Cable recognizers can accurately find features cables in a bundle cable, which is a commonly used equipment. Its application range, not only in terms of cable fault processing, but also in cable erasure or migration. The cable recognition has two cable recognizers that can be accurately identified in a bundle cable, which is a commonly used equipment.

Its application range, not only in terms of cable fault processing, but also in cable erasure or migration. There are two types of cable recognizers, one is a charged cable identifier, and the other is not charged. So what is the difference? Let's take a look together.

How to find a specific cable in a bundle cable? How to accurately tell cable? Many power maintenance companies are the most commonly used in power cables, migration, maintenance, and fault handling. The charging cable recognizers, but in the face of complex cable, the environment is different, and it has become a big difficulty in identifying the running cable. . So what is the difference between the charpersible cable identifier and the non-charged cable identifier? How to distinguish it quickly? 1. The main working principle of the cable recognizer works with the main working principle of the transmitting card, the phase encoding signal of the emission card, receives the microcontroller in the caliper, and after the received signals, after filtering, after filtering, Phase identification, when the reception calipers are in the current direction card cable, the identified cable current table is displayed, and the sound light indication is accompanied. The other cable current direction is opposite to the current direction of the recognized cable, and the current table pointer is left.

The working principle of no electric cable recognizers is mainly required to add a special signal to be identified, which is to be received by a dedicated receiver. In the cable that periodically unipolar voltage pulse feed feeds, the direction of the pulse current in the fed cable can be used as an obvious identification standard, and the current flowing is only passed from this cable. 2, the basic parameters of the cable recognizer will emit the red and black two wiring plugs of the emission caliper A, and the emission caliper A card is identified on the recognized cable.

The arrows on the transmit card pliers A points to the cable terminal. On the identified cable other than the emitter two meters, the receiving calipers B are attached to the cable, and the arrows on their caliper must point to the cable terminal. Then check the direction of current and test connection.

In the identification point, each cable is identified with the receiving calipers B. At the time of identification, be sure to always point the arrow on the receiving calipers to the terminal direction of the cable, and tape by cable. On the recognized cable, the receiver current table head pointer must be deflected to the right, and the sound alarm prompt 3, the cable recognizer uses precautions (1) If the cable has a voltage, no load, there is no current flowing on the cable. At this time, the magnetic field was not detected, and it was considered to be a cable, which is very easy to generate misjudgment.

(2) If the cable is not running, this cable will have induction current generation if there is parallel with other running cables, and the induction current will also have a magnetic field. At this time, the instrument will also indicate that I will generate miscrosis. (3) If there is a plurality of cables in the cable ditch, these cables generate magnetic fields. At this time, there will be a magnetic field generated by 50 Hz current throughout the area. At this time, there will be magnetic fields throughout the area, so that the discrimination cannot be done. It is easy to generate miscrosis.

The difference between the charging cable identifier and the non-charged recognition instrument is basically the above, have you learned? I hope I can bring a certain help to my friends need! .
