Application
Necessary equipment of all utility and industrial customers is continued transformer maintenance, Aside from avoiding overvoltages, the primary process that promotes transformer longevity is oil reclamation. transformers require pure, clean oil to ensure dielectric strength and insulation properties.
Assen Enclosed type multi-function online vacuum power transformer oil purification machine is suitable for cleaning contaminated transformer oil, cable oil, and insulating oil, etc. Depending on the type of contamination equipment is designed using a combination of processes such as vacuum oil purifying, degasification, coalescing, and filtration. This machine is a perfect transformer oil maintenance equipment for power station and transformer manufacturer.
Features
1. Pre-Electromagnetic-valve before vacuum pump to prevent the vacuum oil flow backward.
2. Double-stage vacuum system, strong power of vacuum evacuating, ultimate vacuum value ≤ 5Pa
3. Two vacuum separating chambers, efficient oil film sprayer, increasing separating size and separating time to ensure the dry-level and dielectric strength improving greatly.
4. Duplex-Stereo film evaporation technology, combined with unique and advanced dewatering, degassing components, can rapidly and effectively separate water, gas from oil.
5. Adopt interlocked protective system, which connects the oil pump, heater, and liquid level sensor, avoiding blank heating, blank pumping, oil leak, and electricity leak. If there is any fault, the machine will be power off automatically.
6. Pre-gas-water separator before vacuum pump to prolong the vacuum pump and vacuum pump oil.
7. Double protecting system, Gas-water separator equips liquid level protector to prevent oil escape from vacuum pump
8. Optical oil foam detector and high oil level detector to prevent oil escape from the vacuum pump
9. Enclosed type to longer the service life of the machine and keep operation in bad weather condition
10. optional flow control mode, which allowed to change the flow rate by a frequency conveter
