In electrical distribution, a fuse or trip fuse is a combination of a fuse and a switch used in primary overhead lines and taps to protect distribution transformers from power surges and overloads. An overcurrent that is caused by a fault in the transformer or in the customer circuit causes the fuse to melt and the transformer to be disconnected from the line. It can also be opened manually by linemen standing on the floor and using a long insulating stick called a “hot stick”.
Components
A section consists of three main components:
The cutout body, an open “C” shaped frame that supports the fuse holder, and a ribbed porcelain or polymer insulator that electrically isolates the conductive parts of the assembly from the carrier to which the insulator is attached.
The fuse holder, also called “fuse tube” or “door”, is an insulating tube that contains the replaceable fuse element. When the included fuse melts (“blows”), it opens the circuit and the fuse holder falls out of the upper contact and hangs on a hinge at its lower end. This hanging fuse holder visibly indicates that the fuse has worked and ensures that the circuit is open. The circuit can also be opened manually by pulling out the fuse holder with a hot rod.
The fuse element or “fuse link” is the replaceable part of the assembly that melts and breaks the circuit when the electrical current flowing through it exceeds its nominal current value.
The fuse holder can be replaced with a fixed blade, which means that the fuse holder assembly can only be used as a switch.
