Intelligent cable sheath circulation online monitoring system

Intelligent cable sheath circulation online monitoring systemSystem Overview

The DLHL100 cable sheath circulation monitoring system consists of sheath circulation sensors, sheath circulation collectors, etc. It is suitable for online monitoring of sheath circulation in transmission and distribution power cables of 6.6kV and above. It can monitor the abnormal grounding current of high-voltage cable lines in real time and reduce the risk of theft of cable lines such as cross interconnection lines, grounding wires, cross interconnection boxes, and grounding boxes. Support remote viewing function, send real-time monitoring data to maintenance personnel on handheld devices. This greatly reduces the workload of cable operation and maintenance personnel, enabling real-time monitoring of abnormal current detection points and achieving the goal of preventing sudden accidents.

It can achieve accurate measurement and scheduled inspection measurement of grounding circulation, replacing the traditional manual method of regular grounding circulation inspection, effectively determining whether the grounding box has been stolen or the grounding wire has been cut. Greatly reduce the labor intensity of on-site measurement and improve the efficiency of system maintenance.

Intelligent cable sheath circulation online monitoring systemSystem functions

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

2. Automatic alarm: When the transient increase or sudden decrease of grounding current reaches zero, the alarm function is automatically triggered;

3. Cable anti-theft monitoring: After the grounding wire is stolen, the system automatically alarms and informs the location of the stolen grounding wire;

4. System self diagnosis: Real time detection of system faults and uploading the results to the monitoring platform;

5. Remote viewing: Real time monitoring data can be sent to maintenance personnel's handheld devices through 2G/3G/4G networks;

6. Information recording analysis: Record measurement data, fault records, and other related parameters, provide intuitive charts such as curve graphs and bar charts, and statistical reports (weekly, monthly, quarterly, semi annual, annual).

7. Powered by solar energy, supporting CT power supply to meet the power supply needs of complex sites.
