They are used in the power plants and transformer substations widely. According to the heat emission of the forced air-cooling enclosed buses, the temperature control system is fixed. Then the equations of the heat balance are built on the heat emission feature of the forced air-cooling enclosed buses. And the equations are solved by applying related procedures. The temperature rise law of the forced air-cooling enclosed buses is found out. The fuzzy controller is designed on the applications of fuzzy control theory, and the temperature rise law of the enclosed buses is simulated. So the effect of control gets better. This design which is an exploratory work of the forced air-cooling enclosed buses provides some useful help for the actual work. 目录
