The invention relates to a moisture-proof high-temperature prevention electric power cabinet. The moisture-proof high-temperature prevention electric power cabinet comprises a drawer component, a drawer push-and-pull device, a position control device, a warning device, a monitoring device, a moisture-proof high-temperature prevention device and a shell. By improving the components and improving the connection manner and coordination manner among the components, the moisture-proof high-temperature prevention electric power cabinet is portable and detachable. The effects of burglary prevention, rust prevention and the like are realized by improving the material of the shell, so that the integral durability and practicability of the electric power cabinet are guaranteed. A moisture-proof device is arranged to be matched with the position control device, so that a moisture-proof effect under relatively low cost is realized.
