PLC touch sreen type vacuum Transformer Oil Dehydration system plant

Moisture within a transformer can lead to premature aging, can increase the rate paper decay and lead to the dielectric failure in extreme cases.  Assen Transformer Oil Dehydration system plant will reduce the moisture content of transformer oil and windings.   A dehydration treatment can be conducted via a hot oil dry-out or a high vacuum dry-out.

1. Two pumps: Vacuum pump and booster pump 
2. Three-stage filter system 
3. Z-shape Heater to make the heating uniformity 
4. Installing oil-level floating ball and double-infrared liquid level automatic controller to control the oil level 
5. Foam sensor to avoid oil leaking 
6. Temperature Controller to protect the machine 
7. Suitable oil filtration machine for high voltage transformer 
8. Large filtration area, high capacity of holding impurities 
9. Two vacuum separator to increase separating size and time and ensure the drying degree and improve dielectric strength which is higher than 75 KV. 
10. Doing online oil purification of substations over 110 KV. 
11. Independent function of vacuum oil filling and drying. 
12. Duplex stereo flash evaporation technology 
13. Equipped with pressure protective system and interlocked protective system to connect oil pump, heater and liquid level controller. If there has any fault, this oil filter will be power off automatically. 
14. Saving energy and time 

To handle electrical stresses, transformer oils are required to have better dielectric strength. Lower residual water, gas and contamination content must be maintained to reduce the speed of oil ageing. All of these operations are performed using the transformer oil filtration equipment.

ASSEN ZYD transformer oil filtration, dehydrating and degassing can be performed individually or simultaneously based on the various conditions of the mineral oil and customer requirements.

Transformer Oil Dehydraion Plant's Technical Data:

Structure Chart:

The oil technical data after treatment:

• Gas content less than 0.1%
• Impurity size less than 1μm without free carbon
• Oil dielectric strength (breakdown voltage) more than 75KV
• Acidity value less than 0.01 mgKOH/g
• Dielectric loss factors at 90°C less than 0.001

Transformer Oil Dehydration Plant's Advantage:
Comparing with the single-stage vacuum oil purifier, this machine can dewater, degas and removes the impurities more quickly, more completely, and makes the oil BDV (Breakdown Voltage) of 75kV or higher. As the bridge-type vacuum linking system that can purify and also can be an independent vacuum power supply, this machine can treat the electric insulation devices.

Q: How can we achieve drying without elevated heating of the insulation material for transformers?
A: Drying of insulation materials can be achieved at low temperature and low pressure levels. The pressure levels and temperature levels for drying vary for distinct material. At low pressure or under vacuum the rate of water vapour evaporation is accelerated if sufficient heat is provided to the insulation material. Thus we can achieve a good drying of insulating material if the material is suitably heated and subjected to vacuum.
