<p><P>PROBLEM TO BE SOLVED: To provide a live wire cutting support device capable of cutting off live wires while suppressing the occurrence of noises with a simple configuration. <P>SOLUTION: A live wire cutting support device comprises a pair of connecting cables connectable to the both ends of a place at which a wire is to be cut off, and a circuit in which a plurality of switching circuits are connected in parallel, the switching circuits each composed of a series circuit with a resistor and a relay contact, the resistance values of the resistors differ depending on the respective switching circuits. The live wire cutting support device further comprises switch control means for controlling the on/off state of the relay contact. The switch control means may be configured to be capable of controlling the on/off state of the relays only in a predetermined sequence, and may have an automatic cutting function. It follows that the live wire cutting support device can cut off live wires while suppressing the occurrence of noises with a simple configuration, and can reduce heat generation and allows itself to be miniaturized. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
