一、Project completion information

Installation project：High-voltage cable fault and hidden danger monitoring device Installation case

Project time: 2024.05.19

Project completion unit：SHENZHEN DINSEE SMART TECHNOLOGY CO..LTD

二、Functional Features

1、Fault ranging: Fault ranging is the basic purpose of high-voltage cable and hidden danger monitoring device, to realize the positioning of fault section and fault point, and to provide rich recording data for the analysis of the fault;

2、Analysis of fault type: After the fault occurs, the fault type is identified by analyzing the current traveling wave and industrial frequency fault current waveforms of the three phases of A, B and C, which provides a reference for the maintenance of the line;

3、Early warning of hidden faults: Through the monitoring of weak hidden traveling waves of high-voltage cable lines, early warning and overhaul of cables with hidden faults can prevent the occurrence of tripping faults;

4、Equipment self-test:

（a）With the main components of the device to carry out regular self-test function, abnormal conditions need to take the initiative to alarm;

（b）Automatic reset recovery function for possible device crash problems;

5、Acquisition of terminal status information: Realize the acquisition and statistics of terminal solar or CT voltage, battery, temperature, GPS status, GPRS signal strength and other status information;

6、Advanced principle: distributed installation shortens the monitoring distance and solves the problem of signal attenuation. Adopt double-end ranging, can locate the fault point;

7、Powerful signal acquisition unit: the high-voltage cable monitoring device adopts the structure of one host and multiple channels. It can simultaneously collect 7-channel high-frequency signals (3-channel high-frequency current traveling wave, 3-channel hidden current traveling wave, 1-channel voltage traveling wave), 8-channel low-frequency signals (3-channel industrial frequency current, 4-channel ground loop current, 1-channel voltage). Powerful signal acquisition unit for fault recording;

8、Dynamic Wave Speed Adaptation: The system adaptively adjusts the traveling wave speed according to the fault data, which makes the positioning accuracy more accurate;

9、Highly synchronized sampling: Based on GPS timing system and precision sampling synchronization algorithm, the sampling synchronization error of the system is greatly reduced, which improves the ranging accuracy.
