Ungalukhetha njani uluhlu olufanelekileyo lomvavanyi wombane?

1. Ukumelana novavanyo lwe-voltage, eyaziwa ngokuba yi-"high voltage dielectric test", ebizwa ngokuba "yi-standing voltage test".Ummiselo osisiseko wokukhetha uluhlu olufanelekileyo lwevoltheji yokumelana nomvavanyi kukusebenzisa umbane osebenzayo kabini wento eza kuvavanywa, kwaye emva koko wongeze iwaka leevolthi njengomgangatho wombane wovavanyo.Umbane wokuvavanya kwezinye iimveliso unokuba phezulu kune-2 × Umbane osebenzayo ngu-1000V.Umzekelo, uluhlu lwamandla ombane osebenzayo wezinye iimveliso lusuka kwi-100V ukuya kwi-240V, kwaye amandla ombane ovavanyo kwezo mveliso aphakathi kwe-1000V kunye ne-4000V okanye ngaphezulu.Ngokubanzi, iimveliso ezinoyilo “lokugquma kabini” zinokusebenzisa amandla ombane ovavanyo aphezulu kune-2 × Amandla ombane osebenzayo + 1000V eqhelekileyo.

I-2.Uvavanyo lokumelana nombane luchaneke ngakumbi kuyilo lwemveliso kunye nokwenza isampulu kunemveliso esemthethweni, kuba ukhuseleko lwemveliso luye lwamiselwa kuyilo kunye nenqanaba lovavanyo.Nangona kuphela iisampulu ezimbalwa ezisetyenziselwa ukugweba uyilo lwemveliso, uvavanyo lwe-intanethi ngexesha lemveliso kufuneka lube ngqongqo ngakumbi.Zonke iimveliso kufuneka zikwazi ukudlula imigangatho yokhuseleko, kwaye inokuqinisekiswa ukuba akukho mveliso ephosakeleyo iya kuphuma kumgca wokuvelisa.

3.I-voltage ephumayo yokuvavanya i-voltage tester kufuneka igcinwe kuluhlu lwe-100% ukuya kwi-120% yombane ochaziweyo.Ubuninzi bemveliso ye-AC yokumelana ne-voltage tester kufuneka igcinwe phakathi kwe-40Hz kunye ne-70Hz, kwaye ixabiso layo lencopho aliyi kuba ngaphantsi kwamaxesha e-1.3 ye-root mean square (RMS) ixabiso le-voltage, kwaye ixabiso layo eliphezulu aliyi kuba ngaphezulu kwamaxesha e-1.5. yengcambu yentsingiselo yesikwere (RMS) ixabiso lombane.

Iimveliso ze-4.Different zineenkcazo ezahlukeneyo zobugcisa.Ngokusisiseko, kuvavanyo lokumelana ne-voltage, i-voltage ephezulu kunomthamo oqhelekileyo osebenzayo usetyenziswa kwimveliso yovavanyo.Umbane kufuneka uhlale ixesha elithile.Ukuba ukuvuza kwangoku kwecandelo kugcinwe ngaphakathi koluhlu oluchaziweyo ngaphakathi kwexesha elichaziweyo, kunokumiselwa ukuba icandelo likhuselekile kakhulu ukuba lisebenze phantsi kweemeko eziqhelekileyo.Uyilo olugqwesileyo kunye nokukhethwa kwezinto ezilungileyo zokugquma kunokukhusela umsebenzisi kwingozi yombane
