The invention discloses a detection system for a low-voltage transmission line. The system includes: a detection device with a storage module, which is arranged on the transmission line, and the detection device is used to store the station area number and phase sequence code in the received broadcast data packet into the storage module; the main control device, which is arranged on the transformer The secondary side is used to send broadcast data packets to the detection devices installed on the power lines of each phase when receiving the meter reading instruction; the handheld meter reading machine is used to send the meter reading instruction from the detection device after sending the meter reading instruction through the wireless network. The station area number and phase sequence code are read in the device. The invention solves the technical problem in the related art that the station zone and phase sequence to which the power transmission line belongs cannot be accurately determined.
Description
technical field [0001] The invention relates to the field of power transmission, in particular to a detection system for low-voltage transmission lines. Background technique [0002] With the rapid development of power network, higher requirements are put forward for the safety of power network and power consumption. As far as transmission lines are concerned, their safe operation and safe maintenance have become an important part of power safety. Transmission lines The main cause of failure is the deterioration and failure of insulation performance, while leakage or short circuit is the main reason for the deterioration of insulation performance of transmission lines. When a leakage or short circuit fault occurs on the transmission line, the fault point can be determined by the single-phase electric energy meter of each node on the transmission line. However, after the fault point is determined by the single-phase electric energy meter, the fault line cannot be determined. ...
