The invention belongs to the technical field of insulation measurement, and particularly relates to an insulator electrification detection device for an ultra-high voltage direct current transmissionline. The device comprises a mechanical arm 1, a mechanical arm 2, an insulated connecting rod, a rotating motor, a voltage detecting pin, a 24V lithium battery power supply, a power management module, a voltage divider resistance module, a voltage amplifier, an AD collecting module, a central processing module, a motor driving module, a communication module and a receiver. Under normal working conditions, the two mechanical arms are controlled to climb and turn over a tensile insulator string and a vertical insulator string, and in the condition without the influence of the current leakage, the insulation resistance detecting working of the insulator is completed by the voltage detecting pin and the detecting circuit module, and the data is in wireless transmission to a ground receiving party. The insulator elect
