Product aliases: Overhead Transmission Line Conductor Sag Monitoring Device, Overhead Line Sag Monitoring Device, Power Sag Monitoring System, Conductor Sag Online Monitoring System

1. Industry Trends

In September 2023, the National Energy Administration specifically emphasized in the "Guiding Opinions on Strengthening the Safe Operation and Management of Transmission Lines" that real-time monitoring of key operating statuses such as conductor sag and temperature should be strengthened. Industry data shows that accidents such as line tripping and ground discharge caused by abnormal conductor sag account for a considerable proportion of transmission line faults, and the risk increases significantly especially during summer high loads and winter icing periods. This highlights the urgency of conducting precise and online monitoring of conductor sag status, and intelligent monitoring methods are gradually becoming standard configurations for refined management of transmission lines.

2. Product Overview

TLKS-PMG-HCOverhead Transmission Line Conductor Sag Monitoring Device is a high-precision, intelligent monitoring product developed by Telcom Technology. This device can continuously and automatically collect and analyze key parameters such as the sag and ground distance of transmission line conductors. Through real-time data presentation and intelligent early warning, it helps operation and maintenance personnel accurately grasp the operating status of the line, effectively prevent various safety hazards caused by abnormal sag, and provide reliable technical support for enhancing the active security defense capabilities of the power grid.

3. Working Principle

TLKS-PMG-HCOverhead Transmission Line Conductor Sag Monitoring Device is centered on a high-precision sag sensor. The sensor measures the vertical distance between the conductor and the ground in real time, combines parameters such as the horizontal inclination angle of the conductor at the outlet of the clamp, and calculates the precise sag value through the built-in algorithm model. When the monitoring data exceeds the preset safety threshold, the system will immediately send alarm information and data to the remote monitoring center through communication networks such as 4G/WIFI/fiber optic, guiding operation and maintenance personnel to respond quickly and realizing closed-loop management from status perception to risk disposal.

4. Core Functions

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

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

3. Multi-level Early Warning Mechanism: Once abnormal sag is detected, the system immediately activates 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: Adopts data encryption transmission technology to ensure communication security, and can seamlessly connect to the main station platforms of provincial power companies to promote data sharing and business collaboration.

6. Installation Scheme

TLKS-PMG-HCOverhead Transmission Line Conductor Sag Monitoring Device is flexibly designed and adapts to various installation scenarios to meet different monitoring needs:

1. Jumper Sag Monitoring: Fix the sensor directly on the jumper of the tension tower to accurately monitor its sag changes.

2. Insulator String Tilt Monitoring: Install sensors at the upper and lower ends of the insulator string, and evaluate the sag status by measuring its tilt angle.

3. Span Midpoint Sag Monitoring: Install the monitoring device between the two conductors at the midpoint of the span to directly realize real-time measurement and comparison of phase-to-phase sag.
