Kyle VSA20 and VSA20A air-insulated vacuum reclosers
operate dependably over a long life and require
practically no service other than periodic inspection.
Operating components are designed for long-term
dependability and to withstand the rugged recloser duty.
Inspection is simplified by easy access to the mechanism
and interrupter cabinets; no special tools or procedures
are required.
The recloser operating mechanism employs a 240-Vac
motor to charge the closing spring that in turn provides
the force to close the vacuum interrupters and charge the
opening springs. When tripping and closing operations
are required, springs are released by solenoids actuated
with 24-volt signals from the recloser's electronic control.

Arc interruption takes place within the sealed vacuum
interrupters; consequently, no arcing by-products
contaminate the recloser structure. The interrupters are
mounted independently of the recloser bushings. This
permits quicker bushing replacement and requires no
interrupter adjustment.
Multiple Operations Stored Should the motor supply
be lost while the closing spring is charged, an open-closeopen operating sequence remains stored in the mechanism.
If the recloser trips under these conditions, the stored
closing operation allows an immediate reclosing if
required; after such closing, one further trip operation
then remains stored. Once closed, the recloser always
contains energy for at least one trip operation.
Manual Operations Totally manual operations are
easily achieved while motor power is lost. A hand crank
can be used to charge the closing spring; its release
charges the tripping springs. Closing and subsequent
tripping operations can then be manually actuated at the
operator cabinet or from the recloser control.
Mechanical Life
Open-Close, no load operations ......................... 2500
Reclosing Interval The first reclosing interval may be
configured to operate in less than 24 cycles, followed by a
reclosing interval of 2 seconds.
Quality Vacuum Interrupters
High-quality Kyle vacuum interrupters provide fast, lowenergy arc interruption and exhibit long contact and
interrupter life. Because of their short contact stroke,
operation of the vacuum interrupters causes less stress
and wear on the recloser mechanism, which allows a
longer operating life requiring less service.
Kyle vacuum interrupters employ a metal and ceramic
housing for maximum strength and long-term vacuum
integrity. The high-alumina ceramic is more than five
times as strong as glass, permits a higher processing
temperature to develop maximum purity of envelope
interior, and is impervious to helium penetration to
sustain the vacuum level. Metal components are of highpurity alloys to minimize contamination.
Because the smallest amount of internal contamination
can significantly shorten the interrupter's life, a cleanroom facility is used for interrupter production. Special
care is taken to avoid even minute contamination
whether it be from dust particles, machining oils, or
human body salts.
Superior Control
The Form 6: a powerful, yet flexible recloser control with
all your operating needs met in the front panel design.
One-touch function keys and analysis keys, intuitive
graphical interfaces, and LED indicators with day or
night visibility all simplify training and operation.
ProViewTM software, which operates in a Microsoft
Windows environment, integrates protection, metering,
and automation functions for quick configuration of the
Form 6 recloser control. Innovative control features that
provide new tools for protection, metering, and analysis
include Oscillography, Recloser Replay, directional
functionality, TCC Editor II, and the graphical Idea
WorkbenchTM.
