Output Reactor

The Output Reactor is a highly engineered solution designed to optimize power delivery by minimizing harmonic distortion and stabilizing voltage in both high and low voltage systems. Its advanced, oil-free construction ensures precise output control and reliable, maintenance-free performance, making it ideal for critical industrial applications. By effectively reducing voltage fluctuations and electrical disturbances, the Output Reactor guarantees smooth, uninterrupted operation of sensitive equipment such as variable frequency drives (VFDs) and inverters. This powerful device enhances overall power quality, providing protection against harmful harmonics and ensuring system stability in demanding environments.

Product Components

Winding (Coil)
High-Frequency Design
Utilizes Litz wire or multi-stranded twisted conductors to minimize high-frequency eddy current losses.
Winding Method
Designed with multi-layer segmented winding or honeycomb structure to optimize distributed capacitance and inductance characteristics.
Insulation Treatment
Impregnated with epoxy resin or wrapped with polyimide film to enhance dielectric strength and thermal resistance (e.g., Class H or Class C insulation).

Magnetic Core (or Coreless Design)
Ferrite Core
Used in high-frequency filter output reactors to suppress harmonics at specific frequency bands (e.g., IGBT switching frequencies).
Air-Core Design
Coreless construction relies on self-inductance to prevent magnetic saturation, making it suitable for broadband suppression applications (e.g., dv/dt filtering).

Insulation and Shielding Structure
Interlayer Insulation
Uses mica tape or polyester film to isolate winding turns and reduce partial discharge risks.
Electromagnetic Shielding
Windings are wrapped with copper foil or aluminum casing to minimize electromagnetic interference (EMI/RFI).

Cooling System
Natural Air Cooling
Open-winding design or cooling fins to enhance convection heat dissipation.
Forced Air Cooling
High-power models incorporate built-in fans or external air ducts, with temperature rise control ≤50K.

Enclosure and Protection
Metal Enclosure
Constructed from aluminum alloy or galvanized steel plates, providing both mechanical strength and electromagnetic shielding.
Protection Rating
Ranges from IP20 (indoor) to IP55 (outdoor dustproof and waterproof), with some models filled with silicone gel for vibration resistance.

Connection Terminals
Low-Inductance Design
Features short-path copper busbars or bolt terminals to minimize parasitic inductance and improve high-frequency performance.
Insulated Bushings
High-voltage models use ceramic or silicone rubber bushings to isolate ground potential.

Monitoring and Protection (Optional)
Temperature Sensors
Real-time monitoring of winding temperature with system alarm linkage.
Overvoltage Protection
Integrated RC snubber circuits or varistors to absorb voltage spikes.
