HOPU newly launched ZYD series horizontal high vacuum transformer oil purifier is a key equipment to ensure the safe and reliable operation of transformers. It has the following important functions.
● Improving insulation performance: effectively removing suspended particles, moisture, and gas impurities in transformer oil, preventing arcing and breakdown, ensuring safe operation of transformers, maintaining good insulation performance, and improving reliability.
● Extending the lifespan of transformers: Regular oil filtration treatment can remove impurities and moisture from the oil, restore good performance, reduce the frequency of transformer replacement, and lower equipment maintenance and replacement costs.
● Reduce maintenance costs: timely filter out impurities and moisture, reduce internal sedimentation and corrosion, and lower equipment failure rates.
● HOPU New Breakthrough in Extreme Vacuum Extraction: woking vacuum can keep -0.1Mpa , improved 0.005 Mpa compared with before -0.095Mpa, significantly improved the efficiency of absolute vacuum degassing and dehydration. Even with such a high vacuum, there is no need to open the intake air valve, truly achieving absolute vacuum isolation from the outside world.
● HOPU 2025 New Automatic defoaming: The newly designed internal circulation eliminates foam, almost no air valve, automatically reduces the oil flow in and out and adds internal circulation pumps, so that the oil foam can be eliminated automaticallyBesides it also can be used as an independent vacuum drying unit and oil refilling machine for transformer and GIS device.
Features
The vacuum system uses the roots pump as the main pump and the rotary vane vacuum pump as the primary pump. Fast start-up, large pumping speed, stable performance, and high ultimate vacuum of less than 5Pa.
Double horizontal vacuum separators, combined with Duplex-Stereo film evaporation technology
Strong ability to remove impurities: ultra-large area cylindrical precision filter element, with high filtration accuracy, easy installation and replacement.
Low-load heating: Adopt advanced internal and external double-tube heat radiation indirect heating technology.
Automatic control to realize unattended, safe and stable working.
Safety interlock protection for oil pump, vacuum pump, heater,keep safely working
Low noise, easy operation, long maintenance interval, low energy consumption, low operating cost
It can be used together with the insulation oil regeneration device, which has the effect of decoloring, deacidification, deoxidation and removing free carbon and other harmful substances from the oil.
