      1.Product Overview

      The temperature monitoring points of high-voltage electrical equipment are in the environment of high voltage, high current and strong magnetic field. Even some monitoring points are still in a closed space. Due to strong electromagnetic noise and high-voltage insulation, space constraints, etc., the normal temperature Measurement methods cannot solve these problems and cannot be used. The wireless temperature monitoring system independently developed by our company uses radio waves for signal transmission. The sensor is installed on the high-voltage equipment and has no electrical connection with the receiving equipment. Therefore, the system fundamentally solves the problem that the operating temperature of the high-voltage equipment contact is not easy to be monitored online in real time.

      The wireless temperature monitoring system is extremely reliable and safe, and is relatively inexpensive. It can be mounted directly to each high voltage switch, busbar connector, outdoor knife switch or transformer. The system is equipped with a standard communication interface and can be operated online. Through the PC software, the data of the real-time operating temperature of the high-voltage equipment can be recorded. Providing accumulated data for the maintenance of high-voltage equipment, achieving high-temperature equipment thermal fault-predictive maintenance.
