Description

Mobile Trailer-Mounted Disc Oil Separator for Transformer Oil Dehydration

This mobile disc oil separator is engineered for transformer insulating oil dehydration and purification at substation sites. The trailer-mounted design enables rapid deployment to multiple transformers without permanent installation, dramatically reducing maintenance costs for power utilities and industrial facilities. Combining vacuum-assisted centrifugal separation with integrated oil heating, this system achieves moisture removal below 10 ppm, restores dielectric strength to new-oil specifications, and removes dissolved gases and solid contaminants from mineral insulating oils.

Key Features

  • Mobile Trailer-Mounted Design: Complete system including centrifuge, vacuum pump, heaters, and filters mounted on a single-axle roadworthy trailer with DOT-compliant lighting for easy transport between substations
  • Vacuum-Assisted Dehydration: Integrated vacuum chamber reduces water boiling point, enabling low-temperature moisture removal that preserves oil additive packages and prevents thermal degradation
  • Dielectric Strength Recovery: Multi-stage purification process restores insulating oil dielectric strength to ≥ 70 kV (ASTM D877) and interfacial tension to ≥ 40 mN/m, exceeding IEEE C57.106 acceptance limits
  • Dissolved Gas Removal: Vacuum degassing chamber effectively removes dissolved acetylene, hydrogen, and other fault gases, improving DGA baseline for condition monitoring
  • PLC Automated Operation: Single-operator touch-screen control with automated sequence programming, data logging, and USB report export for maintenance documentation
