| Abstract: | Increasing the voltage level of high-voltage electric heating storage device can effectively improve its wind energy absorption capacity. In order to improve the heat resistance and insulation level of wall bushing for high-voltage electric heating storage device, a wall bushing design for electric heating storage device at the voltage of 66 kV and the furnace temperature of 800 ℃ was taken as example, and design methods for key technologies, e.g. high temperature insulation, external heat insulation and heat blocking rings, were investigated. According to the electrical and thermal insulation modes of wall bushing, the design calculation method for wall bushing of electric heating storage device was analyzed. Loading test results of heat and pressure show that the as-proposed design method of wall bushing with high temperature resistance is rational, and has guiding significance to the improvement of voltage level of electric heating storage device. |
