Muri iki gihe, tekinoroji yabaye iyambere mubuzima bwacu kandi kurinda ibikoresho byacu na sisitemu yamashanyarazi nibyingenzi. Abantu benshi batekereza kubikoresho byashyizwe kumashanyarazi ya AC mugihe cyo gukingira, ariko gukenera ibikoresho byo gukingira DC byiyongereye cyane mumyaka yashize. Ibi biterwa no kuzamuka kwa sisitemu yingufu zishobora kuvugururwa no gukomeza kwiyongera kubikoresho bikoreshwa na DC. Ishusho hepfo ni amahame yakazi, akamaro nuburyo ibikoresho byo gukingira DC birinda sisitemu y'amashanyarazi.
· Ibikoresho byo gukingira DC bizwi cyane nka DC SPDs ni ibikoresho byamashanyarazi byateganijwe kurinda ibikoresho bikoresha ingufu za DC hamwe nububiko kugirango amashanyarazi yihuta akururwa nigikorwa cya voltage yigihe gito. Inkuba irakubita, guhinduranya ibikorwa, guhuza amashanyarazi (EMI), cyangwa amakosa yo gutanga amashanyarazi bitera imitoma.
· Igikorwa cyibanze cya DC Surge Protector ni ukugenzura ingano yumuyaga unyura mubikoresho byo hepfo no kunyereza ingufu zikabije mumacukuzi. Niyo mpamvu ifasha mukurinda kwangirika kubikoresho byoroshye birimo bateri, inverter, ikosora, nizindi mashini zingenzi muri sisitemu ya DC.
· Hamwe nuburyo bwiza bwo kwishyiriraho, uzaba uri mumwanya wo gupfukirana ibihombo byinshi bishobora guturuka kumutwe. Ingaruka zibi biti bya voltage zirimo umuriro, cyangwa n’amashanyarazi.
· Bitewe no kubyimba imikoreshereze yingufu zishobora kuvugururwa nkuko byavuzwe haruguru, urugero; umuyaga wumuyaga hamwe nizuba ryamafoto (PV). Izi sisitemu mubisanzwe zitanga ingufu za DC, zigomba gukingirwa muburyo bukwiye kugirango amashanyarazi adaturuka hanze. Ibi byafashije icyifuzo gisaba ibikoresho byo kurinda DC kubaga.
· Hamwe na gari ya moshi isanzwe igenda, iyi buckle ifatanye neza iyobora gari ya moshi ni ngombwa, urasabwa kuyikoresha nta mpungenge. Byose byakurikiranwe, iyo ni umwobo munini urudodo rwa gari ya moshi wiring irakomeye kandi yoroshye.
· Byongeye kandi, hakenewe gukingirwa neza kuko ibikoresho byinshi bya elegitoronike, nkibigo byamakuru, sisitemu yitumanaho, hamwe n’imodoka zikoresha amashanyarazi, zishingiye ku mbaraga za DC. Ibyuma bya elegitoroniki nibikoresho birashobora kwangirika ku buryo budasubirwaho, biganisha ku gihe cyo gutinda gihenze kandi bishobora guhungabanya umutekano niba bidahwitse mu kurinda.
Ni ngombwa guhuza ibicuruzwa byimbere; ibi bizagufasha kumva ibicuruzwa byiza byo kugura. Zhejiang Mulang Electric Co, Ltd. Ubwiza bwingandaDC SPDsn'ikirangantego cyabo kidasanzwe, gikoreshwa na MLY1-C40 kuri DC1000V no hejuru.
Ibikoresho byo gukingira DC bigizwe nibice bitandukanye bikorana kugirango berekane icyerekezo cya surge no kurinda ibikoresho byo hasi. Ibyingenzi byingenzi birimo;
- MLY 1 modular
- Varistors ya metal oxyde (MOVs)
- Imiyoboro isohora gaze (GDTs)
- Inzira yo guhagarika inzibacyuho (TVS diode)
Fus
Uku kurinda kurinda gukoreshwa mugukingira izuba riyobowe numucyo nabwo burenze urugero. Ifasha kurekura ingufu nini cyane kumurongo w'amashanyarazi kwisi iri mubutaka kugirango ugabanye ingufu zirenze.
