A isixhobo sokulinganisa umthamo bebhetri. Yeendlela eziphambili

Wonke umnini imoto ngopfu oko kuyimfuneko isixhobo sokulinganisa umthamo kwebhetri. Ukulinganisa eli xabiso udla kuqhutywa ngexesha indlela yolondolozo olucwangcisiweyo, kodwa kuya kuba luncedo ukwazi ukuba ukuchaza njani.

A isixhobo sokulinganisa amandla ebhetri

Ibhetri umthamo - i parameter ukuthi ichaza umlinganiselo wamandla kusiwa yi ibhetri kwi ukungaqondani ethile ngeyure enye. Oku kulinganiswa kwi A / h (iyure Ampere), kwaye ixhomekeke lexinene i electrolyte, leyo ixhomekeke isixhobo okhethekileyo - hydrometer. Xa uthenga ibhetri entsha, bonke technical parameters yeengongoma umenzi emzimbeni. Kodwa eli xabiso inokuchazwa ngokwakho. Kukho izixhobo ezikhethekileyo kunye nobuchule.

Eyona ndlela ilula - kukuba ukuthatha umvavanyi okhethekileyo, ezifana "pendant". It is a isixhobo mihla sokulinganisa capacitance ze battery imoto, ngokunjalo ombane wayo. Kulo mzekelo, uya kuchitha imali ubuncinane ixesha ufumane yoko ethembekileyo. Ukujonga, kufuneka ukuqhagamshela ifowuni iiterminal ze battery kwaye imizuzwana embalwa njengoko imisela kuphela ubuchule kunye ombane ibhetri kunye ubume amacwecwe. Nangona kunjalo, kukho ezinye iindlela yokujonga amandla bebhetri.

Indlela lokuqala (classical)

Umzekelo, imitha ingasetyenziswa njengesixhobo yokulinganisa umthamo ibhetri isithuthi, kodwa ngoncedo i ukufunda echanekileyo ufumana. Eyona nto ifunekayo kule ndlela (ebizwa ngokuba obhobhozayo indlela yokulawula) siziindleko ibhetri ngokupheleleyo. Okokuqala, kufuneka ukudibanisa kwi ibhetri enamandla abathengi (kakhulu ezifanelekileyo eqhelekileyo isibane amandla 60W).

Emva kuyimfuneko ukuba kuqokelelwe umxokelelwane, nto leyo iquka umthwalo multimeter, ibhetri, umsebenzisi kunye ifayile. Xa ibhalbhu ayitshintshi lokukhanya yayo kwimizuzu emi-2 (kungenjalo ibhetri Awunakugcinwa kwakhona!), Susa readings ngokwamakhefu ngexesha elithile. Yakuba i index iwela ngaphantsi ombane ibhanile ibhetri (oko phantsi 12B umthwalo), luvelisa iqala. Ke kaloku, esazi ixesha ukuba wathabatha ukugqibezela lo monakalo yokugcina amandla kunye nomthwalo kwabathengi ngoku, kuyimfuneko ukuba phinda yala maxabiso. Lwemveliso yala ezahlukeneyo na umthamo yokwenene ibhetri. Ukuba amaxabiso ifunyenwe ezahlukileyo data yokundwendwela kwi ecaleni ezincinci, ibhetri kufuneka itshintshwe. Le ndlela yenza kube lula ukuba ngaba kunako na ibhetri. Engxakini le ndlela kuthatha ixesha elide.

Indlela yesibini

Unako ukusebenzisa indlela apho ibhetri lukhutshwa a resistor ngokusebenzisa isekethe okhethekileyo. Ukusebenzisa istopwatshi elona xesha athathiweyo ukuze ifeze. Ekubeni amandla elahlekile kwindawo ombane phakathi 1 volt, singakwazi ngokulula amisele amandla yangoku usebenzisa ifomula mna = iUre, apho mna - ngamandla ngoku, U - ombane, R - ukuxhathisa. Kuyimfuneko ukuba ukuphepha khulula ephelele ibhetri, esebenzisa, umzekelo, irileyi okhethekileyo.

Indlela yokwenza idivayisi yakho

Xa kungekho ithuba ukuthenga isixhobo lilungile, ungasoloko kusithatha isixhobo sokulinganisa umthamo ibhetri ngesandla.

Ukuze ubone imeko isigxina kunye nomthamo ibhetri, ungasebenzisa ekulayisheni yokwela. Kuba sale ezininzi imifuziselo iiplagi esele zenziwe, kodwa unako kuqokelela oko ngokobuqu. Okulandelayo siqwalasela njengenye yeenketho.

Le modeli isebenzisa uluhlu elide, ukufezekisa umlinganiselo accuracy eliphezulu. Kukho ukuxhathisa umthwalo eyakhelwe-ngaphakathi. Isikali yahlulwe parameter (0-10 kwaye 10-15 V), nto leyo inika ukuncitshiswa eyongezelelweyo isiphoso womlinganiselo. Izixhobo kwakhona unalo isikali 3 volt-kunye nezinye ukuphela kwe isixhobo sokulinganisa ngokuvumela ekutshekisheni zeenkonkxa kwebhetri ngamnye. Iscale 15B ifunyanwa ngokunciphisa diode kunye ombane Zener. Ubukhulu yangoku ifowuni kwandisa xa ixabiso ombane lingaphaya inqanaba yokuvulwa diode zener. Xa ombane ayilungile umsebenzi ukhuselo wokwephuka lwenziwa yi diode.

Scheme: R1- zener edlulisela efunekayo ngoku; R2 R3 - resistors, bakhethwa ukuba microammeter M3240; R4 - kugqiba ububanzi baso elimxinwa; R5 - ukuxhathisa umthwalo ibandakanyiwe tumbler SB1.

Amandla wolayisho yangoku ezimiselwe ngumthetho Ohm kaThixo. Kubalo ukungawi umthwalo.

A isixhobo sokulinganisa umthamo AA ibhetri

umthamo AA ibhetri ulinganiswa e ma / h (milliamps ngeyure nganye). Kuba kumetwa neebhetri onjalo isicelo tshaja ezizodwa ezichaza ngoku, ombane kunye nomthamo bebhetri. Umzekelo kwisixhobo eso isixhobo sokulinganisa umthamo bebhetri AccuPower IQ3, nto leyo iba unikezelo amandla uluhlu ombane ukusuka volts 100 ukuya 240. Ukulinganisa imfuneko ukufaka iibhetri kungena ifowuni, yaye zonke iparameters efunekayo iya kuboniswa.

Ukumiselwa wesingxobo ne kwitshaja

Kwakhona, umthamo unako ligqitywe kwitshaja yesiqhelo. Emva kokuba izigqibo inani ophethe yangoku (oko kubonisiwe iimpawu ifowuni), ibhetri kufuneka abekwe ngokupheleleyo kwaye ukubhaqa nexesha ligqithile. Emva phinda ezi amaxabiso amabini, sifumana umbhalo umthamo.

Okuninzi Ufundo echanekileyo zingafumaneka ngokusebenzisa enye indlela apho ufuna ibhetri ngokupheleleyo-ityala, istopwotshi, a multimeter kunye nomthengi (ungasebenzisa, ezifana layita). Dibanisa umthengi ukuba ibhetri, kwaye usebenzisa multimeter ukuqinisekisa ukusetyenziswa yangoku (ezincinane oko kukuthi, ethembeke ngakumbi iziphumo). Siphawula ixesha apho isibane, yaye umphumo uba liphindaphindwe ukuselwa yangoku.
