VHS2 - *2
Indoor High Voltage Alternating Current Vacuum Circuit
Breaker (Solid Insulation Embedded Pole)
1 General
VHS2 - *2 Series Indoor High Voltage Alternating Current Vacuum
Circuit Breaker is the latest generation of vacuum circuit breaker
with solid insulation embedded pole developed and manufactured by
our company initiatively. It is a kind of an indoor
switchgear used in *2kV power grid as a protective and control unit
for power grid equipment in industrial and mineral enterprises.
Because of particular advantage of vacuum circuit breaker, it
is competently applied in sites where frequent operations in rated
current is required or where short circuit current breaking
operation is often.
1.1 Technical features
The latest generation of series *2kV vacuum circuit breakers.
There is a solid insulation embedded pole in primary circuit.
High quality spring is applied in operating mechanism so that the
mechanical and electrical endurance reach to M2 grade circuit
breaker entirely.
It has successfully passed type test specified by IEC*************8
Standard. The rated short circuit breaking operations are
more than *0.
The vacuum interrupter is introduced from abroad in order to
increase reliability on the whole.

If our customers install this circuit breaker in conditions other
than the above described,
please contact our company to determine permissible scope and
technical measures through
discussion.
