AAA Amabhethri: izinhlobo kanye nezici

Ubuchwepheshe ezakha kakhulu ezweni lanamuhla bavame ukunciphisa kanye nokuntuleka izintambo. Lokhu kuholela yokuthi eminyakeni yamuva abaningi kukhona ezihlukahlukene Amadivayisi nemishini for ukudla asebenzisa "AAA" uhlobo amabhethri. Amadivayisi anjalo ayaleze ukuba leyo ndlu cishe yilowo nalowo phakathi kwethu. Lokhu igundane engenawaya, imishini ukushefa, elawulwa kude TV and DVD, oluphathwayo abalobi izwi, abadlali umsindo, njll

Amabhethri "AAA" ngenxa yobukhulu balo encane uvame ukubizwa ngokuthi 'mizinchikovymi "noma" minipalchikovymi ". notation elandelayo lungasetshenziswa for kophawu ukudla izinto zalolu hlobo: LR3, u-R3, LR03 (IEC) R03. Uma ukhetha iseli yegajethi yakho kumelwe sizinake nohlobo electrolyte esetshenziswa, ngoba kuthinta umthamo, ubude lomsebenzi kanye nekhono ashona.

Kuye ukubunjwa yayo, "AAA" amabhethri zihlukaniswe nosawoti evamile, ane-alikhali (ane-alikhali) kanye lithium.

Amandla kagesi, izinto lapho usawoti electrolyte isetshenziswa, eyenzelwe umthwalo ongaphakeme futhi ngokuvamile okusetshenziswa amawashi, thermometer electronic, futhi elawulwa kude. Ziyakwazi eshibhe futhi ibingaba eyesikhashana ngempela. Ukuze uwahlukanise kwezinye izinhlobo ukungabi okungenzeka L Isiqalo ukuba kophawu, isb R3, isamba esingu-R6, futhi izindleko ongaphakeme (njengoba kushiwo ngenhla).

Alkali (ane-alikhali) amabhethri "AAA" hlala isikhundla Lesisemkhatsini. I electrolyte basebenzisa potassium hydroxide, futhi lokhu umehluko oyinhloko kusukela izakhi nosawoti. Ukusabela Chemical zenzeka emithonjeni efana ngejubane elikhulu. Lokhu kunengxenye ekwenzeni kangcono ukubuya zamanje. Bakhonza eside futhi efanelekayo imishini ezingeni isilinganiso energy ukusetshenziswa: abadlali umsindo, PDA, imisakazo, njll Ngokungafani nezinye izinhlobo kubo kungaba izwi «ane-alikhali» futhi ukuba khona L ncwadi kophawu.

Imihlobo best of lithium amabhethri "AAA" uhlobo. Sinenkosi okungenani ukumelana kwangaphakathi futhi isikhathi eside ngangokunokwenzeka ukuphila service. Ziyakwazi inenzuzo amadivayisi nge olunzulu energy ukusetshenziswa: amathoyizi, izibani LED, njll

Uma idivayisi isetshenziswa njalo ngokwanele, bese enhle kakhulu okunye "minipalchikovym" ane-alikhali futhi lithium amaseli abe amabhethri elishajekayo "AAA" uhlobo. Nge ishaja emithonjeni efana inqe ngokwesilinganiso engaba yinkulungwane izikhathi. Umthamo Ibhethri elishajekayo ngokuvamile kukhonjisiwe ampere-amahora. Ukubhebhetheka manje wathola lezi zinhlobo ezilandelayo izakhi:

• Li-pol (Li-polymer);
• Li-pol (Li-ion);
• NiMH (Nickel Metal hydride);
• NiCd (nickel-cadmium).

Ngamunye wabo has izici zayo siqu. Ngakho, NiMH-amabhethri kakhulu sensitive abantu imali eningi, futhi umsebenzi lithium futhi kuncike voltage lokushisa. Imithombo uhlobo NiMH futhi NiCd ifa okuthiwa "inkumbulo ukusebenza", okuyinto ukunciphisa capacitance lapho ukushaja ibhethri hhayi kukhishelwa ngokugcwele. Ngaphezu kwalezi zinhlobo ezimbili libhekene appreciable self uze uphele du, isb icala ukulahlekelwa ngisho nalapho ingenzi lutho, uma idivayisi ivaliwe. Cadmium amabhethri ngisho babe low power ukusetshenziswa, ezinhle ukumelana yesithwathwa futhi zingamelana ngisho izifunda okufutshane.

Ngakho-ke, ukukhethwa umthombo wamandla "AAA" uhlobo engaphansi ngokuphelele phezu idivayisi lapho lizosetshenziswa nemibandela umsebenzi esikhathini esizayo. Nse efanayo lapho uthenga into udinga ukuba banake sha futhi eshalofini yokuphila.
