Temperature Monitoring Of Power Transmission

- Jul 01, 2020-

With the development of society, there are more and more kinds of supplies that depend on electricity, and the installation of power systems is inconvenient to maintain due to long-term power supply. At the same time, due to cable aging, environmental corrosion, loosening of tightening bolts, etc., the cable joints or power equipment become hot Cause safety hazards and seriously threaten the safety of people's lives and property. How to detect abnormalities early in the occurrence of dangers and avoid the occurrence of dangers has become the primary consideration of modern power managers. Due to the electrical characteristics of the power industry, common active temperature monitoring equipment often fails to achieve results or even causes more problems. The development of passive temperature monitoring systems has become the best way to monitor the current deadlock.

The fire caused by the heat of electricity and IT equipment room is shocking

The implementation method of temperature monitoring system based on RFID ultra-high frequency passive chip technology is: adding a temperature sensor to the ultra-high frequency RFID chip, customizing the electronic tags suitable for various environments and pasting it to high-voltage substations in power transmission and low-voltage power distribution The key nodes of the facility are easy to heat the surface of the component, or embedded in the conductor joint, using the RFID UHF reader with Android system to read the temperature data in the electronic tag in real time and analyze it, and set it according to the actual temperature value that needs to be monitored The warning line, when the temperature is higher or lower than the warning line, sound and light alarm, take pictures, and transmit the information to the cloud system to remind the power maintenance personnel to follow up.

Features of the scheme: 1. The use of passive RFID UHF electronic tags has little impact on the monitoring target and good consistency; 2. The stability of temperature measurement is good. The temperature sensor chip and the RFID chip are combined into one, which prevents the back road. The performance deviation in the package; 3. There is a digital ID, each temperature monitoring label has its own EPCID, which guarantees the uniqueness among many nodes; 4. Strong anti-interference, the electronic label is specially packaged and is subject to on-site interference Small damage, and wireless transmission, has strong anti-interference ability; 5. Easy installation and debugging, the power temperature monitoring label is developed for the industry, small and durable, easy to install and debug; 6, wide temperature measurement range, strong applicability, different packages The temperature monitoring label can adapt to the use environment of -40~250℃.
