Uma ibhethri elisha eligcwalisekayo lihlanganiswa libe ibhulokhi yochungechunge, ngokuvamile lishajwa ngokuya ngamandla amanje omthamo ojwayelekile ongu-0.1c, bese liyibeka izikhathi ezimbalwa. Kodwa-ke, empeleni, kungakhathaliseki ukuthi ishaja ezenzakalelayo ithuthuke kangakanani, kuzoba khona into engavamile kumabhethri ngamanye ngemva kwesikhathi esithile, okungukuthi, i-voltage yebhethri ngayinye ephaketheni lebhethri izoba phansi kakhulu (cishe ku-volts zero), ngisho ne-Battery Phenomenon ye-voltage polarity inversion.

Ngokuhamba kwesikhathi, leli bhethri ngeke lingasebenzi, futhi ekugcineni libangele ukuthi amanye amabhethri kuphakethe lebhethri alimaze into engenhla. Isizathu siwukuthi kubalulekile ukuthi ukumelana kwangaphakathi kwalawa mabhethri akuhambisani, futhi kuzoba namazinga ahlukene okukhokhiswa ngokweqile ngesikhathi sokusetshenziswa, okwenza ibhethri elikhuphula ukumelana kwangaphakathi ukulimala kokuqala. Isibalo esingezansi sibonisa inqubo evamile yokukhipha (okungukuthi, ibhulokhi yebhethri ihambisana kakhulu futhi iphansi kakhulu kunokumelana nomthwalo), futhi iphakethe lebhethri lenziwe ngamabhethri amane avela ku-A, B, C, no-D.

Isiqondiso samanje sokuphuma sinjengoba kuboniswe esithombeni. Phakathi nenqubo yokukhipha, kucatshangwa ukuthi ukumelana kwangaphakathi kwebhethri B kuyanda, kudlula ngisho nokumelana nomthwalo R, futhi into eboniswe esithombeni, okungukuthi, A, D, no-C amabhethri amathathu ebhethri B, isikhathi eside. I-polarity yebhethri engu-B izobuyiselwa emuva futhi yonakaliswe.

Lapho umbhali enza isilinganiso sebhethri eliboniswe ku-Fig. 1, umbhali utholwa ukuthi i-voltage yebhethri ngayinye eyodwa ayihambisani kakhulu phakathi nenqubo yokukhipha, futhi kuyohlala kukhona ibhethri elisheshiswayo kuqala, futhi ekugcineni lisuke ku-zero Inegative value (okungukuthi, ukuhlehla). Uma ushintsha ibhethri elisha, ngenxa yokumelana kwangaphakathi, kuzokwandisa ukuphindaphinda kwento engenhla, ilethe inkinga yethu engapheli ngesikhathi sokusetshenziswa.

Inhlanganisela yamabhethri aphinde ashajwe ifinyeza iphuzu lokuzizwisa okufanelekile, kumavidiyo abashisekeli be-elekthronikhi. 1. Uma usebenzisa ibhethri elihlanganisiwe, kufanele uvamise ukubona i-voltage yebhethri elilodwa.

Uma uthola ukuthi ibhethri eliphansi kufanele likhishwe ngesikhathi, licutshungulwe ngokuhlukana. 2. Gada i-voltage yebhethri ngayinye nganoma yisiphi isikhathi lapho ukushajwa kushajwa.

3. Ephaketheni lebhethri, okuhamba phambili konke okuhle kakhulu kuphathwa ngokuhlukana: (1) Ukukhipha okuhlukile: sebenzisa i-electron engu-1.5V noma 5 ~ 20Ω ukumelana nomthamo wokukhipha, futhi umise kancane i-voltage ngu-0.

