Problems solved by technology

[0002] In the prior art, there are two main insulation methods for the bottom of the high-voltage power directly into the solid heat storage equipment: one is to use insulating porcelain bottles, and a carbon steel frame is added to the upper part of the insulating porcelain bottles as the load-bearing structure of the heat storage bricks, and the carbon steel structure is temperature-resistant. It is lower than 500°C, so the heat storage performance of the heat storage bricks cannot be fully exerted; the other is to use insulating bricks, but the insulation performance of the insulating bricks cannot meet the requirements, and the leakage current is large when the 10KV voltage is directly input, which has potential safety hazards. 35KV Voltage straight-in is more difficult to solve
[0003] Secondly, thermocouples are mostly used to measure the temperature of the existing high-voltage power directly into the solid heat storage body. Because the charged voltage of the heat storage body is above 10KV, the thermocouple for temperature measurement cannot directly contact the heat storage bricks, and can only measure the temperature of the air in the furnace. It cannot accurately reflect the temperature of the heat storage body itself, and cannot measure the temperature of the heating wire
[0004] Thirdly, the heating wires in the existing solid heat storage equipment are connected in series, and the entire heat storage equipment cannot operate normally after a failure occurs in one place, with high failure rate and poor reliability
[0005] On the other hand, after the solid heat storage equipment is not used for a long time, the heat storage bricks and insulating bricks are easy to be damp, and at this time, the leakage failure of the electrodes is easy to occur
