IZINYATHELO ZOKUQAPHELA ZOKUSEBENZISA AMA-TRANSFORMERS OKUHLOLWA NGOKUGCWALISA NGAMAFUTHA

Izinyathelo zokuphepha zokusebenzisa ama-transformer okuhlola acwiliswe ngamafutha yilezi ezilandelayo:

1. Xhuma isekethe yokusebenza ngokwesivivinyo esidingekayo. Igobolondo le-transformer yokuhlola ecwiliswe ku-oyela kanye negobolondo lebhokisi lokulawula (ithebula) kumele lisekelwe ngokuthembekile. Umugqa we-X-end (umsila we-voltage ephezulu) wokugoqa okuphezulu kwe-transformer yokuhlola ecwiliswe ku-oyela kanye nomugqa we-F wokugoqa kokulinganisa kumele kusekelwe ngokuthembekile.

2. Lapho kwenziwa ukuhlolwa kwe-cascade, i-terminal X ye-windings yesibili neyesithathu ye-low-voltage, i-terminal F ye-winding yokulinganisa kanye ne-terminal X (umsila we-voltage ephezulu) ye-windings ephezulu konke kuxhunywe ku-casing ye-transformer yokuhlola yalesi sigaba. I-casing yangaphandle ye-transformers yokuhlola ecwiliswe uwoyela ezingeni lesibili nelesithathu kumele isekelwe ngokusekelwa kokuvikela.

3. Ngaphambi kokuvula amandla, isilawuli se-voltage sebhokisi lokulawula le-transformer yokuhlola ecwiliswe ngamafutha (iyunithi) kumele silungiswe sibe yi-zero ngaphambi kokuvula amandla, ukuvala iswishi, bese siqala ukukhulisa i-voltage.

4. Jikelezisa isondo lesandla lomlawuli ngokulinganayo ukuze ukhuphule ingcindezi kusuka ku-zero. Izindlela zokukhulisa yilezi: indlela yokukhulisa okusheshayo, okungukuthi indlela yokukhulisa isinyathelo ngesinyathelo yama-20s; indlela yokukhulisa kancane, okungukuthi indlela yokukhulisa isinyathelo ngesinyathelo yama-60s; indlela yokukhulisa kancane kakhulu yokukhetha.

Ngemva kokuba i-voltage ikhuphuke kusukela ku-zero kuya ku-75% we-voltage yokuhlola elinganisiwe oyidingayo ngendlela ethile yokukhulisa kanye nesivinini, ikhuphukela ku-voltage elinganisiwe oyidingayo ngesivinini esingu-2% we-voltage yokuhlola elinganisiwe ngomzuzwana, bese unaka kakhulu ukulinganisa izinkomba zemitha kanye nesimo sento yokuhlola. Uma inkomba yethuluzi lokulinganisa kanye nesimo somkhiqizo ohloliwe kutholakala kungavamile ngesikhathi senqubo yokunyathelisa ye-transformer yokuhlola ecwiliswe uwoyela noma ngesikhathi sokuhlola, ingcindezi kufanele yehliswe ngokushesha, ukunikezwa kwamandla kufanele kunqanyulwe, futhi isimo kufanele sihlolwe.

5. Ngemva kokuhlolwa, isilawuli se-voltage kufanele sibuyiselwe endaweni engu-zero ngesivinini esingaguquki phakathi kwemizuzwana embalwa, bese ugesi unqanyulwa.

6. Ungadluli amapharamitha alinganiselwe. Ngaphandle uma kudingeka ekuhlolweni, ungalokothi uvumele amandla aphelele noma ukususwa kwamandla.

7. Uma wenza ukuhlolwa komfutho ophezulu, ngaphezu kokujwayelana nencwadi yemiyalelo yomkhiqizo, kuyadingeka futhi ukusebenzisa ngokuqinile amazinga kazwelonke afanele kanye nezinqubo zokusebenza. Bheka i-GB311-83 “Ukuhlanganiswa kokufakwa kokushisa kwemishini yokudlulisa enamandla aphezulu kanye nokuguqulwa, ubuchwepheshe bokuhlola amandla aphezulu”; “Izinqubo zokuhlola zokuvimbela imishini kagesi” njalo njalo.
