HHD High Voltage Fuses: The Temperature Limiting Function of The Fuse Striker Pin

FUSES

HIGH VOLTAGE FUSES FOR AIR & GAS INSULATED SWITCHGEARS

GERMAN DIN STANDARD OUTDOOR SWITCHGEARS
The striker pin system is connected by means of a high

resistance parallel conductor. After melting the main fuse
elements the striker pin will indicate the operation status
of the fuse and open a load break switch or actuate a
microswitch for remote indication.
The temperature limiting function

of the fuse striker pin
SIBA HV Fuse-links up to and including 160 A with a
striker pin of 80 N are equipped with an integrated
temperature limiter as standard. The temperature limiter
is fitted inside the striker pin system. The SIBA striker pin
system therefore has the following functions:
• thermal protection of adjacent equipment, especially
SF6 Insulated switchgear
• limitation of failure current at the overload region
• improved properties for the switch-fuse combinations
according IEC 60420
The integrated temperature limiter avoids inadmissible

HIGH VOLTAGE FUSES FOR

AIR & GAS INSULATED SWITCHGEARS
GERMAN DIN STANDARD – GENERAL PURPOSE OUTDOOR SWITCHGEARS
According IEC 60 282-1 and VDE 0670 Part

4, a General-Purpose-Fuse interrupts fault
currents between the rated breaking current
and the current which causes melting within
one hour. The protection range of the SIBA-
VS-Protector extends this basic demand.
The minimum breaking current is about 1.5
times the rated current. In combination with
the temperature released striker pin a full
range protection is possible. Additional fea-
ture is the small powerloss of the VS-Pro-
tector. It is up to 40 % smaller than the
standard DIN-fuse.
The dimensions of the VS-Protector are

according to DIN 43625. The rated voltages
12 and 24 kV and also the available current
ratings allow protection of transformers up
to 630 kVA.
VS-Protector for the overload and
short-circuit range
The function of the VS-Protector is compa-
rable to a typical Back up Fuse link. The
melting elements of pure silver are wound
inside onto a ceramic support. A short
section in the center of the fuse is designed
as a “Heat chamber”. Inside this chamber
the elements are made of silver-alloy. They
generate a certain level of temperature at
overloads. As a result the fuses interrupt at
low fault-currents without ageing.
