The invention belongs to the field of high-voltage electric energy metering equipment, and specifically discloses an intelligent control device for a multi-ratio current transformer, including: a parameter module, a central processing module, a storage module, an input module, a display module, a current adjustment multiple module, and a current switching transformer. Compared with the module, it also includes a power module that provides working power for the intelligent control device. The central processing module is connected to each module, the secondary current of the multi-ratio current transformer is connected to the parameter module, the current adjustment multiple module, and the input terminal of the current switching ratio module, and the current adjustment multiple module, current switching transformer The output terminal of the ratio module is connected to the current input terminal of the metering ammeter. The present invention can output normal electrical signals to supply energy meters for metering when the current transformer is no-load, light-loaded or overloaded, so as to ensure the accuracy of the metering results, and further prevent the current transformer from burning out related metering equipment due to poor overload capacity. caused by power outages.
