Product Model: TLKS-PLGD

I. Product Description:

With the continuous advancement of smart grid technology, the demand for intelligent power operation and maintenance has become increasingly urgent. In the operation and management of power systems, the safety of high-voltage cable sheaths is the key to ensuring the stable operation of the system. Traditional cable sheath monitoring methods have problems such as inaccurate data and delayed response, which seriously restrict the operation and maintenance efficiency and safety management level of power companies. To address this challenge, our company has independently developed the Cable Sheath Grounding Circulating Current Monitoring Device.

II. Working Principle:

The Cable Sheath Grounding Circulating Current Monitoring Device is an intelligent device designed specifically for the safety monitoring of high-voltage cable sheaths. This system integrates multiple functions such as online monitoring, automatic alarm, cable anti-theft, system self-diagnosis, remote data viewing, and information recording and analysis, realizing all-round, real-time and precise monitoring of the circulating current of high-voltage cable sheaths. With high-precision sensors and advanced intelligent analysis technology, it can quickly and accurately identify abnormal situations, providing strong guarantees for the safety and stability of the cable system.

III. Product Functions:

1. Online Monitoring: Real-time monitoring of the grounding current waveform, amplitude, etc. of the metal sheath of high-voltage cable lines, reducing the workload of inspection personnel and enabling high-precision detection;

2. Automatic Alarm: Automatically triggers the alarm function when the transient increase or sudden decrease of the grounding current is zero;

3. Cable Anti-theft Monitoring: Automatically alarms and notifies the location of the stolen grounding wire after the grounding wire is stolen;

4. System Self-diagnosis: Real-time detection of the system's own faults and uploads the results to the monitoring platform;

5. Remote Viewing: Sends real-time monitoring data to the handheld devices of maintenance personnel via 2G/3G/4G network;

6. Information Recording and Analysis: Records measurement data, fault records and other related parameters, providing intuitive charts such as curve graphs and bar graphs, and statistical reports (weekly, monthly, quarterly, semi-annual, annual);

7. Solar-powered, supports CT power taking, meeting the power supply needs of complex on-site environments.
