Electrothermal aging test device of cross-linked polyethylene cable accessory

The utility model discloses an electrothermal aging test device of a cross-linked polyethylene cable accessory. The electrothermal aging test device of the cross-linked polyethylene cable accessory is characterized in that the test device comprises three functional parts of a high voltage introducing unit (1), a test circuit unit (2) and a large current generation unit (3); the high voltage generation unit (1) is connected with the test circuit unit (2), so that high voltage is introduced into a test circuit; the test circuit unit (2) passes through the large current generation unit (3), so that magnetic field coupling is formed and high current is generated; and the high voltage introducing unit and the large current generation unit work at the same time, so that the purposes of high voltage applying and large current passing in the test circuit unit are realized.
