The VS1-12/24/33(ZN63A) model is an indoor high-voltage vacuum circuit breaker rated at 12kV, three-phase AC 50Hz. It is designed
for indoor high-voltage switchgear, featuring a spring operating mechanism for both manual and electric operations, ensuring a
combination of protection, control, and circuit breaking. It is suitable for use in places like mines, factories, substations, and
switchyards where the device can handle the demands of frequent operations and monitor current loads.
Operating Environment
Ambient temperature range: -10°C to +40°C (storage allowed at -30°C);
Altitude: ≤1000m;
Relative humidity: Daily average ≤95%, Monthly average ≤90%, Absolute humidity ≤2.2x10³ MPa; daily average water vapor pressure ≤1.8x10³ MPa. During high temperatures, condensation may occur;
Ambient temperature should not exceed 35°C;
No presence of fire, explosion hazard, severe pollution, chemical corrosion, or severe vibration environments.
Structural Features
Insulating Components
The VS1 vacuum circuit breaker uses ceramic or glass vacuum interrupters with metal bellows, featuring
vacuum contact materials and high-pressure forming of sealed insulating enclosures. The contacts have high
dielectric strength, stable pressure, low contact resistance, and enhanced current-carrying capacity with
strong arc-extinguishing performance.
Framework
The VS1 vacuum circuit breaker adopts a modular design with a spring mechanism and vacuum
interrupters enclosed within a tubular insulating framework. The breaker can be installed directly or in
switchgear cubicles,
allowing for applications in electrical distribution, factories, and substations. The enclosure ensures high
stability and protection against adverse environmental conditions like severe pollution or humidity.
Performance
The VS1 vacuum circuit breaker has reliable performance, long mechanical and electrical life, requiring
minimal maintenance, and can withstand harsh environments such as humidity, dust, and frequent switching
operations.
Operating Mechanism
The VS1 vacuum circuit breaker utilizes a spring-charged operating mechanism that can be operated
manually or electrically. The operating mechanism ensures the circuit breaker can be charged, closed, and
opened reliably.
This operating mechanism is highly reliable, has fewer mechanical parts, and ensures smooth operation,
making the VS1 vacuum circuit breaker suitable for frequent operation scenarios with high operational
efficiency and minimal noise and vibrations.
Working And Operating Principles
Arc Extinguishing Principle
The VS1 vacuum circuit breaker extinguishes arcs using a vacuum as the insulating medium. When the
contacts separate, the arc is forced to spread and extinguish rapidly due to the magnetic field generated within the
vacuum interrupter, which effectively cools and condenses the arc plasma. This arc extinguishing process
occurs quickly and reliably, minimizing contact wear and ensuring stable operation.
Energy Storage
The sophisticated energy storage system of the VS1 vacuum circuit breaker is expertly designed with a motor-driven mechanism that efficiently winds the energy storage springs.
Once these springs are fully charged, the breaker stands ready for seamless operation. This engineering marvel ensures an unwavering commitment to operational readiness.
Our innovative mechanism is crafted for unparalleled reliability, guaranteeing stable and swift energy release during crucial switching operations.
Closing Operation
Upon receiving a precise closing command, the energy stored within the closing springs is expertly unleashed, propelling the contacts together with impressive speed.
This advanced mechanism assures a swift and dependable closing action, catering to a diverse array of applications that demand exceptional operational performance.
applications demanding high operational performance.
Opening Operation
During opening operations, the breaker harnesses the stored energy in the opening springs, releasing it with precision upon receiving an opening command.
The rapid discharge of this energy forcefully drives the contacts apart, effectively interrupting the current flow and extinguishing the arc within the vacuum interrupter.
This meticulously engineered action ensures safe and effective circuit breaking, safeguarding your systems with excellence.
