Problems solved by technology
When electricity is used to store heat in the heat storage body during off-peak hours, heating cannot be stopped. In order to release heat at low temperature to prevent freezing of the pipe network, heat must be released while storing heat, which affects the effect of electric heat storage.

Description
technical field [0001] The invention relates to the technical field of electric heat storage energy, and more specifically, relates to a 900-volt electric heat storage energy device. Background technique [0002] Traditional clean energy heat storage heating equipment is composed of a single material and principle. In addition, the voltage level of electric heat storage is generally 10 kV and 0.4 kV. 10 kV electric heat storage equipment is suitable for super large heating area and the volume of heat storage body is limited by the installation area and power supply; 0.4 kV electric heat storage equipment has many heating wires, large amount of circuit electrical components and cables, and large current Such disadvantages as large heat loss and high cost are caused. The single principle of electric heat storage itself does not save energy, but saves money by using cheap electricity during off-peak hours. When electricity is used to store heat in the heat storage body during...
