SPD yo gutanga amashanyarazi ya sisitemu yo gutoranya ubuyobozi
Kwishyiriraho SPD kuri buri karere karinda inkuba, ukurikije igipimo cy’amashanyarazi make gisa n’amashanyarazi, kora ibyiciro by’amashanyarazi ukurikije icyiciro cya voltage irenze, insulasiyo yayo ihanganira urwego rwa voltage impulse irashobora guhitamo ihitamo rya SPD.Ukurikije igipimo cy’amashanyarazi make agaragara, kora ibyiciro byibikoresho byamashanyarazi ukurikije icyiciro cya voltage hejuru nkurwego rwibimenyetso, urwego rwo gupakira, urwego rwo gukwirakwiza no kugenzura, urwego rwo gutanga amashanyarazi.Gukwirakwiza kwayo kwihanganira urwego rwa voltage ni: 1500V, 2500V, 4000V, 6000V.Nkukurikije ibikoresho birinzwe byo gushyiramo ibikoresho bitandukanye hamwe numurabyo utandukanye wumuriro utandukanye wo kurinda inkuba, kugirango umenye aho ushyira SPD yo gutanga amashanyarazi nubushobozi bwo kumeneka.
Intera yo kwishyiriraho hagati ya buri rwego SPD ntigomba kurenza 10m, intera iri hagati ya SPD nibikoresho bikingiwe igomba kuba ngufi ishoboka, ntibirenze 10m.Niba bitewe nimbogamizi yumwanya wo kwishyiriraho, ntushobora kwemeza intera yo kwishyiriraho, hanyuma ukeneye gushiraho ibice biva hagati ya buri rwego SPD, kora nyuma yicyiciro SPD irinzwe nicyiciro cyambere SPD.Muri sisitemu yo gutanga amashanyarazi make, guhuza inductor birashobora kugera ku ntego yo gukuramo.
SPD yo gutanga amashanyarazi sisitemu yo guhitamo
Icyiza.guhora ikora voltage: nini kuruta ibikoresho bikingiwe, sisitemu ya max.Umuyoboro uhoraho.
Sisitemu ya TT: Uc≥1.55Uo (Uo ni sisitemu yo hasi ya voltage kugeza null umurongo wa voltage)
Sisitemu ya TN: Uc≥1.15Uo
Sisitemu ya IT: Uc≥1.15Uo (Uo ni sisitemu yo hasi ya voltage kumurongo)
Urwego rwo Kurinda Umuvuduko: munsi yubushakashatsi bwihanganira impulse ya voltage yibikoresho bikingiwe
Ikigereranyo cyo gusohora cyagenwe: cyagenwe ukurikije uko umurabyo uhagaze washyizweho na zone ikingira inkuba.
