Onload Tap Changer Online Oil Filter Device Small Transformer Switch Oil Purifier
While on-load voltage-regulating devices bring convenience to voltage adjustment, they also add trouble to the maintenance of transformers. Frequent voltage regulation by voltage-regulating devices has accelerated The reduction of the insulating oil performance of the pressure regulating device will seriously endanger the safety of the on-load voltage regulating device in severe cases. ZYS On-Load Tap Changer Oil Purifier is mainly used for bypass circulating filtering of transformer on-load tap-changer. This device is used in conjunction with transformer on-load tap-changer, and can effectively remove the trace water, metal particles and other impurities from insulating oil in the on-load tap-changer under normal operation of the transformer system, to ensure the breakdown voltage and service life of the oil, reduce the number of power failure inspections, and effectively improve the safety and reliability of the on-load tap-changer. Our company's products are strictly manufactured according to the Ministry of Machinery Industry JB / T5285-2008 standard and the Ministry of Electric Power Industry DL / T521-2006 standard. After using the on-line tap-changer insulating oil online oil purification device, the cleanliness of the insulating oil can reach NAS3 - level 4.

◆ PLC intelligent control, online automatic operation, extending the switch maintenance cycle and reducing the number of power failure of the transformer.
◆ Reliable electric control loop and safety protection system.
◆ The dehydration and impurity removal filter adopts imported brands, which can effectively absorb impurities and remove moisture.
◆ Automatic alarm for filter element failure or blockage, support remote control and monitoring.
◆ The entire stainless control box, oil pipe, flange and flange bolts are made of 304 stainless steel, which is
corrosion-resistant and waterproof to IP55 or higher.
