Withdrawable vacuum circuit breaker for medium voltage use KYN28A-12
Voltage: 12KV
Current: 630-2000A
Type: withdrawable
General
The rated voltage of KYN28-12KV indoor switchgear is 3.6～24kV,
three-phase, AC, 50/60Hz, single bus or single bus segmented system
complete set of power distribution equipment. It is mainly used for
the power transmission of small generators in power plants, the
power distribution of production enterprises and the power
transmission and transmission of substations in the power system,
and the start of large high-voltage motors. The role is to control,
protect and monitor the system.
It conforms to IEC and GB3906-91 standards, and can be used with
vacuum circuit breakers such as domestic VS1 vacuum circuit
breaker, ABB's VD4, Siemens domestic ZN65A 3AH5, GE's VB2 and other
vacuum circuit breakers.
Service environment
1. Air temperature: -25℃~+40℃
2. Humidity:Monthly average humidity 95%; Daily average humidity
90% .
3. Altitude :≤ 2500m
4. Ambient air not apparently polluted by corrosive and flammable
gas, vapor etc.
5. No frequent violent shake
Fully type-tested
The device passes all tests required by international (IEC)
standards. When each switchgear goes through regular factory tests
before leaving the factory.
These tests are a functional inspection of the equipment based on
the characteristics of each device.
