Self-cleaning electric power cabinet

The invention discloses a self-cleaning electric power cabinet which comprises a box body, a working cavity is formed in the box body, two electric transducers which are symmetrical up and down are fixedly arranged in the working cavity, detection boxes are clamped on the left side wall and the right side wall of the working cavity, and cooling plates which are transversely and uniformly distributed are arranged on the upper sides of the electric transducers. The left side wall and the right side wall of the working cavity are each provided with an air outlet box capable of sliding up and down, the air outlet boxes are slidably connected with the two-way threaded rod, cooling is conducted through the flow guide plate without using external air, cooling is conducted through self-circulation air and cooling water in the working cavity, and the cooling efficiency is improved; the amount of dust mistakenly running into the detection pipe from the absorption cavity is prevented, so that the working stability of th
