Abstract

The invention discloses a disconnection detection implementation method applied to a load management branch device, and the technical scheme comprises the steps: enabling equipment to be capable of distinguishing a disconnection detection instruction and a remote control tripping instruction through the difference of the widths of pulse signals received by a remote signaling port by expanding a DL / T645-2007 protocol; therefore, on the basis that the on-site stock station area does not have the condition of control loop disconnection detection hardware, the disconnection detection function is achieved in the mode that software is matched with existing hardware, and meanwhile the disconnection detection function is achieved by expanding disconnection detection instructions and remote control tripping instruction enabling commands. It is stipulated that the load management branch apparatus must only respond to the relevant signal within the enable command valid time period. According to the invention, the problem that the on-site stock area does not have a broken line detection function is solved, the tripping success rate is improved, the error tripping rate is reduced, the reliability of load management work of the transformation area is greatly improved, and meanwhile, by expanding remote signaling and remote control event records, the reliability of the load management work is improved. And abundant field orderly power utilization management data is provided for theoretical analysis of load management work.
