Online temperature monitoring equipment for tension clamps

Online Temperature Monitoring Device for Tension Clamp

I. Overview

Transmission lines, as equipment carrying strong current 24 hours a day, maintain a stable temperature. In the past, most old wires had a temperature limit of 70 degrees Celsius (the current temperature limit has been raised). Considering the impact of the external environment (such as in hot summer weather), the line itself can operate normally exceeding the temperature limit for a short time. However, if the line operates in a high-temperature state for too long, problems such as excessive sag and even melting may occur. In addition, short-circuit problems caused by aging of line hardware will also cause the line temperature to rise sharply, instantly exceeding its carrying temperature limit, which will also bring large economic losses. In order to allow maintenance personnel to observe the temperature changes of the line in real time, Telcom has developed the Online Temperature Monitoring Device for Tension Clamp.

II. Working Principle

The temperature measuring device at the front end of the Online Temperature Monitoring Device for Tension Clamp can measure the temperature of line hardware and clamps. The recorded data is transmitted to the background manager via wireless 4G signal, and the system can automatically analyze the data. If an abnormal temperature is encountered, an alarm message will be automatically sent, which is convenient for the staff to obtain the information in time and go to the site for investigation, which is very convenient.

III. Functional Features

Supports access of 24-channel temperature data;

Has the function of collecting image information near the tower;

Has an automatic collection function, which automatically collects the temperature of wires and hardware at set time intervals;

For the online temperature acquisition unit, it has the functions of collecting power supply voltage, working temperature, etc.;

V. Postscript

The Online Temperature Monitoring Device for Tension Clamp eliminates the need for maintenance personnel to go to the site to measure the line temperature, allowing them to remotely monitor the temperature changes of multiple lines in real time at the same time. The device transmits alarm information through wireless network communication, so that the staff do not have to regularly check for abnormal temperature data frequently, which is very efficient. The contact temperature measurement method of the device reduces the probability of false alarms, and it has strong heat resistance, so it can work normally in high-temperature environments. The device meets the technical requirements of the State Grid for such products, and has been put into use in many regions such as Sichuan, Hainan, and Liaoning.

VI. Installation Suggestions

The device can be installed without power outage. Generally, temperature sensors need to be installed at both ends of a section of line (between two iron towers). It can be configured according to the specific number of lines, and the measured data can be centrally sent by the same host.
