Kev faib tawm thiab kev siv ntau yam ntawm cov zaub ammeter
Cov duab digital ammeter hloov cov teeb liab loj tam sim no rau hauv lub teeb liab me me los ntawm lub micro tam sim no transformer, thiab tom qab ntawd dhau los ntawm AD analog-to-digital converter thiab cov khoom siv hluav taws xob los kho cov teeb liab tus nqi los ntawm LED cov raj lossis LCD zaub. Cov tswv yim ntawm cov duab digital ammeter yog ntsuas qhov voltage poob ntawm shunt lossis transformer thiab hloov mus rau tam sim no. Yog hais tias qhov voltage yog ntsuas, tsuas yog tshem tawm lub shunt los yog transformer, thiab siv qhov tsim nyog voltage faib resistor los txiav txim qhov ntau.
1. Ntau qhov kev faib tawm ntawm ammeters:
Raws li daim ntawv teeb liab, nws muab faib ua: ammeter, voltmeter, zaus ntsuas, ntsuas kub, ntsuas hluav taws xob ...
Raws li qhov yuav tsum tau ntsuas: ib-point meter, multi-point meter
Muab faib los ntawm kev ua haujlwm: cov khoom siv yooj yim, cov lus ceeb toom, cov lus sib kis, cov lus sib txuas lus, cov lus teev cov ntaub ntawv, cov lus muaj ntau txoj haujlwm, thiab lwm yam, kom tau raws li cov neeg siv khoom sib txawv.
2. Daim ntawv thov Scope:
Kev tswj cov tshuab, kev tswj xyuas hluav taws xob, lub tshuab hluav taws xob substation automation, tis network automation, lub tsev automation, industrial automation, zej zog saib xyuas, lub tsev ntse, hloov cov txee, thiab lwm yam.
