與傳統的鐵芯材料矽鋼和坡莫合金(jīn)相飛對比較,鐵基納米晶合金(jīn)具有高磁導率、低(d呢好ī)損耗的明顯優勢,測量電流範圍更廣。
Applications
Current transformer of p東得ower system plays an i答吧mportant role in prov藍什iding a current in its secondary中熱 winding proportional to the altern資短ating current flowing in its primary做年. They are commonly us購工ed in metering and protective relayin黑這g in the power plants and s黃長ubstations where they facilitate t做藍he safe measurement of large current北姐s, often in the presence of hig什文h voltages. The current transformer sa制雨fely isolates measurement and control 又機circuitry from the high voltages typica兒短lly present on the circ議北uit being measured.
Comparing with the traditional core mat黃小erial, such as silicon steel and 聽也permalloy, Iron based nano議兒crystalline alloy takes the advanta鄉從ge of high permeability and藍工 low cost, it is more competitive in照國 the application of prec姐了ision current transformer with 0.2,0.2兵師s,0.1 accuracy class, B見員ushing current transformer for Epoxy r但現esin cast, Gas insulate理遠d or oil-immersed switchgears子刀, LV, MV and HV switchgear, and 司生other apparatus in electric 長議power transmission an土得d distribution syste花遠m.
