Isimiso somsebenzi webhethri likabhontshisi wesoya ibhethri le-asidi eholayo liwukugcina amandla kanye nedivayisi yokuguqula, lapho liphuma, ibhethri liguqulelwa ngokuqondile libe amandla kagesi; lapho ukushaja kushajwa ngqo endaweni yokugcina amandla amakhemikhali. Inqubo yokushaja nokukhipha iqedwa ukusabela kwamakhemikhali. Ifomula ye-electrochemical reaction yebhethri le-lead-acid imi kanje: Kusukela ekuphenduleni okungenhla, kungabonakala ukuthi uma ibhethri ishajwa, uma iqhubeka nokushaja, kubangwa i-electrolysis yomswakama.

Futhi umphumela wamanzi we-electrolytic uzobangela ukuthi ingxenye yebhethri ye-electrode ibe ne-oksijeni, i-electrode engalungile i-hydrogen, uma la magesi engakwazi ukuphinda ahlanganiswe, ibhethri izolahlekelwa isisindo. Ngakho-ke, kuyadingeka ukuba njalo hydration kanye nokugcinwa. Ibhethri le-lead-acid elawulwa yi-valve ayidingi ukwengeza ukugcinwa kwamanzi, ukhiye obaluleke kakhulu ukuthi ibhethri ingahlanganiswa kubhethri, kuyilapho ivimbela ukuna kwe-hydrogen.

Izizathu zokuqhuma kwebhethri Ukuxhumeka kwebhethri kukhululekile kuye ngokuthi ifomula yokubala yamandla: Q = I2RT (q imele amandla, ngimele okwamanje, ukumelana kwamamitha angu-R, i-T imele isikhathi), futhi isitoreji samandla sizokhulula inani elithile lokushisa ngesikhathi sokukhipha, ukukhipha okwamanje Uma likhulu inani lokumelana, kukhulu ukushisa okukhishwayo. Ukuxhumeka kwebhethri ukuxega kungaholela ekwenyukeni kokumelana nokuxhumana, futhi kwande ngokuhamba kwesikhathi. Uma ibhethri lisetshenziswa, i-current ingabangela ukushisa ngengxenye, inkulu ukugeleza kwamanje, ubude besikhathi, ukukhiqiza ukushisa okungaphezulu, izinga lokushisa lizoqhubeka likhuphuka.

Uma izinga lokushisa likhuphuka ngokwezinga elithile, lizobangela ukushajwa kwetheminali yebhethri kumpahla ye-casing yangaphandle, futhi i-ABS iyabhema. Ukuxhumana okubangelwa indawo yomlilo exegayo bheka uMdwebo 2. Umfanekiso 3 ijika lesikhathi lokushisa ekukhishweni okuthile okungu-4 kuhlu lwebhethri eliphezulu.

I-voltage yokumisa ibhethri yebhethri ingu-528V, iqembu ngalinye 44, ukucaciswa kwebhethri elilodwa ngu-12V100AH, kanti isikhathi sokulethwa unyaka ongu-1. Njengoba kungase kubonakale emfanekisweni, izinga lokushisa kusukela ekuqaleni kokuqala kwamandla kagesi we-39 likhuphuka ngokushesha, futhi lapho ukukhishwa kuyihora elingu-1, izinga lokushisa lisondele ku-80 ¡ã C. Ngemuva kokukhishwa, hlola, ibhethri lama-39 linenkinga exekethile.

Ngakho-ke, ukuxega koxhumano kubangela ukungajwayelekile kwebhethri, futhi kuba nobungozi bomlilo. Ukugudluka okushisayo kwebhethri eliphuma ekulawuleni ibhethri kubhekisela ekushajweni kwebhethri okungaphezu kwamandla noma izinga lokushisa elizungezile liholela kumanje ukushaja ngokweqile, futhi ukushisa okwenzekayo kuzobangela ukuthi ibhethri lifudumale nakakhulu. Ukwenyuka kwezinga lokushisa kwebhethri kungabangela ukumelana kwangaphakathi kwebhethri, futhi ukwehla kokumelana kwangaphakathi kuye kwaqinisa ukushaja kwamanje.

