Imiyalo yokusetshenziswa komkhiqizo
Umsebenzi Oyinhloko
- Gada ngokuzenzakalelayo umthamo wokunikezelatage kukho kokubili i-230V & 240V.
- Uma ingaphansi kwe-voltage (<207V) noma ngaphezulu-voltagI-e (>253V) itholiwe, i-Live, Neutral & Earth izohlukaniswa phakathi kwamasekhondi angu-5.
- Ngemuva kwe-under-voltage ukuzihlukanisa, isistimu izosetha kabusha ngokuzenzakalelayo lapho uhla olujwayelekile lokusebenza lubuyiselwa.
- Okwe-over-voltage ukuzihlukanisa, cindezela inkinobho YE-RESET ye-WVP32 ukuze usethe kabusha idivayisi.
Ukuhlolwa kwanyanga zonke
Uma usebenzisa inguqulo ye-RCBO, hlola nyanga zonke usebenzisa inkinobho yokuhlola.
Umsebenzi wokufaka
I-PME ifanele amashaja e-EV anokuvikela okubalulekile kokuvuza kwe-DC kodwa akukho ukutholwa kwephutha kwe-PME. Ayikho induku yomhlaba edingekayo uma usebenzisa leli bhodi lokusabalalisa.
- Ngemva kokuvula amandla, idivayisi ye-PME Fault Detection ihlola umthamo wokunikezwayotage imizuzwana emi-5. Uma ingaphandle kwemikhawulo, idivayisi yokubona amaphutha ye-PME iyasebenza. Ukuze usule, ukunikezwa kufanele kubuyele ngaphakathi kwemikhawulo evamile yokusebenza.
- Uma i-voltagiphakama ngaphezu kuka-253V futhi ayibuyi phakathi kwamasekhondi angu-5, isimo sephutha se-PEN siyakhubeka, kunqanyulwa ukuxhumana okubukhoma, okumaphakathi, noMhlaba emotweni.
- Umshayeli we-EV waziswa nge-high-voltage ufake isicelo emotweni ngaphansi kwalo mbandela ukuze kuhlolwe ukuphepha ngaphambi kokushayela.
Isingeniso
I-PME iyibhodi lokusabalalisa le-EV (Imoto Kagesi) elizonqamula ngokuphelele zonke izigaba nomhlaba uma kutholwa iphutha le-PME. Ihlinzeka amakhasimende ngesisombululo esiphephile nesithobela kakhudlwana sokushaja imoto kagesi. Asikho isidingo senduku yomhlaba uma kusetshenziswa leli bhodi lokusabalalisa. Ifanele amashaja e-EV anokuvikela okubalulekile kokuvuza kwe-DC kodwa akukho ukutholwa kwephutha kwe-PME.

Okuhlukile kwe-RCBO noma kwe-MCB (uma usebenzisa inguqulo ye-RCBO yokuhlola nyanga zonke usebenzisa inkinobho yokuhlola)
Umsebenzi wokufaka
- I-PME ibhodi lokusabalalisa i-EV elizonqamula ngokuphelele zonke izigaba nomhlaba uma kutholwa iphutha le-PME. Ihlinzeka amakhasimende ngesisombululo esiphephile nesithobela kakhudlwana sokushaja imoto kagesi. Asikho isidingo senduku yomhlaba uma kusetshenziswa leli bhodi lokusabalalisa. Ifanele amashaja e-EV (Electric Vehicle) anokuvikela okubalulekile kokuvuza kwe-DC kodwa akukho ukutholwa kwephutha kwe-PME. Ukulandela amandla okukhanyisa, idivayisi yethu yokubona amaphutha ye-PME i-voltage imizuzwana emi-5 bese inquma ukuthi ivolumutagi-e ingaphakathi kwemikhawulo evamile yokusebenza. (Awukho umehluko odingekayo phakathi kokunikezwa kwe-230Vac noma i-240Vac)
- Uma ingaphandle kwemikhawulo idivayisi yokubona amaphutha ye-PME iyasebenza. Ukuze usule, ukunikezwa kufanele kubuyele ngaphakathi kwemikhawulo evamile yokusebenza, futhi kungase kudinge ukucisha/ukukhanyisa umjikelezo uma ngabe imbangela ibe yi-over-vol.tagisimo e.
- Uma ngaphakathi kwemikhawulo, idivayisi yokuhlonza amaphutha ye-PME ivumela ukuxhumeka kokubukhoma, okungathathi hlangothi, nomhlaba emotweni, futhi iyaqhubeka nokuqapha ukunikezwa. Uma i-voltagI-e yehla ngaphansi kuka-207Vac futhi ayibuyi kufika kumasekhondi angu-5, isimo sephutha se-PEN siyakhubeka futhi uxhumo olubukhoma, oluphakathi nendawo, kanye nomhlaba luyasuswa emotweni.
- Nokho, i-voltagI-e dip ingase futhi ibangele isimo sephutha esifanayo. Ngakho-ke, idivayisi yokuhlonza amaphutha ye-PME ihlale iqapha impilo yokuhlinzeka futhi uma ibuyela ngaphakathi kwebanga elivamile lokusebenza, ivumela ngokuzenzakalelayo ukuxhunywa kabusha kokuphilayo, okungathathi hlangothi nomhlaba emotweni.
- Uma i-voltagiphakama ngaphezu kuka-253Vac futhi ayibuyi kufika kumasekhondi angu-5, isimo sephutha se-PEN siyakhubeka, futhi ukuxhumeka okubukhoma, okungathathi hlangothi, nokwasemhlabeni kuyasuswa emotweni.
Idivayisi yokubona amaphutha ye-PME iyaqhubeka nokuqapha indawo yokunikezela kodwa uma ibuyela ngaphakathi kwemikhawulo evamile yokusebenza isimo sephutha asisulwa ngaphandle kokungenelela okwenziwa ngesandla kumjikelezo wamandla. - Ngaphansi kwalesi simo, umshayeli we-EV uyaziswa ngevolthi ephezulutagesetshenziswa emotweni futhi angenza ukuhlola kokuphepha ngaphambi kokushayela imoto.
Kafushane Imisebenzi
Igada ngokuzenzakalelayo umthamo wokunikezelatage kuzo zombili izinto ezingu-230V & 240V ngaphandle kwesidingo sanoma yiziphi izilungiselelo zokushintshwa kwe-dip mathupha. Phakathi kwamasekhondi angu-5 uma kwenzeka i-under-voltage ngaphansi kuka-207V noma i-over-voltagengaphezulu kuka-253V Live, Neutral & Earth izohlukaniswa.
Ukulandela i-under-voltagI-e isolation izosethwa kabusha ngokuzenzakalelayo lapho uhla olujwayelekile lokusebenza lubuyiselwa.
Ukulandela i-over-voltagUkuhlukaniswa, ngezizathu zokuphepha, kuzodinga ukusetha kabusha mathupha.
FAQ
