Vacuum circuit breaker type switchgear KYN28 for medium voltage using
Voltage: 3.6KV 6.6KV 12KV 24KV
Current: 630A 1250A 2000A
Type: withdrawable
Circuit breaker: vacuum
General
The rated voltage of KYN28-12KV switchgear covers 3.6～24kV, three-phase, AC, 50/60Hz, complete set of power distribution equipment for a single busbar segmented system.
It is mainly used for the transmission of small generators in power plants, the power distribution of industrial enterprises, the transmission of power system substations, and the start of large high-voltage motors. The function of the KYN28 switch cabinet is to control, protect and monitor the system.
The KYN28 switchgear we made is in line with IEC and GB3906-91 standards.
It can use domestic VS1, ABB's VD4, Siemens domestic-made 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 functional inspections of the equipment based on the characteristics of each device.
