1. Introduction

In modern power networks, transmission lines are large in scale and operate outdoors for long periods. As grid loads continue to increase, clamps and wires are highly prone to abnormal temperature due to the Joule heating effect of current. Faults caused by overheating of lines result in hundreds of millions of dollars in losses annually, and may also lead to regional power outages, causing serious impacts on production and daily life. Traditional manual inspection is inefficient and struggles to capture temperature changes and potential issues in a timely manner. Therefore, the high-precision, intelligent TLKS-PMG-TP intelligent temperature monitoring sensor for key nodes of transmission lines has become an urgent need to ensure the safe operation of power grids.

2. Product Overview

The TLKS-PMG-TP intelligent temperature monitoring sensor for key nodes of transmission lines launched by Telcom is the "smart sentinel" guarding the safe operation of transmission lines. Adopting advanced online monitoring technology, this device performs real-time, precise monitoring and collection of the temperature of line clamps and wires, and can sensitively capture subtle temperature changes. Once an abnormal temperature is detected, it will immediately issue an overheating early warning, helping operation and maintenance personnel grasp the line status in a timely manner and take proactive measures to eliminate problems, thus building a solid barrier for the safe and stable operation of the power grid.

3. Operation Mechanism

The TLKS-PMG-TP intelligent temperature monitoring sensor for key nodes of transmission lines collects temperature signals of clamps and their joints in real time by arranging high-precision temperature sensors at key nodes of transmission lines. These sensors act as "body temperature monitors" for the lines, sending the collected temperature data to the data acquisition terminal via wireless transmission. After analyzing and processing the data, the terminal transmits the information to the monitoring center in real time through a communication network. Operation and maintenance personnel at the monitoring center can intuitively view the temperature data and change trends of each monitoring point through a visual platform, achieving all-round, dynamic monitoring and intelligent early warning of the temperature status of transmission lines.

4. Core Function Analysis

6. Engineering Cases

The 220KV high-voltage transmission line under the jurisdiction of North China Power Company undertakes the power supply task for surrounding industrial parks and residential areas. In the past, during summer peak power consumption, line tripping and power outages often occurred due to failure to detect abnormal clamp temperatures in time, resulting in economic losses and inconvenience to daily life.

After installing the TLKS-PMG-TP intelligent temperature monitoring sensor for key nodes of transmission lines, the system real-time captured that the temperature of a certain clamp rose from 38℃ to 72℃. When it reached the 70℃ early warning threshold, an alarm was triggered immediately, and the data was synchronized to the monitoring center. Based on this, operation and maintenance personnel quickly located the problem of poor contact of the clamp and dealt with it in a timely manner, successfully avoiding a tripping accident. Since then, temperature abnormal faults on this line have been significantly reduced, and power supply stability has been greatly improved.
