Title:
CONTACT FAILURE DETECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/135507
Kind Code:
A1
Abstract:
Temperature sensors (Tp, Tm) detect the temperature of a contact section between a live part of a connector (11) of a first circuit device (10) and a live part of a connector (21) of a second circuit device (20). A control unit (24) determines that contact failure has occurred between the live parts when the difference between the variation per prescribed time in temperature detected by the temperature sensors (Tp, Tm) and the variation per prescribed time in ambient temperature is greater than a set value.
