insulating gas or Vacuum Circuit Breaker? - CR4 Discussion Thread

For sf 6 Breakers there is one Red, Yellow and green lamp to indicate the Sulfr hexafluoride pressure inside the breaker. You need to check the gaz sf6 gas pressure inside the Breaker every month to ensure that the insulating gas gas is still O.K. For Vacuum Breaker you don't need to do it because the Vacuum breaker is completed seal. If sf6 gas breaker gas pressure is less, you can fill it back. But for Vacuum Breaker, if the vacuum inside the breaker leaks you can't vacuum it.Get price
