Smart cable identification by use cable identification system
In electric power construction, the unique identification of cables is a very strict job because it involves facilities and personal safety.
The intelligent recognition of flexible calipers is a method with the clearest results and the strongest anti-interference ability.
1. The choice of signal transmission method
lThe transmitter must be set to 1280Hz or 640Hz frequency. Generally, the default 1280Hz is used when starting up; 1280Hz can meet most of the test requirements, and 640Hz can be used for ultra-long cables.
lFor non-operating cables, use the direct connection method, and the core wire-earth connection method is preferred; if it is not convenient to connect, use the phase wire-sheath connection method, and it is not recommended to use the sheath-earth connection method.
lThe caliper coupling method is preferred for running cables.
Three, interface introduction
In the power-on state, the receiver automatically recognizes the connected accessories and sets it to the caliper receiving mode,
The receiver works at 1280Hz by default when it is turned on, and the frequency is set to be consistent with the transmitter; in the caliper mode, the current value is directly displayed, and compared with the calibrated current to calculate and display its percentage; the phase dial displays the current phase; the recognition result displays the correct recognition icon √ or error icon ×.
Four, calibration
The intelligent identification of the flexible caliper requires the receiver to first measure the current intensity and phase of the target cable at a known position as a benchmark for comparison. The measurement result at an unknown point is compared with the benchmark to make a judgment on whether the identification is correct or incorrect. The process of measuring and recording the reference current and phase is the calibration.
Perform calibration at a location close to the transmitter and ensure that it will not be interfered by it. For the caliper coupled transmitting signal, it should be at least 2m away from the transmitting caliper. Clamp the target cable with the receiving clamp.
Note that the direction arrow of the caliper must point to the end of the cable.
All subsequent identification measurements are based on this. After the calibration is completed, the data will not be lost when shutting down.
When identifying another cable, it must be re-calibrated for the new target cable.
Five, identification
Leave the calibration point and reach the position that needs to be identified, and clamp the cable with the flexible clamp.
Note that the direction arrow of the flexible caliper keeps pointing towards the end of the cable.
