A wireless temperature monitoring system based on Zigbee technology for high-voltage equipment was designed to detect the overheat-induced fault of switchgear assemblies.The system adopts the distributed hierarchical structure of decentralized measurement and centralized monitoring.The system takes the low-power microcontroller PIC16F690 as its control core and the digital temperature sensor DS18B20 as temperature acquisition device

and uses Zigbee wireless communication module for data communication to achieve a multi-cabinet

multi-channel temperature monitoring.The system has the advantages of low power consumption

good anti-jamming performance

high sensitivity

simple operation

etc.

and it can realize real-time monitoring of temperature for high-voltage equipment

particularly for switchgears

in the enclosed high-voltage

strong magnetic field and large current circumstance.Application of the system demonstrates its merits.
