Product Description

VS1-24 series indoor vacuum circuit breakers are indoor high-voltage switchgear with rated voltage 24KV and three-phase AC 50Hz. They are suitable for control or protection switch of transmission and distribution system such as power plants, substations and industrial and mining enterprises, especially suitable for breaking important loads and frequent operation places in high altitude areas.
Circuit breakers are manufactured in line with China's national standards GB1984-2003, DUT403-2000 and related IEC standards, and have reliable interlocking function.
The operating mechanism of the circuit breaker is spring energy storage type, which can be operated by AC and DC energy storage, and can also be manually operated.
At the same time, the circuit breaker can be equipped with a long-life permanent magnet operating mechanism, and the mechanical life can reach 60,000 times, which can be used for extremely frequent operations.
The circuit breaker is designed to be a front and back split structure, which can be used as a fixed installation unit or a mid-mounted unit with the chassis car.

 

Service Environment

1. Ambient temperature: upper limit +40 degrees, lower limit -15 degrees.
2. Altitude: The altitude is not higher than 1000m.
3. Relative humidity: daily average is not more than 95%, monthly average is not more than 90%, saturated vapor pressure: daily average is not more than 2.2kPa, monthly average is not more than 1.8kPa.
4. Earthquake intensity: Less than magnitude 8.
5. The amplitude of electromagnetic interference induced in the secondary system does not exceed 1.6kV. It is required to be installed in a place without fire, explosion danger, corrosive gas and violent vibration.
