Description

Introduction of HOPU transformer oil treatment plant

Vacuum dielectric oil treatment and filtering machine is mainly used to improve the properties of insulation oil for 110KV to 500KV project. It can remove trace water, gas, particulate matters etc. from the insulating oil effectively and rapidly so as to boost performance of transformers, circuit breakers, mutual inductors, cable and capacitors which has insulation system.ZYD series specialize in purifying branded oil, insulating oil of high voltage and super high voltage transformer. Additionally, it is suitable for treating low viscosity lubrication oil. Dissolved gasses in transformer oil can cause arcing, corona discharges, and overheating--reducing the electrical efficiency.

double stage high-efficient vacuum oil purifier is to remove free and dissolved water, gases, and mechanical impurities from insulating oils so as to ensure its purity and improve its insulation property. It is suitable for the application to oil treatment 500KV super-voltage transforming equipment and 220KV transformers. It is also suitable for the treatment of capacitor oil, transformer oil and freezer oil.

Transformer Oil Treatment Machine Features

1.The plant is delivered ready for operation.

2.Degassing, dehydration and filtering process if various kind of insulation oils in electrical transformers and circuit breakers through put in one or several passes

3. There are two vacuum pumps for plant ZYD (one is the vacuum pump, other one is the booster roots pump), which can improve the vacuum value highly. Making sure the water-content of the treated oil is less than 3 PPM.

4. All oil treatment plants, type ZYD are equipped with an automatic Anti-Foam Control System.

5. The plant is equipped with built-in control and safety devices, which provides for a maximum operating security.

6. Minimised power consumption through optimised degassing (excellent efficiency factor).

7. Standardized filter housing for 5 micron, 20 micron and 80 micron filter cartridges.

8. Automatic supervision of the degree of contamination of the fine filter cartridges

9. ZYD can evacuate the vacuum for the electric equipment separately, such as the transformer. Also it can be used to dry the electric equipment and input the oil into the electric equipment under the vacuum state.

10. The machine adopts the double-infrared liquid automatic controller, pressure automatic-protector which can make sure the machine works online for 150 hours continuously without person. So it is a reliable and high automatically machine.

11. Adopt interlocked protective system, which connect oil pump, heater and liquid level sensor, avoiding blank heating, blank pumping, oil leak and electricity leak. If there is any fault, machine will be power off automatically.

12. Functions of live line work on-site, vacuum drying and vacuum oiling
