[0031] Working principle:

[0032] Initial state: the box door 2 is closed, and the door lock 3 closes and locks the box door 2 and the box body 1; the first adapter block 28 and the second adapter block 27 are connected and conductive; the reel 21 is locked and cannot rotate by the piston rod 19; the temperature is room temperature, and the alarm 34 is not lit; the first temperature-sensitive glass tube 14 is intact, and the airbag 12 is not inflated; the second temperature-sensitive glass tube 15 is intact, and the carbon dioxide has not overflowed; the temperature bag is normal and has not inflated, and the L-line channel is closed.

[0033] If there is a short circuit or fire at the air switch 4, the scope of the accident is small and the degree is low. First, the resistance of the temperature-sensitive resistor 38 decreases at high temperature, so that the alarm 34 lights up; secondly, the second temperature-sensitive glass tube 15 breaks due to heat, and carbon dioxide overflows and fills the gap between the bottom plate 8 and the rear side wall of the box body 1, and then is sprayed to the circuit interface of the air switch 4 through the pressure valve 50 in the oblique mouth 51 to extinguish the fire; at the same time, the temperature bag 44 in the base 39 connected to each air switch 4 expands due to heat, so that the temperature bag pushes the switch plate 45 downward, the L-shaped channel 54 opens, and the carbon dioxide enters the L-shaped channel 54 through the gas channel 48 to push the third adapter block 41 out, so that the third electric plug 42 of the third adapter block 41 is separated from the upper terminal 43 of the air switch 4, and the air switch 4 is powered off.

[0034] If all the air switches 4 and other power distribution equipment in the distribution box are all protected from electric fire, the scope of the accident is large and the degree is high. At the same time as the power is cut off and the fire is extinguished, the first temperature-sensitive glass tube 14 is also ruptured by heat, so that the vibration sensor 55 receives a signal and transmits it to the inside of the airbag 12. The airbag 12 expands, and the impact force of the expansion successively breaks the second plastic plate 11 and the first plastic plate 10. Then the airbag 12 continues to expand and presses the U-shaped plate 16. The U-shaped plate 16 pushes the hydraulic medium to make the piston plate 18 move upward, so that the airbag 12 expands and presses the U-shaped plate 16. The plug rod 19 disengages from the slot 22 on the reel 21, and after the chain drum is unlocked, the chain 23 is pulled down by the gravity plate 24 to contact the ground for discharge under the action of gravity; then the airbag 12 expands to the inner wall of the top surface of the box body 1, and the airbag presses the second connecting rod 33, so that the second adapter block 27 slides and disengages from the first adapter block to cut off the power. At this point, all equipment in the distribution box is powered off. Finally, the airbag 12 expands to fill the entire box body 1, and the air switch 4 and other distribution equipment in the box body are sealed and extinguished with carbon dioxide.

The third electric plug (42) cooperates with an upper terminal (43) of the air switch (4). The third adapter block (41) is connected to a first electric wire (40) to conduct electricity and conduct electricity to the upper terminal (43) through the third electric plug (42). The upper terminal (43) conducts electricity to the lower terminal (49) through an internal circuit of the air switch (4). The lower terminal (49) is connected to an output wire (35) and outputs electricity. The upper terminal (43) is an existing internal part of the existing air switch (4).

6. A fireproof and electricity-proof distribution cabinet according to claim 5, characterized in that: A vibration sensor (55) is provided on the side of the safety airbag (12) facing the second plastic plate (11) and corresponding to the first temperature-sensitive glass tube (14). A reactant is provided in the safety airbag (12) and generates gas to expand upon receiving a signal from the vibration sensor (55). The material used to make the safety airbag (12) should be an insulating flame-retardant material to facilitate expansion.
