The DRMBW20L 729-90066/13 3BHB009181P0001 Reactor is an inductive passive component specifically designed by ABB for industrial power systems. Its core functions include harmonic suppression, voltage stabilization, and reactive power compensation. It is highly compatible with ABB's power equipment such as the ACS series inverters (particularly suitable for the ACS 6000 medium-voltage inverter) and SVG (Static Var Generator), and is widely used in scenarios with strict power quality requirements, including new energy, intelligent manufacturing, and petrochemical industries. The net weight of this product is 21 kg.

Technical Characteristics and Performance Parameters

Core Technical Details

Inductance and Current Characteristics

• Rated Inductance: 20mH (±5% accuracy, measured at 25℃).
• Rated Operating Current: 60A (effective value).
• Overcurrent Withstand Capacity: It can withstand a short-term overload current of 120A (without overheating damage within 1 minute) and a peak current of 180A (within 0.1 second), which can cope with current surges during the start-stop of industrial loads (such as inrush current when the inverter starts).
• Temperature Stability of Inductance: The inductance value has excellent temperature stability. Within the operating temperature range of -20℃ to +120℃, the inductance drift is ≤3%, which prevents the attenuation of filtering and reactive power compensation effects caused by temperature changes and ensures the stability of power system parameters.

Loss and Efficiency

The reactor is wound with high-purity cold-rolled silicon steel sheets (model 30Q130, iron loss value 1.3W/kg @ 50Hz) and multi-strand enameled copper wires (conductor material: T2 red copper, conductivity ≥98%). Under rated working conditions:

• Iron loss ≤8W
• Copper loss ≤15W
• Total power loss ≤23W (far lower than the average loss of 35W of similar products in the industry)
• Operating efficiency ≥98.5%, which can reduce electric energy waste during long-term use.

Temperature Resistance and Environmental Adaptability

• Insulation Class: Class H (maximum allowable operating temperature 180℃).
• Winding Temperature Rise Limit: 100K (when the ambient temperature is 40℃, the maximum winding temperature ≤140℃). It has passed the 155℃/1000-hour thermal aging test and can operate stably in high-temperature industrial environments (such as metallurgical workshops and glass factories).
• Protection Class: IP20 (body). When matched with an outdoor protective cabinet (IP54 or above), it can withstand environments with a relative humidity of 95% (no condensation) and an altitude of ≤2000m. It also has salt spray resistance and mold resistance (complying with the IEC 60068-2-11 salt spray test standard), making it suitable for coastal and humid industrial scenarios.

Safety and Structural Design

• Insulation Safety: Double-layer insulating paper (material: NOMEX, temperature resistance 220℃) is used to isolate the winding and the iron core. The insulation resistance is ≥1000MΩ (measured at 500V DC), and the dielectric loss tangent value tanδ ≤0.005 (1kHz/25℃), which can resist the risk of insulation breakdown caused by grid voltage fluctuations.
• Overheating Protection: A temperature control switch is equipped (operation temperature 140℃, reset temperature 120℃). When the winding temperature exceeds the standard, the circuit is automatically cut off to prevent overheating and burning.
• Structural Reliability: The integral potting process is adopted (potting material: epoxy resin, thermal conductivity 0.8W/m·K), which enhances heat dissipation capacity and mechanical strength. The anti-vibration grade meets the IEC 60068-2-6 standard (10-500Hz, acceleration 50m/s²), and it can adapt to the vibration environment during the operation of industrial equipment (such as near machine tools and compressors).

Harmonic Suppression Capacity

For the 5th, 7th, and 11th harmonics generated by the inverter, the filtering attenuation rates are 45%, 38%, and 30% respectively. It can reduce the grid harmonic distortion rate (THD) from over 15% to below 5% (complying with the GB/T 14549-1993 Power Quality Standard), which avoids the interference of harmonics on precision equipment such as PLCs and sensors, and at the same time reduces the heat loss of transformers and cables caused by harmonics.
