Iibhetri D: jikelele, iimpawu

Battery - umthombo wamandla ombane (power source) ukuba amnike amandla izixhobo ezahlukeneyo abangabancedani. Ibhetri isekelwe nayiphi phawu scheme anode-cathode yinto therebetween electrolyte. Le anode kunye cathode ezenziwe ngezinto ezahlukeneyo, loo anode - Metal (Izinki) kunye cathode - ukususela oxides ngeentlobo ezahlukeneyo zesinyithi. Ngenxa yoko, xa sokuvalwa electrolyte phakathi izibonda ezimbini ibhetri kuvela umahluko yombane ezinokwenzeka, ngamanye amazwi - ugesi. Iibhetri, ngokwendalo yazo, yiya amandla eekhemikhali. Aba vimba kwamandla, oko kukuthi, ukuba kwenzeka iinkqubo vuhlayiseki. Oku ixoxe ukuba Ibhetri ingagcwaliswa agcwalisiwe emva kokuba bubudala, kodwa ayikho. Ukuba uqala ukungakuhlawulisi ibhetri, oko zisenokuqhushumba. imithombo Secondary wamandla ombane ezi zitshajwe, iibhetri ngamanye nabanako agcwalisiwe.

D neebhethri kweentlobo ezintathu:

- Salt (Zinc-carbon) - oku ke engambi uhlobo iibhetri. Ezi iibhetri babe capacitance lincinane ngokukhawuleza abakhutshwa kumaqondo obushushu asezantsi, musa ukusebenza kakuhle imithwalo ezifuna current enkulu.

- Ngomhla isiseko zinc chloride. Ezo iibhetri saline kuyinyamezela ngcono kubushushu obuphantsi kodwa abe kukuhla isigxina.

- zealkali (ialakalin) abe inani avareji ngokuthembekileyo usebenze kumaqondo obushushu asezantsi ngokufanelekileyo, kuba umthamo isigxina eliphezulu, amathuba elisezantsi ingenzeka kunye ezikhabhathini elide.

D-uhlobo neebhetri kufuneka iinkcukacha zilandelayo:

- Weight - 143 g (ubunzima inokwahluka ngokuxhomekeke kuhlobo iibhetri, iibhetri obrak kufuneka ubunzima aphezulu);

- ukuphakama - 61,3 mm;

- ubukhulu - 33.2 mm;

- ombane - 1.5 V (y ibhetri 1.2 V);

- umthamo ngoku ixhomekeka kwifomu (ityuwa, ngokusekelwe zinc chloride, kwealkali) kunye umvelisi.

I Parameter engundoqo umthamo nayiphi ibhetri. Battery Uhlobo D, ngokungafaniyo nezinye iintlobo ibhetri (uhlobo AAA, uhlobo AA, uhlobo C, njl), Ingaba ixabiso eliphezulu le parameter. Umthamo Ibhetri kunefuthe elingqalileyo ubomi bebhetri. Ngoko ke, olu khetho okuchaziweyo ampere / iiyure, oko kukuthi, zingaphi amperes ibhetri nako ukunika iyure enye yomsebenzi. Umzekelo, ukuba D-uhlobo ibhetri ngaba inobunzima ka-1300 ma / h (13 A / h), ngoko ke unako ukunika amperes-13 ngeyure enye msebenzi. Ibhetri Uhlobo D elinemibala ialakalin (ialakalin) kufuneka umthamo omkhulu, kodwa kule meko ukuba iibhetri kbavelisi ahlukeneyo ziya kwahluka. Umthamo neebhetri aphezulu semvelo "Duracell", "Varta", "GP", "Energizer". Ngenxa yoko, iibhetri D "Duracell" banekhono 18000 Ma (18A / h), "Energizer" - 17000mA (17a / h), "GP" - 13000 Ma / h (13A / h). Nangona kunjalo, olu hlobo iibhetri ibe nenani lezikolo zikhona, malunga $ 3-4 zangaphantsi ngambini.

ubomi bebhetri kuxhomekeke indlela amandla kakhulu ifowuni liyadla / isixhobo apho zifakiwe, ubude ukusebenza kwayo, kwakunye lobushushu voice.

Buyisela i neebhetri kumelwe ukuba kulungile, akavumelekanga ukuba ukusebenzisa zombini neebhetri ezindala entsha, ayikhuthazwa ukuxuba iintlobo ezahlukeneyo iibhetri (ityuwa, kwealkali). ngenxa konke oku kuyanceda kuwaphungula amandla ebhetri kwaye ubangela depressurization ukuba kungabangela umonakalo kwesixhobo / isixhobo.
