Overview of 15.5KV 24KV 38KV Outdoor High Voltage Vacuum Circuit Breaker VCB Integrated Structure Pole Mounted Recloser 630a 1250a

15.5KV 24KV 38KV Outdoor High Voltage Vacuum Circuit Breaker VCB Integrated Structure Pole Mounted Recloser 630a 1250a is a type of circuit breaker where the arc quenching medium is a high vacuum. Unlike older breakers that used air, oil, or SF6 gas to extinguish the electrical arc, a VCB utilizes the superior dielectric properties of a vacuum to rapidly extinguish the arc when the contacts separate, thereby interrupting the current flow and protecting the electrical system.

Specifications of 15.5KV 24KV 38KV Outdoor High Voltage Vacuum Circuit Breaker VCB Integrated Structure Pole Mounted Recloser 630a 1250a

This outdoor high voltage vacuum circuit breaker (VCB) handles demanding power distribution. It’s built for tough conditions. It works reliably on utility poles. This unit combines the breaker and recloser functions in one compact structure. This integrated design saves space and simplifies installation. It’s ready for pole mounting right out of the box.

The breaker operates effectively at common distribution voltages. It supports 15.5 kilovolts (KV), 24 kilovolts (KV), and 38 kilovolts (KV) systems. It manages significant electrical current. Choose between a 630 amp (A) or a 1250 amp (A) continuous current rating. This flexibility suits different grid requirements.

Vacuum interrupters inside the breaker ensure dependable fault current interruption. This technology offers high dielectric strength. It provides excellent arc quenching capability. This results in long service life and minimal maintenance needs. The vacuum chamber is sealed for life. This prevents environmental contamination.

The integrated recloser function is a major advantage. It automatically tries to restore power after temporary faults. This feature minimizes outage durations. It reduces the need for crew dispatches. The recloser logic is programmable. Operators can set specific sequences and timing delays. This protects equipment and improves grid reliability.

The entire assembly is designed for harsh outdoor environments. It withstands extreme temperatures. It resists rain, snow, dust, and UV exposure. Corrosion-resistant materials protect critical components. The robust construction ensures dependable operation year-round. It handles demanding switching duties. This breaker provides safe isolation for line maintenance.

Applications of 15.5KV 24KV 38KV Outdoor High Voltage Vacuum Circuit Breaker VCB Integrated Structure Pole Mounted Recloser 630a 1250a

These outdoor high voltage vacuum circuit breakers handle tough jobs on power lines. They work well at 15.5kV, 24kV, and 38kV levels. Their integrated VCB structure makes them strong and dependable. You see them often on utility distribution networks. They protect overhead lines feeding towns, factories, and big buildings. Their job is to stop faults quickly. This keeps the power flowing for everyone else.

Utilities mount them directly on poles. This saves space and money. They don’t need expensive substation buildings. The 630A and 1250A ratings handle heavy currents. This is essential for main feeder lines. They automatically cut power during short circuits. This prevents damage to transformers and other equipment.

These breakers act as reclosers too. That means they try to restore power fast after a temporary fault. Think of a tree branch hitting a line. The breaker opens. Then it closes again quickly. If the fault is gone, power comes back on. People experience fewer long outages. If the fault stays, the breaker locks open. Crews then find and fix the problem.

Substations use them for protection. They guard important transformers or capacitor banks. Their vacuum interrupters stop arcs inside. This is safer than older oil breakers. They need less maintenance. This saves time and money for the utility. They work reliably in bad weather. Rain, snow, or dust don’t stop them.

Rural areas benefit greatly. Long distribution lines need protection. These pole-mounted units provide it. They isolate faults far from the main substation. This keeps power stable for farms and small communities. Industrial sites use them too. They protect private power distribution systems. Factories need reliable electricity. These breakers help deliver that. They are a key part of keeping the lights on.