I-9 ~ 1Y, iningi Ibhethri izobuyela cishe ku-1.2V ngemva kokumisa ukukhipha, ukuphinda izikhathi eziningi, kuze kube yilapho ukusetshenziswa kwegiya le-multimeter 500mA isifunda esifushane samanje, ikhwalithi enhle noma ukukhishwa, ukuthukwa, inaliti, endaweni ethile (efana no-200 ~ 500mA) ) Unganyakazi ikhwalithi ende noma uphonsa ama-disharps ayishumi ngokushesha. uziro. Ngokuvamile, lapho iphoyinti lishesha ukuya kumashumi amamilimitha, ibhethri lifakwa kakhulu, futhi lingamiswa.

(2) Ukushaja okuhlukile: Ibhethri elinomehluko omkhulu wokumelana kwangaphakathi alikwazi ukuhlanganiswa ochungechungeni ukuze lishaje, ukwenza ukuzimela okukodwa, njengokushaja okuhlanganisiwe okungahlangani, ibhethri ngalinye alinele, liyingozi kakhulu, kuzoba khona amabhethri okumelana nangaphakathi angawodwana Izolimazwa ngokushajwa ngokweqile noma isiqandisi. Njengoba kuboniswe esithombeni esingenhla, sisenayo ibhethri ye-B yokumelana kwangaphakathi kwe-Tb, futhi njengoba uchungechunge lwesekethe lwamanje lulingana, kusobala ukuthi ukwehla kwe-voltage ye-TB kuphakeme kunamanye amabhethri, ngakho-ke amandla asetshenziswa ku-TB nawo amakhulu, futhi ukumelana kwangaphakathi kukhulu ngokuqhathaniswa. Ukusetshenziswa kwamandla kukhudlwana, ibhethri elingu-B lizolimala elokuqala, futhi amanye amabhethri awagcwali ngempela.

Ukuze ukhokhise ikhwalithi nokumelana kwangaphakathi kwebhethri, umbhali uklame isifunda sokushaja esilula, uma ufuna ukuthola. Ngoba ibhethri selikhishiwe, inqobo nje uma icindezelwa yi-0.LC yamanje amahora angu-10.

Kulo mfanekiso ongenhla, i-RL, i-RN ingu-5 Ω, 20 Ω / 1W, ngokulandelana, i-RM iwukumelana okuguquguqukayo kwe-5 Ω ~ 20 μlw; I-VDF iyi-diode ekhipha ukukhanya, engasetshenziswa ukukhombisa isimo sokushaja, futhi i-VD iyi-proversion diode, evimbela ibhethri. Ukulungisa i-RM kungalawula okwamanje phakathi kuka-30 kuya ku-1000, ngokuvamile amabhethri angu-5 angalungiswa abe ngu-50 kuya ku-70 mA. Uma i-trickle ishajwa, ingalungiswa ibe ngu-20 mA noma ngaphansi, futhi ububanzi bokulungisa obungenhla abushintshiwe, kanye ne-RL ku-Fig.

4 ingashintshwa ngokufanele. Inani noma inani le-voltage yokunikezela nge-SV. 4.

Ngemva kokushaja, i-voltage yebhethri eyodwa ngokuvamile iba ngu-1.35 ~ 1.45V.

Ngemva kokubeka, izinzile ku-1.25 kuya ku-1.3V.

Ngemuva kokukhishwa okuncane, kufanele kube ngu-1.25V isikhathi eside. Usanda kushajwa ngokuphelele ibhethri elilodwa nge-multimeter (5a) Hlola umjikelezo omfushane wamanje, ikhwalithi ingase izinze ku-3 ~ 5A (bheka ibhethri), futhi isikhombisi singamaminithi ukusuka kwinani lamaminithi, ikhwalithi ayizinzile ku-2A, uma unamabhethri amaningi, Khetha ibhethri eliseduze kakhulu nenhlanganisela yamabhethri.

5. Mayelana nebhethri le-nickel-cadmium, ngokuvamile alikhishwa ngokuqondile ngaphandle kokukhishwa, kodwa uma ucabangela ukuthi umthamo wokushaja awumuhle, kungcono ukushaja ishaji kagesi esele.
