Akamaro ka VLF ihangane nigikoresho cya voltage kuri generator ihangane nikizamini cya voltage

Mugihe cyo gukora imizigo ya generator, insulasiyo izagenda yangirika buhoro buhoro bitewe numurima wumuriro wamashanyarazi, ubushyuhe hamwe no guhindagurika kwa mashini mugihe kirekire, harimo kwangirika muri rusange no kwangirika igice, bikavamo inenge.Ikizamini cyo guhangana na voltage ya generator nuburyo bwiza kandi butaziguye bwo kumenya imbaraga zokwirinda za generator, kandi nikintu cyingenzi cyibizamini byo kwirinda.Kubwibyo, ikizamini cya Hipot nuburyo bukomeye bwo kwemeza imikorere ya generator.

HV Hipot GDVLF Urukurikirane 0.1Hz Programmable Ultra-low Frequency (VLF) Umuyoboro mwinshi

Uburyo bwo gukora bwa ultra-low frequency kwihanganira ikizamini cya voltage kuri generator isa nuburyo bwo gukora kuri kabili hejuru.Ibikurikira nubusobanuro bwinyongera bwahantu hatandukanye.
1. Iki kizamini gishobora gukorwa mugihe cyo guhererekanya, kuvugurura, gusimbuza igice igice cyo guhinduranya hamwe nibizamini bisanzwe.Ihangane rya voltage ya moteri hamwe na 0.1Hz ultra-low frequency ifite akamaro kanini kubwinenge ya insulation ya generator irangira kuruta ingufu zumuriro zihanganira ikizamini cya voltage.Munsi yumuriro wa voltage yumuriro, kubera ko ubushobozi bwa capacitive butemba buva kumurongo wumugozi butera kugabanuka kwumubyigano munini iyo unyuze muri semiconductor anti-corona layer hanze ya insulasiyo, voltage kumashanyarazi yinkoni yinsinga irangiye iragabanuka;Kubijyanye na ultra-low frequency, umuyoboro wa capacitori uragabanuka cyane, kandi voltage igabanuka kumurongo wa semiconductor anti-corona nayo iragabanuka cyane, bityo voltage kumurongo wanyuma irarenze, byoroshye kubona inenge.​
2. Uburyo bwo guhuza: Ikizamini kigomba gukorwa mubice, icyiciro cyapimwe kotswa igitutu, naho icyiciro kitageragejwe kigufi-kizunguruka kubutaka.
3. Ukurikije ibisabwa n’amabwiriza abigenga, agaciro ntarengwa ka voltage yikizamini gashobora kugenwa ukurikije formula ikurikira:

Umax = √2βKUo Muri formula, Umax: nigiciro cyo hejuru ya 0.1Hz ya voltage yipimisha (kV) K: mubisanzwe ifata 1.3 kugeza 1.5, mubisanzwe ifata 1.5

Uo: agaciro kagereranijwe ka generator stator ihinduranya Umuvuduko (kV)

.: Coefficient ihwanye na 0.1Hz na 50Hz ya voltage, ukurikije ibisabwa namabwiriza yigihugu cyacu, fata 1.2

Kurugero: kuri generator ifite voltage yagereranijwe ya 13.8kV, uburyo bwo kubara igipimo cyumubyigano wikigereranyo agaciro ka ultra-low frequency ni: Umax = √2 × 1.2 × 1.5 × 13.8≈35.1 (kV)
4. Igihe cyo gukora ikorwa hakurikijwe amabwiriza abigenga
5. Muburyo bwo guhangana na voltage, niba nta majwi adasanzwe, impumuro, umwotsi hamwe namakuru adahwitse yerekana, birashobora gufatwa nkaho insulasiyo yananiwe ikizamini cyikizamini.Kugirango twumve neza uko ibintu byifashe, imiterere yubuso igomba gukurikiranwa uko bishoboka kwose, cyane cyane kubice bikonje.Ubunararibonye bwerekanye ko kugenzura isura bishobora kubona ibintu bidasanzwe bitanga amashanyarazi adashobora kugaragazwa nigikoresho, nka corona yo hejuru, gusohora, nibindi.
