摘　　要：简要介绍了变压器真空汽相干燥技术的用途、工作原理、设备组成和工艺流程,针对国内变压器真空汽相干燥工艺过程缺少理论依据的问题,较详细地叙述了作者所建立的反映变压器真空汽相干燥工艺过程热质传递规律的综合数学模型,说明其建模原理和模型功能。最后介绍了该模型在设备设计、过程模拟及工艺过程控制方面的应用。Application, working principle, equipment and technological process of a vapor-phase drying （VPD） of electric power transformer are introduced in brief. In view of the fact that the theoretical study on VPD is rather limited, a complex mathematical model for the mass and heat transfer process in VPDs was developed in this work. The principle and function of the model were described in detail. Applications of this model in equipment design, process simulation and process control were given at last.
