The cable identification instrument consists of a signal generator, a receiving identification clip and an indicator. When using the Receive Identification Clamp Signal Detector, the signal detected on the other cable lines is much smaller and in the opposite direction. It is easy to determine the amplitude and direction by indicating the meter. The cable identification instrument consists of a signal generator, a receiving identification clip and an indicator.
When using the Receive Identification Clamp Signal Detector, the signal detected on the other cable lines is much smaller and in the opposite direction. It is easy to determine which cable to test with the meter indicating magnitude and direction. In the installation, relocation, maintenance and troubleshooting of power cables, it is used to identify a specific cable in a cable bundle.
The cable identification instrument consists of three parts: a signal generator, a receiving clamp signal detector and an indicator meter. The signal generator mainly generates a special pulse modulation signal, which is added to the stopped cable under test through the output line. The cable under test, when the receiving clamp detector detects a special signal applied to the cable, the power meter pointer of the signal detector swings synchronously with the frequency of the applied signal, while the signals detected on other cables are much smaller and in the opposite direction. The meter indicates the magnitude and direction, making it easy to determine the cable under test. When the receiving clamp signal detector is used in combination with the signal generator, it can be used for judging the live state of the cable, or assisting in finding the short-circuit position of the cable. When the receiver clamp signal detector is used, the cable should be clamped by the clamp jaw.
The live cable identifier is used to identify a specific cable to be found in a bundle of cables in the erection, migration, maintenance and troubleshooting of power cables; it has the characteristics of accurate cable identification, rapid operation, simple operation and wide application range. It is an indispensable testing instrument in cable construction and maintenance. The live/non-live cable identification instrument uses single-chip microcomputer technology at the transmitting end to encode and power the transmitted signal, and drives the large-diameter caliper to couple the signal to the live cable.
The single-chip computer in the receiver decodes and identifies the phase of the received phase-encoded signal. Identify a target cable from a large bundle of other cables based on signal phase characteristics on the target cable. It is a lightweight, compact, lithium battery powered portable instrument.
Suitable for various types of high and low voltage power cables. The cable identification instrument consists of a cable identification transmitter, a cable identification receiver, a transmitting caliper, a receiving caliper and an output signal connecting line. It has high-power current pulse output; on-site signal reception has clear characteristics, light and flexible, high sensitivity, and can effectively suppress on-site power frequency interference; accurate and fast judgment; reliable protection circuit, not afraid of output short circuit; large jaw ф125 is suitable for various cross-sectional areas There is a high-power isolation transformer inside, and the operator does not have any direct electrical contact with the mains.
Greatly guaranteed personal safety. When the live cable is identified, it is not necessary to disconnect the connection between the two ends of each cable and the transformation and distribution equipment. Online identification can be carried out when the cable is live, which improves the efficiency of identification and greatly reduces the direct and indirect damage caused by power outages. economic losses. The above sharing of the relevant characteristics of the cable identification instrument, I hope it can be helpful to all friends.
