AMANQAKU OKUSETYENZISWA KWEE-TRANSFORMERS EZITYIWE NGE-OYILE

Amanyathelo okuthintela ukusetyenziswa kwee-transformers zovavanyo ezintywilisiweyo kwioyile ngala alandelayo:

1. Qhagamshela isekethe yokusebenza ngokwendlela yovavanyo olufunekayo. Iqokobhe le-transformer yovavanyo efakwe kwi-oyile kunye neqokobhe lebhokisi yokulawula (itafile) kufuneka zisekelwe ngokuthembekileyo. Isiphelo se-X (umsila we-voltage ephezulu) sokujikeleziswa kwe-voltage ephezulu kwe-transformer yovavanyo efakwe kwi-oyile kunye nesiphelo se-F sokujikeleziswa kokulinganisa kufuneka zisekelwe ngokuthembekileyo.

2. Xa kusenziwa uvavanyo lwe-cascade, i-terminal X yee-windings zesibini nezesithathu ze-low-voltage, i-terminal F ye-measuring winding kunye ne-terminal X (umsila we-high-voltage) ye-high-voltage winding zonke ziqhagamshelwe kwi-casing ye-test transformer yale nqanaba. I-casing yangaphandle yee-transformers zovavanyo ezintywilisiweyo kwi-oyile yenqanaba lesibini nelesithathu kufuneka isekelwe ngenkxaso ye-insulating.

3. Ngaphambi kokuba uvule umbane, umlawuli wevolthi yebhokisi yokulawula i-transformer yovavanyo oluntywilisiweyo kwioyile (iyunithi) kufuneka ilungiswe ibe yi-zero ngaphambi kokuba uvule umbane, uvale iswitshi, kwaye uqalise ukunyusa umbane.

4. Jikelezisa ivili lesandla lomlawuli ngokulinganayo ukuze unyuse uxinzelelo ukusuka ku-zero. Iindlela zokunyusa zezi: indlela yokunyusa ngokukhawuleza, oko kukuthi indlela yokunyusa inyathelo ngenyathelo yama-20; indlela yokunyusa kancinci, oko kukuthi indlela yokunyusa inyathelo ngenyathelo yama-60; indlela yokunyusa kancinci kakhulu yokukhetha.

Emva kokuba i-voltage inyuke ukusuka kwi-zero ukuya kwi-75% ye-voltage yovavanyo olulinganisiweyo oyifunayo ngendlela ethile yokunyusa kunye nesantya, inyuka iye kwi-voltage elinganisiweyo oyifunayo ngesantya se-2% ye-voltage yovavanyo olulinganisiweyo ngomzuzwana, kwaye unikele ingqalelo esondeleyo kumlinganiselo Izalathisi zemitha kunye nemeko yento yovavanyo. Ukuba isalathiso sesixhobo sokulinganisa kunye nemeko yemveliso evavanyiweyo zifunyenwe zingaqhelekanga ngexesha lenkqubo yokunyusa i-transformer yovavanyo entywilisiweyo kwioyile okanye ngexesha lovavanyo, uxinzelelo kufuneka lwehliswe ngoko nangoko, umbane kufuneka unqunyulwe, kwaye imeko kufuneka ihlolwe.

5. Emva kovavanyo, umlawuli we-voltage kufuneka abuyiselwe kwindawo engu-zero ngesantya esingaguqukiyo kwimizuzwana embalwa, emva koko umbane kufuneka ucinywe.

6. Musa ukudlula iiparameter ezilinganisiweyo. Ngaphandle kokuba kuyimfuneko xa kusenziwa uvavanyo, ungaze uvumele ukwenziwa kwamandla ombane apheleleyo okanye ukususwa kwamandla.

7. Xa usenza uvavanyo loxinzelelo oluphezulu, ukongeza ekuqhelaneni nencwadi yemiyalelo yemveliso, kubalulekile ukuphumeza ngokungqongqo imigangatho yesizwe efanelekileyo kunye neenkqubo zokusebenza. Jonga kwi-GB311-83 “Ulungelelwaniso lokufakelwa kwezixhobo zokudlulisa amandla aphezulu kunye notshintsho, iteknoloji yovavanyo lombane ophezulu”; “Iinkqubo zovavanyo lokuthintela izixhobo zombane” njalo njalo.
