Switchgear Innovation: Comparing Vacuum vs. SF6 Circuit Breakers
Analyzing insulation performance, environmental impact, and maintenance intervals for medium-voltage grid distribution switchgears.
1. Vacuum vs. SF6: The Arc Extinction Medium
Medium-voltage switchgears require reliable circuit breakers to clear electrical faults. Vacuum circuit breakers (VCB) and Sulfur Hexafluoride (SF6) gas circuit breakers are the primary technologies.
VCBs use a vacuum chamber to quench electrical arcs. They are maintenance-free and environmentally friendly. SF6 breakers offer excellent insulation performance but require gas pressure monitoring due to greenhouse gas regulations.
