Product Description

Variable-pressure vacuum drying equipment

Description of variable-pressure vacuum drying equipment
This kind of furnace adopts variable-pressure drying principle suggested by Dr. Moll from Germany, specialized for drying transformer and power capacitor bodies. Comparing to conventional vacuum heating drying method, drying duration of this variable-pressure type has been saved about 30-45%.

Application of variable-pressure vacuum drying equipment:

  • Drying transformer bodies in grade 10~110kV, capacity less than 100,000kVA
  • Drying transformer windings in 110~500kV grade
  • Drying current transformer and potential transformer bodies in 110~500kV grade
  • Drying power capacitors
  • Drying other electrical materials

Main features of variable-pressure vacuum drying equipment:

  • Compact structure, small occupation
  • High productivity: when drying one 110kV, 40000KVA transformer body, it will take only about 50 hours, close to that by kerosene vapor-phase drying equipment
  • Heating system is controlled by power control module, assuring even and stable temperature; Real power consumption during temperature-keeping is only about 35% of total power; There is no fluctuation of heating load and thus reduces actual heating power very much.
  • PLC control, high automation, more stable and reliable
  • Special baffle valves for vacuum drying, better vacuuming performance
