Application Scope:

Vapor Phase Drying (VPD) plant with oil spray function is mainly applied for drying (under vacuum state) UHV transformer(110kV-1100kV). System can start vacuum oil spray function when drying phase ended, help make insulation level of product under stable in a certain time.

Characteristics:

The working principle of VPD plant is: kerosene is heated and evaporated under vacuum state and becomes high-temperature kerosene vapor. Kerosene vapor will be condensed when contacts with the lower-temperature products so as to release latent heat to heat up the products. The condensed kerosene (liquid state) will be collected and returned to evaporator where it is evaporated again and repeats above steps for several times. As a result, temperature of product is rising continuously, the moisture in products are also evaporated out and the water vapor will be pumped out of autoclave by vacuum system to achieve a thorough drying.

Heat exchange efficiency of VPD plant is higher than that of any other heating methods; its drying performance is very stable, which is the first choice for drying high-voltage insulation products at present.

Our vapor phase drying plant is developed by introducing and absorbing the foreign advanced technology, VPD with oil spraying function is specially suitable for UHV and EHV transformer.

now it has been successfully used by many well-know companies, such as: Siemens, ALSTOM, State Grid Corporation of China, TBEA Co., Ltd., etc.

≤Industrial Standard of Vapor Phase Drying Plant: JB/T11056-2010≥ was hosted and draw up by Kaixuan in 2010.

Successful Project Example(s):

Siemens transformer(Russia)
