ALTIPLANO TYPE Summarize
VACUUM CIRCUIT BREAKER
ZN63G4-24 (VS1) The ZN63G4-12 (VS1) vacuum circuit-breakers(VCB) for 24kV rated
voltage are three-pole units which are designed for use in medium-voltage
24kV 50HZ
indoor switchgear. These V circuit-breakers can be used universally for
controlling and protecting the system of power distribution and transmission,
such as power plant, substation, and the like. They are particularly suitable for
use in breaking the important purpose systems and for the switching frequently.
GB1984-2003
The VCBs comply with the provisions of the Chinese Standards GB1984-
JB3855-85 3.6~40.5kV 2003, JB3855-85 and IEC Standards about the V circuit-breakers, and the
IEC interlocking devices are absolutely reliable.
The operating mechanism of the V circuit-breakers is of the stored-
energy type. The closing spring can be charged either manually or by electrical
means and locks into place after sufficient energy has been supplied.
VCB also can configure long life permanent operating mechanism, and
iits mechanism durability is up to one hundred thousand times, It can applicant
10
to very frequency workplace.
VCBs are designed with discrete assembly, and may be used for fixed-
mounted units as well as midship-mounted units fitted with carriages.
Working environments conditions
Altitude: below 4800 meters
Ambient temperature: -15~40 0C
Ambient humidity: dairy average relative humidity less
than 95%, monthly less than 90%
Earthquake grade: less than 8 degree
It should be fixed where is no electrical dust, no explosion,
no corrosive gas, no stronger bounce.