Ukunyuka kwezinga lokushisa nokwenyuka kwamanje, ukuze izinga lokushisa langaphakathi lebhethri lifike ku-120 ¡ã C, athambise izindlu ze-ABS (cishe ngo-90 ¡ã C kusukela endaweni yokuthambisa ye-ABS), ngaleyo ndlela kukhiqize ukunwetshwa, ukuvuza, nomlilo. Kumele kuqashelwe ukuthi ibhethri elivamile elintantayo lingase libe khona esikhathini sekwephuzile, okungukuthi ibhethri yokugcina yokushaja izokhiqiza ukusabela kwamanzi e-electrolytic, futhi ukusebenza kahle kokuhlanganiswa kwe-oksijeni akufinyeleli ku-100%, futhi ukulahlekelwa njalo kwe-electrolyte kuzoholela ekuhlukaniseni. kanye nokulahleka kwamanzi okwengeziwe, futhi ekugcineni kubangele ukungalawuleki okushisayo. Ngakho-ke, futhi kuwuhlobo lokushaja ngokwemvelo.

Uma ibhethri likhokhiswa ngokweqile, izinga lamanzi e-electrolysis yangaphakathi lizosheshisa, lawa magesi awathathwa, azohlala eqoqana, lapho ukucindezela kwangaphakathi kudlula ukuvulwa kwe-valve, i-hydrogen ikhishwa, uma i-hydrogen ixubene, uma isayithi lingcono Kulula ukuvutha uma kunenhlansi ngaphandle. Ukuvuza kwebhethri le-lead-acid ukuvuza kubhekisela ebhethrini elisebenzayo, kanye nengaphezulu lechibi lomlilo elibangelwa indawo ye-electrolyte yechibi lomlilo lesekhethi kagesi. Isizathu sokuthi kungani ukukhishwa kwebhethri kungahlukaniswa ngezigaba ezintathu: 1 ukulimala kokuvala kwesakhiwo kunqubo yokukhiqiza, njengekholomu ye-polar kanye nokushisela kwegobolondo noma ukwehluleka ukuba khona kwendawo yokunamathisela ukuze uthole ngesikhathi.

Kukhona ukuvuza okwenzeka ekusetshenzisweni; 2 ukusebenza okungalungile ngesikhathi sokuthutha noma ukufakwa, igobolondo lebhethri elibangelwe liyabuswa noma lingabonakali, futhi alikhiphi ngaphandle ngesikhathi; 3 izilungiselelo zokushaja azinangqondo, ukuze ibhethri likhokhiswe ngokweqile Ukukhula, ukucekelwa phansi kwezindlu, ukuvuza okudalwe. Impande noma ukukhokhisa ngokweqile. Umfanekiso 4 ubonisa indawo yokuvuza kwebhethri.

Sekukonke, isistimu yokumisa i-UPS kufanele ihambisane nezindinganiso ze-IEC60346 zezinhlelo zokumisa i-low-voltage. Lokhu kusho ukuthi iningi le-UPS, i-centralline namafreyimu ebhethri ephakethe lebhethri amisiwe. Ngakho-ke, uma kunebhethri kuphakethe lebhethri, i-electrolyte evuzayo igelezela kufreyimu yebhethri, iphakethe lebhethri liyafinyezwa ukuze lidale ingozi.

Ukutholwa kwamaphutha nokuvimbela iphutha elingenhla, njengoketshezi oluvuzayo lwebhethri olusobala kanye noxhumo lwebhethri kungatholwa ngokubonakala kokubuka nokuhlola okuvamile. Kodwa lapho lezi zindlela zingasakwazi ukuba nephutha, kuzothola ngokushesha ukuthi izikhathi eziningi kuzoba usuku lwengozi. Ngakho ingabe ikhona indlela yokubikezela kusukela empandeni ebangelwe noma ebambezelekile? Mayelana nomugqa wokuxhuma njalo kutholwa ukumelana nokuxhumeka kwebhethri nokushintsha kwezinga lokushisa.

