ZYD-A PLC Fully Automatic Transformer Oil Filtration Machine

Application：
 
ZYD-A double-stage vacuum transformer oil purifier adopts Programmable Logic Controller (P.L.C) to achieve the automation of whole treatment process. It is a creative design introducing domestic and international advanced technology. It is applied to process transformer oil and insulating oil from power plant, power station, electric power company, power transmission equipment, transformers, industrial and mining enterprises, especially suitable for on-site installation, maintenance and purifying high level new oil, or running oil from big power transmission and distribution equipment and transformers on national main power transformation grid, which is above 110-750KV. It can shorten the oil treatment period for transformer installation and maintenance.
 
Features:
1.Equipped with PLC fully automatic control system. And it has double-stage high pumping speed vacuum system, multistage stage vacuum analytical separation system, it can quickly separate out water, gases, impurities, polar substances and other deteriorated materials.
2. Adopting the three-dimensional flash evaporation dehydration and degassing technology, it high efficiently separates water, gases from the oil, making the breakdown voltage rapidly increase to above 75KV.
3. Adopting the complex high speed degassing spiral flow structure, oil gas separate dual channel technology, redissolution technology in anti oil gas separation, it quickly removes various organic hydrocarbon gases, ensuring no acetylene and hydrogen in oil.
4. Adopting carbon fiber infrared heating, grouped ultra low surface load, PID constant temperature control and dual temperature flow protection technology. Inside the machine installed the the diameter increase oil flow direction turning overflow technology to prevent “dead oil area”, over-temperature and drying.
5. Adopting multistage high β value compound filtration system, linear coupling filter seal, it can effectively filter even the tiny particles mechanical impurities.
6. Specially made precise oil pump with low noise meeting environmental protection requirement.
7. Online filtering oil; with nobody watching is okay, and it can also be used for vacuum oiling the transformers etc and drying its hot oil.
8. Equipped with advanced infrared liquid level auto control system, auto defoaming control system, pressure protection system and safety interlock control to ensure that the equipment work for long time, safely and reliably.
