Detection device for non-repetitive transient large current

The non-repetitive transient large current detection device comprises a test power supply, a switch, a detected device and a current detection part, and is characterized in that the current detection part is composed of two diverters and a current transformer, each diverter is composed of a central disc, N main supporting rods and an auxiliary supporting rod, and N is larger than or equal to 4; the N main supporting rods are evenly distributed on the periphery of the central disc and connected with the central disc, the two auxiliary supporting rods are fixed to the tail end of each main supporting rod, the main wiring holes in the two separators are connected with a main line, and the branch wiring holes in the two separators are connected through branch lines. According to the current detection device provided by the utility model, the detected transient large current is amplified by 2N, so that the fusing instant large current of the detected device can be obtained, the awkward situation that no large curr
