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.
