▎ 摘　　要

NOVELTY - Device has a graphene heating film located on a glass surface of an observation window. A control switch controls a power supply part to supply power to the graphene heating film. A window glass is heat and observed using the current heating effect so as to reach the purpose of removing fog. The graphene heating film is connected with the power supply part through a lead. The control switch controls the power supply part to control the graphene heating film to work. The graphene heating film is located at an inner side of the observation window glass. The graphene heating film is adhered on a surface of the observation window glass by film sticking process. USE - Used as artificial climate chamber observation window demisting device based on graphene film. ADVANTAGE - The device achieves demisting of the observation window glass, and provides convenience for high voltage experiment of an insulator and other power elements under simulation of high humidity environment. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of the artificial climate chamber observation window demisting device based on graphene film (Drawing includes non-English language text).
