Ibhethri - inqolobane yamandla
Ibhethri iwumthombo kagesi emotweni. Lokhu kwenza kube nokwenzeka ukuqoqa ngokuphindaphindiwe nokuletha impahla.
Ezimotweni zesimanje, ibhethri ifaniswe ngokunembile nohlobo namandla enjini evuthayo yangaphakathi, amandla okukhanyisa nezinye izinto ezisebhodini.
Ibhethri lesiqalisi isethi yezinto ezixhunywe ngogesi zavalwa kumaseli ahlukene abekwe ngaphakathi kwekesi lepulasitiki. Ikhava inamatheminali nama-inlets avaliwe ngamapulaki ahlinzeka ngokunakekelwa nokuphuma kwamagesi akhishelwa kuseli.
Amakilasi ebhethri
Amabhethri akhiqizwa ngamakilasi amaningana, ahluke ngobuchwepheshe bokukhiqiza, izinto ezisetshenziswayo kanye nentengo. Ibanga elijwayelekile le-lead-antimony linikeza ikhwalithi egculisayo ngentengo ethengekayo. Isigaba esiphakathi sifinyelela phezulu. Umehluko ulele esakhiweni sangaphakathi kanye nemingcele engcono kakhulu. Amabhethri eza kuqala 
amapuleti awo enziwe ngama-alloys e-lead-calcium. Zifinyelela kumapharamitha aphezulu futhi azidingi ukulungiswa. Lokhu kusho ukuthi ukusetshenziswa kwamanzi kwehle ngamaphesenti angama-80 uma kuqhathaniswa namabhethri ajwayelekile. Amabhethri anjalo ajwayele ukuhlonyiswa ngamasistimu alandelayo: ukuvikela ukuqhuma, ukuvikela ukuvuza kanye nenkomba yokushaja optical.
nemingcele
Elinye lamanani abaluleke kakhulu afaka uphawu lwebhethri umthamo walo omncane. Lokhu ukushajwa kukagesi, kukalwa ngama-amp-amahora, ibhethri engayinikeza ngaphansi kwezimo ezithile. Umthamo olinganiselwe webhethri elisha elishajwe kahle. Ngesikhathi sokusebenza, ngenxa yokungabuyiseleki emuva kwezinye izinqubo, ilahlekelwa amandla okuqongelela inkokhiso. Ibhethri elilahlekelwe uhhafu womthamo walo kufanele lishintshwe.
Isici sesibili esibalulekile ivolumu yokulanda. Ivezwa ekukhishweni kwamanje okucaciswe ngumkhiqizi, ibhethri elingakwazi ukukuletha ku-minus 18 degrees kumasekhondi angu-60 kuze kufike ku-voltage engu-8,4 V. Ukuqala okuphezulu kwamanje kuyaziswa ikakhulukazi ebusika, lapho isiqalisi sidonsa i-current engaba ngu-200. -300 V. 55 ama-ampere. Inani lamanje lokuqala lingalinganiswa ngokwezinga le-DIN yaseJalimane noma izinga le-SAE laseMelika. Lawa mazinga ahlinzeka ngezimo ezihlukene zokulinganisa, isibonelo, ibhethri elinomthamo ongu-266 Ah, imanje eliqalayo ngokwe-DIN lingu-423 A, futhi ngokwezinga laseMelika, lifinyelela ku-XNUMX A.
Umonakalo
Isizathu esivame kakhulu sokulimala kwebhethri ukuvuza kwenqwaba esebenzayo kusuka kumapuleti. Izibonakalisa njenge-electrolyte enamafu, ezimweni ezimbi kakhulu iphenduka ibe mnyama. Izizathu zalesi simo zingase zibe ukushaja ibhethri ngokweqile, okubangela ukwakheka kwegesi ngokweqile kanye nokwanda kwezinga lokushisa le-electrolyte futhi, ngenxa yalokho, ukulahlekelwa kwezinhlayiya eziningi ezivela kumapuleti. Isizathu sesibili ukuthi ibhethri ifile. Ukusetshenziswa njalo kwe-inrush current ephezulu nakho kuholela emonakalweni ongenakulungiseka kumapuleti.
Kungacatshangwa ukuthi ebusika ibhethri ilahlekelwa cishe amaphesenti angu-1 omthamo wayo kanye ne-inrush current ngaphambi kokwehla kwezinga lokushisa kwe-1 degree C. Ngakho ebusika ibhethri ingaba ngamaphesenti angu-50 "ibuthakathaka kunasehlobo" ngenxa yokuhluka kwezinga lokushisa. Abakhiqizi bamabhethri okuhola babonisa ukuqina kwalawa madivaysi emisebenzini eyi-6-7, okuyinto ekusebenzeni ihumusha iminyaka engu-4 yokusebenza. Kuyafaneleka ukwazi ukuthi uma ushiya imoto ifakwe ibhethri elisebenza ngokugcwele amandla amahora 45 ampere izibani eziseceleni, kuzothatha amahora angu-27 ukukhipha ngokugcwele, uma ugongolo ongaphakeme, khona-ke ukukhishwa kuyokwenzeka. ngemva kwamahora angu-5, futhi lapho sivula iqembu lezigebengu eziphuthumayo, ukukhishwa kuzohlala kuphela ngo-4,5, XNUMX ezimpondweni.
Ngemoto, kufanele uthenge ibhethri elinamapharamitha kagesi afanayo, umumo nobukhulu, kanye nosayizi ohambisanayo wamatheminali wezigxobo njengowokuqala. Sicela uqaphele ukuthi abakhiqizi bebhethri bayakwenqabela ukungezwa koketshezi olucupha uketshezi ku-electrolyte.
