I-polarity yebhethri iqondile noma ihlehla
Uma kungokokuqala ngqa ukuthenga ibhethri lemoto yakho, ungase udidwe umbuzo womthengisi mayelana ne-polarity yebhethri. Iyini i-polarity noma kunjalo? Ungakuchaza kanjani? Kwenzekani uma uthenga ibhethri eline-polarity engalungile? Sizozama ukuphendula le mibuzo esihlokweni sethu sanamuhla sengosi yeVodi.su.
Dlulisela phambili futhi uhlehlise i-polarity yebhethri
Njengoba wazi, ibhethri ifakwe esihlalweni sayo esichazwe ngokuqinile ngaphansi kwe-hood, ebizwa nangokuthi isidleke. Engxenyeni engenhla yebhethri kukhona amatheminali amabili amanje - okuhle nokubi, ucingo oluhambisanayo luxhunywe ngamunye wabo. Ukuze abashayeli bezimoto bangahlanganisi amatheminali ngephutha, ubude bocingo bukuvumela ukuthi ufinyelele kuphela kutheminali yamanje ehambisanayo ebhethrini. Ngaphezu kwalokho, i-terminal eqondile inkulu kune-negative, lokhu kungabonakala ngisho nangeso, ngokulandelana, cishe akunakwenzeka ukwenza iphutha lapho uxhuma ibhethri.
Ngakho, i-polarity ingenye yezici zebhethri, ekhombisa indawo yama-electrode aphethe manje. Kunezinhlobo eziningana zayo, kodwa ezimbili kuphela zazo ezisetshenziswa kakhulu:
- ngqo, "Russian", "inhlanganisela kwesokunxele";
- reverse "European", "right plus".
Okungukuthi, amabhethri ane-polarity eqondile asetshenziswa kakhulu emishinini eyenziwe ekhaya eyakhiwe eRussia. Ezimotweni zakwamanye amazwe, zithenga amabhethri ane-reverse euro polarity.
Unganquma kanjani i-polarity yebhethri?
Indlela elula iwukubheka ngokucophelela isitikha esingaphambili bese wenza izimpawu:
- uma ubona uhlobo lwegama: 12V 64 Ah 590A (EN), khona-ke lokhu kuyi-polarity yaseYurophu;
- uma ingekho i-EN kubakaki, khona-ke sibhekene nebhethri elivamile elinokuhlanganiswa kwesokunxele.
Kuyaphawuleka ukuthi i-polarity ivame ukuboniswa kuphela kulawo mabhethri athengiswa eRussia nase-republic yangaphambili ye-USSR, kanti eNtshonalanga wonke amabhethri afika ne-polarity yaseYurophu, ngakho-ke ayiboniswa ngokwehlukana. Yiqiniso, e-USA efanayo, eFrance naseRussia futhi, ungabona ezimpawu ezinjengokuthi "J", "JS", "Asia", kodwa azihlangene ne-polarity, zisho lokho ngaphambili. us ibhethri elinamatheminali amancane ikakhulukazi ezimotweni zaseJapan noma zaseKorea.
Uma kungenakwenzeka ukucacisa i-polarity ngokumaka, kunenye indlela:
- sibeka ibhethri ngakithi ngehlangothi langaphambili, okungukuthi, lelo lapho isitika sikhona;
- uma itheminali eqondile ingakwesokunxele, khona-ke lokhu kuyi-polarity eqondile;
- uma plus kwesokudla - European.
Uma ukhetha ibhethri yohlobo 6ST-140 Ah nangaphezulu, khona-ke inomumo wonxande obude futhi umkhondo wamanje utholakala kolunye lwezinhlangothi zalo eziwumngcingo. Kulokhu, yijikise ngamatheminali kude nawe: “+” kwesokudla kusho i-European polarity, “+” kwesokunxele isho isiRashiya.
Hhayi-ke, uma sicabanga ukuthi ibhethri lidala futhi akunakwenzeka ukwenza noma yimaphi amamaki kulo, khona-ke ungaqonda ukuthi ikuphi ukuhlanganisa nokuthi iphi i-minus ngokulinganisa ukushuba kwamatheminali nge-caliper:
- ukujiya plus kuyoba 19,5 mm;
- susa - 17,9.
Emabhethri ase-Asia, ukushuba kwe-plus kungu-12,7 mm, kanti ukukhishwa kungu-11,1 mm.
Kungenzeka yini ukufaka amabhethri ane-polarity ehlukile?
Impendulo yalo mbuzo ilula - ungakwazi. Kodwa izintambo kufanele zixhunywe ngendlela efanele. Ngokuhlangenwe nakho kwethu, ake sithi ezimotweni eziningi esike sabhekana nazo, ucingo oluhle lwanele ngaphandle kwezinkinga. Okungalungile kuyodingeka kwandiswe. Ukuze wenze lokhu, kuzodingeka ukuthi ususe i-insulation futhi unamathisele ucezu olwengeziwe locingo usebenzisa i-terminal.
Ezimotweni eziningi zanamuhla, cishe akukho ndawo yamahhala ngaphansi kwe-hood, ngakho-ke kungase kube nezinkinga ngokwakhiwa kocingo, ngeke kube khona indawo yokuyibeka. Kulokhu, ibhethri elisha elingenawo umonakalo lingabuyiselwa esitolo phakathi kwezinsuku eziyi-14. Well, noma nomuntu ukushintsha.
Uma uhlanganisa amatheminali lapho uxhuma
Imiphumela ingaba ehluke kakhulu. Umphumela olula ukuthi amafuse avikela inethiwekhi esebhodini kumasekethe amafushane azovunguza. Okubi kakhulu umlilo ozokwenzeka ngenxa yokuncibilika kwe-wire braid kanye nenhlansi. Kuyaphawuleka ukuthi ukuze umlilo uqale, ibhethri kufanele libe sesimweni esingalungile sokuxhuma isikhathi eside.
"I-Battery polarity reversal" yinto ethakazelisayo, ngenxa yokuthi akukho lutho olungasongela imoto yakho, izigxobo zebhethri zizoshintsha izindawo uma zixhunywe ngokungalungile. Nokho, lokhu kudinga ukuthi ibhethri libe yintsha noma okungenani libe sesimweni esihle. Noma kunjalo, ukuguqulwa kwe-polarity kuyingozi ebhethri ngokwayo, njengoba amapuleti azodilika ngokushesha futhi akekho ozokwamukela leli bhethri kuwe ngaphansi kwewaranti.
Uma uqapha isimo sobuchwepheshe bemoto, uxhumano lwebhethri olungalungile lwesikhashana ngeke luholele kunoma yimiphi imiphumela eyinhlekelele, ngoba ikhompyutha, i-generator, nazo zonke ezinye izinhlelo zivikelwe ngamafuse.
Kungase kuphakame izinkinga ezingathi sína uma uhlanganisa amatheminali lapho ukhanyisa enye imoto - isifunda esifushane namafuse aqhunyiswayo, nakuzo zombili izimoto.
Iyalayisha...
