FUSE BREAKING SENSOR OF A BUILT IN FUSE TYPIC TRANSFORMER OF SWITCH BOARD

摘要

PURPOSE: A fuse disconnection sensing device of a fuse-embedded transformer of a switch board is provided to ease striker insertion and fuse replacement work by moving a device by using an L-shaped cutout unit. CONSTITUTION: A fuse disconnection sensing device (200) is placed on a transformer (100). A horizontal axis (220) is supported to rotate on a pair of brackets (210). A moved lever (230) is separated at regular intervals in a horizontal direction and fixed with the horizontal axis on a position facing a fuse holder (110). A pressurizing lever is fixed with an end of the horizontal axis. A contact sensor (250) is placed to be pressurized when the pressurizing lever is rotated at constant angles. Each of bracket has an opened top part and forms an L-shaped cutout part (215) in directions facing each other.
