Distributed Intelligent Fault Diagnosis Device for Transmission Lines

I. Product Description:

Transmission lines are a crucial component of power systems, and their operating status directly affects the safety and stability of the entire power grid. However, due to factors such as long line lengths, complex environments, and external interference, transmission lines are often at risk of faults. Traditional accident investigation methods mainly rely on manual patrols, which not only consume a large amount of manpower and material resources but also have low efficiency. Therefore, our company's Transmission Line Fault Diagnosis System came into being.

II. Working Principle:

Distributed Intelligent Fault Diagnosis Device for Transmission Lines innovatively integrates advanced induction power acquisition technology, realizing continuous autonomous operation without an external power supply. This breakthrough significantly reduces the installation complexity and later maintenance costs of the system. The system has high-precision data acquisition capabilities and can accurately capture the power frequency fault current and fault traveling wave current waveform data on the line. These data are like the "fingerprints" of the line's health status, providing a solid data foundation for accurately judging the line's operating status and fault location. The collected key data is transmitted to the background data center in real time through an efficient and stable 4G network channel, ensuring the timeliness and accuracy of data transmission and creating conditions for remote monitoring and analysis. Operation and maintenance personnel can easily access the data center through Internet, observe real-time dynamic change charts and data analysis of key parameters such as line current, intelligently identify potential abnormalities in the line, and achieve comprehensive monitoring of the line's health status. Once the system detects any fault signs, it will immediately activate the emergency response mechanism, automatically generate a detailed fault report, and accurately mark the fault location information, and send it to the operation and maintenance team through the preset channel. This process greatly shortens the time from fault discovery to response, provides operation and maintenance personnel with valuable "golden repair time", effectively improves the efficiency and accuracy of power grid fault handling, and escorts the stable operation of the power system.

III. Product Functions:

1. Determine the fault interval based on the power frequency fault current

2. Implement precise traveling wave location in the determined fault interval

3. For transmission lines with complex network structures, distributed fault diagnosis devices can be installed at branch points to divide the complex network into several simple single-line structures

4. Identify the causes of faults, realizing the identification of lightning-caused faults and non-lightning-caused faults. At the same time, it can also identify lightning strikes on lightning conductors, towers and conductors when lightning strikes do not cause tripping

IV. Technical Parameters:

1. Ambient temperature: - 40℃~ +85℃

2. Ambient relative humidity: 0~ 100%RH

3. Atmospheric pressure: 86kPa ~ 106kPa

4. Storage temperature: - 40℃~ +85℃

5. Wind speed: 0km/h ~ 100km/h

. Line load: The normal working current range for system coupling power acquisition is 20~ 1000A

7. Compatibility: It can withstand strong electric fields and strong magnetic fields of 500kV, and has reliable and stable electromagnetic compatibility capabilities

V. Summary:

Distributed Intelligent Fault Diagnosis Device for Transmission Lines, with its intelligent and networked advanced technology, has built a system for comprehensive monitoring and real-time fault response of transmission line status. The system not only has excellent fault detection and precise location capabilities, but also provides solid data support and technical backup for the safe and stable operation of the power system. With the vigorous development of smart grid construction, this system will undoubtedly play an increasingly critical role in future power networks, promoting grid management towards a more efficient and intelligent direction.
