Cable Identifier

 XHSB505B

This cable identifier is based on the on-site identification of multiple cables urgently needed by high-voltage cable construction, installation and maintenance personnel, referring to foreign advanced technology, and under the guidance of electromagnetic field theory, it is developed by using modern electronic technology and tooling technology.
A very difficult question is often encountered in field operations such as power cable laying, migration, maintenance, troubleshooting: which cable are we looking for? Especially in many cable channels with the same specification, the construction workers are at a loss what to do. This device can help you solve this problem quickly and accurately.
 

 Working principle
Non-charged cable detection: The transmitter mainly generates a special pulse signal, which is added to the cable to be identified through the connecting line. According to the principle of electromagnetic induction, an induction signal consistent with the law of the transmitted signal must be generated along the cable. It is used in the test site. The high-sensitivity receiving clamp plus the handheld receiver detects all the cables on site, and the cable to which the signal is added can be accurately found out according to the indication of the handheld receiver meter (that is, the uncharged cable to be identified).Live cable detection: The transmitter mainly generates a special pulse signal, which is added to a point of the live cable to be identified through a special transmitting clamp. According to the principle of electromagnetic induction, an induction signal consistent with the law of the transmitted signal must be generated along the cable. During the test Use highly sensitive receiving pliers and a handheld receiver to detect all the cables on the site, and you can accurately find out the cable with the added signal (that is, the live cable to be identified) according to the instructions of the handheld receiver.

Technical Parameters
 

Instructions for identification of non-charged cables - direct connection method
 

1. Disconnect the armor at both ends of the cable from the ground, clamp the red clip of the output wire of the transmitter on the core wire of the cable to be tested (good phase or phase with higher insulation), and clamp the black clip of the output wire of the transmitter on the core wire of the cable to be tested. On the ground point or ground stake, the corresponding core wire of the cable is connected to the ground point or ground stake at the far end, as shown in the figure above.

2. Turn on the power switch of the main body of the transmitter, select the "Ⅰ" position of the gear switch, the power switch light flashes three times, and the pointer of the ammeter also swings three times at the same frequency, and the pulse signal is output cyclically in turn.

3. Connect the receiver to the receiving clamp, and the receiving clamp is clamped on the cable to be tested.

4. Note that the direction of the arrow of the receiving clamp is the direction of current inflow (positive direction), otherwise the swing of the watch hand is just the opposite.

5. Turn the receiver adjustment knob clockwise, and when you hear a "beep", turn on the receiver switch. Then adjust the receiving signal strength of the receiver to an appropriate position. At this time, only the signal can be received on the cable that adds the signal, and the signal swing frequency is consistent with the transmitter frequency, and a "di-di-di" sound is issued.

Live Cable Identification Instructions - Coupling Method
 

Coupling method notes:
1. No need to do any operation on the cable under test, just clamp the launch clamp on the cable for testing.

2. Both ends of the cable sheath must be well grounded, otherwise the coupling current will decrease with the increase of the grounding resistance.

3. If the sheath at both ends is not grounded or the middle of the sheath is disconnected, the coupling method cannot be used.

4. When the launching pliers are inserted into the cable, the direction of the arrow on the pliers points to the end of the cable.

5. Keep the receiving clamp and transmitting clamp at a distance of 2 meters as much as possible.

Method:
1). Connect the output end of the transmitter to the launch clamp, and clamp the launch clamp to the proper position of the live cable to be identified, as shown in the figure above.

2). Turn on the power switch of the main unit of the transmitter and select the "II" position switch. The power switch light flashes three times, and the pointer of the ammeter also swings three times at the same frequency, and the pulse signal is output cyclically in turn.

3). Connect the receiver to the receiving clamp, and the receiving clamp is clamped on the cable to be tested.

4). Note that the direction of the arrow of the receiving clamp is the direction of current inflow (positive direction), otherwise the hands of the watch will swing in the opposite direction.

