The invention discloses an intelligent distribution transformer, solving the problem that the current transformer state information cannot be transmitted. The intelligent distribution transformer is characterized in that: the box cover of the distribution transformer 1 is provided with an on-load capacity regulation and voltage regulation tap switch 2 and an intelligent liquid level temperature sensor 3; the on-load capacity regulation and voltage regulation tap switch is connected to a device for online monitoring current and voltage of the distribution transformer consisting of a power distribution box, a full optical fiber current mutual inductor, an optical voltage mutual inductor and a combined unit. The intelligent distribution transformer precisely measures current and voltage on the secondary side of the power distribution transformer, returns the feedback to the on-load capacity regulation and voltage regulation tap switch, enables the on-load capacity regulation and voltage regulation tap switch to perform switching between the big capacity and the small capacity according to the change in the load and determines that whether the operation state of the transformer is faulted according to the temperature and the liquid level signal, promptly gives the feedback to the industrial control system and realizes the intelligent regulation of voltage and capacity.
