The invention discloses an electricity-stealing prevention system used for a residential quarter. The electricity-stealing prevention system comprises an industrial control computer, a wire inlet side electric power wire, an integrated type electric meter box, a wire outlet side electric power wire and a monitoring chip module, wherein the industrial control computer is connected with two current detectors through data wires for detecting the current values of the wire inlet side electric power wire and the wire outlet side electric power wire of the integrated type electric meter box respectively, and making comparison to find a difference value between the two wires so as to judge the current loss quantity entirely; the integrated type electric meter box is provided with the monitoring chip module and electric meters; each electric meter is connected with the monitoring chip module through the corresponding data wire; the monitoring chip module transmits the monitored data to the industrial control computer through a signal transmitting and receiving device; and the industrial control computer enables the integrated type electric meter box to give out an alarm or to perform power failure so as to reduce electric energy loss. The electricity-stealing prevention system is precise in structure and accurate and specific in detection, can well prevent electricity stealing behaviors in the residential quarter and has quite high practical value.
