Core Functions & Specifications

• Inverter Transformer Filter Function:

• Filtration Performance: Made of flame-retardant glass fiber (UL94 V0) with a multi-layer structure, capturing ≥99% of particles ≥2μm (dust, metal dust, oil mist) that enter the transformer cooling loop. Rated for 5–7 months of continuous use under standard industrial conditions (40°C, 50% humidity).

• Fit & Protection: Custom-sized for Robicon inverter transformers (compatible with models up to 2MW), featuring a rubber seal to prevent bypass leakage and a pressure differential indicator to alert when replacement is needed.

• Auxiliary Control Module Function:

• Signal Processing: Converts 0–10V analog signals (from transformer temperature sensors, voltage transducers) to digital data with ±0.2% accuracy, transmitting to the inverter controller in ≤12ms for real-time monitoring.

• Fault Management: Triggers pre-alarms for abnormal conditions (e.g., transformer over-temperature ≥120°C, voltage fluctuation ±10%), supporting integration with DCS systems for centralized fault diagnosis.

• Cross-Series Compatibility: Fully compatible with Siemens Robicon G5 and G6 series inverters (e.g., matching power units A5E42740246, A5E38977502), requiring no software debugging—directly replaces old components via plug-and-play design.

Application Scenarios

• Steel Mill Rolling Drives: Used as a transformer filter in Robicon inverters for hot rolling mills, blocking iron oxide dust from entering the transformer, which reduces transformer maintenance cycles from 1 year to 2.5 years.

• Power Plant Turbine Drives: Functions as a control module to monitor inverter transformer temperature, automatically adjusting cooling fan speed when temperature exceeds 80°C, avoiding turbine shutdowns caused by inverter overheating.

• Petrochemical Pump Drives: Serves as a dual-purpose spare part for crude oil transfer pump inverters—the filter blocks oil vapor, while the control module monitors voltage stability, preventing pump jams from voltage dips.
