Abstrakty

The flow of significant current through electric contacts may lead to contact welding. In a.c. circuits this phenomena is not only dependent on properties of contact material (i.e. resistance to welding) but on the phase in which current is switched on. Welding tendency for contact materials made from AgNi, AgCdO and AgSnO2 was evaluated based on selected phase at which make operation took place. The test circuit was protected by overcurrent apparatus to simulate real working environment. It is observed that welding tendency for the selected contact materials is contingent to current phase at which make operation is done.

Przepływ znacznego prądu przez styki elektryczne może prowadzić do ich sczepienia. W obwodach prądu przemiennego to zjawisko jest nie tylko zależne od właściwości materiału stykowego (tj. odporności na sczepianie), ale od fazy, w której prąd jest załączany. Zbadana została tendencja do sczepiania się styków, w zależności od fazy załączania prądu, wykonanych z następujących materiałów stykowych: AgNi, AgCdO i AgSnO2. Obwód probierczy zabezpieczony był przez zabezpieczenia nadprądowe, w celu symulacji normalnych warunków pracy. Zauważono, że tendencja do sczepiania styków, dla wybranych materiałów stykowych, jest zależna od fazy, w której wykonuje się załączenie obwodu.
