Embodiment Construction
[0019] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings; it should be noted that the embodiments are illustrative, not restrictive, and cannot limit the protection scope of the present invention.
[0020] A method for local heating and heat preservation and anti-condensation of the cold surface of the switch cabinet. The cold surface of the switch cabinet is obtained through thermal and moisture analysis, that is, the surface with low temperature and easy to generate condensation; the heater is placed inside the switch cabinet close to the cold surface The cold surface is heated at the position of the cold surface; an insulating material layer with a small thermal conductivity is arranged on the outer surface of the cold surface to reduce the heat exchange between the cold surface and the external environment, and further increase the temperature of the cold surface. The thermal insulation material layer ad...
