Description
DVTP Series Double-stage Transformer Oil Filtering Machine is mainly used to improve the properties of insulation oil. It can remove trace water, gas, particulate matter, etc. from the insulating oil effectively and rapidly so as to boost the performance of transformers, circuit breakers, mutual inducts, cable, and capacitors which have insulation system. DVTP series specialize in purifying branded oil, insulating oil of high voltage and super high voltage transformer.
ASSEN Transformer Oil Filtering Machine is very effective, durable, and user-friendly with top-quality components and maintenance-free operation.
Features
Use ASSEN patented T model advanced degassing and dehydration system, built-in secondary evaporation barrier, which can increase the contact area of oil film, quickly separate water and gas in oil, and the efficiency is twice that of similar products
High-grade β precision filter material, the filter element is large in volume, better storage capacity and service life is long.
Short filtering process time, two-stage high vacuum and high pumping speed can quickly and efficiently remove the water vapor in the oil, so that the drying degree of the oil and the breakdown voltage value can be greatly improved.
Interlocked protection system which will avoid overload. over voltage, pumping without oil, heating without oil, oil leak, electricity leak and prevent any damages to equipment due to operating error or power failure.
After treatment,oil quality guarantees to the following specifications.

Why need an online transformer oil filtration unit?
The power transformer is the core equipment of the power system, the transformer oil as the insulation and cooling medium of the transformer, its performance directly determines whether the transformer can safely run. The main reason for the drop in oil dielectric strength value is the increase in the dielectric loss value and particles in the oil. The traditional treatment method is to take the transformer out of service and use a plate press oil filter unit to clean the transformer oil for 7 to 10 days, while the transformer oil needs to be heated to 65°C. As the plate and frame type pressure oil filter is an open structure, the oil filtering process is in contact with oxygen and the water and gas content in the oil increases significantly. However, this method of oil filtration takes a long time for the main transformer to go out of service, which seriously affects the availability of the main transformer and requires a lot of manpower and material resources. Therefore, there is a need to develop a device (online transformer oil filtration unit) that can filter oil with electricity to reduce the main transformer power outage time and reduce the cost of oil filtering.
