TLKS-PLGDThe high-voltage cable circulation current online monitoring system, with core advantages such as high-precision real-time monitoring, multi-scenario adaptive power supply, intelligent early warning and anti-theft, and remote visual operation and maintenance, has become the preferred device for intelligent operation and maintenance of high-voltage cables. Traditional cable sheath circulation current detection mostly relies on regular manual inspection, which has drawbacks such as data lag, large errors, inability to capture transient anomalies in real time, and high labor costs, making it difficult to predict hidden issues such as cable insulation aging, grounding faults, and ground wire theft in advance. However, this device realizes 24-hour uninterrupted online monitoring, can accurately capture subtle fluctuations in circulation current, automatically trigger anomaly warnings, and is equipped with dual power supply of solar energy and CT, as well as wireless remote transmission function, adapting to complex scenarios such as cable trenches, tunnels, and outdoor manholes. It completely makes up for the shortcomings of traditional manual operation and maintenance, effectively improves the safety and stability of high-voltage cable operation, and is deeply favored by the power industry. Its core value is mainly reflected in the following aspects:

Working Principle

TLKS-PLGDHigh-Voltage Cable Circulation Current Online Monitoring System captures core operation data such as the waveform and amplitude of the grounding current of the metal sheath of high-voltage cables in real time through the front-end acquisition unit, and dynamically monitors the circulation current change status around the clock. The device processes, screens and integrates the original collected data in real time, and synchronously uploads it to the background monitoring platform and the handheld devices of operation and maintenance personnel through the 4G wireless communication network. The system has an built-in intelligent judgment mechanism, which can accurately identify abnormal working conditions such as transient rise and sudden drop of circulation current, and also monitor the on-off status of the grounding wire. Once a fault, anomaly or ground wire theft is determined, it will automatically trigger an alarm and upload the fault location information immediately. In addition, the device has self-diagnosis capability, can check its own operation faults in real time, and is equipped with data storage and analysis functions to achieve early warning before cable faults, traceable faults, and controllable status.

Core Functions

1. All-weather online monitoring: Collect the waveform and amplitude data of the grounding current of the metal sheath of high-voltage cables in real time, dynamically grasp the operation status of the cables, and eliminate monitoring blind spots.

2. Intelligent anomaly alarm: Automatically trigger early warnings for abnormal working conditions such as transient rise and sudden decrease of grounding current, and timely feedback circulation current faults.

3. Ground wire anti-theft monitoring: Has the function of identifying grounding wire theft, can accurately determine the theft status and locate the fault location, and effectively prevent the grounding system of cables from being stolen and damaged.

4. Device self-diagnosis: Monitor the operation status of the device itself in real time, automatically check for device faults and upload them to the platform, ensuring the stable and reliable operation of the monitoring system.

5. Remote data viewing: Relying on 2G/3G/4G wireless networks, push real-time monitoring data to the handheld devices of operation and maintenance personnel, realizing anytime, anywhere remote operation and maintenance viewing.

6. Data recording and analysis: Automatically retain parameters such as daily monitoring data and fault records, providing data support for cable status analysis, tracing, and operation and maintenance optimization.

7. Dual-mode adaptive power supply: Supports two modes of solar lithium battery power supply and CT power taking, adapting to complex on-site working conditions such as outdoor areas, tunnels, and no external power supply.
