Fault Interrupting
through 38kV, 800A, 12.5kA symmetrical interrupting.
G&W Viper-S® solid dielectric,
three phase reclosers combine the time proven reliability
of electronically controlled, vacuum fault interrupters with
the maintenance benefits of a solid dielectric insulated device.
The reclosers are designed for three phase automatic or manual
trip operation providing overcurrent protection for systems
rated up to 38kV maximum, 800A continuous, and 12.5kA rms
symmetrical interrupting. The units can also be used for sectionalizing
and automatic transfer schemes.

Solid Dielectric Technology — Solid dielectric
Viper reclosers utilize G&W’s time proven
EPOX polymer system to fully encapsulate the vacuum
interrupters. This system provides excellent insulation
properties while providing fully shielded, void-free
construction. All modules are UV protected and 100%
factory tested for partial discharge. Dual ratio current
transformers are encapsulated within each module providing
either 500:1 or 1000:1 protection characteristics. CT
ratios can be changed in the field. |
|
Operator
Safety — Vacuum interrupters are sealed
within a solid dielectric insulation. A hookstick operable
manual trip and lockout handle is clearly visible and
easily operated from the ground. The lockout handle
prohibits operation either from the control or remotely
if part of an automation scheme. An open and closed
contact indicators show the vacuum interrupter’s
contact position. Contact status and lockout condition
can also be verified on the control. |
|
Maintenance-free
— Solid dielectric insulation provides a maintenance-free
installation. The magnetic actuator and interface electronics
are located in a separate compartment at the bottom
of the recloser for easy access, if required. |
|
Compact,
lightweight — The solid dielectric Viper
weighs considerably less than comparably rated oil insulated
devices. No special lifting equipment is required. |
|
Latest
Technology Magnetic Actuator — Viper reclosers
utilize the latest in magnetic actuator technology.
This highly efficient actuator consumes very little
energy. The actuator offers superior, repeatable performance
with few moving parts. |
|
Reliable
Performance — The interrupter and magnetic
actuator assembly have been tested for over 10,000 mechanical
operations to assure a long operating life. |
|
Control
Flexibility — Viper reclosers are designed
to work directly with the popular, field proven Schweitzer™
SEL-351R control. Other controls are available depending
on application requirements. |
Manual Trip Operation
For manual open and lockout operation,
a handle is provided permitting hookstick operation. Pulling
the handle down trips and locks out the recloser. A contact
position indicator is provided indicating open or closed status
of the main contacts. The contact status is also displayed
at the recloser control. Operation of the manual open handle
also disables any local or remote closing operation until
the handle is reset. Once reset, the recloser can be closed
using the control.
Sectionalizing Applications
Viper solid dielectric reclosers can be programmed to provide
an ideal solution for sectionalizer applications.
Distributed Automatic
Transfer Applications
Viper solid dielectric reclosers can also be programmed to
provide an ideal solution for overhead applications requiring
distributed automatic transfer switching. The magnetic actuator
permits extremely fast open transfer in under 8 cycles.
Distribution Automation
Proper control selection, applied with the Viper recloser,
provides great flexibility for automated sectionalizing schemes
and other control algorithms. Consult your G&W representative
to discuss specific applications
Padmount Applications
For applications where space is limited at the substation
or where underground feeders require protection, Viper solid
dielectric reclosers can provide an ideal solution using a
standard, dead-front padmount design. In this configuration,
the cable connections can be provided with either a standard
IEEE 600A apparatus or 200A deepwell interface for elbow connectors.
