Dimension drawing:
Q: What inspections should be performed after a short-circuit fault in a vacuum circuit breaker?
A:
Check contact erosion: Minor erosion is acceptable (cumulative wear ≤3mm), but replace the vacuum interrupter if damage is severe.
Test switching time and synchronization: Ensure values meet specifications to prevent operational issues caused by mechanism changes.
Clean arc byproducts: Remove debris from the interrupter surface and inspect insulation components for impact damage or cracks.
Q: What are the differences between indoor vacuum circuit breakers and SF₆ circuit breakers?
A:
Arc-quenching medium:
Vacuum circuit breakers use vacuum for arc quenching (environmentally friendly, no greenhouse gases), while SF₆ circuit breakers use SF₆ gas (requiring attention to gas leakage and environmental treatment).
Volume and maintenance:
Vacuum circuit breakers are smaller in size and have a longer maintenance cycle (the maintenance-free cycle can reach 10 years); SF₆ circuit breakers require regular detection of gas pressure.
