Three abnormal situations leading to an uncontrolled release

Abnormal LeakageInternal FaultExternal FireThe method of risk assessment is similar to that used in section “leakage from insulating gas – 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 gas 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, attention would be drawn to an abnormal leak by underpressure detectors fitted to the CBs. These normally operate around 80% of normal filling pressure, and at this point in time, only 20% of the available sf 6 would be in the atmosphere, leading to an SOF2concentration of 1,8 ppmv. In the case of abnormal leakage of sf 6 in a medium voltage indoor substation (see figure 2 ), the SOF2 related to complete escape of sf 6 from one CB would reach 17,5 ppmv. The concentration of SOF2in the switchroom at 20% relative pressure loss (commonly the alarm level) w...Get price
