Umgama okhuselekileyo we-high-voltage line.Uthini umgama okhuselekileyo?
Ukuthintela umzimba womntu ukuba ungachukumisi okanye usondele kumzimba wombane, kunye nokuthintela isithuthi okanye ezinye izinto ukuba zingangqubani okanye zisondele.
umzimba wombane obangela ingozi, kuyimfuneko ukugcina umgama othile kumzimba wombane, oba ngumgama okhuselekileyo.
Zingaphi iimitha kumgama okhuselekileyo?
Khumbula: ukuba mkhulu umgangatho wombane, umgama wokhuseleko mkhulu.
Jonga le theyibhile ilandelayo.ImiGaqo yoMsebenzi woKhuseleko lwaMandla oMbane waseTshayina inika umgama okhuselekileyo phakathi kwabasebenzi kunye neentambo zombane eziphezulu ze-AC.
| Ubuncinci umgama okhuselekileyo ukusuka kwiintambo zothumelo ezihamba phezulu kunye namanye amaqumrhu ahlawuliswayo | |
| Inqanaba lamandla ombane (KV) | umgama okhuselekileyo(m) |
| ＜1 | 1.5 |
| 1-10 | 3.0 |
| 35~63 | 4.0 |
| 110 | 5.0 |
| 220 | 6.0 |
| 330 | 7.0 |
| 500 | 8.5 |
Ngaba ikhuselekile ngokupheleleyo ngaphandle kokuchukumisa umgca we-voltage ephezulu?
Abantu abaqhelekileyo baya kukholelwa ngempazamo ukuba nje izandla kunye nemizimba yabo ingachukumisi umgca we-voltage ephezulu, baya kukhuseleka ngokupheleleyo.Yimpazamo enkulu le!
Eyona meko ilandelayo: nokuba abantu abawuchukumisi umgca we-high-voltage, kuya kubakho ingozi kumgama othile.Xa umahluko wombane
inkulu ngokwaneleyo, umoya ungonakaliswa kukutshitshiswa kombane.Kakade ke, okukhona umgama womoya umkhulu, kokukhona kunqabile ukuba kuphulwe.Umgama owaneleyo womoya
ukufikelela kwi-insulation.
Ngaba ucingo olunombane ophezulu “luyarhabula”?
Xa i-high-voltage wire ihambisa umbane, intsimi yombane eyomeleleyo iya kwenziwa malunga necingo, eya kuthi i-ionize emoyeni kwaye yenze ukukhutshwa kwe-corona.
Ke xa usiva isandi esithi “sizzling” kufutshane nomgca wevoltage ephezulu, ungathandabuzi ukuba siyakhupha.
Ngaphezu koko, okukhona inqanaba lombane liphezulu, kokukhona i-corona yomelele kunye nomsindo omkhulu.Ebusuku okanye kwimozulu yemvula kunye nenkungu, i-halos eluhlaza okwesibhakabhaka kunye nemfusa ingenzeka
kananjalo iqwalaselwe kufutshane ne-220 kV kunye ne-500 kV yeentambo zothumelo lwe-voltage ephezulu.
Kodwa ngamanye amaxesha xa ndihamba esixekweni, andicingi ukuba kukho ingxolo “eyothusayo” kwiintambo zombane?
Oku kungenxa yokuba iintambo zokuhambisa i-10kV kunye ne-35kV kwindawo yasezidolophini ikakhulu zisebenzisa iingcingo ezigqunyiweyo, ezingayi kuvelisa i-ionization yomoya, kwaye inqanaba lombane liphantsi,
ubunzulu be-corona bubuthathaka, kwaye isandi esithi "sizzling" sigqunywa lula sisigodlo esijikelezileyo kunye nengxolo.
Kukho intsimi yombane eyomeleleyo ejikeleze imigca yokuhambisa i-voltage ephezulu kunye nezixhobo zokuhambisa amandla ombane aphezulu.Iikondaktara kulo mmandla wombane ziya kuba nazo
Umbane owenziweyo ngenxa yokungeniswa kwe-electrostatic, ngoko ke abantu abanesibindi ngakumbi banombono wokutshaja iiselfowuni.Kubi ukuba nenkcubeko.Olu luthotho lwe
ukufa.Musa ukuyizama.Ubomi bubaluleke ngakumbi!Uninzi lwexesha, ukuba usondele kakhulu kumgca we-high-voltage.
