Xa ibhetri entsha egcwalisekayo idityaniswe kwibhloko yothotho, ihlawuliswa ngokubanzi ngokwendlela yangoku yomthamo oqhelekileyo we-0.1c, kwaye uyibeke amaxesha amaninzi. Nangona kunjalo, eneneni, kungakhathaliseki ukuba itshaja ezenzekelayo esetyenzisiweyo iphuculwe kangakanani, kuya kubakho into engaqhelekanga kwibhetri nganye emva kwexesha elithile, oko kukuthi, umthamo webhetri ngamnye kwipakethi yebhetri uya kuba phantsi kakhulu (kufuphi ne-volts zero), kunye nebhetri Phenomenon ye-voltage polarity inversion.

Ngokuhamba kwexesha, le bhetri iya kusebenza ngokungenakuthintelwa, kwaye ekugqibeleni ibangele ezinye iibhetri kwipakethi yebhetri zonakalise le nto ingasentla. Isizathu kukuba kubalulekile ukuba ukuchasana kwangaphakathi kwezi bhetri akuhambelani, kwaye kuya kubakho iidigri ezihlukeneyo zokugqithiswa ngokugqithiseleyo ngexesha lokusetyenziswa, okwenza ibhetri eyonyuka ekuchaseni kwangaphakathi umonakalo wokuqala. Lo mzobo ungezantsi ubonisa inkqubo yokukhutshwa kwesiqhelo (oko kukuthi, ibhloko yebhetri iyahambelana kakhulu kwaye isezantsi kakhulu kunokumelana nomthwalo), kwaye ipakethe yebhetri yenziwe ngeebhetri ezine ukusuka ku-A, B, C, kunye no-D.

Isalathiso sangoku sokukhupha njengoko kuboniswe kumzobo. Ngethuba lenkqubo yokukhupha, kucingelwa ukuba i-B ibhetri yangaphakathi yokuchasana iyanda, ide idlule i-resistor R, kunye nesiganeko esiboniswe kumzobo, oko kukuthi, i-A, D, kunye ne-C iibhetri ezintathu kwibhetri ye-B, ixesha elide. I-polarity yebhetri ye-B iya kubuyiselwa umva kwaye yonakaliswe.

Xa umbhali enza umlinganiselo webhetri eboniswe kwiFig. I-1, umbhali ufumanisa ukuba i-voltage yebhetri enye ininzi ayihambisani ngexesha lenkqubo yokukhupha, kwaye kuya kuhlala kukho ibhetri eqala ngokukhawuleza, kwaye ekugqibeleni isuka kwi-zero Ixabiso elibi (oko kukuthi, ukubuyisela umva). Ukuba utshintshisa ibhetri entsha, ngenxa yokuchasana kwangaphakathi, kuya kwandisa ukuphindaphinda kwento engasentla, ukuzisa ingxaki yethu engapheliyo ngexesha lokusetyenziswa.

Ukudityaniswa kweebhetri ezitshajekayo kushwankathela inqaku lamava afanelekileyo, kwiividiyo zabathandi be-elektroniki. 1. Xa usebenzisa ibhetri edibeneyo, kufuneka uhlale uqaphela amandla ombane webhetri enye.

Ukuba ufumanisa ukuba ibhetri ephantsi kufuneka isuswe ngexesha, iqhutywe ngokwahlukileyo. 2. Beka iliso kumbane webhetri nganye nangaliphi na ixesha xa ukutshaja kukhutshiwe.

3. Kwipakethi yebhetri, okona kulungileyo konke kusingathwa ngokwahlukileyo: (1) Ukukhutshwa okwahlukileyo: sebenzisa i-electron ye-1.5V okanye i-5 ~ 20Ω ukuchasana okuguquguqukayo kumthwalo wokukhupha, kwaye umise i-voltage yi-0.

