Equipment for the direct current system section
Effectiveness and cost-savings: a complete and reliable range
of products from ABB experience.
Since increasingly higher values tend to be used (to reduce
losses), ABB developed specific products to meet the various
system engineering needs, reducing the costs for systems
up to 500 V and optimizing performance for higher voltage
values.
S800 PVs are available both in the switch-disconnector
version (S800 PV-M) and in the circuit-breaker version
(S800 PV-S) and are the most compact circuit breakers in the
market for protecting direct current circuits. This line is now
complemented by the miniature circuit-breaker S284 UC, Z
curve, that can reach 500 V d.c. with sizes up to 16A.
All the accessories typically provided with the standard
modular products are available: voltmeter shunt trip or
undervoltage releases, auxiliary contacts and fault signal
contacts.
For single string protection in large-sized systems, compact
modular fuse disconnectors are provided, capable of housing
10x38mm fuses with voltage up to 1000 V d.c.
To guarantee maintenance operators safety, the use of the
DC20 fuse disconnector (i.e. that can operate on the circuit
only with no load) must be combined with DC21 switch-
disconnectors.
For string and inverter protection, ABB also developed a
range of products dedicated to the complex protection
against surges of atmospheric origin on DC side.
The OVR PV surge protection devices are specifically targeted
at this kind of application, with a Y connection for systems up
to 1000 V. The Gemini series IP66 switchboards can be
optimally used as string boxes or parallel boxes, i.e. for
installation outdoors next to the modules. With its unequalled
range, ABB developed a number of “plug & operate”
solutions, that is a number of finished, wired and certified
switchboards to meet the needs of the most varied types of
installations: from the single string for residential applications
to the large solar farms.
