Yintoni iModyuli yokuTshaja? Yeyiphi imisebenzi yokukhusela enayo?

 Imodyuli yokutshaja yeyona modyuli ibalulekileyo yoqwalaselo lombane. Imisebenzi yayo yokukhusela ibonakala kwiinkalo zokhuseleko lwe-input over/under voltage, ukhuseleko lwe-output over voltage/under voltage alarm, ukurhoxiswa kwesekethe emfutshane, njl.njl. Umsebenzi”.

1. Yintoni imodyuli yokutshaja?

1) Imodyuli yokutshaja isebenzisa indlela yokusasaza ubushushu edibanisa ukuzipholisa kunye nokuzipholisa ngomoya, kwaye iqhuba ukuzipholisa xa umthwalo ulula, okuhambelana nokusebenza kwenkqubo yamandla.

2) Yeyona module ibalulekileyo yoqwalaselo lombane, kwaye isetyenziswa kakhulu kumbane wezikhululo ezingaphantsi ukusuka kwi-35kV ukuya kwi-330kV.
2. Umsebenzi wokukhusela wemodyuli yokutshaja engenazingcingo

1) Ukhuseleko lombane olungaphezulu/ngaphantsi kombane

Imodyuli inomsebenzi wokukhusela i-voltage engaphezulu/ngaphantsi kwe-input. Xa i-voltage yokufaka ingaphantsi kwe-313±10Vac okanye ngaphezulu kwe-485±10Vac, imodyuli ikhuselekile, akukho mveliso ye-DC, kwaye isalathisi sokukhusela (esityheli) sivuliwe. Emva kokuba i-voltage ibuyele phakathi kwe-335±10Vac～460±15Vac, imodyuli iqalisa ukusebenza ngokuzenzekelayo.

2) Ukhuseleko oluphumayo olugqithisileyo/i-alamu engaphantsi kwamandla ombane

Imodyuli inomsebenzi wokukhusela i-overvoltage yemveliso kunye ne-undervoltage alarm. Xa i-output voltage ingaphezulu kwe-293±6Vdc, imodyuli ikhuselekile, akukho DC output, kwaye isalathisi sokukhusela (umthubi) sivuliwe. Imodyuli ayinakubuyela ngokuzenzekelayo, kwaye imodyuli kufuneka icinywe kwaye iphinde ivulwe. Xa i-output voltage ingaphantsi kwe-198±1Vdc, ii-alamu zemodyuli, kukho i-DC output, kwaye isalathisi sokukhusela (umthubi) sivuliwe. Emva kokuba i-voltage ibuyiselwe, i-alamu ye-undervoltage yemveliso yemodyuli iyanyamalala.

3. Ukurhoxa kwesekethe emfutshane

Imodyuli inomsebenzi wokurhoxisa i-short-circuit. Xa i-output yemodyuli i-short-circuit, i-output current ayidluli kwi-40% ye-rating current. Emva kokuba i-short circuit factor isusiwe, imodyuli ibuyisela ngokuzenzekelayo i-output eqhelekileyo.

4. Ukhuseleko lokulahleka kwesigaba

Imodyuli inomsebenzi wokukhusela ukulahleka kwesigaba. Xa isigaba sokufaka singekho, amandla emodyuli anqongophele, kwaye imveliso ingafakwa isiqingatha. Xa i-voltage yokukhupha ingu-260V, ikhupha umbane we-5A.

5. Ukhuseleko olugqithisileyo kubushushu

Xa ukungena komoya kwimodyuli kuvaliwe okanye ubushushu obuphakathi buphezulu kakhulu kwaye ubushushu obungaphakathi kwimodyuli budlula ixabiso elibekiweyo, imodyuli iya kukhuselwa kubushushu obungaphezulu, isalathisi sokukhusela (esityheli) kwiphaneli yemodyuli siya kuba sivuliwe, kwaye imodyuli ayiyi kuba namandla okukhupha i-voltage. Xa imeko engaqhelekanga isusiwe kwaye ubushushu obungaphakathi kwimodyuli bubuyela kwisiqhelo, imodyuli iya kubuyela ngokuzenzekelayo kwisimo esiqhelekileyo.
6. Ukhuseleko oluphezulu lwecala eliphambili

Kwimeko engaqhelekanga, umbane ogqithisileyo uyenzeka kwicala lokulungisa imodyuli, kwaye imodyuli ikhuselekile. Imodyuli ayinakubuyela ngokuzenzekelayo, kwaye imodyuli kufuneka icinywe kwaye iphinde ivulwe.
