AC low-voltage switch cabinet with great dynamic and thermal stability

The invention discloses an AC low-voltage switch cabinet with great dynamic and thermal stability, and belongs to the technical field of low-voltage switch equipment. The AC low-voltage switch cabinet comprises a cabinet bottom, a cabinet body and a cabinet top which are connected in turn. The left side of the bottom part of the internal cavity of the cabinet bottom is provided with a cooling machine. The top part of the cooling machine is provided with a condensation tube. The external wall of the condensation tube and the cooling machine is externally provided with a gas and liquid filtering cover in a sleeving way. The top part of the left side of the internal cavity of the cabinet body is provided with a temperature sensor. The left and right sides of the surface of the cabinet body are provided with air exhausters. The cooling machine and the condensation tube are arranged on the cabinet bottom, and the air exhausters and the temperature sensor are arranged on the cabinet body. In the operation process of the low-voltage AC switch cabinet, the temperature sensor senses internal temperature when temperature reaches tripping temperature, and the cooling machine arranged on the cabinet bottom and the air exhausters arranged on the cabinet body are started through a controller so that tripping caused by excessively high internal temperature can be effectively avoided.
