Passive Wireless Sensing Technology

Based on RFID technology, rtec creatively developed a passive wireless temperature sensor without power supply or wiring, which is very suitable for application in switch cabinet, ring network cabinet, branch box transformer, station transformer and other high, medium and low voltage power equipment, triggering a technological revolution of smart grid temperature online monitoring system. The system adopts the most advanced passive sensor technology. The sensor can not only be directly installed on the surface of the charged conductor, but also be read stably in the closed space; With the help of cloud platform, mobile app and local software, the system can realize accurate, real-time and online monitoring of temperature measurement points, timely warning of temperature rise over the line, and recording, statistics and graphical analysis of historical temperature data. The operation and maintenance personnel can not only check the temperature data of the temperature measuring point anytime and anywhere through the system, but also receive the temperature rise alarm in time; It can also make use of the statistical report and curve graph of historical temperature data to analyze and study the long-term operation status of the equipment and the causes of temperature rise, so as to find out the hidden danger of the accident ahead of time, formulate the maintenance, optimization and rectification plan ahead of time, so as to make sure that there is no danger in preparation and prevent from unburned.
