Abstract

Inventia se refera la un procedeu de obtinere a contactelor electrice sintetizate din argint-grafit, folosite la echiparea sigurantelor automate de 10...25 A si reprezinta o perfectionare a inventiei principale cu descrierea nr. 76848. Procedeul utilizeaza pulberile dozate în mod corespunzator compozitiei dorite de pulbere de grafit cuprins între 1 si 5% care dupa ce au fost presate, concasate si sortate grunulometric sînt presate într-un singur start, sintetizate la 890...920 degree C si calibrate, lipirea de portcontact fiind realizata prin trecerea unui impuls de curent de scurta durata si de mare intensitate.
