Contact and nozzle wear from 100 interruptions for a puffer-type air load break switch

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1475813

One type test requirement for medium voltage load break switches is to interrupt 100 consecutive "mainly active loads". A puffer-type switch with axial-blown arc has been tested according to the 630 A/24 kV ratings. The nozzle and contact wear were measured regularly to investigate design requiremen...

Empirical Relationships between Air-Load Break Switch Parameters and Interrupting Performance

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1251486

A simple gas blow switch consisting of an axisymmetric tulip/pin contact and a cylindrical polytetrafluoroethylene (PTFE) nozzle has been used for empirical studies of medium voltage load current interruption in air. Only the thermal phase of the interruption is considered. Based on the results of m...

Arcing voltage for a medium-voltage air load break switch

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1286157

Air is an environmentally benign and attractive alternative to SF6 as arc quenching gas in switching devices for modest current and voltage ratings. Several interruption tests with a simple air medium-voltage load break test switch have been carried out to investigate the arc and the arcing voltage ...
