The utility model discloses a preventing stealing power metering box for transformer, the first one is a closed CT box, a low pressure insulated casing pipe of a transformer is arranged in the CT box through a big hole under the box; a metering CT is arranged in the internal CT box, electricity is transferred from the transformer to a low-voltage device by a copper bar or a cable through metering CT; the second one is a closed gauge tables box, an electric meter is arranged in the gauge tables box; the metering CT is connected with the electric meter in the gauge tables box through a special cable. Unless the door or sealing lock (magnetic sealing lock) is destroyed, the arrangement and the cable layout inside the box can not be changed, thereby the effect of anti-stealing electric energy is fundamentally achieved, and economy loss of the electrical professional department can be reduced effectively. With a scientific design, reasonable manufacture cost, convenient operation, the utility model is a preventing stealing power device with great popularization value in power industry.
