Interruption in Air for Different Medium-Voltage Switching Duties


Air is an environmentally benign various to SF6 for use in medium-voltage load-break switches. A easy, axisymmetric take a look at switch has been used for empirical studies of the thermal section of current interruption in atmospheric air. The aim is to quantify how the pressure drop across the nozzle influences the interrupting capability at a different rate of rise of the recovery voltages (RRRVs) and with different current amplitudes. Tests with pressure drops in the vary bar, RRRVs of 40, eighty, and one hundred sixty V/ μs, and currents of three hundred, 60zero, and 900 A were applied. Normally, the present which will be successfully interrupted is proportional with the pressure drop. Likewise, a steeper RRRV needs a proportionally higher pressure drop for the interruption to achieve success. For compact air load-break switches for the important 24 kV/630-A category, it appears sufficient to produce a pressure drop of around 0.twenty five bar lasting for at least twenty ms to go with the “mainly active load” test-sort requirements.
