Design of Comprehensive On-line Monitoring Device for High Voltage Switchgear Based on Internet of Things
The authors designed a comprehensive on-line monitoring device for high voltage switchgear based on internet of things. The monitoring unit is for monitoring breaker
MOA arrester
busbar
and contact temperature
and sending the data to switchgear IED through CAN bus
RS-485 bus
Zigbee or other ways. The control unit is for monitoring breaker state
temperature
humidity
etc. in switchgear
displaying the status of switchgear through LCD screen and indicator lights
and electrically controlling the switchgear. The identification unit uses radio frequency identification(RFID)technology to identify the electronic tag pre-embedded in a device for accurately locating and tracking the device. Switchgear IED gathers information of those units
and communicates with station service center in accordance with the protocol of IEC 61850 to realize remote monitoring function.
