INTRODUCTION
The following instructions are for field replacement of
interrupters for S&C Series 2000 Circuit-Switchers rated
69 kV through 230 kV.
The Series 2000 Circuit-Switcher interrupter is a porce-
lain-enclosed, hermetically sealed device containing
sulfur-hexafluoride (SF
) gas under pressure. It employs
6
an operating rod which is driven to the open position at
high speed, by means of a power train connected to the
Series 2000 Circuit-Switcher Operator, to effect circuit
interruption. This operating rod is also driven to the
closed position at high speed to effect circuit closing
within the interrupter.
