I. Overview

Huazheng Electric Cable identification is of great significance in cable construction and maintenance. Both for power cable identification instrument on the market at present, also has in view of the electric cable identification instrument, but in the concrete use, at the scene of the actual cable is often placed the overlying each other together, conventional instrument used calipers tend not to lead to identification card, and largely identify receiving part still use pointer to the header to indicate, the scene due to the vibration failure easily. There are existing equipment often require the site to provide 24

0V power, the user is very inconvenient to use.

Based on this, the research and development department of our company developed a live cable identification instrument with flexible coil and LIQUID crystal display by using modern electronic technology, and changed the design of the main machine into the mode of dry battery power supply, which can solve the disadvantages of the above instrument and is of great help to the actual work. It has the following characteristics:

1. The whole set of instruments can use AA battery to work, to completely solve the on-site no power supply and rechargeable battery is not easy to maintain failure. For the transmitting host, it is specially designed for both AC and DC, which can be powered by either battery or 240V power supply.

2. One-box engineering plastic packing, easy to use, more suitable for transportation and field environment.

3. The large diameter flexible coil receiving part is suitable for all kinds of complex cables.

4. The receiver liquid crystal display is designed with micro-power consumption technology, which is especially power-saving and simple and intuitive to judge.

5. Battery voltage indicator function of receiver. Outdoor visual LCD, sunlight, dark environment can be used.

6. Multi-purpose machine, namely can identify live power cable, can also identify power failure cable.

7. For power failure cables, coupling pliers can be used to apply signals without disassembling cables, or the cable end head and end head can be removed, and the special connection wire prepared can be used to directly apply signals for identification.

II. Major Technical Indicators

1. Launch pliers jaw: ≥130mm when closed, internal diameter ≥125mm

Receiving flexible coil: can be drawn into a straight line, can be distorted, closed into a circular inner diameter ≥135mm

2. Receiver power supply: two pieces of AA alkaline battery, continuous working time ≥8h

3. Host power supply: four pieces of AA alkaline battery, continuous working time ≥3h

Or use AC240V power supply

4. Identification method: waveform direction, waveform amplitude, double judgment basis

5. Receiving sensitivity: The resistance of the ground loop is less than 200 ohms

6. Weight and dimension: about 6.5kg, 47cmX38cmX15cm
