Advantages
● Adopts advanced dual-stage high-capacity dehydration & degassing design with large-area 3D flash evaporation technology to remove water, air and hydrocarbon impurities from insulating oil.
● High-grade core components ensure stable equipment performance.
● Humanized design featuring low noise, energy-saving operation and long maintenance intervals to cut operating costs.
● Multi-stage precision filtration system effectively traps solid particulate contaminants.
Application
This series is engineered for 500kV, 750kV, 1000kV AC power grids and ±660kV, ±800kV, ±1100kV DC power grids. It handles deep purification for new transformer oil, imported transformer oil, mutual inductor oil and UHV transformer oil, supporting on-site transformer maintenance, vacuum oil filling and vacuum drying operations.
FAQ
Q: Is this purifier suitable for unattended continuous operation overnight?
A: Yes. It supports fully automatic online operation. Built-in real-time status indicators, automatic temperature & liquid level control, defoaming and pressure protection maintain stable operation without continuous manual supervision.
Q: What safety protection mechanisms are integrated for field working conditions?
A: It comes with full safety protection: vacuum, pump and heating system electrical interlocks, emergency stop, overload & leakage protection, phase sequence and phase loss protection. The unit will auto shut down in case of sudden faults to protect operators and equipment.
Q: How can I know when the filter cartridges require replacement?
A: The multi-stage filtration system is fitted with self-inspection monitoring. It continuously detects contaminant accumulation and triggers an alarm once the filter cartridges need changing.
Q: What custom optional packages can be selected for different site projects?
A: Available options include PLC touch-screen control, online particle counters, flow meters, remote smart platforms for parameter adjustment and data logging, and VFD flow regulation. Structural variants include fixed, mobile, trailer-mounted, fully enclosed and containerized versions.
Q: Can the unit perform transformer and circuit breaker vacuum oil filling and transformer evacuation on site?
A: Yes. It is purpose-built for field maintenance and can complete vacuum oil filling for transformers & circuit breakers as well as transformer vacuum evacuation on location.
Q: What kind of insulating oil can this machine process?
A: It handles UHV transformer oil, mutual inductor oil, new insulating oil and imported transformer oil, and meets the purification requirements for UHV AC and DC power grid projects.
