DC magetsi emagetsi anoita basa rakakosha mukuyedzwa kwebhatiri, maitiro anodiwa ekuongorora mashandiro ebhatiri, mhando, uye hupenyu hwesevhisi. A DC magetsi inopa yakagadzikana uye inogadziriswa voltage uye ikozvino kubuda kwekuedza kwakadaro. Chinyorwa ichi chichasuma misimboti yemagetsi eDC, mashandisiro azvo mukuyedzwa kwebhatiri, uye mashandisiro azvo nemazvo pakuedza zvinangwa.
1. Basic Misimboti yeDC Power Supplies
A DC magetsi mudziyo unopa yakagadzikana DC voltage, ine inobuda voltage uye ikozvino inochinjika sezvinodiwa. Nheyo yayo yakakosha inosanganisira kushandura alternating ikozvino (AC) kuita yakananga ikozvino (DC) kuburikidza nemasekete emukati uye kuendesa chaiyo voltage uye yazvino zvinoenderana nezvinodiwa zvakatemwa. Mamiriro akakosha emagetsi eDC anosanganisira:
Voltage uye Yazvino Kugadziridzwa: Vashandisi vanogona kugadzirisa inobuda voltage uye yazvino zvichienderana nezvinodiwa zvekuedza.
Kugadzikana uye Kurongeka: Yepamusoro-mhando DC magetsi emagetsi anoburitsa yakagadzikana uye yakaringana mavhoti emagetsi, akakodzera kuyedzwa kwebhatiri chaiko.
Dziviriro Zvimiro: Mazhinji emagetsi eDC ane akavakirwa-mukati-yakawandisa uye overcurrent kudzivirira mabasa kuti ave nechokwadi chekuchengetedza uye kudzivirira kukuvadzwa kwemidziyo yekuyedza kana mabhatiri.
2. Zvinodiwa Zvinokosha zveBattery Testing
Mukuyedzwa kwebhatiri, magetsi eDC anowanzo shandiswa kutevedzera kuchaja uye kuburitsa maitiro, zvichibatsira kuongorora mashandiro ebhatiri, kusanganisira kunyatsochaja, kuburitsa macurves, kugona, uye kuramba kwemukati. Zvinangwa zvekutanga zvekuyedzwa kwebhatiri zvinosanganisira:
Capacity Evaluation: Kuongorora kuchengetedza kwesimba uye kuburitsa kugona kwebhatiri.
Monitoring Discharge Performance: Kuongorora mashandiro ebhatiri ekuburitsa pasi pemamiriro ekutakura akasiyana.
Kuchaja Kubudirira Kwekuongorora: Kuonesa kugona kwekugamuchira simba panguva yekuchaja.
Hupenyu Hwayedzo: Kuita inodzokororwa kuchaja uye kuburitsa madhizaini kuti uone hupenyu hwesevhisi yebhatiri.
3. Zvishandiso zveDC Power Supplies muBattery Testing
DC magetsi emagetsi anoshandiswa mumamiriro akasiyana panguva yekuyedzwa kwebhatiri, kusanganisira:
Constant Current Charging: Kutevedzera zvinogara zvichichaja kuchaja bhatiri panguva yakatarwa, izvo zvakakosha pakuyedza kunyatsochaja uye kushanda kwenguva refu yekuchaja.
Constant Voltage Discharging: Kutevedzera inogara voltage kana kugara ichiburitsa ikozvino kuti udzidze kusiyana kwevoltage panguva yekubuda kwebhatiri pasi pemitoro yakasiyana.
Cyclic Charge-Discharge Testing: Kudzokororwa kuchaja uye kuburitsa kutenderera kunoyedzerwa kuongorora kusimba kwebhatiri uye hupenyu. DC magetsi inopa inonyatso kudzora voltage uye yazvino panguva idzi kutenderera kuti ive nechokwadi chechokwadi che data.
Load Simulation Testing: Nekumisa mitoro yakasiyana, magetsi eDC anogona kutevedzera kusiyana kwevoltage neazvino pasi pemamiriro akasiyana ekushanda, zvichibatsira mukuongorora mashandiro ebhatiri repasirese, sekubuda kwepamusoro-ikozvino kana mamiriro ekukurumidza kuchaja.
