Online monitoring device for conductor temperature

Online Conductor Temperature Monitoring Device

I. Overview

Temperature monitoring of transmission lines has always been a key focus of smart grid monitoring. Since transmission lines operate under high load for a long time, once a line is built, it will generally remain energized until it ages and is retired, barring unforeseen circumstances. When line clamps, hardware fittings, and joints age over time due to factors such as wind and sun exposure, their resistance increases, causing them to operate at high temperatures. Therefore, temperature monitoring of transmission lines is necessary. In some regions of China, where surface vegetation is sparse, transmission lines are directly exposed to sunlight during hot summers, and their temperature may exceed the line's designed carrying temperature in a short time. This not only shortens the service life of line hardware and clamps due to increased temperature, but may also cause problems such as low sag points leading to ground discharge. To address this situation, Telincon has developed the Online Conductor Temperature Monitoring Device.

II. Working Principle

The temperature measuring device at the front end of the Online Conductor Temperature Monitoring Device can measure the temperature of line hardware and clamps. The recorded data is transmitted to the back-end management personnel via wireless 4G signals, and the system can automatically analyze the data. In case of abnormal temperature, it will automatically send an alarm message, which is very convenient for staff to obtain information in a timely manner and rush to the site for inspection.

V. Postscript

The Online Conductor Temperature Monitoring Device enables operation and maintenance personnel to simultaneously monitor the temperature changes of multiple lines in real time remotely, eliminating the need to regularly go to the site to record and monitor the temperature changes of key lines. It has greatly contributed to smart grid monitoring. Its functions of real-time temperature monitoring and timely alarm for abnormal temperatures have been unanimously praised by customers in the industry. It has been put into use in many regions such as Gansu, Hainan, Shaanxi, and Shandong, shouldering the important task of power grid security protection.

VI. Product Advantages

It is recommended to install the Online Conductor Temperature Monitoring Device during power outage, but the device itself supports installation without power outage, and the installation method can be flexibly selected according to on-site conditions. The device adopts contact temperature measurement with small error. Considering that strong current may interfere with the device, its shell and conductor adopt equipotential design, avoiding false alarms.
