Abstract

As the switch contacts and the bus are in high voltage, each Phase-to-ground and different phase has high voltage, monitoring of high voltage switchgear electrical junction temperature is always a difficult problem. Face this Special working environment, ZigBee wireless transmission technology can complete the wireless signal transmission channel, solve the high-voltage sensor modules; power supply and high-voltage isolation between the low voltage control modules, signal transmission. This article introduces the ZigBee technology; describe the theory of temperature measurement based on ZigBee technology, ZigBee transfer Protocol and ZigBee workflow. Designed electrical junction temperature measurement system based on ZigBee technology.
