online temperature monitoring equipment for strain clamps

Tension Clamp Temperature Online Monitoring Device

I. Overview

Transmission lines operate by carrying high current 24 hours a day, and their temperature remains at a stable level. In the past, most old wires had a temperature limit of 70 degrees Celsius (this limit has been raised now). Considering the impact of external environments (such as high temperatures in summer), the line itself can operate normally beyond 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 or even melting may occur. In addition, short circuits caused by aging line fittings can also lead to a sharp rise in line temperature, instantly exceeding the upper limit of its bearing temperature, which will also cause significant economic losses. To enable operation and maintenance personnel to observe the temperature changes of the line in real time, Telcom has developed the Tension Clamp Temperature Online Monitoring Device.

II. Working Principle

The temperature measuring device at the front end of the Tension Clamp Temperature Online Monitoring Device can measure the temperature of line fittings and clamps. The recorded data is transmitted to the background administrator via wireless 4G signals, and the system can automatically analyze the data. If an abnormal temperature is detected, an alarm will be sent automatically, which is convenient for staff to obtain information in a timely manner and go to the site for investigation, making it very convenient.

V. Conclusion

The Tension Clamp Temperature Online Monitoring Device eliminates the need for operation and maintenance personnel to go to the site to measure 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 via wireless network communication, so that staff do not need to regularly check for abnormal temperature data frequently, which is highly efficient. The contact temperature measurement method of the device reduces the probability of false alarms, and it has strong heat resistance, enabling normal operation even in high-temperature environments. The device meets the technical requirements of the State Grid for such products and has been put into use in multiple regions including 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), and the configuration can be adjusted according to the number of lines. All measured data can be centrally transmitted by the same host.
