The invention discloses electric power supply equipment with a fire extinguishing function. The electric power supply equipment with the fire extinguishing function comprises a distribution box, an upper partition plate and a lower partition plate are fixedly installed at positions, close to the top end, in the interior of the distribution box, a storage cavity is formed between the top end of the upper partition plate and the top end in the interior of the distribution box, the interior of the storage cavity is filled with a fire extinguishing material, a mixing chamber is arranged between the bottom end of the upper partition plate and the top end of the lower partition plate, and powder feeding pipes are fixedly connected to the surface of the bottom end of the upper partition plate. According to the electric power supply equipment with the fire extinguishing function, through an installed reaction mechanism, carbon dioxide can carry the fire extinguishing material to penetrate through a through holes in the surface of the lower partition plate to uniformly flow into the distribution box, due to the fact that carbon dioxide is a non-combustible substance, the specific gravity of carbon dioxide is slightly heavier than that of air, the carbon dioxide can be attached to comburent after entering the distribution box, air is blocked, fire is extinguished; moreover, the fire extinguishing material can quickly cover the space in the distribution box, the fire extinguishing range is large, and therefore quick and effective fire extinguishing can be achieved, the spreading of fire disasters is avoided, and the use safety is ensured.
