Fault
interrupting to 50kA symmetrical.
For applications through 23kV requiring current limitation
and overcurrent interruption through 50kA
symmetrical,
SF6 switches can be equipped with integral air insulated,
canister style current limiting fusing.
G&W's
circular tank rotary puffer (RP) switch incorporates all bushings
and operating apparatus on the top of the switch. Switches
are rated through 23kV, 200A maximum continuous current.
Protected ways are rated per Table 3 (see bottom of page).
Two way and three way configurations are available for either
single, two or three phase applications. Single and
parallel fuse holders are available.
| Features:
|
Mechanical
interlock prevents fuse access if switch is in the closed
position. |
 |
Compact, dead-front construction. |
|
Mechanical
or key interlocking arrangements preventing access to
the fuses unless the switch is in the open position. |
|
Safe,
quick fuse replacement using conventional tools and
without exposing switch dielectric or current carrying
parts to environmental contamination. |
|
Two
fuses can be connected in parallel to double the capacity
rating of the switch. |
|
Fuse
curves are available through your G&W representative. |

| Typical
Specifications |
| Add
the following information to the appropriate fused switch
specifications. |
| Canister
Fusing Construction |
|
Fusing
shall be deadfront and submersible using non-venting,
current limiting fuses installed in drywell canisters
built into the switch. The fuses shall be ANSI
C37.473.C rated, interrupting both high and low level
fault currents while limiting the available fault current
on the system.
The
fuseholder shall be located for easy fuse replacement
and be interlocked to prevent fuse removal unless the
series switch is open. |
Standard
hook stick fuse removal and replacement. |
| Standard
Components |
|
Replaceable and interchangable,
commercially available, general purpose current limiting
fuses. |
|
Provisions for standard hook stick
fuse removal and replacement. |
|
Single or parallel fuseholders as specified. |
