From US-based Cooper Power Systems comes a
revolution in distribution switchgear. The
three-phase, microprocessor-controlled Nova recloser
(from subsidiary Kyle Distribution Switchgear) uses
advanced polymer and vacuum technologies to deliver
outstanding performance and durability.
The Nova family of switchgear products, distributed
in New Zealand by Arthur D Riley & Co Ltd, utilises
a state-of-the-art design which completely replaces
liquid and gas dielectric mediums, making them not
only environmentally-friendly, but also
maintenance-free.
SF6 gas (sulphur hexafluoride), which has
traditionally been used in switchgear in the past,
is considered a particularly nasty gas, and has been
classed among the most potent of greenhouse gases.
It is heavier than air and does not readily
disperse, thus creating hazards in confined areas.
Regulations regarding monitoring the gas,
inspection, work rules and procedures add to the
overall cost of operating and maintaining equipment.
Nova’s solid insulation system beats this problem
once and for all. The recloser combines solid
cycloaliphatic-epoxy polymer-encapsulated vacuum
interrupters with a lightweight operating mechanism,
which utilises a magnetic actuator to provide a
lifetime of trouble-free recloser operation. Because
solid dielectric insulation eliminates the need for
insulating gas or liquid, it means there is no need
to monitor gas pressure or oil levels, to filter or
replenish the dielectric, take special precautions
when handling the dielectric, or worry about
environmental regulations regarding disposal of
environmentally unfriendly materials.
Vacuum interruption, used in the reclosers, provides
greatly enhanced contact life. A single break on
each phase is achieved by separating contacts inside
the interrupter. All arcing is contained within the
vacuum envelope, and low-energy arc interruption,
provided by axial-magnetic field technology, results
in far less mechanical shock, extending the
recloser’s mechanical life.
The Nova family of switchgear products is designed
and manufactured in accordance with ANSI C37.60.
