Kunzima ukucabanga ukuthi ukuphila kwethu bekuyoba kuphi ngaphandle kwamabhethri ahlangene, owaziwa yiwo wonke umuntu ngokuthi "amabhethri eminwe". Amathoyizi wezingane, ama-remotes avela kuma-TV, abadlali, amakhamera nama-flashlights abamba amandla abo kulezi zithutha ezincane. Naphezu kwezinhlobo eziningi zokuhlala, akuzona njalo ukutholakala ukuthola into efanelekayo yokudla. Lesi sihloko sizokusiza uqonde ukuhlukahluka kwebhethri.
Amabhethri wezinhlamvu AA
Nakuba wonke amabhethri omunwe ahluke ngaphandle komunye nomklamo welebuli, angahluka kakhulu ekusebenzeni. Isizathu salokhu sisezweni labo langaphakathi, noma kunalokho, ku-electrolyte. Kukhona izinhlobo ezilandelayo zamabhethri uhlobo AA:
- Usawoti . Lezi yizibhethri zomunwe ezibuthakathaka futhi ezinomphela, amandla okwanele kuphela ekusebenzeni kwamadivayisi angaphansi kwamandla (ukulawula amapaneli avela kumagcekeni omculo kanye namathelevishini, isibonelo). Eqinisweni, lolu hlobo luyisikhathi eside seluphelelwe yisikhathi, kodwa alushiyi emakethe ngenxa yentengo ekhangayo yomthengi ojwayelekile. Ngezindleko ezifanayo eziphansi, zonke izinzuzo zamabhethri emunyu usawoti, ngoba ezinye izinhlobo zisezingeni eliphezulu ngokwesikhashana sokusebenza. Zingagcinwa iminyaka engaphezu kwengu-3, emva kwalokho zikhishwe ngokuphelele.
- I-alkaline . Lezi zakhi zingahle zibhekiswe ezinkambeni ezinhle - izindleko ezingabizi futhi ukusebenza kahle kakhulu uma usebenza kwimodi yokulayisha njalo ungasebenzisa ngempumelelo ezinganeni zamathoyizi, abadlali kanye nezibani zesandla. Futhi lapha, lapho kungumbuzo wemithwalo ngaphezu kwesilinganiso, isibonelo, emakhamera, masinyane ashiye umncintiswano. Amakhethri e-alkaline angakwazi ukuqhubeka esebenza cishe izikhathi ezimbili kunomunyu (kuze kube yiminyaka engu-5).
- Lithium . Lezi yizilo zangempela emhlabeni webhethri, kalula ukubhekana nomthwalo wokuziphendulela ophezulu. Zingasetshenziswa kuma-radios, esithombeni nakumavidiyo, njll. Yiqiniso, ukuthola imithombo eyengeziwe kuyodingeka ukhokhe ngaphezulu, kepha isikhathi sokuphila kwamabhethri amantombazane e-lithium sidlula inani leminyaka emihlanu.
Umthamo webhethri wezinhlamvu
Ipharamitha eyinhloko yanoma iyiphi i-accumulator yikhono layo, okungukuthi, inani lamandla anikezwe esiteshini kulo lonke isikhathi sokukhipha. Le parameter ilinganiswa ngama-ampere-hours futhi ihluka kusuka ku-800 kuya ku-3000 mA / h.
Ukumaketha kwamabhethri wezinhlamvu
Igama elithi "umunwe", nakuba liqondakala kuwo wonke umuntu, nokho akunjalo. Ngokomgomo waseMelika, amabhethri omunwe abhalwe ngamagama amabili amakhulu A. Ngokusho kwesistimu ye-International Electrical Company, ukumaka kuhlanganisa amadijithi 03, okuchaza ubukhulu besici nezinhlamvu ezihambisana nohlobo lwe-electrolyte:
- usawoti - R03;
- I-Alkaline - LR03;
- lithium - CR03.
Amabhethri eminwe waseRashiya ayimikhiqizo eqinisekisiwe futhi ebizwa ngokusemthethweni ngokuthi "isici 316".
Ukulahlwa kwamabhethri eminwe
Namuhla, akukho mndeni ongakwenza ngaphandle kwemishini ephathekayo, futhi ukukhishwa okufanele kwamabhethri ezindala kunzima kakhulu. Isikhathi sokuchithwa kwamakhemikhali okudla okunomsoco kuthatha isikhathi eside, okwesikhathi lapho besilisa khona imvelo ngamanoni ezinsimbi ezinzima. Ngakho-ke, kubaluleke kakhulu ukuba ungaphonyi amabhethri asetshenzisiwe kudoti, kodwa ukuze uwahambise emaphoyiseni akhethekile, lapho azokwenziwa khona yonke imithetho. Ngokwenzayo, amaphuzu okwamukela amabhethri esikhaleni se-post-Soviet asebenza kuphela kwamanye amadolobha amakhulu. Emadolobheni amancane, abalandeli bezemvelo kumele bawagcine nje ngezikhathi ezingcono.
