In the power system, buried cables are an important component of power transmission, and their safe and stable operation is directly related to the normal operation of social production and residents' lives. However, due to the fact that buried cables are usually deeply buried underground, their location, direction, and condition are difficult to intuitively determine, which poses significant challenges for cable maintenance, repair, and construction. Therefore, Cable&Pipe Locator has emerged as a powerful assistant in power maintenance and construction.
1、 Overview of Cable&Pipe Locator
Cable&Pipe Locator is a tool specifically designed for detecting and locating underground cables or pipelines, utilizing the principles of electromagnetic wave reflection and induction, combined with advanced technologies such as digital filtering, wireless reception, and software control. The device mainly consists of a signal transmitter and a receiver. The signal transmitter applies signals through induction, direct transmission, and clamping, while the signal receiver is responsible for receiving and feedback signals, including the position, direction, burial depth, and current measurement of the cable.
2、 Working principle
The working principle of Cable&Pipe Locator is relatively complex, but the core lies in the interaction between electromagnetic waves and underground metal pipelines or cables. When high-frequency electromagnetic waves are radiated to metals, they cause eddy current effects, resulting in changes in the parameters of the radiator (such as impedance, equivalent inductance, etc.). The changes in these parameters are subsequently converted into changes in voltage, current, or tone as output indicators.
Specifically, the signal transmitter transmits signals to underground metal pipelines or cables through three methods: induction, direct transmission, and clamping. Then, the signal receiver receives and processes these signals, and uses complex algorithms to analyze information such as the position, direction, burial depth, and current of the cable. In addition, the detector also has fault location and current measurement functions, providing important technical support for solving power faults and ensuring people's livelihood.
3、 Practical application
Cable&Pipe Locator has a wide range of application scenarios in the power system. Firstly, in terms of cable maintenance, the detector can quickly and accurately locate the position and direction of the cable, helping maintenance personnel to discover and handle potential fault points in a timely manner, improving maintenance efficiency and quality. Secondly, in terms of cable construction, detectors can avoid unnecessary losses caused by blind excavation, ensuring the safety and economy of construction.
Specifically, during cable maintenance, maintenance personnel can locate the exact position of the cable through the indication of the detector and conduct targeted inspections and repairs. At the same time, the detector can also help maintenance personnel understand the burial depth and current situation of the cable, providing important reference for subsequent maintenance and repair work. During the cable construction process, the detector can accurately detect the position and direction of underground pipelines and cables, providing strong support for the formulation of construction plans.
4、 Product features and advantages
There are various types of Cable&Pipe Locators on the market, each with its own unique features. Taking Puqi PQWT-GX900 as an example, this detector has the characteristics of high sensitivity, strong anti-interference ability, and wide measurement range, and can be applied to cable detection needs of different specifications and types. At the same time, the detector is also equipped with an external induction clamp, which improves the flexibility and applicability of detection.
In addition, some high-end Cable&Pipe Locators also have intelligent and networked features, which can achieve remote monitoring and data sharing. These functions make the application of detectors in the power system more convenient and efficient, injecting new vitality into the development of the power industry.
5、 Conclusion
The importance of Cable&Pipe Locator as a reliable assistant in power maintenance and construction is self-evident. With the continuous development of the power industry and advances in technology, the performance and functionality of detectors will also be continuously improved and perfected. In the future, we have reason to believe that Cable&Pipe Locator will play a more important role in the power system, providing strong guarantees for the safe, stable, and efficient operation of the power industry.
