Intelligent wireless temperature measuring device of ring network cabinet
model：DX-WPS100-HCW
1、 Demand analysis
With the acceleration of urbanization, the demand for power transmission is also increasing. In the long run, it has brought a great burden to the ring network cabinet. If the temperature detection system fails to respond quickly to warn, it will accelerate the damage of the ring network cabinet, and even cause fire, electric leakage and other accidents. Therefore, a set of reliable intelligent wireless temperature measurement device for the ring network cabinet is very necessary.
Our ring network cabinet intelligent wireless temperature measuring device is widely used in high and low voltage switchgear, ring network cabinet contacts, knife switch, high-voltage cable connectors, dry-type transformers, low-voltage high current cabinets and other electrical equipment.
2、 Working principle
The intelligent wireless temperature measuring device of the ring network cabinet consists of a wireless temperature measuring sensor, a wireless temperature receiving terminal, a data server and a background. The wireless temperature measuring sensor monitors the surface temperature in real time, transmits the monitored temperature data to the wireless temperature receiving terminal, and the wireless temperature receiving terminal transmits the data back to the data server and the background through wireless and optical fiber, The user can monitor and view the on-site real-time temperature of each sensor through the browser. If there is overheating, the user can quickly locate and timely notify the relevant personnel.
