Aiming at the problems of many output circuits and complex current regulation in the temperature rise test of low-voltage complete sets of switches, a three-branch outgoing circuit is designed by the current inverted input method to meet the stable output of three-phase 800 A, 630 A and 400 A currents, which solves the problems of difficult adjustment and poor stability of the test current, and realizes the uniform and stable output of the temperature rise test current.
