Guhitamo no gushiraho ibikoresho byo gukingira (SPD)

1.Ibipimo byo gutoranya

Mugihe duhitamo SPD kubikoresho, ntitugomba gutekereza gusa aho ibikoresho biherereye ahubwo tunareba intera iri hagati ya IT nibindi bikoresho, kandi igenamigambi rya gride y'amashanyarazi rigomba kubanza gutekerezwa (nka TN-S, TT, IT sisitemu, nibindi) .Gushyira SPD hafi cyane cyangwa kure cyane birashobora kugira ingaruka mbi mukurinda igikoresho (hafi cyane itera igikoresho na SPD kunyeganyega, kure cyane ntibishobora).

Byongeye kandi, gutoranya SPD bigomba no kuzirikana ibyagezweho kubikoresho, kwemeza ko ibice byatoranijwe bya SPD bifite ubushobozi bunini, gusuzuma SPD ukurikije amakuru yatanzwe nuwabikoze kandi hitabwa kubuzima bwa serivisi yaigikoresho cyo gukingira, hitamo kudasaza.

Twabibutsa kandi ko imbaraga zidasanzwe zikomeza gukora (UC) zo kurinda surge ziruta imbaraga zumuriro wigikoresho, kandi ko iki kibazo gishobora kuba gifite ingufu zirenze urugero (UT), hitabwa mugihe uhitamo SPD , Rimwe Hariho Ibi Birashoboka noneho noneho iigikoresho cyo gukingiraigomba kugira voltage iri munsi ya UC.Muri sisitemu y'ibyiciro bitatu (220 / 380V), gusa ibikoresho bimwe bidasanzwe (nk'ibikoresho bidasanzwe cyangwa ibikoresho by'amashanyarazi bisaba kurindwa) bizarindwa gukora amashanyarazi arenze urugero.

2.Urwego rwo kurinda inkuba hamwe na zone irinda inkuba

Intego yo gutoranya SPD ni ukumenya neza urwego rwo kurinda voltage (voltage isigaye) Hejuru, umuyaga mwinshi usohora, kugirango urebe ko Up iri munsi yurwego rwa voltage yibikoresho bikingiwe, hanyuma ukarinda ibikoresho.Ukurikije IEC60364-4-44, IEC60664-1 na IEC60730-1, mugihe uteganya, ukurikije imbonerahamwe ikwirakwiza yumurabyo, formulaire yo kugereranya amashanyarazi hamwe nimbonerahamwe yumurabyo, nkibyingenzi byingenzi byo guhitamo SPD.Kwinjira kwambere kubaka amakuru ya elegitoronike sisitemu yo kurinda inkuba.

Kuva kuri "Kubaka Sisitemu ya elegitoroniki Yamakuru Sisitemu yo Kurinda Umurabyo Tekinike" GB50343-2012 kugirango yemeze urwego rwo kurinda inkuba inyubako hamwe nibipimo byumurabyo nyuma yumurabyo wambere numurabyo wambere;Inkuba ishobora kuba ya amplitude yumurabyo irashobora kandi kuboneka uhereye kumurabyo ushobora gukuba wumurambararo wapimye wumurabyo wapimwe numwaka ugereranije ninkuba yumwaka T. E = 1-nc / n..

(1) Icyiciro A iyo E irenze 0,98;(2) icyiciro B iyo E irenze 0,90 iri munsi cyangwa ihwanye na 0,98;(3) icyiciro C iyo E irenze 0.80 iri munsi cyangwa ingana na 0.90;(4) icyiciro D iyo E iri munsi cyangwa ingana na 0.80;

Agace ko gukingira inkuba (LPZ) kagomba kugabanywamo agace katarinzwe, akarere karinzwe, akarere ka mbere karinzwe, akarere ka kabiri karinzwe hamwe n’akarere gakurikiranwa.(ishusho 3.2.2) igomba kubahiriza ibisabwa bikurikira:

Ahantu ho Kurinda Umurabyo (LPZOA): nta attenensiya yumurima wa electromagnetique, ubwoko bwibintu byose bishobora gukubitwa ninkuba, ni akarere gafunguye rwose.

Ahantu ho Kurinda Umurabyo (LPZOB): umurima wa electromagnetic ntushobora kwiyongera, ibintu byose ntibikunze guhura numurabyo utaziguye, ni ukugaragaza byuzuye ahantu harinda inkuba.

Agace ka mbere ko gukingira (LPZ1): bitewe nuburyo bwo gukingira inyubako, imirabyo itembera mu miyoboro inyuranye iragabanuka cyane kuruta mu gice gikingira inkuba (LPZOB), umurima wa electromagnetiki ubanza wongeyeho kandi ubwoko bwose bwubwoko bwose ibintu ntibishobora gukubitwa ninkuba.

Agace ka kabiri ko Kurinda (LPZ2): agace gakingira gakurikira kazanywe no kugabanuka kwumurabyo uterwa numuriro cyangwa amashanyarazi.

3.Kurinda ibikubiyemo kubirinda kubaga

Kugirango wirinde SPD kumuzingo mugufi kubera gusaza cyangwa izindi nenge, hagomba gushyirwaho uburyo bwo kurinda mbere ya SPD.Hariho uburyo bubiri bukunze gukoreshwa, bumwe nuburinzi bwa fuse, bumwe nuburinzi bwumuzingi.Nyuma yuko abategura barenga 50 babajije basanze abarenga 80% bategura bakoresheje imashini zangiza, mubyukuri biteye urujijo.Umwanditsi atekereza ko ari amakosa gushiraho uburyo bwo kurinda imiyoboro yamashanyarazi, kandi kurinda fuse bigomba gushyirwaho.

Kurinda Surge Protector nuburinzi bwumuzunguruko mugufi, ntakibazo kirenze, ukoresheje icyuma cyumuzunguruko gishobora gukoresha gusa uburinzi butatu (cyangwa bubiri-burinda) mumikorere yo guhagarika ako kanya.

Guhitamo ibikoresho birinda abashinzwe kubaga bigomba gushingira ku bushobozi buke bwumuzunguruko ku gikoresho cya SPD.Umuyoboro mugari wibikoresho bya surge protector mubisanzwe ni binini, niba ukoresheje icyuma cyumuzunguruko, noneho ukenera icyuma cyumuzunguruko cyubushobozi buke bwo kugabanuka.

Birakenewe kubara ubushyuhe bwumuriro wumuyoboro uhujwe nuburinzi bwa surge mugihe ukoresheje icyuma kizunguruka.Ukurikije ubushobozi bwumuzunguruko bugufi bwingingo, igice cyuyobora cyatoranijwe kizaba kinini cyane kandi insinga ntizoroshye.

Kugira ngo wumve Ihame ryibikoresho byo kurinda Surge, kanda kuriIhame ryibikoresho byo kurinda Surge
