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, i-alamu yemodyuli, 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 ubushushu be-ambient buphezulu kakhulu kwaye iqondo lokushisa ngaphakathi kwimodyuli lidlula ixabiso elibekiweyo, imodyuli iya kukhuselwa kwiqondo lokushisa elingaphezulu, isalathisi sokukhusela (ephuzi) kwipaneli yemodyuli iya kuba phezu. , 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.
