Vacuum Pump Unit For Drying Transformer
transformer oil purifier
Description

  VPS Vacuum Pump Unit is mainly used for drying transformer in various types of large-scale transformer installation and maintenance for high-efficiency vacuum drying. Quick air pumping, energy consumption, LCD display, mobile and flexible features. The leakage rate of the unit is less than 1%, the vacuum system is equipped with anti-oil-back device and phase sequence automatic commutation system to prevent the vacuum pump from reversing.


Features

1. Applying for vacuum drying and vacuum measurement of transformers, tap changers, auxiliary switches and other electrical equipment

2. Cooling type: natural air-cooled. The vacuum pump exhaust port is provided with device for condensing and collecting moisture.

3. The control system has the perfect protection and alarm functions with phase sequence, phase, overvoltage, under-voltage, leakage detection and protection of all faults are the corresponding warning light prompt.

4. Digital vacuum gauge are installed in the back of the total valve to facilitate the detection of the vacuum transformer.

5. Rotary vane pump and Roots pump separation of water vapor and light oil for cooling, collection and emissions, to protect the vacuum pump oil from pollution, enhance the pumping capacity of the vacuum pump to improve the working vacuum.
