, and limits short-circuit fault currents to protect your valuable equipment.
The coil is made of epoxy resin vacuum casting, after high temperature curing. This advanced manufacturing process ensures superior durability and performance. The coil insulation performance is good, high mechanical strength, and the ability after glass fiber reinforcement helps it withstand large current shock and thermal cycling. Additionally, the moistureproof performance is excellent, making it suitable for various environmental conditions.

Main Features and Advantages
Superior Magnetic Linearity: Our reactors maintain excellent linearity where inductance remains stable even under fault current conditions, preventing magnetic saturation.
Advanced Insulation System: Features Class F or H insulation with epoxy resin impregnation, offering superior resistance to moisture, pollution, and partial discharge.
High Current Handling Capacity: Designed to withstand dynamic mechanical forces from short-circuit currents, rated up to 25kA or 50kA for specified durations.
Optimized Q-Factor: Engineered for high Quality Factor to minimize active power losses while maximizing reactive efficiency.
Robust Construction: Glass fiber reinforcement provides exceptional mechanical strength and impact resistance.
Practical Applications
Reactive Power Compensation: In industrial plants using Power Factor Correction capacitor banks, our reactors connect to capacitors forming detuned circuits. This prevents capacitors from acting as harmonic current sinks.
Short-Circuit Current Limiting: Utilities install these reactors on outgoing feeders or bus ties in substations to add impedance during downstream faults.
Electric Arc Furnace Stabilization: In metallurgy applications, they smooth erratic current consumption, stabilize arcs, and reduce grid flicker.
Harmonic Filtering: Effectively filters 5th and 7th harmonics to prevent resonance amplification in your power systems.
How It Works
Your Series Reactor operates by introducing controlled reactive impedance into the electrical circuit. When connected in series with capacitor banks, it creates a detuned filter that prevents harmonic resonance. During fault conditions, the reactor limits current magnitude to levels that standard circuit breakers can safely interrupt. The air-gapped iron core design ensures linear performance across varying load conditions.

FAQ
Q: What's the difference between Air-Core and Iron-Core reactors?
A: Air-Core reactors offer linear characteristics without magnetic saturation but require more space. Iron-Core reactors are compact with contained magnetic fields but may saturate at high currents.
Q: How do I choose the correct reactance ratio?
A: The ratio depends on your system's dominant harmonics. A 7% reactor works well for 5th harmonics and above, while 14% handles significant 3rd harmonic content.
Q: Can these reactors operate outdoors?
A: Yes, our outdoor-rated units feature UV-resistant epoxy casting and appropriate insulation for weather resistance.
Q: What maintenance is required?
A: Minimal maintenance includes periodic visual inspection, connection torque checks, and dust removal for optimal cooling.
