Description

Technical Field

[0001] The present invention relates to the technical field of solid electric heat storage, and in particular to a solid electric heat storage device that can simultaneously meet 110kV and 10kV voltage levels. Background Art

[0002] Solid electric thermal storage devices are used to store "valley electricity" in the form of heat. When needed, the heat is extracted through a heat exchanger for industrial and civilian use, such as industrial and civilian heating, equipment heating, etc., to achieve the purpose of rational use and energy conservation, reduce production costs, reduce harmful gas emissions from traditional heating, and reduce environmental pollution. When performing heat storage, the electric energy is stored after generating heat through the heating wire;
