The utility model discloses an intelligent control device for a capacity-variable energy-saving preassembled transformer substation. The intelligent control device includes an intelligent detection and control device which is installed in a high-voltage wire entering cabinet of the transformer substation; the intelligent detection and control device includes a load detection unit and an intelligent control unit, wherein the load detection unit transmits acquired and processed load current into the intelligent control unit; and the intelligent control unit controls the switch-on and switch-off of circuit breakers through a circuit breaker control unit. Through application of current detection and conversion and intelligent programmable control technologies, switch-on and switch-off of high-voltage load switches and low-voltage circuit breakers are controlled so that the capacity-variable energy-saving preassembled transformer substation is capable of automatically switching among 33%, 66%, 100% of the capacity
