Application scenarios and specific functions of the instrument
Cable identification is designed for power cable engineers and cable workers to solve the technical problems of cable identification. Live cables and power cut cables can be identified. The user can accurately identify one of the target cables from multiple cables through the instrument to avoid serious accidents caused by wrong sawing of live cables.

During cable identification, 10 cables can be calibrated in advance at the transmitting end and then received at the remote end for identification, which greatly saves the round-trip operation time of engineering personnel and improves work efficiency. Mark √ for successful cable identification and mark √ for non target cable ×, It can quickly and automatically identify the target cable. This function is realized by signal transmitter, receiver, signal transmitting clamp, connecting test line, flexible caliper and stethoscope. The stethoscope can be used when it is not convenient to use the caliper.

The ground resistance test uses the precision 4-wire method to measure the ground resistance on the site, and introduces FFT (fast Fourier transform) technology and AFC (automatic frequency control) technology to automatically identify the interference and select the measurement frequency to minimize the impact of the interference. The maximum rated output current is 6mA, and the measurement range is 0.001 Ω ~ 2000 Ω. The function is realized by the cooperation of the receiver and the connecting test line.

Insulation resistance test is specially used for insulation test in laboratory or on site. It is suitable for measuring the resistance of various insulating materials and the insulation resistance of transformers, motors, cables and electrical equipment. Embedded high-precision micro current measurement system, digital boost system, automatic discharge circuit, etc. The rated output test voltage range is 100V ~ 2500V, and the insulation resistance measurement range is 0.01M Ω ~ 2.50t Ω. The function is realized by the signal transmitter and the connecting test line.

Signal transmitter: used for pipeline path detection, cable identification and insulation resistance test. The equipment can add identification signal to the target cable through direct output, caliper coupling, induction, etc. the signal has 6 different mixed pulse signals such as 640hz, 1280hz and 10kHz for selection. The maximum signal output power is 10W, and the 10 gears can be adjusted. So as to adapt to different application environments and make pipeline detection and cable identification more accurate and reliable. The instrument has built-in large functional rechargeable lithium battery, automatic impedance matching and full-automatic protection. The transmitter is designed with an integrated special toolbox. Its box can withstand a pressure of about 200kg. The host computer has a 5.4-inch color l liquid crystal display, and the real-time dynamic display of signal output and battery usage.

Firing pliers: applicable to clamp coupling method. The transmitting clamp couples the signal sent by the transmitter to the target cable, and the jaw size Φ 125mm, the transmission clamp has directivity, and the transmission signal flows in from the direction indicated by the arrow on the transmission clamp.

Receiver: used for pipeline path detection, cable identification and grounding resistance test. Built in multiple shielded 3D antennas, it can effectively identify 6 different pulse coded current signals generated by the transmitter, such as 640hz, 1280hz and 10kHz. It can also identify 50Hz and 250Hz power frequency signals and RF signals with center frequencies of 33khz and 82khz. The 3.5-inch color LCD screen is used to dynamically display 360 ° all-round pipeline route indication, depth, current and relative position of the pipeline in real time.

Flexible current clamp: used for cable identification. The current clamp is a Rockwell coil, which has excellent transient tracking ability and can quickly identify the pulse coded current generated by the transmitter. It is suitable for thick cables or conductors with irregular shapes. The inner diameter of the jaw is about 200mm, which can be clamped Φ For cables less than 200mm, it is not necessary to disconnect the tested line, and non-contact measurement is safe and fast.

Stethoscope: used for cable identification. Similar to the shape of the mouse, it can quickly sense and identify the current signal in the transmitter or cable. The arc-shaped sensor is designed to fully fit the cable surface. Cooperating with the transmitter and receiver of this product, it can realize most of the functions of the flexible current clamp and can replace the flexible current clamp for cable identification on most occasions. When using, the stethoscope can be placed close to the tested cable, which is extremely suitable for some occasions where it is not easy to use the current clamp to ring the cable for testing.
