Intangiriro kubyiza nibibi byo kwihanganira ibizamini bya voltage

Ibibi byo Kwipimisha Bitaziguye (DC)

.Umuvuduko wongeyeho nawo uri hasi.Mugihe amashanyarazi yishyurwa ari manini cyane, byanze bikunze bizana urubanza rudakwiye nuwipimishije kandi ibisubizo byikizamini bitari byo.

.

(3) Bitandukanye n'ikizamini cya AC, DC ihanganira ikizamini cya voltage irashobora kugeragezwa gusa hamwe na polarite imwe.Niba ibicuruzwa bigomba gukoreshwa munsi ya voltage ya AC, iyi ngaruka igomba kwitabwaho.Ninimpamvu ituma abashinzwe umutekano benshi basaba gukoresha AC kwihanganira ikizamini cya voltage.

.Kubwibyo, amabwiriza menshi yumutekano arasaba ko niba DC ihanganye nikizamini cya voltage, ikizamini cyumubyigano kigomba kongerwaho agaciro kangana.

DC imaze kwihanganira ikizamini cya voltage kirangiye, niba ikintu kiri munsi yikizamini kitarasohoka, biroroshye gutera amashanyarazi amashanyarazi;DC yacu yose ihangane na voltage igerageza ifite imikorere yihuse ya 0.2s.DC imaze kwihanganira ikizamini cya voltage kirangiye, ikizamini Irashobora guhita isohora amashanyarazi kumubiri wapimwe muri 0.2s kugirango irinde umutekano wumukoresha.

Intangiriro kubyiza nibibi bya AC kwihanganira ikizamini cya voltage

Mugihe cyo kwipimisha voltage, voltage ikoreshwa na test ya voltage yipimishije kumubiri wapimwe igenwa gutya: kugwiza imbaraga zumurimo wumubiri wapimwe na 2 hanyuma wongere 1000V.Kurugero, voltage ikora yikintu cyapimwe ni 220V, mugihe ikizamini cyo kwihanganira voltage cyakozwe, voltage yumupimisha wapima ni 220V + 1000V = 1440V, muri rusange 1500V.

Ikizamini cyo guhangana na voltage kigabanijwemo AC ihanganira ikizamini cya voltage na DC ihanganira ikizamini cya voltage;ibyiza nibibi bya AC bihanganira ikizamini cya voltage nibi bikurikira:

Ibyiza bya AC bihanganira ikizamini cya voltage:

(1) Muri rusange, ikizamini cya AC cyoroshye kwemerwa nishami ryumutekano kuruta ikizamini cya DC.Impamvu nyamukuru ni uko ibicuruzwa byinshi bikoresha uburyo bwo guhinduranya ibintu, kandi ikizamini gisimburana gishobora kugerageza icyerekezo cyiza kandi kibi cyibicuruzwa icyarimwe, ibyo bikaba bihuye rwose nibidukikije aho ibicuruzwa bikoreshwa kandi biri kumurongo hamwe nimikoreshereze nyayo.

. ikizamini, keretse niba ibicuruzwa byunvikana kuri inrush voltage yunvikana cyane.

(3) Kubera ko ikizamini cya AC kidashobora kuzuza ubwo bushobozi bwayobye, nta mpamvu yo gusohora ikintu cyikizamini nyuma yikizamini, nikindi cyiza.

Ibibi bya AC bihanganira ikizamini cya voltage:

.ikigezweho.

.Ibi byongera ibyago kubakoresha.

Haba hari itandukaniro hagati ya arc gutahura nubu ikizamini?

1. Kubijyanye no gukoresha imikorere ya arc detection (ARC).

a.Arc nikintu gifatika, byumwihariko umuvuduko mwinshi wa pulsed voltage.

b.Imiterere yumusaruro: ingaruka zibidukikije, ingaruka zikorwa, ingaruka zibintu.

c.Arc ihangayikishijwe cyane nabantu bose, kandi nayo nikimwe mubintu byingenzi byo gupima ubuziranenge bwibicuruzwa.

d.Porogaramu ya RK99 igenzurwa na stand ya voltage tester yakozwe nisosiyete yacu ifite umurimo wo kumenya arc.Itanga urugero rwumuvuduko mwinshi wa pulse hejuru ya 10KHz unyuze hejuru-yungurura unyuze hejuru ya 10KHz, hanyuma ukayigereranya nigipimo cyibikoresho kugirango umenye niba yujuje ibisabwa.Ifishi iriho irashobora gushirwaho, kandi urwego rwurwego narwo rushobora gushyirwaho.

e.Nigute wahitamo urwego rwimikorere rugomba gushyirwaho numukoresha ukurikije ibicuruzwa nibisabwa.
