<p><P>PROBLEM TO BE SOLVED: To provide a lamp wick breakage detection/processing device capable of securing safety of a personnel for maintaining and exchanging a lamp and improving efficiency of a maintenance work. <P>SOLUTION: A voltage generating part 22 is serially connected to a bypass circuit 15 closing when the wick of the lamp 12 is broken. The voltage generating part 22 makes current from a secondary side of a current transformer 11 flow and generates a prescribed voltage when the wick of the lamp 12 is broken and the bypass circuit 15 is closed. An arithmetic control circuit 14 determines that the breakage of the wick of the lamp 12 is restored, when a current detection circuit 16 detects a current flowing through the lamp 12 by the voltage of the voltage generating part 22, while a contact 15a of the bypass circuit 15 is closed. Accordingly, high voltage is never to be generated when restoring of the breakage of the wick of the lamp 12. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
