When the bus duct body 1 is rapidly heated, cooling water continuously passes through the first connecting groove 303 to cool down the bus duct body 1 and reduce the damage to the bus duct body 1 caused by the rapid temperature rise of the bus duct body 1.

[0025] A plate box 307 is installed on the top of the fixed box 305 above, and the plate box 307 is connected to the fixed box 305. A baffle 308 is movably installed inside the plate box 307.

[0026] Working principle: When working, first install the protection frame 301 on the outside of the bus duct body 1, connect the two connecting pipes 306 to the cooling water tank, and then the baffle 308 will close the end of the connecting pipe 306 for water inlet;

[0027] Since the protection frame 301 is equidistantly sleeved on the outside of the bus duct body 1, when the temperature of the bus duct body 1 rises sharply, the bus duct body 1 may expand due to heat, and the protection frame 301 is arranged on the outside of the bus duct body 1, which can generate inward pressure on the bus duct body 1, thereby reducing the deformation of the bus duct body 1 due to thermal expansion;

[0028] When the bus duct body 1 experiences a rapid temperature rise, heat is transferred to the expansion gas filling space in the transverse tube 315 through the second heat conducting rod 319 and the first heat conducting rod 318, so that the expansion gas in the expansion gas filling space expands due to the heat, pushing the movable plate 316 to move toward the plate box 307, and pushing the baffle 308 to move upward through the connecting rod 314 and completely enter the plate box 307, so that the connecting pipe 306 is opened. At this time, the cooling water in the cooling water tank continuously flows from the connecting pipe 306 and the fixed box 305 through the first connecting groove 303 under the action of the circulating pump, so as to cool down the bus duct body 1, improve the protection of the bus duct body 1, and reduce the damage to the bus duct body 1 caused by the rapid temperature rise of the bus duct body 1.
