Electricity is very important in our lives, which can be converted into a variety of energy. As a tool that carries current, its quality problem is more important. The cable has the characteristics of energization and external insulation.
However, some cables are very important in our lives for a long time, which can be converted into various energy. As a tool that carries current, its quality problem is more important. The cable has the characteristics of energization and external insulation.
However, some cables may fail under long-term use, and to find faults and repair, cable recognizers are essential. Let's take a look at the technical standards of cable recognition. The cable identifier consists of signal generator and reception identification clamp and instruction table three, and the signal detected on the other cables when receiving the clamp signal detector, and the inverse direction is contrary to the direction, and it is very It is easy to determine the measured cable.
Take a look at the cable recognizers technical standards. Detection Routing and Fault Downtown: The wire diameter is less than 0.5 cables 3km, and the other cables can reach 20 km. Defective point of failure insulation resistance: 0-50mΩ.
Positioning test accuracy:≤±10cm 4, detection cable depth:≤3M. Digital cable recognition is based on the high-voltage cable construction installation and maintenance personnel need to solve the problem of foreign cable site recognition, refer to foreign advanced technology, under the guidance of electromagnetic field theory, is developed by modern electronic technology and tooling process technology. Directory Technical Indicators Features Working Principle Panel and Structure Description Precautions.
1. Technical indicator jaws:≥140mm, closed time diameter≥120mm. 2, power: 1kva or closed diameter≥150mm. 3, identification mode: direction, amplitude.
4, weight and shape size: 2kg 320×280×210. 5, function characteristics: Identification accurate; big identification jaws are suitable for various cables; the operation is extremely simple; the instructions are clear and intuitive; the main, the accessories are portable, beautiful, the hand is good; the whole machine is reliable, the output size and reception sensitivity can be Adjust, suitable for a variety of scenes. 6. Working principle: Transform the 220VAC power supplied by the grid through electronic technology to identify the high power special signal, this signal is added to the cable gear (or terminal) either a good phase (or the resistance is relatively high) Depending on the principle of electromagnetic induction, the cable will inevitably induce a sensing signal that is consistent with the regularity of the transmitted signal. All cables are measured on the site with a high-sensitive detector, and can accurately find the signal according to the detector instruction. Cable.
The panel and structural description are for the convenience of on-site, designed as an integrated structure of aluminum alloy box packaging. 7. The panel layout is as follows: Power: Identifier main machine power input socket with fuse holder display: Output Current Digital Display Outbox: When used, the red socket needs to identify the cable line, black socket. Digital cable identifier structural continuous structures use integrated structures, portability is very good.
8. Precautions The original ground lines of the cables to be identified must be all unspeakable. The identifier host output red socket should be connected to a good phase or resistance of the cable to be identified, and the terminal to be identified must also be reliably connected to the ground. The main purpose of the above two points is to make the reflow current must be formed.
About cable recognition instrument technical standards, we will talk about it today, want to know more related knowledge, please continue to pay attention to Xiaobian.
