Oil Immersed Transformer Vacuum Drying Oven

Kerosene vapor-phase vacuum drying equipment (KVPD) is mainly suitable for drying transformer bodies in super-high voltage than 110kV and big capacity.

Technical features of our kerosene vapor-phase vacuum drying equipment:

- It is equipped with build-in cascade evaporator, which can carry out distillation between two heating phases.

- There is an individual heat recovery device outside of tank, saving energy

- Water extraction quantity in each phase and total extraction amount can be recorded on time and displayed on computer screen. Water extraction curve of each intermediate pressure reduction phase and total water extraction amount curve can be drawn instantaneously. And water extraction rate of each intermediate pressure reduction phase can be calculated automatically.

- The flow of kerosene in the mixture of kerosene & water can be measured instantaneously and so the opening rate of the main control valve can  be controlled accurately, but not only rely on tank pressure control.

- The end point can be measured automatically by computer. The process will be cut off automatically when the temperature of work-pieces reaches 120°C±5°C, and tank pressure is less than 0.2mbar and water extraction rate is less than the set value.

- The whole process can be fully controlled automatically, and even can be operated unattended. The computer can monitor the process of product and display process parameters and curve of each phase. Various process curve and reports can be printed timely and backup automatically.

- Visible & audible alarm can be done automatically. And usual troubleshooting methods can be provided. Malfunction point and time can be recorded timely.

- Various parameters and the implementation state of program can be saved when power failure suddenly.

- Process parameters can be displayed and revised.
