Hnub ci zog Inverter Ntshiab Sine Wave

TD series hnub ci zog inverter ntshiab sine yoj

Yog li ntawd, txhawm rau ntsuas qhov ntsuas hluav taws xob hauv Circuit Court kom raug, voltmeter yuav tsum muaj qhov ua haujlwm loj heev, txwv tsis pub nws tsis tuaj yeem tsis quav ntsej, thiab ntsuas tus nqi yuav tsis raug. Tau kawg, peb kuj tuaj yeem xav tias nws tsis yooj yim sua rau txhua qhov voltmeter tsis koom nrog. Nyob rau hauv Circuit Court, nws yog tsis yooj yim sua kom muaj tseeb kiag li, thiab tus nqi voltage ntsuas los ntawm nws yuav yeej ib txwm qis dua tus nqi tiag tiag. (Qhov no yog vim qhov kev sib txuas tsis sib xws yog ib txwm me dua qhov kev tiv thaiv nyob rau hauv ib qho kev sib txuas sib txuas, yog li tom qab kev sib txuas ua ke Cov ib nrab voltage ntawm Circuit Court yuav tsum raug txo.

Tau kawg, lwm lub ntsiab lus uas yuav tsum tau xav txog yog qhov loj dua qhov ntau ntawm cov voltmeter, qhov zoo dua, vim tias ib txwm muaj qhov sib txawv ntawm tib neeg kev nyeem ntawv. Qhov loj dua qhov ntau, qhov ntau dua qhov sib txawv ntawm qhov kev nyeem ntawv. Ntev npaum li nws tsim nyog rau A voltmeter nrog ntau yam yog qhov zoo.

Voltage transformers yuav muab faib ua ob hom: electromagnetic hom thiab capacitive voltage divider hom. Thaum qhov hluav taws xob theem yog 220kV thiab qis dua, feem ntau ntawm lawv yog hom electromagnetic, yog li hom electromagnetic tau qhia.

Muaj ob hom voltage transformers: ib-theem thiab peb-theem, thiab peb-theem voltage transformers feem ntau tsuas muaj ib theem voltage hauv qab no 20kV.
