12kv Vacuum Circuit Breaker

Youbian's durable 12kV vacuum circuit breaker is a 12kV three-phase AC 50Hz outdoor high-voltage switchgear primarily used for switching load current, overload current, and short-circuit current in power systems. The vacuum circuit breaker with a rated voltage of 12kV has a mechanical lifespan of approximately 20000 cycles. The 12kV vacuum circuit breaker adopts a composite insulation structure with high insulation level, no pollution, and no explosion hazard.

Features

The 12kv vacuum circuit breaker uses very suitable contact materials and shapes to ensure low current carrying values and stable contact resistance.

The main electrical circuit adopts composite insulation materials and is designed to be integrated with the operating mechanism.

Less components and parts, compact and reasonable structure, ensuring more reliable and safe operation.

The vacuum circuit breaker adopts a composite insulation structure with high insulation level, no pollution, and no explosion hazard.

The compact design allows it to be installed in almost all switchgear cabinets.

The 12kv vacuum circuit breaker has excellent cost-effectiveness and is the most suitable choice for engineering projects.

advantage

The 12kv vacuum circuit breaker is independent and does not require oil or gas filling. They do not require auxiliary air systems, oil treatment systems, etc. No need for regular refilling.

After the interruption of current, the extremely high dielectric strength can quickly recover, so after the contacts are correctly separated, the arc duration is only half a cycle or shorter.

Current interruption occurs at the first current zero point after contact separation, without the need for reignition, making it particularly suitable for capacitor and cable switching, as well as long-distance line disconnection.

Extremely high power frequency and impulse withstand voltage, small contact spacing, easy operation and timing.

Constant contact resistance. In a vacuum environment, the contacts do not oxidize, so the extremely low resistance of the 12kv vacuum circuit breaker can remain stable throughout its entire service life.
