Electric power cable of cable identifying instrument set up, migration, maintenance and fault processing used to judge a bunch to find a particular cable in the cable; Distinguishing cable, accurate, fast, simple, widely used and so on. It is indispensable to the construction and maintenance of the cable test instruments.

Main features

The instrument consists of cable identifying transmitters, cable identification receiver fired calipers and receives output signal connections lines and calipers. It has a high power pulse output; Site characteristics of the received signal is clear, light and flexible, high sensitivity, can suppress the frequency interference; Accurate, rapid; Protection circuit and reliable, does not fear the output short circuit; Big JAWS ф 150 for a variety of sectional area of power cable; With high power isolation transformers, operator and there is no electric mains on direct contact. Greatly to ensure the security of the person. Charged cable identification without disconnecting the cable ends of transformer substation equipment and connections, in a cable in a charged state online recognition, improves the efficiency of identification greatly reduced due to power outages caused by the direct and indirect economic losses.

The greatest feature of this instrument is:

1, the combined function of charged and neutral and the recognition, not only for the outage identification and judgment of the cable, but also suitable for classification and identification of charged cable, operation is very simple, very easy to use.

2, the cable identification instrument is different from regular identifier, using the latest communications technology, at the transmitter using one-chip microcomputer technology to encode a signal, power-driven, coupled to the signal cable; Single chip receiver receives phase-coded signal decoding and phase identification. Depending on the target signal phase characteristics and uniqueness of cables cable from a bunch of cable identifying the target. Reliable performance, long cables can do accurate identification is a small light, compact, portable instrument. Suitable for all types of low voltage power cable.

Working principle

YD charged cable identification instrument transmitter and receiver based on single-chip encoding, decoding and PSK technology is widely used in the communication field. Launch launch calipers is 0 phase-coded signals, single chip receiver receives signals through hardware and software filter, phase identification. Fired calipers and caliper receives the arrow point to the cable terminal, when the caliper grabbing a cable of the receiver, receiver current meter on the right side, accompanied with a sound and light indication. While grabbing the other cables, ammeter left, current direction and identify cables in opposite directions, no sound and light indication. This reflects the recognition of the uniqueness of the target cable. Are easy to identify in the cable from the cable clear discrimination. And is recognized on the cable the signal strength of the current line is the same, receiving calipers in the received signal strength along the cable line, identification of cables without recognized cable length restrictions.
