Title:
CABLE DISCONNECTION SIGN DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/167472
Kind Code:
A1
Abstract:
A cable disconnection sign detection device (201) is connected to a heater (2) which is a load, and detects signs of disconnection of a cable (31) through which current flows to the heater (2). The cable (31) includes a plurality of current paths (CA11, CA12) which are connected in parallel. The cable disconnection sign detection device (201) is provided with: a current detection unit (4) that detects current flowing through at least one current path (CA12) of the current paths (CA11, CA12); and a warning unit (10) that determines the presence/absence of disconnection in the current paths (CA11, CA12) by comparing a value detected by the current detection unit (4) with a threshold value and detecting the conduction states of the current paths (CA11, CA12), and issues a warning when having determined the presence of disconnection.
