Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a fireproof integrated power distribution cabinet. Background Art

[0002] The distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. It is the terminal equipment of the distribution system. The distribution cabinet is a general term for the motor control center. A large number of connectors and various electronic components are installed inside the distribution cabinet, and there are also a large number of wires. The total resistance value of the distribution cabinet is very high. When conducting, it will dissipate a lot of heat, which will increase the temperature of the distribution cabinet. The distribution cabinet is often compact in structure, small and closed in space. The heat dissipation effect of the existing distribution cabinet cannot achieve the ideal effect. Especially during the peak period of electricity consumption, the distribution cabinet cannot dissipate heat in time, which will cause damage to the components inside the distribution cabinet, and even cause fire and other accidents. In addition, when a fire occurs, the distribution cabinet needs to be isolated and blocked to prevent the fire from spreading.

[0003] The existing technology has the following problems:

[0004] After extensive searching, it was found that Chinese Patent No.: CN213717317U discloses a fireproof high-voltage integrated distribution cabinet, including a distribution cabinet shell, a storage box is fixedly arranged on the top of the distribution cabinet shell, a controller is fixedly arranged on the top of the storage box, a spray device is fixedly arranged on the top of the inner cavity of the distribution cabinet shell, the left and right side walls of the inner cavity of the distribution cabinet shell are respectively equipped with a temperature sensor and a smoke sensor, the left and right sides of the distribution cabinet shell are provided with hollow grooves, a plurality of cooling water pipes are fixedly arranged in the hollow grooves, the bottom of the cooling water pipes is fixedly connected with a connecting water pipe, a fixed shell is fixedly arranged at the bottom of the distribution cabinet shell, a water pump is fixedly installed at the center of the inner cavity of the fixed shell, a plurality of cooling fins are fixedly installed on the outer wall of the connecting water pipe of the inner cavity of the fixed shell, and through holes are opened on the left and right side walls of the fixed shell. The utility model improves the heat dissipation and fire resistance of the device.

[0005] However, the above patent still has some problems in actual use. The most obvious one is that when a fire occurs, oxygen will enter the distribution cabinet through the vents on the distribution cabinet. The oxygen entering the distribution cabinet will come into contact with the combustible materials in the distribution cabinet, causing the combustion reaction to continue, which brings certain difficulties to fire extinguishing.

[0006] To this end, we have proposed a fire-proof integrated distribution cabinet to solve the above-mentioned drawbacks. Utility Model Content
