Advantages
● Large-capacity three-dimensional flash evaporation design delivers efficient removal of moisture, dissolved gas and hydrocarbons to boost insulating oil performance.
● Graded multi-stage filtration system reliably captures solid contaminants and monitors filter condition.
● Supports energized online processing for transformers plus full suite of on-site vacuum operations.
● Integrated electrical interlock, phase-sequence protection and emergency stop modules deliver stable field safety.
● Automated temperature, liquid level and defoaming control enables unattended continuous running.
● Low-noise, energy-saving construction with long service intervals and swappable inlet/outlet ports to cut operating expenditure.
Application
ZJA Series Double-Stage Vacuum Transformer Oil Purifier serves power plants, substations, power utilities, transformer factories, metallurgy, petrochemical, machinery, railway and transportation sectors. It handles purification for new and aged transformer oil, imported oil and mutual inductor oil during UHV/110kV+ transformer installation and maintenance.
FAQ
Q: Can the purifier run while the transformer stays energized?
A: Yes, online purification can be carried out without shutting down the transformer, which shortens maintenance downtime.
Q: What custom optional upgrades are available for site-specific requirements?
A: Optional extras include PLC touch-screen control, water and particle content analyzers, smartphone cloud remote monitoring. We also offer mobile, stationary, trailer-mounted and fully enclosed structures. A three-stage vacuum variant is available for ultra-high vacuum requirements.
Q: What is the difference between double-stage and three-stage vacuum models?
A: The three-stage version achieves deeper ultimate vacuum, suited for projects requiring stricter degassing and dehydration standards. The standard two-stage model meets most 110kV ~ UHV routine oil purification demands.
Q: Can I customize power supply or adjust the equipment layout?
A: Power supply can be modified to match local grid specifications. We can also adjust piping and port layout to fit your existing site setup.
Q: How long is the typical service interval before routine maintenance?
A: The unit features long maintenance-free cycles. Service frequency depends on raw oil contamination levels and daily running hours. We provide operation manuals and on-site service guidance.
Q: What support do you provide after delivery?
A: We supply full operation manuals, remote technical guidance and optional on-site commissioning and training for field operators.
