A special junction pole for testing a capacitive current of a neutral point ungrounded system is used to solve a connection problem of a testing instrument and a neutral point of a system. The technical scheme is that the special junction pole for testing the capacitive current of the neutral point ungrounded system comprises a fuse, an insulation sleeve and an insulation pole, wherein a metal cap with a conductive contact is fixedly arranged at the upper end of the insulation sleeve, the lower end of the insulation sleeve is connected with the insulation pole in an abutting mode, a wiring bolt which horizontally penetrates through the insulation sleeve and a wiring nut which is matched with the wiring bolt are arranged at the lower end of the insulation sleeve, the fuse is arranged inside the insulation sleeve, the lower end of the fuse is pressed on the wiring bolt, and the upper end of the fuse is connected with the metal cap in an electric mode through a compressed spring. The special junction pole for testing the capacitive current of the neutral point ungrounded system is simple in structure, convenient to operate and reliable in work. Not only are accuracy and working efficiency of the tasting result improved, but also personal safety of staff is ensured.
