The distribution system consists of distribution substations, high-voltage distribution lines, distribution transformers, low-voltage distribution lines and corresponding control and protection equipment. The distribution control switch will have a higher load when working, resulting in heating. If it heats up for a long time, the distribution control switch itself may catch fire, which will eventually lead to danger.

The dry powder fire extinguishing agent bottle is assembled in the storage box, the connecting pipe is installed on the rear end face of the dry powder fire extinguishing agent bottle, and the rear end of the connecting pipe is equipped with a solenoid valve, the right end of the spraying pipe is equipped with a solenoid valve, and the left end of the spraying pipe extends into the box body. This design increases the auxiliary fire extinguishing function of the utility model. The silicone balloon is assembled in the through hole by glue, and the upper end of the silicone balloon is in contact with the travel switch. The travel switch is installed on the rear end face of the equipment box, and the battery is arranged in the equipment box. This design realizes the purpose of automatic opening. The utility model has a fire extinguishing function, realizes trigger opening, has good stability and high reliability.

[0004] However, the above design still has some shortcomings. During the fire extinguishing process, the dry powder used for fire extinguishing may penetrate into the interior of the equipment, causing the equipment to be corroded and worn, affecting the long-term performance of the equipment. Therefore, we propose a distribution switch with protective function to solve the above problem. Utility Model Content

The bottom end of each mounting screw passes through the mounting plate and is threadedly connected to the outer surface of the fixing pad.

[0009] A controller is installed on the outer surface of the box body, a plurality of ventilation holes are provided on the outer surface of the box body, a box door is installed on the outer surface of the box body, and a sealing gasket is installed on the outer surface of the box door.

[0010] Wherein, two fixing plates are fixed on the outer surface of the box body, and the outer surface of each fixing plate is threadedly connected with two fixing screws.

[0011] Among them, the sealing assembly includes an installation groove opened inside the box body, a partition is fixed on the inner wall of the installation groove, two threaded rods are rotatably connected between the outer surface of the partition and the inner wall of the installation groove, and the outer surfaces of the two threaded rods are threadedly connected with a sealing plate.

[0012] Among them, two motors are fixed on the outer surface of the partition, and the output end of each of the motors passes through the partition and is drivingly connected to the rear end of the threaded rod.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model drives the filter frame to extract the air inside the box body by arranging a vacuum pump, and quickly extinguishes the fire by isolating the oxygen. By extracting air instead of using the traditional fire extinguishing medium (such as water, dry powder, gas, etc.), the physical and chemical damage to the distribution switch and the electrical equipment can be reduced. By arranging a smoke sensor, it is helpful to monitor the fire situation in real time so as to respond quickly, and the fire situation can be controlled quickly to reduce the loss caused by the fire. By arranging the filter frame, in the process of extracting air, the filter frame can capture particulate matter in the smoke, prevent these particles from entering the vacuum pump, and thus protect the vacuum pump from damage.
