The ZYD-M Mobile Type Double-stage vacuum transformer oil purifier plant/ oil filter/ oil purification/ oil treatment/ oil recondition system is designed for the following applications:
1. This transformer oil purifier machine is mainly used for purifying the insulating oil, transformer oil, mutual oil, switch oil, dielectric oil and so on.
2. This transformer oil purification machine adopts the double stages vacuum system, which can improve the machine working vacuum value highly, so it can remove the water, free water, trace water, gas and impurities in the contaminated transformer oil high-efficiently.
3. This transformer oil filter brings degassing, dehydration and removing impurities out of transformer oil fast and completely.
4. This transformer oil filtration system can also remove the acidity, sludge, free carbon, other soluble oil decay products and discoloration.
5. This transformer oil purifier can increase and maintain the oil's dielectric strength higher than 75KV, and insure the electrical devices running safely.
6. This transformer oil treatment can vacuum oiling to transformers, vacuum dry transformers and on-line operation with transformers.
Application scenarios
Substation on-site oil treatment
Applicable to on-site purification of transformer oil of 35kV, 110kV, 220kV, and even higher voltage levels.
Oil purification before commissioning of new transformers
Mobile equipment can be directly carried out on-site for vacuum degassing, water removal and impurity removal.
Oil regeneration maintenance of transformers in operation
Online treatment can be performed without interrupting equipment operation (powered bypass).
On-site oil sample detection and filtration
Can be equipped with oil testing instruments for simultaneous purification after detection.
Away from oil depots and inconvenient transportation areas
For example, in mountainous areas or temporary projects, mobility greatly improves the use efficiency.
Main functions
Function name Function description
Vacuum degassing Remove dissolved gas in transformer oil and improve the insulation strength of oil
Vacuum dehydration Remove free water, emulsified water and trace moisture to prevent oil deterioration and transformer moisture
Precision filtration Multi-stage filtration system can effectively remove solid particles, metal chips and impurities in oil to improve oil quality
Heating and temperature control Heat the oil at a constant temperature to improve the efficiency of dehydration and degassing
Online purification Allow bypass purification of running equipment without power outage, suitable for non-stop maintenance
Automatic control Equipped with PLC or intelligent control system to achieve automatic operation, fault alarm, safety interlock, etc.
Data recording Real-time recording of parameters such as temperature, pressure, vacuum degree, running time, etc. for easy maintenance and traceability
Easy to move Trailer-type or vehicle-mounted structure, with high-speed movement and rapid deployment capabilities, suitable for field and variable working conditions
