Ongororo yemarekodhi enhoroondo yeUPS system yakaratidza kuti, muna Chikumi 6, ese maUPS mayunitsi akange aita bvunzo yemaminetsi gumi nemashanu yekuburitsa bhatiri. Mushure mekudzoreredza main switch yemagetsi, 6-mineti yakaenzana kuchaja yakaitwa, ichiteverwa ne14-maminetsi ekuburitsa bhatiri bvunzo nemainjiniya emugadziri. Mushure mekuedzwa, iyo UPS system yakangoerekana yatanga mana akateedzana 12-awa yakaenzana mhosva, nechikamu chimwe nechimwe chakaparadzaniswa ne1-miniti yepakati, ichipedzisa pa5: 32 am munaJune 9. Kubva ipapo, mabhatiri akaramba ari mufloat charge mode.
Kumwe kuongorora kweiyo yekutanga UPS bhatiri marongero yakaratidza zvinotevera:
Upenyu hwebhatiri hwakaiswa kumwedzi makumi mana nemasere (makore mana), kunyangwe tarisiro yehupenyu hwebhatiri re12V inofanira kunge iri makore mashanu.
Kuchaja kwakaenzana kwakasetwa ku 'yakabatidzwa.'
Muganho wazvino wekuchaja wakaiswa ku10A.
The trigger for switching to equalized charger was set to 1A (the system would automatic switch to equalized chargeging if the float charge current over 1A, even though the default value for this model is 0.03C10 ~ 0.05C10, zvichireva kuti kuenzana kuchaja kunokonzereswa kana iyo inoyangarara charge ikozvino inosvika 3-5A, nekuda kwezvikonzero zvisingazivikanwi mugadziri uyu. 0.01C10, zvichireva kuti yakaenzana kuchaja yaizokonzereswa kana iyo inoyangarara charger ikozvino yasvika 1A).
Yakaenzana yekuchaja yekudzivirira nguva yakaiswa kune 720 maminetsi (yakaenzana kuchaja yaizomira otomatiki mushure memaawa gumi nemaviri).
3. Ongororo Yezvinokonzeresa Kukundikana
Zvichienderana nemamiriro ezvinhu ari pamusoro, maitiro ekukundikana anogona kuongororwa sezvinotevera:
Mapoka maviri emabhatiri eiyi UPS system anga achishandiswa kwemakore mana (hupenyu hwesevhisi hwemabhatiri e12V makore mashanu), uye huwandu hwebhatiri hwakanga hwadzikira zvakanyanya. Zvisinei, kusati kwakundikana, kuonekwa kwekunze kwebheteri kwaive kwakajairika, pasina zviratidzo zvekuputika. Imwezve wongororo yemarekodhi enhoroondo eUPS kubva muna Ndira 30, 2019 (zvinyorwa zvisati zvaitika zuva iri zvakajekeswa) kusvika Chikumi 6, 2020, zvakaratidza kuti UPS system yakanga yachaja gumi nemaviri yakaenzana, uye nguva yakareba isingapfuure maminetsi gumi nemashanu. Izvi zvinoratidza kuti yakaenzana yekuchaja nguva yakaiswa muUPS system isati yagadziriswa yaive ipfupi, maminetsi gumi nemashanu chete, uye iyo UPS system yenguva pfupi yekuchaja yakaenzana haizokonzerese kuti mabhatiri awedzere.
Mushure mekugadzirisa uye capacitor kutsiva, iyo UPS system yakatangazve. Iyo yekudzora pfungwa yakaratidza bhatiri serichangobva kubatana, saka yakatanga 6-maminetsi akaenzana kuchaja ichibva yachinjisa kuchaji yekuyangarara. Nekudaro, mushure mekuedzwa kwakatevera kwemaminetsi gumi nemana, iyo UPS system yakatanga otomatiki kuchaja yakaenzana kuti inyatso kuzadza mabhatiri. Nekuda kwemabhatiri ari kushandiswa kwemakore mana, simba ravo remukati rekuchengetedza chaji yadzikira, zvichikonzera kuti chaji yekuyangarara ipfuure 1A, zvichikonzera 1A yakaenzana yekuchaja chikumbaridzo chakaiswa muUPS system (iyo yakasarudzika kukosha kweiyo modhi ndeye 3 ~ 5A inoyangarara charger ikozvino kukonzeresa yakaenzana kuchaja, asi nekuda kwechimwe chikonzero 1A inogadziriswa). Izvi zvakakonzera kuti UPS system idzokorore kutanga yakaenzana kuchaja kutozosvikira bhatiri remukati rakavhurika reketi razoimisa (Zvikasadaro, iyo UPS system ingadai yakaramba ichidzokororwa yakaenzana kuchaja, izvo zvingadai zvakaita kuti boka rebhatiri ribate moto). Munguva iyi, mabhatiri akafamba mana anoenderera akaenzana ekuchaja kwemaawa makumi mana nemasere (kutenderera kwega kwega kwakambomira kweminiti imwe chete maawa gumi nemaviri asati atangazve kuchaja kwakaenzana). Mushure mekuchaja kwakaenzana kwenguva yakareba kudaro, mabhatiri akazopedzisira aita kuputika, uye kunyange mavharuvhu ekubuda nawo akaremara.
