Introduction: The SY-200 cable identifier is used to identify a specific cable in a bundle of cables during power cable erection, migration, maintenance, and fault handling. It has the ability to identify the cable accurately (qualitative and quantitative double discrimination), fast, and operate. Simple, wide range of applications. It is of great significance in cable construction and maintenance work. The live/unpowered cable identification instrument uses a single-chip technology to encode and power the transmitted signal at the transmitting end, and drives the large-diameter caliper to couple the signal to the live cable. The microcontroller in the receiver decodes and phase identifies the received phase encoded signal. The target cable is identified from a large bundle of other cables based on the uniqueness of the signal phase characteristics on the target cable. It is a small, compact, portable instrument. Suitable for all types of high and low voltage power cables. Features: This instrument not only recognizes live cables, but also recognizes that there are no cables. The system consists of a signal transmitter, a receiver, a transmitting caliper and a receiving caliper and a number of connecting wires. It has high-power current pulse output; the spot receiving signal features clear, light and flexible, high sensitivity, can effectively suppress the field power frequency interference; can identify the cable to be identified when the cable under test is charged and not charged. Accurate and fast judgment; reliable protection circuit, not afraid of output short circuit; large jaw ф150 is suitable for power cables of various cross-sectional areas; internal high-power isolation transformer, the operator does not have any direct electrical contact with the mains. working principle The transmitter and receiver of the live cable identification instrument adopts single-chip coding and decoding technology and PSK technology widely used in the field of communication. A phase-encoded signal with an average value of 0 is transmitted on the transmitting caliper, and the single-chip receiver in the receiver filters the received signal through hardware and software, and then performs phase identification. Point the arrow that emits the caliper and the receiving caliper to the cable end. When the receiver caliper clamps a cable, the receiver ammeter is right-biased with an audible and visual indication. While clamping the other cables, the ammeter is left-biased, and the current direction is opposite to the current direction of the identified cable, and there is no sound and light indication. This embodies the uniqueness of the identified target cable. It is easy to distinguish the identified cable from multiple cables. Moreover, since the signal current intensity on the identified cable is the same, the receiving calipers receive the same electromagnetic signal strength along the cable, and the identified cable is not limited by the length of the identified cable.
