The invention discloses an intelligent control system of a high-tension transformation network. The system comprises a master control CPU, a power supply module, a data transmission module, an active control module, a sampling module, an acousto-optic alarm and a wireless communication module; the sampling module collects current signals in a power transmission line and transmits the current signals to the master control CPU; the master control CPU is connected with the power supply module, the data transmission module, the active control module, the acousto-optic alarm and the wireless communication module; and the master control CPU is also connected with multiple relay control modules. According to the intelligent control system, a wireless emission module is in communication connection with a wireless receiving intelligent controller module, the communicating stability and accuracy of the system are high, standby power consumption of electric appliances can be reduced, and electric energy is saved effectively. The system uses a UPS for power supply to prevent system damage caused by sudden power off, the precision of current detection is high, use is convenient, and control is precise.
