Product Launch: VSY1-12 Indoor High-Voltage Vacuum Circuit Breaker
Product Core: A New Generation Modular Vacuum Breaker
The VSY1-12 Indoor High-Voltage Vacuum Circuit Breaker represents the advanced design of a new generation of medium-voltage switchgear. Designed for 12kV distribution systems, it covers a rated current range from 630A to 2000A with a rated short-circuit breaking current of up to 31.5kA. The product features a modular, withdrawable design, integrating vacuum interrupter technology and a spring-operated mechanism, offering advantages such as compact structure, light weight, and long service life. Its core vacuum interrupter seals the arc quenching process entirely within a high vacuum, achieving oil-free, maintenance-free, environmentally friendly, and safe and reliable breaking capability.
Outstanding Performance: Technical Parameters & Environmental Adaptability
The VSY1-12 Breaker defines industry standards with a range of outstanding performance parameters. It boasts not only high breaking capacity (31.5kA) and high dynamic/thermal withstand levels (peak withstand current 80kA, short-time withstand current 31.5kA/4s) but also an impressive mechanical life of up to 10,000 operations and fast operating characteristics (closing time ≤80ms, opening time ≤55ms), ensuring long-term operational reliability and rapid response. The product demonstrates robust environmental adaptability, capable of stable operation across a wide temperature range from -15°C to +40°C, withstanding high humidity, and meeting demanding seismic requirements for altitudes up to 1000m (or higher with special design) and seismic intensity of degree 8.
Application & Value: Protecting Critical Distribution Systems
With its high reliability and compact design, the VSY1-12 vacuum circuit breaker is an ideal choice for various critical power distribution and control systems. It finds extensive applications in industrial and mining enterprise substations, high-rise building distribution centers, urban rail transit power supply systems, and renewable energy (PV/Wind) step-up substations. Its spring energy storage mechanism supports multiple control power sources (AC/DC 220V/110V) with a short charging time (≤15 seconds), facilitating easy remote or automatic operation. By significantly reducing maintenance needs, extending equipment lifespan, and enhancing the safety of the entire distribution system, this breaker offers users excellent lifecycle value and return on investment.
