Digital radiography for inspection of sf 6 | TD Guardian

This varies with the circuit breaker voltage class and if problems are identified during inspection. For a 72-145kV class sf 6 dead tank breaker, two to three exposures per phase are required to provide adequate data. For this breaker size, Siemens can typically complete inspections on one to two breakers per day.Get price

gaz sf6 Circuit Breakers - Construction, Types and Working

In an sf6 gas Circuit breaker, sulphur hexafluoride gas is used as the arc quenching medium. The sulphur hexafluoride gas (sf6 gas) is an electronegative gas and has a strong tendency to absorb free electrons. The contacts of the breaker are opened in a high-pressure flow sulphur hexafluoride (Sulfr hexafluoride) gas and an arc is struck between them.Get price
