It’s significant to determine the dust-proof level of enclosure for describing the reliability of electrical apparatus under dusty environment. This paper illustrated the dust-proof standard currently in effect and discussed related design problems of vacuum-pumping system. A new vacuum-pumping device was developed which can achieve remote control and change the parameters of pressure and flow. Therefore, the reliability and usability of dust-proof determination are greatly improved.
