Inqanaba eliphezulu elimelana nobushushu obune-enamelled multi-strand engenanto umbala wobhedu oluxineneyo ukutshaja ngokukhawuleza kobonelelo lwamandla kwizithuthi zamandla emoto.

1, Isakhiwo kunye nemathiriyeli

1. I-Stranded wire: ekwabizwa ngokuba yi-multi-stranded wire, ibhekisela kwi-concentric stranding ye-multiple strands yocingo olulodwa lwe-enamelled lwenkcazo efanayo, kwaye isalathiso se-stranding somaleko ngamnye siguqulwa ngenye indlela.

2. Ubude be-Strand: umlinganiselo wesethi yokulinganisa umgama osebenzayo ukuya kwinani lokujika elijikiweyo yi-twist ubude (pitch) yocingo oluphothiweyo.

3. Inani lezabelo: njengoko kuchaziwe ngumthengi;

4. Isalathiso sokujija: sibhekisa kwicala lokuthatha kwinkqubo yemveliso, eyahlulahlulwe ngokubanzi ibeyi-positive (S), okt icala elihamba ngasekunene, nokubuya umva (Z), okt icala elichasene newotshi.

2, Umgangatho wosetyenziso

Jonga kwi-IEC JIS GB kunye neminye imigangatho yocingo olunamelled

3. Ukuchazwa kokuhlolwa

1. Iimfuno zenkangeleko: inkangeleko ebonakalayo icwebezelayo, ngaphandle komonakalo owenziwe ngoomatshini kumaleko wepeyinti, akukho lula ukukrazula ifilimu yepeyinti ngezikhonkwane, akukho cingo olujijekileyo olujijekileyo, ukutsiba kunye nezinye izinto, kwaye i-wiring icocekile kwaye ilungile.

2. Imfuneko yobude be-twist: thatha isampuli eyi-500mm, shiya i-100mm isibonelelo kuzo zombini iziphelo zesampulu ye-500mm, thatha intambo yocingo olunamelene ukusuka ekuqaleni ukuya ekuqaleni ukuya kukhulula, kwaye ngokuthe ngcembe ukhulule inani lokujika ukusuka ekupheleni ukuya ekupheleni b, kwaye urekhode umlinganiselo wenani lokujika kumgama olinganisiweyo. Ixabiso elifunyenweyo bubude be-twist yocingo lwe-enameled olunqamlekileyo, thatha indawo yedesimali enye, kwaye ukunyamezela ngokubanzi yi-± 1mm.

3. Indlela yokubala yedayamitha egqityiweyo yangaphandle yocingo oluxineneyo Z: D=1.155 ×√ N × d

D=ucingo olubhijelwe Z ubukhulu bangaphandle ubukhulu bomlinganiso=1.155 N=inani lemisonto yocingo oluphothiweyo d= ucingo olunamelo olunye Z inkulu egqityiweyo umphandle womlingane=1.155

Le fomula yokubala ingasetyenziselwa kuphela ireferensi.

4. Ukuhlolwa kwe-voltage ye-breakdown ye-enamelled wire stranded: phinda isampuli nganye kunye nobude be-500MM kwisiqingatha kwaye uyijike ngokucwangcisa kwiThebhile 1. Emva kokujija, nquma iziphelo zesampuli kwaye ushiye ubude obuphakathi kwe-120MM. Isiphelo socingo sihlukaniswe zibe zimbini ngokwenani leentambo. Esinye isiphelo sikwimo yesekethe evulekileyo, kwaye esinye isiphelo sintywiliselwa kwitoti njengesiphelo sokulinganisa. Bamba inxalenye yetoti yokudipha nge-electrode evumayo kunye nenye nge-electrode engalunganga, uze uvule isixhobo sokutshintshela ukuvavanya. Umgaqo kukunyusa ngokufanayo amandla ombane de ifilimu yepeyinti yesampulu iphuke. Ngeli xesha, ixabiso eliboniswe kwisixhobo lixabiso le-voltage yesampuli.

5. Intambo efakwe kwi-insulated wire yenziwe nge-multi-stranded enameled wire ngokusebenzisa i-machine stranding, kwaye i-voltage yayo iya kumiselwa ngokwenani leentambo. Umgangatho wombane uya kuthotywa njengoko inani leentambo linyuka. Ngeenkcukacha, phinda-phinda umlinganiselo ngokomgangatho wocingo olunamele. Jonga kwi (JISC3202-1994).

5.1 Xa inani leentambo (N) lingaphantsi kwama-20, amandla ombane wokuqhekeka kocingo olubiyelweyo ngu-V=i-voltage yokuqhawula yocingo olunye olunamelled * 90%.

5.2 Xa inani leentambo li-20 ≤ N ＜ 60, i-voltage ye-breakdown ye-stranded wire V = i-voltage yokuqhawula yocingo olulodwa lwe-enamelled * 80%.

5.3 Xa inani leentambo li-60 ≤ N ＜ 120, i-voltage yokuqhawula i-voltage ye-stranded wire V = i-voltage yokuqhawula yocingo olulodwa lwe-enamelled * 70%.

5.4 Xa inani leentambo li-N ≥ 120, i-voltage yokuqhawula yocingo oluvaliweyo V = i-voltage yokuqhawula yocingo olulodwa lwe-enamelled * 60%.
