Yintoni iModyuli yokuTjaja? Yeyiphi iMisebenzi yoKhuselo enayo?

 Imodyuli yokutshaja yeyona modyuli ibalulekileyo yoqwalaselo lonikezelo lwamandla. Imisebenzi yayo yokukhusela ibonakaliswe kwimiba yokufaka ngaphezulu / ngaphantsi kokhuseleko lombane, imveliso phezu kokhuseleko lombane/phantsi kwe-alarm yombane, ukurhoxiswa kombane omfutshane, njl njl. Umsebenzi”.

1. Yintoni imodyuli yokutshaja?

I-1) Imodyuli yokutshaja ithatha indlela yokutshatyalaliswa kobushushu edibanisa ukuzipholisa kunye nokupholisa umoya, kwaye iqhube i-self-cooling kumthwalo okhanyayo, ohambelana nokusebenza kwangempela kwenkqubo yamandla.

2) Yeyona modyuli yoqwalaselo ibalulekileyo yobonelelo lwamandla, kwaye isetyenziswa ngokubanzi kubonelelo lwamandla kwizitishi ukusuka kwi-35kV ukuya kwi-330kV.
2. Umsebenzi wokukhusela wemodyuli yokutshaja ngaphandle kwamacingo

1) Ukufaka ngaphezulu / ngaphantsi kokhuseleko lombane

Imodyuli inegalelo ngaphezulu/phantsi komsebenzi wokhuselo lombane. Xa igalelo lombane lingaphantsi kwe-313±10Vac okanye lingaphezulu kwe-485±10Vac, imodyuli ikhuselwe, akukho mveliso ye-DC, kwaye isalathisi sokukhusela (ephuzi) sivuliwe. Emva kokuba amandla ombane abuyele phakathi kwe-335±10Vac～460±15Vac, imodyuli iphinda iqalise ukusebenza ngokuzenzekelayo.

I-2) Ukukhuselwa kwe-overvoltage ephumayo / i-alamu engaphantsi kwe-alamu

Imodyuli inomsebenzi wokukhuselwa kwe-overvoltage ephumayo kunye ne-alamu engaphantsi kombane. Xa i-voltage ephumayo inkulu kune-293 ± 6Vdc, imodyuli ikhuselwe, akukho mveliso ye-DC, kwaye isalathisi sokukhusela (ephuzi) sivuliwe. Imodyuli ayinakubuyisela ngokuzenzekelayo, kwaye imodyuli mayicinywe kwaye emva koko ivulwe kwakhona. Xa i-voltage ephumayo ingaphantsi kwe-198±1Vdc, ii-alamu zemodyuli, kukho imveliso ye-DC, kunye nesalathisi sokukhusela (ephuzi) sivuliwe. Emva kokuba i-voltage ibuyiselwe, i-alarm ye-module ye-undervoltage iyanyamalala.

3. Ukurhoxiswa kwexesha elifutshane

Imodyuli inomsebenzi wokurhoxisa wesiphaluka esifutshane. Xa imveliso yemodyuli imfutshane-ijikelezwe, imveliso yangoku ayikho ngaphezu kwe-40% ye-current rated current. Emva kokuba i-short circuit factor isusiwe, imodyuli ibuyisela ngokuzenzekelayo umphumo oqhelekileyo.

4. Ukukhuselwa kwelahleko yesigaba

Imodyuli inomsebenzi wokukhusela ilahleko yesigaba. Xa isigaba segalelo silahlekile, amandla emodyuli anqunyelwe, kwaye umphumo unokulayishwa ngesiqingatha. Xa i-voltage yemveliso i-260V, ikhupha i-5A yangoku.

5. Ukukhuselwa kweqondo lokushisa ngaphezulu

Xa i-air inlet yemodyuli ivaliwe okanye iqondo lokushisa eliphantsi liphezulu kakhulu kwaye iqondo lokushisa ngaphakathi kwimodyuli lidlula ixabiso elimiselweyo, imodyuli iya kukhuselwa kwiqondo lokushisa elingaphezulu, isalathisi sokukhusela (ephuzi) kwiphaneli yemodyuli iya kuba, kwaye imodyuli ayiyi kuba nemveliso yombane. Xa imeko engaqhelekanga ihlanjululwa kwaye ukushisa ngaphakathi kwimodyuli kubuyela ngokuqhelekileyo, imodyuli iya kubuyela ngokuzenzekelayo ekusebenzeni okuqhelekileyo.
6. Ukhuseleko olungaphaya kwecala eliphambili

Kwimeko engaqhelekanga, i-overcurrent iyenzeka kwicala lokulungisa imodyuli, kwaye imodyuli ikhuselwe. Imodyuli ayinakubuyisela ngokuzenzekelayo, kwaye imodyuli mayicinywe kwaye emva koko ivulwe kwakhona.
