Abstract

FAZ-TOPRAK ARASINDA KISA-DEVRE OLAN ELEKTRİK MOTOR SÜRÜCÜLERİNİN İLK ENERJİ VERİLDİĞİNDE ZARAR GÖRMESİNİ ENGELLEYEN SİSTEM VE YÖNTEM Buluş, endüstriyel senkron tipte elektrik motor (7) sürücülerinin (değişken frekanslı sürücüler, VFD, AFD), ilk enerji verildiğinde hali hazırda evirici (5) çıkış fazları ile toprak arasında bir kısa-devre durumu varsa, bu kısa devre akımının algılanması ve sürücüye zarar vermeyecek şekilde sınırlandırılması sağlayan sistem ve yöntem ile ilgilidir. (Şekil 3)SYSTEM AND METHOD TO PREVENT DAMAGE TO ELECTRIC MOTOR DRIVERS WHICH ARE SHORT-CIRCUIT BETWEEN PHASE-GROUND AT THE FIRST ENERGY INSURANCE. If there is a short-circuit condition between the output phases and ground, it is related to the system and method by which the short-circuit current is detected and limited so as not to damage the drive. (Figure 3)
