Three abnormal situations leading to an uncontrolled release

Abnormal leakage. The method of risk assessment is similar to that used in section “leakage from Sulfr hexafluoride – filled equipment” which deals with normal leakage. Internal fault. An internal fault can develop when an arc is formed abnormally between the main conductors of an item of switchgear, or between a main conductor and an earthed conducting part. External fire. Fires in outdoor installations rarely cause problems because of the relative absence of flammable material in the vicinity of the switchgear.

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 sf6 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 Sulfr hexafluoride 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 Sulfr hexafluoride would be in the atmosphere, leading to an SOF2concentration of 1,8 ppmv. In the case of abnormal leakage of Sulfr hexafluoride in a medium voltage indoor substation (see figure 2 ), the SOF2 related to complete escape of Sulfr hexafluoride 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
