Ukumelana nebhethri kwangaphakathi kuyinkomba ebalulekile yokuhlola impilo nempilo yesevisi yamabhethri. Ngokuhamba kwesikhathi, ukumelana kwangaphakathi kuyanda kancane kancane, kube nomthelela omubi ekusebenzeni. Lokhu kungaholela emazingeni okukhipha amanzi kancane, ukulahlekelwa amandla aphezulu, namazinga okushisa aphakeme okusebenza. Ikakhulukazi, lapho ukumelana kwangaphakathi kudlula u-25% yenani elivamile, umthamo webhethri wehla kakhulu, ubeka engcupheni ukuzinza kwesistimu. Ngakho-ke, ukuqapha okuguquguqukayo kwesikhathi sangempela kokumelana kwangaphakathi kwebhethri kubalulekile.
1. Indlela Yokukhipha Eqondile Yamanje (DC).
Le ndlela ihlanganisa ukukhulula ibhethri ngamandla aphezulu nokubala ukumelana kwangaphakathi ngokusekelwe ekwehleni kwe-voltage. Nakuba ihlinzeka ngokunemba kwesilinganiso esiphezulu, ibangela ukusabela kwe-polarization ngaphakathi kwebhethri, isheshisa ukuguga. Ngenxa yalokho, le ndlela isetshenziswa ngokuyinhloko ezigabeni zokukhiqiza zocwaningo kanye nokuhlola futhi ayifanele ukuqapha isikhathi eside.
2. I-Alternating Current (AC) Indlela Yokuvimbela
Ngokusebenzisa igagasi elishintshayo lefrikhwensi ethile kanye nezimiso zoMthetho we-Ohm kanye namandla, le ndlela ikala ukumelana kwangaphakathi. Ngokungafani nendlela yokukhishwa kwe-DC, indlela ye-AC impedance igwema ukulimaza impilo yebhethri futhi inikeza imiphumela encike kancane imvamisa. Izilinganiso ezithathwe imvamisa ye-1kHz ngokuvamile zizinzile kakhulu. Le ndlela isetshenziswa kakhulu embonini futhi ifinyelela ukunemba okuphezulu, nge-margin of error phakathi kuka-1% no-2%.
I-DFUN ithuthukise ukuthuthuka kwendlela yendabuko ye-AC—i-AC Low Current Discharge Method. Ngokusebenzisa ijika elishintshayo elingekho ngaphezu kuka-2A kanye nokulinganisa ngokunembile ukushintshashintsha kwamandla kagesi, ukumelana kwangaphakathi kwebhethri kungabalwa ngokunembile ngesikhathi esifushane (cishe isekhondi elilodwa).
Izinzuzo Eziyinhloko:
Ukunemba Okuphezulu: Ukunemba kwesilinganiso kusondele ku-1%, nemiphumela ecishe ifane naleyo yezinkampani zangaphandle ezifana ne-Hioki ne-Fluke.
Ukumelana Kwangaphakathi |
2V Ibhethri: 0.1 ~ 50 mΩ |
Ukuphindaphinda: ±(1.0% + 25 µΩ) |
Ukulungiswa: 0.001 mΩ |
12V Ibhethri: 0.1 ~ 100 mΩ |
Awukho Umthelela Empilweni Yebhethri: Ngobubanzi obuncane bokukhipha bamanje kanye nobuncane bokuphuma, le ndlela ayilimazi ibhethri noma isheshise ukuguga.
Ukuqapha Kwesikhathi Sangempela: Kuvumela ukutholwa kwesikhathi sangempela kwesimo sebhethri, kuvimbele ngempumelelo ukuwohloka kokusebenza okubangelwa ukwanda kokumelana kwangaphakathi.
Ukusetshenziswa Okuhlukahlukene: Lobu buchwepheshe abusebenzi kuphela kumabhethri e-lead-acid kodwa futhi busebenza kahle ekuhloleni ukumelana kwangaphakathi kwezinye izinhlobo zebhethri.
Qinisekisa ukuthi amabhethri akho ahlala esesimweni esifanele, uthuthukise ukuzinza nokuthembeka kwamasistimu akho wamandla.
