Abstract: Intrinsically safe power supply includes the 12V,15V,18V,24V power supply, and so on.the presence of existing test aging process complexity, low efficiency, low reliability . Domestic power supply for test and aging are not fully meet the requirements of the intrinsically safe power supply of automatic test aging.This paper presents an automatic test system for aging and intrinsically safe power supply and topology structure ,and was first set up in the automatic test system of mine intrinsically safe power supply and the aging.The system by PC, communication port and intrinsically safe power supply test aging equipment composition; the system platform with test function of 12V, 15V, 18V, 24V power supply, radio power a variety of intrinsically safe power supply aging; the automatic recognition system of different voltage grade of intrinsically safe power supply, automatic loading different power load, automatic early warning and analysis. The test proves that realizes the automation and intelligence of the test and aging of intrinsically safe power supply.
