Product Description

Effciently Safely Power Plant Substation 12kV Indoor Vacuum Circuit Breaker

 

Product Description: 

Vacuum circuit breaker is a special type of electrical circuit breaker that is designed to rapidly open and close.

Unlike circuit breakers, which are designed to “trip” and stay in the open state, it can rapidly transition states from

closed, to open and back. These devices aim to stop network faults from causing long outages, by quickly restoring power.

 

Vacuum circuit breaker is the automatic configuration of a circuit breaker to close after opening due to a protection

operation. It is used in both Medium Voltage distribution and High Voltage Transmission, although in slightly different

ways. Distribution VCB uses standalone autoreclosers, such as the Recloser product, which has an integrated control

system, an HV Reclosing Circuit Breaker and a Remote SCADA FTU.

Application

Substation 12kV Indoor Vacuum Circuit Breaker For Power Plant 6

Advantages

1.Vacuum circuit breaker can greatly improve the reliability of overhead distribution networks by mitigating

the impact of momentary faults.

2.Vacuum circuit breaker reduce outages from these transient sources, increasing uptime of power supply.

3.Utilities that deploy reclosers for their overhead distribution networks experience significant reliability improvements.

4.Longer product service life and more resilience to bad weather.
