Overheating is the most common cause of failure in incoming panels and bus ducts.
To diagnose internal conditions, the conventional temperature monitoring process involves: measuring the temperature using a temperature sensor → transmitting the signal through an optical or coaxial cable → displaying the temperature on a digital indicator on the front of the instrument panel
It takes a long time to wire the signal line, reducing productivity; in the event of a system failure, the entire signal line must be replaced.
Separate power sources (batteries, DC 5V, etc.) are necessary for the operation of individual temperature sensors and transmission modules.
Batteries need to be replaced every 1.5 years; battery replacements cannot be performed when the lines are live due to safety concerns. When using DC 5V power, each transmitter requires an independent power source; the long amount of time required for wiring reduces production efficiency.
ㅣOPERATING PRINCIPLES AND CONFIGURATION
Energy Harvesting : Use of a magnetic induction coil to collect stray magnetic fields around the bus bar to generate AC voltage
A/D Power Conversion : Conversion of AC voltage into DC voltage to supply operating power to the bus bar temperature sensor and wireless transmission module
Wireless Temperature Transmitting/Receiving : Transmits bus bar temperature from each measuring sensor; displays the temperature on the digital temperature indicator, and saves and records the temperature
