Detailed Solution
Download Solution PDF- पूर्वग्रहज व्यय ही एक प्रकारचा ऊर्जा हानी आहे जी विद्युत यंत्रांमध्ये लोह क्रोडची पुनरावृत्ती आणि निकर्षणामुळे होते.
- पर्यायी प्रवाहाच्या प्रवाहामुळे, लोह क्रोड प्रत्येक चक्रात चुंबकीकृत आणि विचुंबकित होतो आणि चुंबकीकरणाच्या प्रत्येक चक्रादरम्यान, काही ऊर्जा नष्ट होते.
- सामग्रीमध्ये होणारे पूर्वग्रहज व्यय असे आहे,
- \({W_h} = KfB_m^{η}\)
- \({W_h} = \eta \times B_m^{1.6} \times f \times V\)
-
Where,
η हा स्टाइनमेट्झचा स्थिरांक आहे
V हा गाभ्याचे आकारमान आहे
f ही पुरवठा वारंवारता आहे
Bm ही चुंबकीय अभिवाह घनता आहे
-
पूर्वग्रहजशी संबंधित ऊर्जेचा व्यय पूर्वग्रहज वेढ्याच्या क्षेत्रफळाच्या समानुपाती असतो. नमुन्यासाठी पूर्वग्रहज वेढ्याचे क्षेत्रफळ मोठे असल्याचे आढळल्याने, या नमुन्यातील पूर्वग्रहज व्यय देखील मोठा आहे.
