[0020] It can be seen from Figures 1-4 that a combined low-voltage switchgear cabinet includes a cabinet body 1. A horizontal partition 2 is fixedly connected above the interior of the cabinet body 1. An air circulation chamber 25 is arranged at the top of the horizontal partition 2. A vertical partition 3 is fixedly connected to the bottom of the cabinet body 1 below the horizontal partition 2. A partition plate 4 is fixedly connected to one side of the vertical partition 3.
