When an electrical switch in an electrical cabinet is in short circuit and is on fire, a fire extinguishing isolation system and a detection alarm system start to work, when the electrical switch is in short circuit and is on fire, dense smoke is generated, meanwhile, because the electrical cabinet is a closed space, the dense smoke generated by combustion can be detected by a smoke sensor 201 in a short time and gives an alarm through an alarm lamp 202, meanwhile, buzzing is given out for reminding, then, a first motor 116 of the fire extinguishing isolation system in the equipment is started, an output shaft of the first motor 116 drives a second belt pulley 117 to rotate, the second belt pulley 117 drives a first belt pulley 115 to rotate through a belt, further, the first belt pulley 115 drives a hollow winding shaft 113 to rotate, an isolation roller shutter 114 is put down, the isolation roller shutter 114 is changed into a state from a state shown in fig. 10, at the moment, an isolation part 114a in the state shown in fig. 11 does not bulge, in the process that the isolation roller shutter 114 is put down, the isolation roller shutter 114 stably moves down due to the pulling of a guide rod 1111 at the bottom, when the isolation roller shutter 114 moves down, the first counterweight roller shutter 114 stops working, and the isolation roller shutter 116 is separated from the isolation frame 1114 before each electrical cabinet.
Then the third motor 1212 is started, the output shaft thereof drives the second transmission gear 1213 to rotate, and since the second transmission gear 1213 is meshed with the racks on the opposite sides of the two pin pulling sliders 1214, the second transmission gear 1213 drives the two pin pulling sliders 1214 to slide back and forth to pull out the safety pins of the two transverse fire extinguishers 1218, in this process, the left pin pulling slider 1214 moves upwards, the right pin pulling slider 1214 moves downwards, and the pin pulling slider 1214 slides on the guide block 1215;
then the second motor 123 is started, the driving gear connected with the output shaft of the second motor drives the meshed first transmission gear 124 to rotate, and then the first transmission gear 124 drives the transmission screw rod 122 to rotate, because the threads at the two ends of the transmission screw rod 122 are symmetrical and opposite to each other, so that the two pushing pieces 126 screwed on the two ends of the transmission screw rod 122 can move oppositely, when the two pushing pieces 126 move oppositely, the two telescopic rods 1217 extend to drive the two transverse fire extinguishers 1218 to move oppositely, and because the extrusion handles of the transverse fire extinguishers 1218 are positioned in the fixed guide grooves 1210a and the first mounting seat 1210 is not moved, the extrusion handles can be extruded, so as to start the transverse fire extinguishers 1218, release the carbon dioxide gas in the transverse fire extinguishers, inject the carbon dioxide gas into the hollow isolation roller shutters 114 through the ventilation pipes 129, support the isolation parts 114a on the isolation roller shutters 114 like blowing balls, as shown in fig. 10, and further isolate the front parts of the separation areas of the isolation frames 1114;
after the isolation part 114a of the isolation roller blind 114 is supported, the metal mesh 118, the fire extinguishing material bag 119 and the plastic film 1110 connected with the isolation roller blind are pushed into the isolation frame 1114, when the electrical switch catches fire, the plastic film 1110 on the fire extinguishing material bag 119 is burned and melted by the temperature of the area, and after the plastic film 1110 is melted, holes exist on the rear surface of the fire extinguishing material bag 119, so that dry powder in the fire extinguishing material bag 119 is diffused out, and the electrical switch on fire is extinguished;
further, when the electrical switch that catches fire is more serious, the surface fabric of the side in front of the fire extinguishing materials bag 119 can also melt together, at this moment, the carbon dioxide gas in the isolation roller shutter 114 passes through the metal mesh 118, and wrap up the rest fire extinguishing dry powder that is holding the fire extinguishing materials bag 119 and puff on the corresponding electrical switch, put out flame, a large amount of carbon dioxide that blows out simultaneously still can be with dispersing earlier in the dry powder of partition region and raise, make it cover on the electrical switch, so realize only putting out a fire the work to the electrical switch that catches fire, utilize dry powder and carbon dioxide gas to put out a fire the operation, carbon dioxide can drive away the oxygen in the region that the electrical switch is located, the dry powder can cover on the electrical switch, and the electrical switch that does not catch fire can not be covered by the dry powder.