4. Mhedziso
Zvichienderana nezviri pamusoro pekutarisa uye kuongororwa, zvikonzero zvekutadza kwebhatiri mune ino UPS system ndezvizvi:
Chikonzero chakananga kwaive kuseta kwakashata kweiyo UPS system yekuchaja paramita, izvo zvakatungamira kuenderera kwakaenzana kuchaja kwemaawa makumi mana nemasere nekungotora maminetsi 1 chete pakati pekutenderera kwega kwega. Kunyangwe mabhatiri matsva haakwanise kumira kwenguva yakareba uye akanyanya kuenzana kuchaja, zvichikonzera kutadza kwebhatiri mune iyi kesi.
Iyo UPS system modhi ndeyekutanga dhizaini ine mashandiro anoita. Iyi yekare UPS modhi (yakagadzirwa makore makumi maviri apfuura) yakanga isina 'yakaenzana yekuchaja nguva yekudzivirira nguva' (mamwe mabhurendi anowanzo kuseta iyi nguva kusvika kumazuva manomwe), zvichikonzera kuenderera kwakawanda kwakaenzana kuchaja kutenderera.
Kushanda kwemabhatiri kwadzikira nekuda kwezera (makore mana ari musevhisi), nekutapudza simba rekubuda uye nekutadza kubhadharisa chaji. June 6 asati asvika, yakaenzana-ku-kuya-yangarara-chaji yekushandura chikumbaridzo chazvino chakaiswa zvakaderera zvisinganzwisisike (chete 1A yemabhatiri e100Ah). Iyo UPS system's default value ndeye 3 ~ 5A, asi vashandi vekuchengetedza vakaigadzirisa zvisingatsananguriki kuti 1A.
Iyo UPS system yanga ichishanda kwemakore gumi nemana, kupfuura zera rayo rekubvisa, zvichiita kuti zvikanganiso zvekuyera zvisadzivisike. Mhosho idzi dzinogona kunge dzakakonzera kuti sisitimu idzokorore kutanga yakaenzana kuchaja nekuda kwekusaonekwa kwazvino.
Sezvineiwo, dunhu rakavhurika mune rimwe masero ebhatiri rakadzivirira iyo UPS system kuti isaenderere mberi yakadzokororwa yakaenzana yekuchaja kutenderera mushure mechina yakaenzana kuchaja, nekudaro ichidzivirira mukana wekuti mabhatiri abate moto.
5. Kugadzirisa Matanho kune Kukundikana
Matanho ekugadzirisa anosanganisira zvinhu zviviri:
Kutanga, gadzirisa kwenguva pfupi iyo UPS bhatiri yekuchaja paramita:
Dzima iyo yakaenzana yekuchaja kuseta muUPS system.
Rongedza chinokonzeresa chazvino chekuchinja kubva kuchaji yekuyangarara kuenda kune yakaenzana kuchaja kuenda ku3A (kunyangwe 3A ichiri yakaderera, sezvo iyo yakasarudzika diki i3A, asi yakamboiswa ku1A).
Gadzirisa iyo yakaenzana yekuchaja yekudzivirira nguva kusvika paawa 1 (yakamboiswa kumaawa gumi nemaviri).
Chechipiri, hofisi yebazi yakatsiva mapoka maviri ebhatiri nemabhatiri ekuchengetedza, asi mabhatiri ekuchengetedza anokwana 50 Ah chete, saka anogona kungoshandiswa kune zvinangwa zvenguva pfupi. Pane zvirongwa zvekuendesa mutoro kubva kuUPS system kuenda kune mamwe magetsi mune ramangwana, kunyatsogadzirisa nyaya dzekuchengetedza magetsi.
