Description

Technical Field

[0001] The utility model relates to the field of distribution boxes, in particular to a self-extinguishing distribution box. Background Art

[0002] After years of operation, the distribution box will inevitably age severely, which will increase the probability of short circuit or overload, and thus increase the risk of fire in the distribution box, bringing huge and uncontrollable risks to the distribution box, power system and staff.

[0003] By comparing patent number CN211017954U, an automatic fire extinguishing distribution box is provided, including a distribution box body, one side outer wall of the distribution box body is provided with heat dissipation ports distributed at equal distances, and one side outer wall of the distribution box body is provided with a heat dissipation fan, one side inner wall of the distribution box body is provided with a dustproof mechanism, and the top outer wall of the distribution box body is provided with a solar mechanism, one side inner wall of the distribution box body is provided with a smoke sensor, and the inner wall of the distribution box body is fixed with the same partition, the bottom inner wall of the distribution box body and the top outer wall of the partition are provided with a fire extinguishing mechanism, and one side outer wall of the distribution box body is provided with a box door. The utility model is provided with a heat dissipation port and a heat dissipation fan, and the heat dissipation fan and the heat dissipation port are combined to greatly reduce the temperature of the distribution box body, and effectively prevent the distribution box from catching fire due to excessive temperature.
