METHOD FOR DETERMINING AN OVERHEAT OF AT LEAST ONE CONNECTION TERMINAL OF AN ELECTRICAL DEVICE, ASSOCIATED AUXILIARY APPARATUS AND ELECTRICAL SYSTEM COMPRISING SUCH AN ELECTRICAL DEVICE AND SUCH AN AUXILIARY APPARATUS

摘要

In this method of determining, with the aid of an auxiliary apparatus (24), an overheating of at least one connection terminal (38, 40) of an electrical device (22), the terminal or terminals of connection (38, 40) each comprising at least one own connection pad to be connected to a corresponding electrical conductor (12 ', 14'). This method comprises, for each connection terminal (38, 40), steps for measuring a first temperature, at a given instant, for calculating a thermal value of the connection range, for comparing the thermal value of the range. connection with a temperature threshold, and detection of an overheating of the connection terminal (38, 40) corresponding when the thermal value is greater than the temperature threshold. The method comprises previously in the comparison step and for each connection terminal (38, 40), a step of calculating the temperature threshold at the given instant, as a function of the value of the threshold at a previous instant, the value the temperature threshold being variable between the previous instant and the given instant.
