Ngethuba lokusebenza komthwalo wejeneretha, ukufakwa kwe-insulation kuya kuncipha ngokuthe ngcembe phantsi kwesenzo sentsimi yombane, ubushushu kunye nokungcangcazela komatshini ixesha elide, kubandakanywa ukuwohloka okupheleleyo kunye nokuwohloka kwenxalenye, okubangela iziphene.Uvavanyo lokumelana ne-voltage yeejeneretha yindlela esebenzayo kunye nethe ngqo yokuchonga amandla okufakelwa kweejeneretha, kwaye ngumxholo obalulekileyo wovavanyo lothintelo.Ke ngoko, uvavanyo lweHipot lukwayindlela ebalulekileyo yokuqinisekisa ukusebenza ngokukhuselekileyo kwejeneretha.
HV Hipot GDVLF Series 0.1Hz Programmable Ultra-low Frequency(VLF) High Voltage Generator
Indlela yokusebenza ye-ultra-low frequency ukumelana novavanyo lombane kwijenereyitha iyafana nendlela yokusebenza yentambo engentla.Oku kulandelayo yingcaciso eyongezelelweyo yeendawo ezahlukeneyo.
1. Olu vavanyo lunokwenziwa ngexesha lokunikezelwa, ukutshintshwa, ukutshintshwa ngokuyinxenye kwee-windings kunye novavanyo lwesiqhelo.Uvavanyo lokumelana ne-voltage yemoto ene-0.1Hz i-ultra-low frequency iyasebenza ngakumbi kwisiphene se-insulation yesiphelo sejenereyitha kune-frequency yamandla yokumelana novavanyo lombane.Ngaphantsi kwamandla ombane we-frequency voltage, ekubeni i-capacitive current equkuqelayo ukusuka kwintonga yocingo ibangela ukuhla kombane omkhulu xa iqukuqela kwi-semiconductor anti-corona layer ngaphandle kwe-insulation, i-voltage kwi-insulation yentonga yocingo ekupheleni iyancitshiswa;Kwimeko ye-ultra-low frequency, i-capacitor yangoku iyancipha kakhulu, kwaye ukuhla kwamandla ombane kwi-semiconductor anti-corona layer nako kuncitshiswe kakhulu, ngoko ke i-voltage kwi-insulation yokugqibela iphezulu, ekulula ukuyifumana iziphene.
2. Indlela yoqhagamshelo: Uvavanyo kufuneka lwenziwe ngezigaba, isigaba esivavanyiweyo sicinezelwe, kwaye isigaba esingavavanywanga sijikeleziswa kancinci emhlabeni.
3. Ngokweemfuno zemimiselo echaphazelekayo, ixabiso lencopho yombane wovavanyo linokumiselwa ngokwale fomyula ilandelayo:
Umax=√2βKUo Kwifomula, Umax: lixabiso eliphezulu le-0.1Hz yombane wovavanyo (kV) K: ngokuqhelekileyo ithatha i-1.3 ukuya kwi-1.5, ithatha ngokubanzi i-1.5
Uo: ixabiso elilinganisiweyo lejenereyitha yokujija iVoltage (kV)
β: I-coefficient elinganayo ye-0.1Hz kunye ne-50Hz yombane, ngokweemfuno zemimiselo yelizwe lethu, thatha i-1.2
Umzekelo: kwijenereyitha ene-voltage elinganisiweyo ye-13.8kV, indlela yokubala yovavanyo lwexabiso le-voltage yencopho ye-ultra-low frequency yile: Umax=√2× 1.2×1.5×13.8≈35.1(kV)
4. Ixesha lovavanyo lwenziwa ngokwemigaqo echaphazelekayo
5. Kwinkqubo yokumelana ne-voltage, ukuba akukho sandi esingaqhelekanga, iphunga, umsi kunye nomboniso wedatha ongazinzanga, kunokuqwalaselwa ukuba i-insulation iye yamelana novavanyo lovavanyo.Ukuze uqonde ngcono imeko ye-insulation, i-surface state ye-insulation kufuneka ibekwe iliso ngokubanzi ngokusemandleni, ngokukodwa kwiiyunithi ezipholileyo zomoya.Amava abonise ukuba ukujonga imbonakalo kunokufumana izinto ezingaqhelekanga zokugquma ijenereyitha engenakho ukubonakaliswa sisixhobo, njenge-corona yomhlaba, ukukhutshwa, njl.
