I-terminal ye-corrosion yebhetri yahlulwe ibe yikhemikhali ye-corrosion. Kuphela nje kukuba i-asidi yokubola; kukho ukubola kwe-electrochemical, ngenxa yokumahluko kumahluko onokuthi ubekho ngenxa yezixhobo zoqhagamshelwano zekholamu. Umdibaniso webhetri udliwe, umhlwa, kunye nokungcola, kuya kwandisa ukuchasana noqhagamshelwano, okukhokelela kubunzima kule meko, kwaye ukuveliswa kwamandla kuya kwandisa ukusetyenziswa kwamandla kulo mbuso! Oyena nobangela wokubola kwetheminali yebhetri: 1, ukuvuza kwetheminali; 2.

Uqhagamshelwano lwesiphelo kwimvula eneasidi; 3, ibhetri isetyenziswa rhoqo kwindawo emanzi; I-4, kukho ukuchasana koqhagamshelwano phakathi kwamakhadi omgca we-terminal. Ibhetri terminal corrosion unyango olusebenzayo: Ikhadi lomgca woqhagamshelo lisetyenziswa kweyona bhotolo ilungileyo. Inkcazo: I-oyile kunye nebhotela ayichaphazeli amandla okuqhuba, ibhetri entsha ifakwe, kucetyiswa ukuba ulahle amaconsi amabini kwi-terminal, inokuthintela ukubola.

Ngezantsi kubalulekile, ukutshaja kwangoku kukhulu kakhulu, i-voltage enye yokutshaja ibhetri idlula i-2.4V, kukho isiphaluka esifutshane okanye i-lead-acid yebhetri yesiphaluka esifutshane esibangelwa yisekethe emfutshane okanye ukukhutshwa kwendawo, ukunyuka kweqondo lokushisa, kunye nesiganeko sokungaphumeleli kwevalve ihlalutywa. Indlela.

I-1, ukunciphisa umbane wokutshaja, ukunciphisa i-voltage yokutshaja, khangela ukuba umzimba wevalve yokhuseleko uvaliwe. Ukukhutshwa kwentlawulo rhoqo. I-voltage ye-lead-acid ejikelezayo yebhetri kunye ne-voltage yokukhupha kwinkqubo yamandla e-UPS, ezininzi zazo eziye zathunyelwa kwixabiso elilinganisiweyo ngexesha lomzi-mveliso, kunye nobukhulu bokukhutshwa kwangoku kwanda ngokunyuka komthwalo, kwaye umthwalo kufuneka ulungelelaniswe ngokufanelekileyo.

Umzekelo, inani lezicelo zezixhobo zombane ezifana neekhompyutha. Kwiimeko eziqhelekileyo, umthwalo akufanele udlule i-60% yomthwalo olinganisiweyo we-UPS. Kolu luhlu, ibhetri ayikhuphi ngokugqithisileyo.

Ukugcinwa kwebhetri ye-lead-asidi kuya kulahlekelwa inxalenye yomthamo ngenxa yokuzikhupha, kwaye ngoko ke, ngaphambi kokuba ibhetri ye-lead-asidi isetyenziswe, umthamo oseleyo webhetri kufuneka umiselwe ngokwesekethe evulekileyo yebhetri, kwaye emva koko wongeze ibhetri ukongeza ibhetri. Ibhetri yeeshelufa zokulinda, ukutshaja okongeziweyo kufuneka kwenziwe rhoqo kwiinyanga ezi-3. Ungamisela ukuba ibhetri ilungile okanye imbi ngokulinganisa i-puffy battery open circuit.

2, njengomzekelo webhetri ye-12V, ukuba i-voltage yesiphaluka evulekile iphezulu kune-12.5V, ithetha ukuba amandla ebhetri angaphezu kwama-80%, ukuba i-voltage yesiphaluka evulekile ingaphantsi kwe-12.5V, kufuneka izaliswe ngokukhawuleza.

Ukuba i-voltage yesiphaluka evulekileyo ingaphantsi kwe-12V, ithetha ukuba umbane wokugcina ibhetri unokuba ngaphantsi kwama-20%, ibhetri ayikwazi. Xa ibhetri imfutshane, i-short circuit current inokufikelela kumakhulu e-amps. Uqhagamshelwano olufutshane lunxulumene, ubukhulu besiphaluka esifutshane sangoku, ngoko ke zonke iindawo ezidibanisayo ziya kuba nobushushu obuninzi, kwaye ukushisa kwekhonkco elibuthathaka kukhulu, uxhulumaniso luvuthelwa, i-short-circuit phenomenon.