5). Turn the receiver adjustment knob clockwise, and when you hear a "beep", turn on the receiver switch. Then adjust the receiving signal strength of the receiver to a suitable position. At this time, only the signal can be received on the cable that adds the signal, and the signal swing frequency is consistent with the output switching frequency of the transmitter, and the sound of "di-di-di" will be issued.

XHSB505DS

I .Description

XHSB505DS live cable identification instrument, also known as cable identification instrument, multi-function cable identification instrument, and intelligent cable identification instrument, is designed for power cable engineers and cable workers to solve the technical problems of cable identification. The user can accurately identify one of the target cables from the multiple cables through the instrument, so as to avoid accidentally sawing the live cables and causing serious accidents. The cable identification starts from the operation at both ends of the cable. The double numbering at both ends of the cable must be ensured to be accurate. This instrument is designed with PSK technology combined with precise algorithms. No matter how reliable the memory of on-site staff is, it cannot replace the recognition of professional instruments. This product also has the functions of live cable identification, power failure cable identification, AC current test, and AC voltage test. It is composed of a transmitter, a transmitting current clamp, a receiver, and a receiving flexible current clamp.

Transmitter: It transmits signals to the target cable during the identification of live cables and power-off cables. Built-in high-performance rechargeable lithium battery, automatic impedance matching, and automatic protection. The transmitter adopts an integrated special toolbox design, uses polypropylene plastic as raw material, and adds new composite fillers for one-time injection molding. It has low density, strength, rigidity, hardness, wear resistance, heat resistance, and insulation performance. The cabinet can withstand a pressure of about 200kg, the host's large LCD displays the remaining battery power in real time, white backlight, and dynamic indication of the emission signal, which is clear at a glance.

Transmitting clamp: When the live cable is identified, the transmitting clamp couples the signal from the transmitter to the target cable. The jaw size is Φ120mm. The transmitting clamp has directivity. The transmitting signal flows in from the direction indicated by the arrow on the transmitting clamp.

During live identification: use calipers to couple output pulse currents, emit four frequencies: 625Hz, 1562Hz, 2500Hz, 10kHz, couple to the target cable (target cable is a three-core armored cable) through the transmitter, and inject composite pulses into the cable core Current signal, the pulse current generates an electromagnetic field around the target cable for the receiver and flexible current clamp to detect and identify; because the pulse current is directional, the detection is also directional.

When power failure identification: Directly connected output pulse current is used to inject pulse encoding current signal into the cable core. This current generates an electromagnetic field around the target cable for the receiver and flexible current clamp to detect, decode, and identify; because the current has directivity, so detection is also directional.

Receiver: It is a handheld device, 3.5-inch color LCD screen, built-in high-speed microprocessor, combined with precise algorithms, to identify and decode the pulse code current signal of the transmitter, and has a signal strength calibration function to display signal strength and detection results. Exquisite and intuitive; dynamic display of color scale bars, clear at a glance, successful cable identification check mark, non-target cable check mark, can quickly and automatically identify the target cable. At the same time, the testable voltage range is AC 0.00V~600V (50Hz/60Hz), the measurable AC current range is AC 0.00A~5000A (50Hz/60Hz), and the measurable current frequency is 45Hz~70Hz.

Flexible current clamp: It is a Rockwell coil with excellent transient tracking ability, can quickly identify the pulse code current generated by the transmitter, and is suitable for thick cables or irregularly shaped conductors. The inner diameter of the jaw is about 200mm, and it can clamp cables below Φ200mm, without disconnecting the tested circuit, non-contact measurement, safe and fast.

Special note: This cable identification instrument has both live cable identification and power failure cable identification functions. When power failure cable identification, it is strictly forbidden to connect to the live cable. Live cable identification is only applicable to three-core armored cables. When identifying, the transmitting clamp and receiving clamp cannot be mixed, and the direction of the input signal must be consistent.