MOVs ni umurongo utagengwa na voltage-igenzurwa igaruka kuri voltage itanga inzira-yo guhangana-imbaraga nkeya. Buzuza umuyaga mwinshi hanyuma bakayitandukanya neza hasi, bakarinda ibikoresho bifitanye isano.
GDTs ni ibikoresho bifunze byuzuye byuzuyemo imyuka yoroheje ionize iyo ihuye numuvuduko mwinshi. Bashiraho umurongo uyobora ingufu ziyongera, kwihutisha imbaraga no gusubiramo ingufu kure yibikoresho byoroshye.
Diode ya TVS ni ibikoresho byifashishwa bigamije kurangaza ingufu zigihe gito kure ya elegitoroniki yoroshye. Bafite imbaraga nke zo gusenyuka kandi basubiza byihuse kumashanyarazi, birinda umuyaga mwinshi kubutaka.
Fuse ikora nkikingira ibyingenzi byinjira mumigezi idakenewe. Nuburyo bwo kwigomwa butemba iyo ingufu ziyongereye kurenza urugero rwazo, bigahagarika byinshi byangiza ibikoresho bifitanye isano.
Hano hari umurongo ngenderwaho wabakoresha ugomba gutemba nyuma yo kugura izi DC SPD kugirango urinde ibintu byamashanyarazi. Muri byo harimo;
- Koresha hagati ya 50Hz na 60Hz AC
- Shyira munsi ya 2000m hejuru yinyanja
- Gukoresha ubushyuhe bwibidukikije -40, +80
- Hamwe na MLY1, voltage ya terminal ntigomba kurenza igipimo cyayo gikomeza gukora voltage
- Gushiraho gari ya moshi isanzwe ya 35mm
Iyo habaye umuvuduko mwinshi wa voltage, igikoresho cyo gukingira DC cyerekana imbaraga zirenze kandi kigakora uburyo bwo kurinda. MOVs, GDTs, na TVS diode zitanga inzira-zidashobora kwihanganira imiyoboro ikabije, ikayiyobora neza.
Ku rundi ruhande, fus, ikora nkumurongo wanyuma wo kwirwanaho uhagarika imigendekere yikigezweho niba irenze igipimo ntarengwa cyibikoresho. Mugabanye bihagije umuvuduko wa voltage, DC SPDs yemeza ko ibikoresho byo hasi byakira amashanyarazi ahamye kandi arinzwe.
Inyungu nyamukuru yo gukoresha ibikoresho bya DC byongera imbaraga ni ukubungabunga ibikoresho bifitanye isano na voltage. Iminsi y'ibikoresho byongerewe kubera gukumira ibyangiritse bihenze ndetse nigihe cyo gutinda binyuze mu kuyobya ingufu zikabije kure.
Umuvuduko ukabije w’umuvuduko urashobora guteza umutekano muke cyane cyane ahantu hashobora kwibasirwa cyane nkibigo byamakuru cyangwa sitasiyo yumuriro wamashanyarazi. DC SPDs itanga urundi rwego rwumutekano mukugabanya ingaruka zishobora guterwa numuriro, amashanyarazi, cyangwa ibikoresho byananiranye.
Sisitemu y'amashanyarazi irashobora gukora neza cyane hamwe nibikoresho bya DC byokwirinda muri domicile. Kugabanuka kwingaruka zo gutsindwa gutunguranye cyangwa imikorere mibi ituma amashanyarazi adahagarara, biganisha ku kongera umusaruro no kunyurwa kwabakiriya.
Mw'isi ya none aho ibikoresho bya elegitoronike hamwe na sisitemu y’ingufu zishobora kugira uruhare runini mu mibereho yacu yo kuturinda ibyago by’amashanyarazi bishobora gupimwa.DC ibikoresho byo gukingiraGukora nkibice byingenzi mukurinda ibikoresho bikoreshwa na DC hamwe na sisitemu zigihe gito. Nibyingenzi gusobanukirwa amahame yakazi, ninyungu batanga kuko ibi birashobora kwemeza imikorere yizewe kandi iramba mubuzima bwacu no gushiraho amashanyarazi. Tekereza gushora imari muri DC SPD kugirango ugabanye ingaruka ziterwa na voltage kandi uzigame umutungo wacu wingenzi nka sisitemu ya PV kurusenge rwawe cyangwa umuyoboro w'itumanaho ukomeye.
