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 clamps, 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 in hot summer, and their temperature may exceed the line's designed carrying temperature in a short time. This not only shortens the service life of line fittings and clamps due to the temperature rise, but also may cause the problem of discharge to the ground due to excessively low sag points. 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 fittings and clamps. The recorded data is transmitted to the background administrator via wireless 4G signal for viewing. The system can automatically analyze the data and send an alarm message when an abnormal temperature is detected, which facilitates staff to obtain the information in a timely manner and rush to the site for inspection, making it very convenient.

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 visit the site to record and monitor the temperature changes of key lines. It has greatly contributed to the intelligent monitoring of the power grid. Its functions of real-time temperature monitoring and timely alarm for abnormal temperatures have been widely 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 the conductor adopt equipotential design, avoiding false alarms.
