insulating gas or Vacuum Circuit Breaker? - CR4 Discussion Thread

You need to check the Sulfr hexafluoride gas pressure inside the Breaker every month to ensure that the gaz sf6 gas is still O.K. For Vacuum Breaker you don't need to do it because the Vacuum breaker is completed seal. If Sulfr hexafluoride 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. For maintenance cost you need to stand by a cylinder of Sulfr hexafluoride gas inside your substation for filling.Get price
