Application | Transformer Evacuation System
The PureTech Vacuum Transformer Evacuation System (Model VPS) is also called as Vacuum Pumping System and Vacuum Drying System. This system is used for exhausting and dehumidifying a transformer before filling insulating oil in it. It performs vacuum drying of high voltage power transformers, and maintaining a high vacuum degree inside transformers, it is a necessary equipment for installation and maintenance of power transformers.
Model VPS Transformer Evacuation System is designed with combination of two-stage high-efficient vacuum pumping system (air-cooling rotary vane vacuum pump and roots booster pump), to handle large volumes of moisture in transformer's tank, and achieve a working vacuum of 10 Pa and a limit vacuum degree up to 1 Pa. This system is a one-click start type, which can be started quickly, furthermore, it has a stable working performance, as well as a powerful vacuum pumping capacity. It adopts a digital intelligent system and vacuum testing instruments, easy to operate and monitor.
Vacuum Pumping System is used for vacuum transformer drying while oil injection is in progress after purification. Therefore, the efficiency of installing and maintaining the transformers is greatly improved.
