Accuracy and Real-time Monitoring Effect of Transmission Line Sag Measurement and Early Warning Terminal

Alternative product names: Transmission Line Sag Measurement and Early Warning Terminal, High-Voltage Line Sag Online Monitoring Equipment, Conductor Sag Monitoring and Early Warning Device, Transmission Line Conductor Sag Online Monitoring Device.

Application Background

In recent years, the national energy authorities have issued multiple documents requiring real-time monitoring of key operating statuses of transmission lines such as conductor sag and temperature. Relevant data shows that line faults caused by abnormal sag account for a relatively high proportion of total faults, especially during the summer peak load period and winter icing season, where the risk is more prominent. Therefore, realizing online and precise sag monitoring has become an important direction for refined management of transmission lines.

1.Product Positioning

TLKS-PMG-HC Transmission Line Sag Measurement and Early Warning Terminal is an intelligent device used for real-time monitoring of conductor sag and ground clearance. By continuously collecting key data and conducting automatic analysis, this device provides real-time status feedback for operation and maintenance personnel, assisting in preventing line faults that may be caused by abnormal sag, supporting the safe and stable operation of the power grid, strictly complying with the "General Technical Specifications for Transmission Line Status Monitoring Devices" of State Grid Corporation of China and China Southern Power Grid, and has a large number of online engineering application cases.

2.Working Method

TLKS-PMG-HC Transmission Line Sag Measurement and Early Warning Terminal is based on a high-precision sag sensor to measure the vertical distance between the conductor and the ground in real time. Combined with parameters such as the horizontal inclination angle of the conductor, it calculates the sag value through a built-in algorithm. When the monitored data exceeds the set threshold, the system can send early warning information to the specified platform through multiple communication methods, facilitating timely response by operation and maintenance personnel.

3.Main Functions

1.High-precision Status Monitoring: Adopts a dedicated sag sensor to collect real-time data such as conductor ground clearance and horizontal inclination angle, ensuring the accuracy of sag calculation results.

2.Intelligent Collection and Transmission: Supports automatic data collection at preset intervals (default is 30 minutes), and can respond to remote commands to realize flexible reporting and efficient transmission of data.

3.Multi-level Early Warning Mechanism: Once abnormal sag is identified, the system immediately initiates multi-channel alarms and pushes early warning information through multiple methods such as platforms and SMS.

4.Intelligent Power Management: Built-in battery voltage monitoring function ensures long-term stable operation of the device in field environments and effectively extends the service life of the device.

5.Secure Data Interaction: Uses data encryption transmission technology to ensure communication security, and can seamlessly connect to the main station platforms of provincial power companies, promoting data sharing and business collaboration.
