ZN*3(VS1) - *2
Indoor High Voltage Alternating Current Vacuum Circuit
Breaker
1 General
ZN*3 (VS1) - *2 Indoor High Voltage Alternating Current Vacuum
Circuit Breaker is a kind of *-phase AC *0Hz
high voltage switchgear with rated voltage 7.2kV**2 kV
used as a protective and control unit in electric grid,
industrial and mineral power equipments.
The circuit breaker complies with relevant requirements specified in
China National Standard GB ********3 "High Voltage AC
Circuit Breaker", JB /
T********8 "3.6kV~*0.5 kV Indoor High Voltage AC Vacuum Circuit Breaker",
DL /
T**3 - ***0 "Technical Conditions for Ordering *2kV ~ *0.5kV Indoor High Voltage
Circuit Breaker" as well as those in IEC ****1 - **0 - ***8 "High
Voltage Switchgear and Control gear Part ***0: Alternating
Current Circuit Breaker". In fact,
it offers a very reliable interlocking performance.
ZN*3 (VS1) - *2 Indoor High Voltage Alternating Current Vacuum
Circuit Breaker works with a spring operating mechanism as a
whole. The circuit breaker may be fixed in cubicle as a
fixedly mounted unit or fixed in a pallet as a truck
unit (refer to Fig. 1).
