真空——热风干燥技术和设备

the Technology and Equipment Description of Vacuum-hot Air Drier

真空热风干燥简称ＶＤＨ，它是应用于电工行业中的一种新兴工艺技术。本文介绍其工作原理和应用，即把被干燥的工件放于密闭容器中加热，同时进行热风循环，完后再抽真空，除去工件中的水份，以此达到干燥目的。同时介绍电压互感器器身ＶＤＨ的工艺及其相关设备。

Vacuum-hot air drier (abbreviated as VDH) is one of the modern technique used in the line of electrical engineering. This paper introduces its principle and application i. e. putting the machine partsto be dried in the closed vessel. Heating with circled hot air and then pumping in order to remove the water contained in it.So as to keep it dry. This paper also introduces the technique and relative equipment of the VDH transformer.
