I. Project completion information
Installation project: distributed fault location monitoring device for transmission lines Installation case
Project time: 2024.11.13
Project completion unit: Shenzhen Dinsee Smart Technology Co.Ltd
II. Distributed fault location device parameters
(1) Basic configuration for fault location monitoring: main control unit, fault location monitoring unit, communication unit, inductive power extraction unit, solar power supply unit, mounting bracket and auxiliary materials.
(2) Detecting and measuring fault distance: online accurate detection and recording of line single-phase ground fault distance, phase-to-phase short-circuit fault distance, disconnection fault distance, and the distance of instantaneous fault occurrence;
(3) High-precision fault localization: it can accurately determine the fault interval of transmission lines, and the reliability of interval localization is >99%;
(4) Error not more than 300 meters: can accurately determine the location of transmission line faults, positioning error 300 meters
(5) Fault cause identification function: can identify lightning strike faults and non-lightning strike faults, lightning strike and non-lightning strike fault identification accuracy >95%;
(6) Recognition of high accuracy: can identify the faults around the strike and counter-strike faults, lightning strike faults nature identification accuracy >90
(7) Dual RAM recording technology: Dual RAM recording technology is adopted to eliminate the "recording dead zone" of transient signals and to prevent leakage of fault data caused by lightning current interference;
(8) On-line recording of line lightning current, localization of lightning strikes and statistics on the number of lightning strikes;
(9) Online detection of line load current, including timed return and recall of load current data;
(10) Software with automatic fault identification, output alarm and data file storage;
(11) 4G/5G wireless transmission: 4G/5G network encrypted transmission, measurement;
(12) Support for remote upgrade: support for remote setting parameters and program upgrade function
As distributed systems are more and more widely used in various industries, the importance of distributed fault localization is becoming more and more prominent. By adopting appropriate methods and technologies, we Shenzhen Dinsee Smart Technology Co.Ltd can better solve the fault problems faced by distributed systems and guarantee the stable operation of the system.
