Application | Vacuum Pumping System
The PureTech Vacuum Pumping System (Model VPS) is also called as Transformer Evacuation System, Vacuum Drying System and Transformer Vacuuming System, it is mainly used for vacuum drying of high voltage power transformers, and maintaining a high vacuum degree inside transformers before oil injection, it is a necessary equipment for installation and maintenance of power transformers.
Model VPS Vacuum Pumping System is comp osed of two-stage vacuum pumps (air-cooling rotary vane vacuum pump and roots booster pump), which can 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.
• Wide applications, applys to not only transformer evaucation, but also vacuum drying of tap changers, auxiliary switches, and other electrical equipment which needs vacuumizing.
• Portable type with compact structure, easy to operate and maintain.
• Multi self-protection settings protect the equipment from being damaged by sudden situations such as lack of phase, overvoltage or under-voltage, etc.
• Reliable performance, the components and electrical control components are from world famous brands, such as Leybold, Rietschle, Atlas, etc.
• Bulit-in filter to prevent particles from damaging the vacuum pumps.
• PLC automatic control and Fully touch screen is optional.
