◆ ZYS On-Load Tap Changer Oil Purifier
Application:
◆ Transformers with on-load voltage-regulating functions are widely used in power systems. 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.
◆ The device consists of five parts: filter element, oil pump, pipeline, PLC control system, and stainless steel box. Among them, the filter element is divided into two types: a impurity removal filter element and a water removal filter element: the impurity removal filter element is used to adsorb free carbon and degraded impurities, and the water removal filter element is used to remove moisture. The on-load tap changer oil purifier conforms to the transformer requirements of the “Code for Operation of Power Transformers” (DL / T572-95).
