Feed control device

摘要

A feed control device (1) includes a contact device (RY), an output detector (22,23,24), a contact weld sensor (20), and an alarm device (LP2). The output detector (22,23,24) is configured to detect the presence of power feeding into the side of an electrically-powered car (100) from an external power supply (PP). The contact weld sensor (20) is configured to sense that the contact device (RY) is welded based on a detection result of the output detector (22,23,24) if detecting the presence of power feeding from the external power supply (PP) to a feed line (L1,L2) for the contact device (RY) when a state signal representing charge permission is not entered. The alarm device (LP2) is configured, if the contact weld sensor senses that the contact device (RY) is welded, to indicate the occurrence of weld to the outside.
