The transformer is an important electrical equipment in the power system. The insulating oil acts as a medium for transformer insulation and heat dissipation. It is closely related to various faults that may occur inside the transformer. The condition of the insulating oil will directly affect the safe and economic operation of the transformer. The Vacuum Transformer Oil Purification Machine is an ideal insulating oil purifier for oil treatment.

As various reasons, the transformer oil quality and properties are not up to standard, it needs to be purify to improve its quality. The main reasons for the failure are excessive water content, other impurities, hydrocarbon gases, etc.

When user choose Transformer Oil Purification Machine, according to different voltage levels of the transformer, user can choose single-stage vacuum transformer oil treatment machine and double stages high vacuum transformer insulating oil purifier.

Generally, the single stages vacuum Insulating Oil Purifier is used to purify the insulating oil of the low voltage transformer. The dielectric strength can reach 50-65KV after purification, which is suitable for the purification processing of most commonly used electrical insulating oil. Double Stages High Vacuum Transformer Insulating Oil Purifier is used to purify the main transformer oil of 110KV and above, and the oil can meet the oil standard after purification. For the insulating oil of transformer, influence of gas values such as acetylene, methane, hydrogen, and the influence of dielectric loss. And the gas content and water content of the transformer insulating oil be successfully reduced by purification process of Transformer Oil Treatment Machine, so that the dielectric strength of insulating oil is significantly improved, and the insulation performance is stable.

If it is considered that the transformer is already filled with oil and cannot be completely shut down and all the oil is drawn out for purification, so it is only do online filtration In addition, it can reduce equipment downtime, reduce maintenance labor intensity and operating costs, increase the service life and reliable operation rate of transformers, and adopt a small flow and low vacuum working method to prevent the possibility of oil current charging and gas action, and it has a good economic benefits and promotion value.

Online filtration of Vacuum Transformer Insulating Oil Purifier should meet the following conditions:

(1)If the heating temperature is too high, the characteristics of the oil will be damaged; if the temperature is too low, the water in the oil cannot be discharged, so the temperature and vacuum value should be controlled appropriately in the oil treatment process.

(2)During the operation of the online Transformer Oil Purification Machine, it is necessary to ensure that no oil flow is charged in the transformer, and there is no signal or trip accident caused by the action of the transformer's non-electrical protection device.

(3)The online Transformer Oil Treatment Machine can effectively isolate the oil circuit and alarm for power failure when there is abnormal voltage or oil leakage during the oil purification process. It has the function of remote operation status detection and control during the oil purification process.

(4)On-line Insulating Oil Purifier will not produce fault characteristic gas due to its own reasons.

(5)Transformer Oil Purification Machine can degas, dehydrate and remove impurities during the on-line oil filtration process, maintaining the good insulation properties and stability of the oil.
