The invention discloses an intelligent power distribution high-low voltage switch cabinet, which comprises a cabinet body, wherein the interior of the cabinet body is divided into an upper area, a middle area and a lower area, the upper area is provided with a jacking mechanism, the jacking mechanism is used for jacking the top plate of the cabinet body to generate a gap between the top plate andthe side plate of the cabinet body, the middle area is provided with a detection mechanism, the detection mechanism is at least used for detecting the humidity and temperature in the cabinet body, andthe lower area is provided with electrical apparatus elements. According to the invention, the jacking mechanism is used for jacking the top plate of the cabinet body, so that the top plate of the cabinet body is separated from the side plate of the cabinet body, a gap is formed between the top plate and the side plate, and air can enter the cabinet body through the gap for conventional heat dissipation or emergency temporary heat dissipation; and partition arrangement is adopted, and different mechanisms are arranged in the upper area, the middle area and the lower area respectively, so thatmutual interference is avoided, and heat dissipation can be accelerated to a certain extent.
