The invention relates to the technical field of an electrician, and specifically relates an UHV (extra-high voltage) AC line electricity verification device. The electricity verification device comprises a wire, an energy taking device clamped on the wire, a power supply module fixedly arranged under the energy taking device and an electroluminescent material fixedly arranged under the power supply module, wherein the luminous surface of the electroluminescent material faces downward. The energy taking device and the power supply module are externally and respectively provided with a shielding layer, and the shielding layers are connected with the wire; the input end of the energy taking device is connected with the wire, and the output end thereof is connected with the input end of the power supply module and the ground; and the output end of the power supply module is connected with the input end of the electroluminescent material. The device realizes electricity verification on an UHV line, thereby preventing contact-type electricity verification done by workers, and saving a lot of manpower, material and financial resources; meanwhile, since the device is hung on the line, safety hidden trouble during electricity verification is eliminated; through an electromagnetic shielding mode, operation reliability of the device is ensured; and the device is low in cost, simple in structure, and convenient for batch production.
