When the circuit is normal after self-inspection, the circuit controller can control the switch reset device on a single circuit breaker to start, push the circuit breaker switch on to power on, thereby ensuring the normal operation of the circuit and reducing manual operation of the staff. The line card slot can then be used to connect and store the line to prevent the line from crossing, etc. Three groups of line protection structures composed of a remote current sensing controller, a circuit breaker, a line card slot and a transformer controller are arranged horizontally on the insulating fixing plate to protect three different groups of lines, thereby increasing the practicality of the device.

When the detection chamber 732 detects the gas and confirms the fire, the circuit controller 24 controls the internal power of the device to be cut off, and then controls the start-up of the driving gas cylinder 702 and the solenoid valve 2 706 and other fire extinguishing structures to extinguish the fire; S5. When the driving gas cylinder 702 is started, the external electrical components are powered by the battery 13, and then the two sets of electric push rods 714 provided inside the box body 2 are controlled by the control panel 10 to release the limit on the fixed block 715, so that the fixed block 715 falls and the box body 2 is sealed. At the same time, the alarm light 11 and the alarm horn 12 sound an alarm and light, and then a signal is sent through the signal transmitter 15.

[0032] The working principle of the device is as follows: first, when the device is used, the box door 3 is opened manually, and then the wires are manually connected to a line protection structure composed of a remote current sensing controller 20, a circuit breaker 21, a line card slot 22 and a transformer controller 23, and then the baffle 8 provided at the rear end of the outer shell 701 is manually removed, and then the pressure gauge 703 provided on the top of the driving gas cylinder 702 and the control panel 10 provided on the outside of the box 2 are used to check whether the internal pressure of the driving gas cylinder 702 and the four groups of carbon dioxide storage tanks 705 is sufficient. If it is not sufficient, it needs to be supplemented manually, and then the circuit controller 24 controls the internal circuit to be energized, and then the current is regulated by the remote current sensing controller 20. The circuit breaker 21 is used to automatically cut off the power supply when the line is overloaded, and the electromechanical overload protection is performed. When the line is normal after the circuit self-test, the circuit controller 24 can control the switch reset device 28 on the single circuit breaker 21 to start, and the circuit breaker 21 is pushed on to energize, thereby ensuring the normal operation of the circuit and reducing the manual operation of the staff. The line card slot 22 can be used to card and store the line to prevent the line from crossing, etc. Then, the three groups of line protection structures composed of the remote current sensing controller 20, the circuit breaker 21, the line card slot 22 and the transformer controller 23 are horizontally arranged on the insulating fixing plate 27, and three groups of different lines can be protected. The fire detector 70 provided inside the box 2 The bottom hole 8 sucks the gas inside the box 2 into the gas pipe 730, and then the sampling fan 731 connected to the gas pipe 730 provides suction to transport the gas to the detection chamber 732 for detection, and then the gas is filtered by the filter 733 to prevent the fire gas from flowing out, thereby triggering other devices, and then the filtered gas is discharged through the exhaust port 734. When the detection chamber 732 detects the gas and confirms the fire, the solenoid valve 1 704 is started to make the driving gas cylinder 702 enter the four groups of carbon dioxide storage tanks 705 through the pipeline to drive the carbon dioxide material, and then the carbon dioxide is diverted by the solenoid valve 2 706 to supply the diverter valve 709 and the fixed-point fire extinguishing shell 718 respectively, and then the diverter valve 70 The two groups of nozzles 710 provided on the outer side of the 9 spray carbon dioxide fire extinguishing agent to extinguish the fire inside the box body 2. At the same time, the motor 726 provided inside the fixed-point fire extinguishing shell 718 drives the transmission rod 727 to rotate, and then the transmission rod 727 drives the gear 724 to move in the tooth groove 725 inside the fixed-point fire extinguishing shell 718, and then the tooth groove 725 drives the connecting rod 723 and the movable shaft 722 to transmit, and then the movable rod 721 is driven to rotate as a whole through the movable shaft 722. When the gear 724 rotates to a certain angle, the motor 726 stops rotating, so that the movable rod 721 is paused, and then the movable block 720 is pushed as a whole through the electric push rod 729 provided on the other side of the movable rod 721, and is inserted into the slot 719 for fixing.Then, the carbon dioxide fire extinguishing agent is sprayed out through the nozzle 710 provided on the movable block 720 to carry out the fixed-point fire extinguishing. After a certain amount of carbon dioxide fire extinguishing agent is sprayed out, the electric push rod 2 729 drives the movable block 720 to retract as a whole, and then the motor 726 starts to drive the movable block 720 as a whole to the next card slot 719 for fixed-point fire extinguishing. While the driving gas cylinder 702 is started, the two sets of electric push rods 1 714 provided inside the box body 2 are controlled by the control panel 10 to release the limit of the fixed block 715, so that the fixed block 715 falls, and the box body 2 is sealed to prevent air from assisting combustion. When the fixed block 715 falls, the alarm light 11 and the alarm horn 12 are automatically controlled by the control panel 10 to start, reminding the staff that a fire has occurred. The device can be powered from the outside through the battery 13. When the internal power supply is cut off, the electrical components can be operated. Through the cooperation of the data transmitter 14 and the signal transmitter 15, a signal can be sent when a fire occurs inside the device. This is the working principle of the device.
