Indlela yokuvavanya iibhetri zenqwelo yegalufa nge-voltmeter?

Ukuvavanya iibhetri zenqwelo yegalufa nge-voltmeter yindlela elula yokujonga impilo yabo kunye nenqanaba lentlawulo. Nali inyathelo ngenyathelo isikhokelo:

Izixhobo ezifunekayo:

• Digital voltmeter (okanye multimeter iseti yombane DC)

• Iiglavu zokhuseleko kunye neeglasi (ukhetho kodwa luyacetyiswa)

Amanyathelo okuvavanya iibhetri zeNqwelo yeGalufa:

1. Ukhuseleko kuqala:

• Qinisekisa ukuba inqwelo yegalufa icinyiwe.

• Ukuba ujonga iibhetri nganye, susa naziphi na izacholo zentsimbi kwaye ugweme ukunqumla iitheminali.

2. Misela umbane webhetri:

• Ibhetri ye-6V (ixhaphakile kwiinqwelo ezindala)

• Ibhetri ye-8V (ixhaphakile kwiinqwelo ezingama-36V)

• Ibhetri ye-12V (ixhaphakile kwiinqwelo ze-48V)

3. Jonga iibhetri zomntu ngamnye:

• Cwangcisa voltmeter ukuba DC Volts (20V okanye uluhlu oluphezulu).

• Chukumisa iprobe:

  • Uphononongo olubomvu (+) ukuya kwitheminali elungileyo.

  • Uphononongo olumnyama (–) ukuya kwitheminali ethabathayo.

• Funda amandla ombane:

  • 6V ibhetri:

    • Ichajiwe ngokupheleleyo: ~ 6.3V–6.4V

    • I-50% ihlawuliswe: ~ 6.0V

    • Ikhutshiwe: Ngaphantsi kwe-5.8V

  • 8V ibhetri:

    • Ichajiwe ngokupheleleyo: ~ 8.4V–8.5V

    • I-50% ihlawuliswe: ~ 8.0V

    • Ikhutshiwe: Ngaphantsi kwe-7.8V

  • 12V ibhetri:

    • Ichajiwe ngokupheleleyo: ~ 12.7V–12.8V

    • I-50% ihlawuliswe: ~ 12.2V

    • Ikhutshiwe: Ngaphantsi kwe-12.0V

4. Qwalasela iPakethi iyonke (iTotal Voltage):

• Qhagamshela i-voltmeter kwi-positive engundoqo (ibhetri yokuqala +) kunye ne-negative engundoqo (yebhetri yokugqibela –).

• Thelekisa amandla ombane alindelekileyo:

  • Inkqubo ye-36V (iibhetri ze-6V ezintandathu):

    • Ichajiwe ngokupheleleyo: ~38.2V

    • I-50% ihlawuliswe: ~ 36.3V

  • Inkqubo ye-48V (iibhetri ze-8V ezintandathu okanye iibhetri ezine ze-12V):

    • Ichajiwe ngokupheleleyo (amalulwane e-8V): ~50.9V–51.2V

    • Icharge ngokupheleleyo (12V amalulwane): ~50.8V–51.0V

5. Uvavanyo lomthwalo (Ngokuzikhethela kodwa kuyacetyiswa):

• Qhuba inqwelo imizuzu embalwa kwaye ujonge kwakhona amandla ombane.

• Ukuba amandla ombane ehla kakhulu phantsi komthwalo, ibhetri enye okanye ngaphezulu inokuba buthathaka.

6. Thelekisa zonke iibhetri:

• Ukuba ibhetri enye yi-0.5V–1V ngaphantsi kunezinye, isenokusilela.

Uzitshintsha nini iibhetri:

• Ukuba naliphi na ibhetri lingaphantsi kwe-50% yentlawulo emva kwentlawulo epheleleyo.

• Ukuba i-voltage yehla ngokukhawuleza phantsi komthwalo.

• Ukuba ibhetri enye ihlala ingaphantsi kunezinye.
