The inspection personnel are difficult to see the safety status because of the position and angle of some high-voltage equipments in substation. And the potential safety hazards will bring a great threat to the safe operation of equipment. After the study and experiment the author proposed an inspection device which can carry out full-angle and close-range inspection for protential defects for operating equipment. The inspection device is made of insulating material equipped with remote control pneumatic lifting. It can capture the image of full angle and wirelessly transmit images to hand-held intelligent terminal

helping to inspect the high-voltage equipment with the full-angle and close-range view

which cannot be completed by the conventional method.
