1. a kind of method that super-pressure potting breaker puts into switching-on resistance, the breaker with switching-on resistance, switching-on resistance withAfter auxiliary contact QF1 series winding, in parallel with main contact QF2 it is characterised in that switching-on resistance is a slide rheostat, close a floodgate specificallyStep is:

  • After auxiliary contact QF1 is closed first completely, drive the slider setting in motion of switching-on resistance, make switching-on resistanceContinuously become minimum value of zero from maximum, make that main contact QF2 is of completely closed simultaneously in switching-on resistance for zero moment, main contact is completeThe slider of switching-on resistance is made to slide back to initial position after closure so that switching-on resistance becomes maximum, then or simultaneouslyAuxiliary contact QF1 is opened, ready for closing a floodgate next time.
