Abstract
A vacuum desorption, impregnation and curing system, a vacuum desorption device and a vacuum desorption process for a protective layer of a magnetic pole are provided. Before injection of an impregnation liquid, vacuum desorption is performed on a sealed system formed by a magnetic yoke and a vacuum bag. A functional relationship about a vacuum degree or pressure in the sealed system is established so as to control the procedure of the vacuum desorption. Parameters in the functional relationship include an average suctioned gas volume flow of a vacuum pump, duration of vacuumization, an initial pressure in the sealed system, as well as an initial volume of the sealed system. With the functional relationship for the vacuum impregnation and curing system and the vacuum impregnation and curing process, a vacuum desorption standard is provided, a desorption time may be grasped better, and mutual verification effect is formed in conjunction with the detected pressure.