Mayelana nokuphuma kokushisa okushisayo, ukuhlaziya okuvela phezulu, singafinyelela isiphetho: isizathu esibaluleke kakhulu esidala lawa maphutha ukushaja. Uma ibambezelekile noma iqeda izehlakalo zokushaja, kusho ukuthi ingabambezeleka ngempumelelo kanye nokuvela kwezingozi zokuvikela izingozi. Futhi ukuvuza kwebhethri kungahlulelwa ngokuqapha ukusebenza kokufakwa kwebhethri nokutholwa kokuvuza kwebhethri.

1 Ukuxhunywa kwebhethri Khulisa Umfanekiso 5 Ebhethrini kunedatha yokumelana kwangaphakathi yokusebenza okuvamile kweyunithi yegatsha lika-opharetha oyedwa 24. Njengoba kubonakala emfanekisweni, ukumelana kwangaphakathi kwebhethri yephakethe elilodwa kuyibanga elijwayelekile, futhi ukuvumelana kungcono, futhi ukumelana kwangaphakathi kuphakathi kuka-0.2 kuya ku-0.

3m. Ngemuva kokuthi ibhethri ithunyelwe isikhashana, uma umugqa wokuxhuma ukhululekile, kuzokwenza ukuthi ukumelana nokuxhumana kwebhethri kwande, okuzophinde kwandise inani lokuhlola lokumelana kwangaphakathi. Ukuqinisekisa ukumelana kwangaphakathi (okuhlanganisa ukumelana nokuxhumeka kwangaphakathi) kanye nobudlelwano bokuphumula bokuxhumana, la la la lans amantongomane ebhethri engu-# 21 bese uhlola ukumelana kwangaphakathi futhi, futhi imiphumela yokuhlolwa ikhonjiswe kuMfanekiso 6.

# 21 Kukhona ushintsho olukhulu ngaphambili kwebhethri ukumelana kwangaphakathi, okucacisa ubudlelwano obuqondile phakathi kokumelana kwangaphakathi (okuhlanganisa ukumelana nokuxhumeka kwangaphakathi) nokuxhuma okuxekethile. Kungabonakala ukuthi ngokuqapha ukumelana nokuxhumeka phakathi kwamabhethri nokuhlaziya idatha eqoqiwe, kungenzeka ukucacisa ukuthi ibhethri inengozi ekhululekile, ivimbela ukuvela komlilo. 2 I-thermal ephuma ekulawuleni ibhethri ephuma ekulawuleni ibhethri ibalulekile ngoba ibhethri lishajwe kakhulu futhi izinga lokushisa eliphezulu, ngakho-ke uma nje kungenzeka ukuvimbela ibhethri ukushajwa kanye nezinga lokushisa eliphezulu kungavimbela ngempumelelo ukulahlekelwa ukushisa kwebhethri.

1 Yenza ukucubungula okufanele, kungavimbela ngempumelelo ukushajwa kwebhethri; Misa ukushaja ukuze uvimbele amaphakethe ebhethri ukuthi angashajwa. Mayelana nesigcawu esintantayo, esimweni sokwehluleka kwebhethri, isistimu kufanele isethe ugesi ukuze inxephezele ibhethri ngenxa yokuzikhipha ngokwayo. Uma ibhethri selishajwe ngokugcwele, isistimu ivala ngokuzenzakalelayo ukushaja ukuze kuvinjelwe ukushajwa ngokweqile okubangelwa ukushajwa okuntantayo okuqhubekayo, ukuze iphekhi yebhethri njalo igcine isimo sayo esihle kakhulu, futhi inwebe ngempumelelo impilo yebhethri; 3.

Isistimu yokuphatha ehlakaniphile yebhethri ishajwa ngebhethri. Yenza ukuphatha okukhaliphile. Uma ibhethri iseduze nokugcwala, uma izinga lokushisa elizungezile litholwa, isistimu ihanjiswa futhi uhlelo luzongena kwimodi yokulala (akukho okwamanje ukushaja) ngokusebenzisa imodyuli yokulawula ehlakaniphile, bese izinga lokushisa kwebhethri liwela esimweni esivamile.

Qhubeka nokushaja ibhethri. Lokhu kungavimbela ngempumelelo izinga lokushisa kanye nokuphromotha okufanayo kwamanje, ngaleyo ndlela kususe ukuvela kokuphuma kwe-thermal.
