Sensing apparatus for blown fuse of rectifying wheel and associated methods

摘要: A blown fuse proximity sensing device 40 is for use with a rectifying wheel 37 of type including diodes 38 and associated fuses 42. Each 42 may include housing 51, element 52 carried by the housing, pop-out indicator 54 movable between normal position popped-out position. In position, extends outwardly from responsive to failure element. At least one stationary sensor 44 mounted adjacent positions indicators without contact therewith during rotation thereby sense at fuse. The also local display 61, controller 68 connected generating an indication on display. generate remote output, such as be monitored other plant control equipment.