4. Mashandisiro eDDC Power Supply yeBattery Testing
Zvinhu zvakati wandei zvinofanirwa kutariswa kana uchishandisa DC magetsi ekuyedza bhatiri, kusanganisira voltage, yazvino, mutoro, uye yekuyedza nguva kutenderera. Matanho akakosha ndeaya anotevera:
Sarudza Yakakodzera Voltage Range: Sarudza voltage renji inokodzera kutsanangurwa kwebhatiri. Semuenzaniso, mabhatiri e-lithium anowanzoda marongero ari pakati pe3.6V ne4.2V, nepo mabhatiri e-lead-asidhi achiwanzoita 12V kana 24V. Magadzirirwo emagetsi anofanirwa kuenderana nebhatiri rezita remagetsi.
Seta Yakakodzera Yazvino Muganho: Isa iyo yakanyanya kuchaja ikozvino. Kuwedzeredza ikozvino kunogona kupisa bhatiri, nepo kusakwana ikozvino kungasaedza kushanda zvakanaka. Inokurudzirwa kuchaja marenji azvino anosiyana kune akasiyana mabhatiri marudzi.
Sarudza Dicharge Mode: Sarudza yekugara iripo kana yekugara voltage discharge. Muchigarire chemazuva ano, simba remagetsi rinobuda pane imwe nguva yazvino kusvikira bhatiri yemagetsi yadonha kusvika pamutengo wakaiswa. Mukugara kwevoltage mode, voltage inoramba iripo, uye ikozvino inosiyana nemutoro.
Seta Nguva Yekuyedza kana Kugona Kwebhatiri: Sarudza kutenderera-kuburitsa-kuburitsa kana nguva yekuyedza zvichienderana neyakayerwa bhatiri kugona kudzivirira kushandiswa zvakanyanya panguva yekuita.
Monitor Battery Performance: Gara uchitarisa bhatiri paramita senge voltage, ikozvino, uye tembiricha panguva yekuyedzwa kuti uone kuti hapana anomalies senge overheating, overvoltage, kana overcurrent inoitika.
5. Kusarudza uye Kushandisa DC Power Supplies
Kusarudza iyo yakakodzera DC magetsi emagetsi kwakakosha pakuyedza bhatiri. Mafungiro akakosha anosanganisira:
Voltage uye Yazvino Range: Iyo DC magetsi inofanirwa kugarisa voltage uye yazvino renji inodiwa pakuyedza bhatiri. Semuyenzaniso, kune 12V lead-acid bhatiri, magetsi ekupa inobuda renji anofanirwa kuvharidzira vhezheni yaro yezita, uye inobuda ikozvino inofanirwa kusangana nezvinodiwa.
Kunyatsoita uye Kugadzikana: Kuita kwebhatiri kunonzwa kune voltage uye kuchinja kwezvino, zvichiita kuti zvive zvakakosha kusarudza DC magetsi ane hupamhi hwepamusoro uye kugadzikana.
Dziviriro Zvimiro: Ita shuwa kuti magetsi anosanganisira overcurrent, overvoltage, uye pfupi-circuit dziviriro kudzivirira kukuvara kusingatarisirwe panguva yekuyedzwa.
Multi-Channel Output: Kuti uedze mabhatiri akawanda kana bhatiri mapaketi, funga nezvemagetsi ane akawanda-channel kubuda kuti uvandudze kuyedza kushanda.
6. Mhedziso
DC magetsi ekushandisa akakosha pakuyedzwa kwebhatiri. Voltage yavo yakagadzikana uye zvazvino kubuda zvinonyatso kutevedzera kuchaja uye kuburitsa maitiro, zvichibvumira kuongororwa kwakaringana kwekuita kwebhatiri, kugona, uye hupenyu. Kusarudza iyo yakakodzera DC magetsi uye kuseta inonzwisisika voltage, yazvino, uye mitoro mamiriro kunovimbisa huchokwadi uye kuvimbika kweyedzo mhinduro. Kuburikidza nesainzi nzira dzekuyedza uye kutonga chaiko neDC magetsi emagetsi, data rakakosha rinogona kuwanikwa kutsigira kugadzirwa kwebhatiri, kutonga kwemhando, uye optimization yekuita.
