The invention discloses an intelligent test device used for a gas insulated switchgear (GIS) partial discharge test. The intelligent test device used for the GIS partial discharge test is formed by sequential connection of a control box (1), an inflatable non-partial-discharge transformer (4), a high-voltage rectifying device (5), a high-voltage protective resistor (6), a high-voltage electrode assembly (13) and a filter capacitor (19). Support devices are arranged under the high-voltage rectifying device (5) and the high-voltage protective resistor (6) and serve as supports. Each support device (7) is composed of a base (8), idler wheels (9), a triangular supporting rod (10), a perpendicular telescopic supporting rod (11) and a buckle (12). The idler wheels are located at the bottom of the base, the triangle supporting rod is fixed on the base, the perpendicular telescopic supporting rod is connected on the triangle supporting rod, and the buckle is connected with the perpendicular telescopic supporting rod high-voltage rectifying device or the high-voltage protective resistor. The high-voltage electrode assembly (13) is composed of a high-voltage electrode (14), a base (18), a grounding electrode (15), a test product room (17) and a grounding ring (16). The high-voltage electrode is arranged at the top of the high-voltage electrode assembly, the grounding electrode is arranged between the high-voltage electrode and the base, the test product room is fixed on the grounding electrode and the grounding ring is connected at the bottom of the test product room. The intelligent test device used for the GIS partial discharge test has the advantages of being easy to operate and install and convenient to carry.
