The invention discloses an intelligent dehumidification system of electrical equipment. The intelligent dehumidification system comprises an intelligent control unit and an environment control unit, wherein the intelligent control unit comprises a master control unit and a system power supply unit; the environment control unit comprises a dehumidification unit, an atomization unit, a forced circulation unit and a monitoring unit. According to the system, the environment can be simultaneously monitored, LED (Light Emitting Diode) digital display can be realized, and the temperature and the humidity can also be correspondingly set and displayed respectively. The intelligent control unit can be used for automatically controlling the environment control unit according to site conditions. Moisture discharged by the equipment is forcibly evaporated by using the atomization unit and is safely discharged. The system is a piece of preferred environment monitoring equipment for guaranteeing high-efficiency and safe operation of an intelligent power grid.
