The method of charging cable identification device Technical Analysis

March 15, 2023

GH-6601B cable identification device is charged multiple cables factory site to identify problems that need to be resolved in accordance with the construction of high voltage cable installation and maintenance staff, with reference to foreign advanced technology, under the guidance of electromagnetic theory, the use of modern electronic technology and tooling technology developed It made. The cable electrification identifier is mainly used for the accurate identification of multiple cables in the field to overcome the major power outage accidents or personal safety accidents caused by the sawing faulty cables frequently occurring at the construction site, greatly improving the efficiency of construction and maintenance, and ensuring industrial and agricultural production and people's lives. Work properly. The cable electrification identifier converts the 220VAC power input from the grid into an identification of the high-power special signal required by the electronic technology. This signal is added to any good phase (or a phase with a relatively high resistance) at the beginning (or terminal) of the cable to be identified. According to the principle of electromagnetic induction, the cable along the line will inevitably sense the signal with the same regularity as the transmitted signal. At the excavation site, all the cables in the field are clamped with a highly sensitive detector, and the added signal can be accurately found according to the detector indication. cable.

Precautions:

1. The cable charging identification device should be judged mainly by the orientation, and the amplitude is the auxiliary judgment method.

2. The red socket of the main unit output of the identification instrument should be connected to the phase of the cable to be identified or the phase with relatively high insulation value, and the terminal of the cable to be identified must also be connected to the ground reliably.

3. When wiring, be careful to form a return flow with the earth.

4. The direct connection method reflow resistance is not more than 1kΩ, and the coupling method loop resistance is not more than 200Ω.
