Abnormal LeakageInternal FaultExternal FireThe method of risk assessment is similar to that used in section "leakage from SF6 – filled equipment" which deals with normal leakage. The same case study data will be used for high and medium voltage situations. In the calculations that follow it is assumed that all of the SF6 in one circuit breaker escapes suddenly and it is again assumed that the switch room is sealed and that ventilation is inoperative. (see figure 1). In practice, atte…See more on electrical engineering portalReviews: 1Published: 2017/6/28Estimated Reading Time: 8 minsA Comparison Between Vacumm and SF6 Circuit Breakers iderparts.co.uk/a comparison between vacumm and sf6 circuit breakers b 39The toxic value, which is directly dangerous for human health, of SF6 gas, which has been switched on and used several times in arc extinguishing, becomes very high. In addition, the high pressure of the SF6 circuit breakers transforms heat activated bursts in the event of possible failure during short circuit switching, which creates a serious safety problem.
