Description

Why purify transformer oil?
Dissolved gasses in transformer oil can cause arcing, coronadischarges, and overheating*-reducing the electrical efficiency andlifetime of the transformer. Likewise, water contamination at levels as lowas *0 ppm (parts per million) can adversely affect the insulating strengthof the oil. With ever-increasing standards for energy efficiency of powerdistribution transformers, the need to effectively degas will become evenmore important in the future. particles contamination will also affect thefunction of insulating oil. So we need to clean used transformer oil. 

Application:
Series ZYD Double-stage transformer oil purifier canquickly remove water, trace water, gas, particles as wellas acetylene, hydrogen, methane and other harmfulingredients from oil effectively to improve oil's dielectricstrength, effectively making sure electric equipmentsworking safely and normally. Series ZYD oil purifier isparticularly suitable for treating high-grade transformer oil,super-voltage transformer oil and new transformer oil. Itcan be used for filtration of more than **0V substation liveline work onsite. Meanwhile, Series ZYD oil purifier can beused as independent vacuum source with functions ofvacuum drying and vacuum oiling.

Features:
1. Double-stage vacuum system, strong power of vacuumevacuating, ultimate vacuum value 5Pa.
2. Two vacuum separating chambers, efficient oil filmsprayer, increasing separating size and separating time toensure the dry-level and dielectric strength improvinggreatly.
3. Duplex-Stereo film evaporation technology, combinedwith unique and advanced dewatering, degassingcomponents, can rapidly and effectively separate water,gas from oil.
4. Multi-stage precision filtration system, mesh filtrationcombined with molecular adsorption technologies.
5. Efficient electric heating system, heating uniformity, lesspower consumption, safe, and reliable.
6. Double-infrared liquid level sensor, pressure protectivesystem to ensure machine operation easy and safely.
7. Adopt interlocked protective system, which connect oilpump, heater and liquid level sensor, avoiding blankheating, blank pumping, oil leak and electricity leak. Ifthere is any fault, machine will be power off automatically.
8. Functions of live line work onsite, vacuum drying andvacuum oil filling.

Advantages:
Comparing with single stage transformer oil purifier,Series ZYD oil purifier can increase the effectivenessmore than three times, more quickly and completelydewater, degas, remove particles to get higher dielectricstrength. This equipment can be used as independentvacuum source with the functions of vacuum drying andvacuum oiling for the electric plants.
