Abstract
The invention relates to an extremely hot temperature detection device for an electric heating energy-storage furnace. A plurality of groups of ropes or geometric bodies made of chosen appropriate mediums are arranged in a high-temperature region in the electric heating energy-storage furnace, and the end of each medium rope or geometric body is connected with a small hole arranged at the end of a movable support arm of a status indicator. Within a normal temperature range, the movable support arm of the status indicator is pulled by the medium ropes or the geometric bodies to compress a return spring so that the end of the movable support arm departs from a button of an overheat state output travel switch, the overheat state output travel switch is released at the moment, and the electric heating energy-storage furnace works normally. When the furnace temperature of the electric heating energy-storage furnace is overheated, under the effect of high temperature, the medium ropes or the geometric bodies lose structural strength and break, the end of the movable support arm is rotated anticlockwise under the effect of the return spring so that the button of the overheat state output travel switch is pressed, the overheat state output travel switch outputs signals to switch off a working power source of the electric heating energy-storage furnace, and the furnace temperature is prevented from rising continuously.
