Background
The artificial climate chamber is an important device applied to insulator high-voltage experiments, the insulator is placed in the artificial climate chamber and is applied with operating voltage, and researchers can manually control environmental parameters such as environmental humidity, air pressure and the like in the climate chamber so as to research the insulating property, pollution flashover characteristics and the like of the insulator under different environmental conditions. The artificial climate chamber belongs to a closed device and can not be opened randomly during operation in order to prevent the environmental parameters in the climate chamber from being changed accidentally. In order to prevent electric shock accidents, people are prohibited from staying in the climate chamber during operation. Therefore, during the experiment, the researchers can only observe the insulator in the climate chamber through the observation window. For experiments such as pollution insulator flashover and the like, high-environment humidity climates such as fine rain, dense fog and the like need to be simulated in a man-made climate chamber. Because the humidity in the climate chamber is high, the observation window is easy to generate the fogging phenomenon, and the observation of researchers and the recording of the running state of the insulator by the camera equipment are seriously influenced. The heating device is the most effective defogging method for the observation window glass, the prior technical means is to plate a layer of metal or metal oxide film on the glass surface as a heating layer, but the prior coating material generally has the problems of higher opacity and reflectivity, which can cause adverse effect on the definition of images.
Disclosure of Invention

The graphene film has good light transmission performance, the opacity of the single-layer graphene under white light irradiation is only (2.3 +/-0.1)%, and the reflectivity is less than 0.1%, so that the graphene film is obviously superior to the existing metal or metal oxide conductive film. Due to the excellent characteristics of the graphene film, the defogging device for the observation window of the artificial climate chamber based on the graphene film can be applied to multiple purposes such as human eye observation, image shooting and the like.

The graphene heating film is connected with the power supply part through a wire, and the power supply part is controlled by the control switch, so that the purpose of controlling the heating film to work is achieved. The graphene heating film can be positioned on the inner side of the observation window glass and also can be positioned on the outer side of the observation window glass. The graphene heating film can be adhered to the surface of the glass by adopting a film adhering process, and can also be formed on the surface of the glass by adopting a brushing, growing, film coating and depositing process.
