本計器 는 정류형 廣角(광각)과 可動鐵片型(가동철편형) 및 可動 Coil형으로
제작되 며 정류형은 가동철편형에 비하여 舟臼?小負荷(소부하) 에도 정확하게
측정할 수있습니다
1.Motor에 使用할시는 정격전류 100~500%에 해당하는 초과 눈금 (적색지시)을
그려서 Motor의 기동부하 충격을 防止(방지) 하며 電流計 의 수명을 연장시킨다. 2.교류 電流計는(C.T)
직류電流計는(SHUNT)를 外部 附着使用 하여야 한다. 3.計器의 하단에 쑥색바탕의 OUT A-meter(그림참조) MAIN
A-meter등으로 표시되어 있으므로 별도의 조각이 필요없습니다.
The types of operating principle of ammeter are the
rectifier type , the moving iron type and the moving coil, and the rectifier
type ammeter has a merit of measuring small current value compared with
moving iron type.
1.The scale range of ammeter for motor circuit is
extended up to 150-500% of current, so that these meters are protected from the
impct of the starting current and ensured of long life. 2.A.C ammeter is used
with a current transformer extemally mounted, and it is noted that promary
current of a surrent transformer and a full scale of the meter are identical
when used. 3.D.C ammeter is used with a shunt, it is noted that a full scale
and a terminal voltage(50mv,60mv) of the ammeter are same as the rated primary
current and seconday voltage of the shunt respective. |
