TABLE OF CONTENTS

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

 

6

 

) gas under pressure. It employs

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.

WARNING

 

 

 

The equipment covered by this publication must be
installed, operated, and maintained by qualified per-
sons who are knowledgeable in the installation, oper-
ation, and maintenance of electric power distribution
equipment along with the associated hazards. A quali-
fied person is one who is trained and competent in:

 

 

The skills and techniques necessary to distinguish
exposed live parts from non-live parts of electrical
equipment.

 

 

The skills and techniques necessary to determine
the proper approach distances corresponding to
the voltages to which the qualified person will be
exposed.

 

 

The proper use of the special precautionary tech-
niques, personal protective equipment, insulating
and shielding materials, and insulated tools for
working on or near exposed energized parts of
electrical equipment.

These instructions are intended only for such qual-

ified persons. They are 

 

not 

 

intended to be a substitute

for adequate training and experience in safety proce-
dures for this type of equipment.
