JZ Small Online On-Load Tap Changer (OLTC) Transformer Oil Filtration Unit
On-load tap-changer online oil filtration unit is mainly used for bypass circulation filtering of transformer high-voltage switch. While the main system is running normally, the bypass circulation filter system effectively absorbs the trace moisture in the insulating oil and intercepts the fine mechanical particles, so as to control the cleanliness of the transformer oil and improve the insulation strength of the oil.
The on-load tap-changer online oil filtration machine is designed to ensure that the electrical, physical, and chemical indicators such as the moisture content, flash point, breakdown voltage, cleanliness of insulating oil will not be reduced. And the equipment can prolong the maintenance period of main equipment such as transformer high-voltage switches and the life of the transformer oil. It can also ensure the safe operation of the equipment during the maintenance period.
Functions of The Online On-load Tap-changer (OLTC) Transformer Oil Purification Machine
- The online on-load tap-changer (OLTC) transformer oil filtration machine can remove free carbon and metal debris during the normal operation of the transformer system, reducing the moisture content in the oil.
- It can ensure the breakdown voltage of the transformer oil and prolong the service life of the oil.
- It can improve the safety and reliability of the on-load tap-changer, thus prolonging the maintenance interval.
- The function of recovering transformer oil is realized.
Why You Need to Use An On-load Tap-changer (OLTC) Online Transformer Oil Purifier
About the on-load tap-changer transformer
To adapt to the voltage of large transformers, an on-load tap-changer is required to adjust the voltage of the transformer. The use of this tap-changer can greatly reduce the operating costs of the entire transformer, increase the availability of the transformer, eliminate the need for refueling and carbonization, and eliminate the need to replace contacts.
OLTC transformers are capable of regulating the system voltage while the transformer is in an energy state. It prevents negative effects caused by voltage variations by regulating low and high voltages.
After using the on-line oil filtration machine, the OLTC transformer does not require long-term maintenance.
About our company’s on-load tap-changer transformer oil filtration unit
The small online on-load tap-changer (OTLC) transformer oil filtration equipment produced by our company can ensure the safe operation of the relevant main electrical equipment during the maintenance period.
While the main system is running normally, the oil purifier can effectively absorb the trace moisture in the insulating oil through the bypass circulation filter system, intercept tiny mechanical particles, control the cleanliness of the insulating oil, and increase the insulation of the oil. It can prolong the maintenance cycle of transformer high-voltage switches, etc., and prolong the service life of transformer oil.
