Abstract:
|
Electronic devices combining sensors, wireless
communications, and data processing capability allow easing
predictive maintenance tasks in many applications. This paper
applies this approach in power connectors for high-voltage
electrical substations, which are transformed into smart
connectors. Such connectors are often linked to tubular
aluminum bus bars, whose temperature increases due to the
Joule losses generated by the combined effect of the electrical
resistance and the electric current. Since the human
intervention must be minimized, an energy harvesting system
is required to supply the electronics of the smart connectors.
To this end, a thermoelectric module (TEM) is used to
transform heat power into electrical power. Since the voltage
provided by the TEM is very low, a suitable power converter is
used to supply the electronics of the smart connector. This
work analyzes the effect of the various parameters that affect
the power generated by the TEM when placed on a substation
bus bar. Experiments have been carried out by placing a TEM
with different configurations on different types of bus bars for
diverse operating conditions. |