I-9 ~ 1Y, ininzi Ibhetri iya kubuyela malunga ne-1.2V emva kokumisa ukukhutshwa, ukuphinda amaxesha amaninzi, de kusetyenziswe i-multimeter 500mA gear i-short circuit yangoku, umgangatho omhle okanye ukukhutshwa, izithuko, inaliti, kwindawo ethile (efana ne-200 ~ 500mA) ) Musa ukuhambisa ixesha elide lomgangatho ophantsi okanye ukulahla i-discharmps ngokukhawuleza, kunye ne-dischamp ephantsi, kwaye unothi. Ngokubanzi, xa isalathisi sikhawuleza ukuya kumashumi eemilimitha, ibhetri ibekwe kakhulu, kwaye inokumiswa.

(2) Ukutshaja okwahlukileyo: Ibhetri eneeyantlukwano ezinkulu zangaphakathi zokumelana ayinakudityaniswa kuthotho ukuhlawulisa, ukwenza ukuzimela okukodwa, njengokutshaja okudityanisiweyo okudityanisiweyo, nokuba ibhetri nganye yanele, iyingozi ngakumbi, kuya kubakho iibhetri zokuxhathisa zangaphakathi Kuya konakala ngokugqithiswa okanye ifriji. Njengoko kubonisiwe kulo mzobo ungentla, sisenayo ibhetri ye-B yokumelana ne-Tb yangaphakathi, kwaye ekubeni uchungechunge lwesekethe lwangoku lulingana, kuyacaca ukuba i-voltage drop drop of TB iphezulu kunezinye iibhetri, ngoko ke amandla asetyenziswe kwi-TB nawo mkhulu, kwaye ukuchasana kwangaphakathi kukhulu. Ukusetyenziswa kwamandla amakhulu, ibhetri ye-B iya konakaliswa ngeyokuqala, kwaye ezinye iibhetri azigcwali.

Ukuze uhlawule umgangatho kunye nokuchasana kwangaphakathi kwebhetri, umbhali wayila isiphaluka esilula sokutshaja, ukuba ufuna ukufumanisa. Ngenxa yokuba ibhetri ikhutshiwe, ngoko nje ukuba icinezelwe yi-0.LC yangoku kwiiyure ze-10.

Kulo mfanekiso ungentla, i-RL, i-RN yi-5 Ω, i-20 Ω / 1W, ngokulandelanayo, i-RM yi-resistance variable ye-5 Ω ~ 20 μlw; I-VDF i-diode ekhupha ukukhanya, engasetyenziselwa ukubonisa imeko yokutshaja, kwaye i-VD i-proversion diode, ukukhusela ibhetri. Ukulungelelanisa i-RM kunokulawula okwangoku phakathi kwe-30 ukuya kwi-1000, ngokubanzi iibhetri ezi-5 zinokuhlengahlengiswa kwi-50 ukuya kwi-70 mA. Xa i-trickle ihlawuliswa, inokulungelelaniswa kwi-20 mA okanye ngaphantsi, kwaye uluhlu lohlengahlengiso olungentla alutshintshwa, kunye ne-RL kwi-Fig.

4 inokutshintshwa ngokufanelekileyo. Ixabiso okanye SV ixabiso lombane wobonelelo. 4.

Emva kokutshaja, amandla ombane ebhetri enye aqhele ukuba yi-1.35 ~ 1.45V.

Emva kokubeka, izinzile kwi-1.25 ukuya kwi-1.3V.

Emva kokukhutshwa okuncinci, kufuneka kube yi-1.25V ixesha elide. Ukutshaja nje ngokupheleleyo ibhetri enye nge-multimeter (5a) Ukuvavanya isiphaluka esifutshane sangoku, umgangatho unokuzinza kwi-3 ~ 5A (jonga ibhetri), kwaye isalathisi yimizuzu ukusuka kwinani lemizuzu, umgangatho awuzinzile kwi-2A, ukuba uneebhetri ezininzi, Khetha ibhetri esondele ngakumbi kwindibaniselwano yeebhetri.

5. Ngokuphathelele ibhetri ye-nickel-cadmium, ngokuqhelekileyo ayikhutshwa ngokuthe ngqo ngaphandle kokukhutshwa, kodwa ngokuqwalasela ukuba umthamo wokutshaja awulungile, kungcono ukubiza intlawulo yombane eseleyo.
