Siemens launches highly customizable generator circuit-breaker

The HB1-C generator circuit-breaker
These customizable features make the HB1-C not only suitable for new applications,
but also valuable for retrofit scenarios in power plants where security of
supply is essential, and space is often limited. The HB1-C is to be showcased at Enlit Europe, taking place in Frankfurt
from November 29 to December 1.
With increased focus on renewable power and cost reduction front of
mind, reliable protection technology is crucial. Generator circuit-breakers are
vital components for improving the reliability and availability of power
plants. Their installation not only protects equipment such as generators and
transformers against overload or short circuiting, but also provides high
availability, simplified operational procedures and a reduction in costs.
Manitoba Hydro, the electric power and natural gas utility in the
province of Manitoba, Canada is set to reap the rewards of the new HB1-Compact
model. Thanks to a contract with Siemens Canada, Manitoba Hydro will install up
to twelve replacement generator circuit-breaker systems in its 1,220 MW Kettle
Generating Station, located on the lower Nelson River in Manitoba. The contract
underpins a long-term relationship between Siemens and Manitoba Hydro, as the
two organisations work together to extend the life of this important generating
station and to continue to deliver clean, renewable, and dispatchable energy
for the province of Manitoba.
Offering the highest levels of customization, the HB1-Compact model provides
power plant operators with the greatest degree of flexibility when designing a
new plant or replacing outdated equipment. Designed with reliability also at
its core, the HB1-C’s full-spring operating mechanism has been selected by
CIGRE as the most reliable way to operate a generator circuit-breaker with a
lifespan of up to 10,000 operating cycles. With all components and functions
type and routine tested together, the HB1-C delivers a native interlocking
system with the highest levels of reliability and safety. Indeed, to guarantee
safe maintenance, the circuit-breaker can be fitted with integrated line and
earth disconnecting switches.

Circuit-breaker in I-shape design

Also available in L-shape
With cost savings a key concern for many plant operators, the HB1-C is
designed to reduce costs during the project implementation and ongoing operations.
Its simple and compact design means that transport costs are reduced and outage
times for the installation of a new circuit-breaker are minimal. Costs are
further reduced thanks to the maintenance-free vacuum switching technology which
eliminates the need for gas handling, guarantees minimum maintenance costs and
increases the recycling rate of the systems.
