Umwicanyi w'amashanyarazi ya Photovoltaque-DC Arc

Kubera ibisabwa kutabogama kwa karubone no hejuru ya karubone, inganda nshya zingufu ubu zirazwi cyane.Abantu bose bagenda bemeranya n’amashanyarazi y’amashanyarazi, kandi abantu benshi binjira mu nganda zifotora.Nyamara, urwego rwabantu bakora muriyi nganda ntiruringaniye, kandi abantu benshi ntibita kuri arc arc, bigatuma habaho impanuka nyinshi.

Arc ni ubwoko bwa gaz isohoka.Umucyo uhita ubyara umuyaga unyura muburyo bumwe, nkumwuka, byitwa arc.Byombi bitaziguye kandi bihinduranya umusaruro arcs.Rimwe na rimwe, iyo ducometse muri sock, tuzabona ibishashi, aribyo AC arc.Muri sisitemu ya DC, arc nkiyi iterwa numugozi wamafoto ya Photovoltaque yitwa DC arc.Ibinyuranye, sisitemu ya DC irashobora kubyara arc kuruta sisitemu ya AC, kandi iyo arc imaze kubaho, biragoye kuzimya arc.

Muri sitasiyo y’amashanyarazi, panne yifotora isohora amashanyarazi ya DC, ihinduka amashanyarazi ya AC nyuma yo kunyura mumashanyarazi.Umuvuduko wa panne ya PV ni muremure cyane, kuva kuri volt magana kugeza kuri ntarengwa ya V. V. Mubyukuri, volt mirongo icumi zirahagije kugirango habeho arc ya DC, ishobora gutanga ubushyuhe bwinshi bwa dogere 4200.Iyo panne enye zifotora zifatanije hamwe, voltage rusange izagera kuri volt 120.Ihuza ryiza kandi ribi ryinsinga rihita ritanga DC arc, kandi mumasegonda make, ubushyuhe bwo hejuru butuma umugozi wumuringa wa DC ushonga ako kanya ugahinduka ibitonyanga byumuringa hasi.Ahantu ho gushonga ni umuringa ni dogere 1083, umuringa ushongeshejwe niba utonyanga hejuru yinzu yimbaho ​​zinkwi zinkurikizi za villa ntushobora gutekereza, birashoboka cyane ko wateza inkongi y'umuriro, zimwe mumuriro wa villa yuburayi ziterwa nigisenge cyurugomero rwamashanyarazi rwa DC arc rwateye .Kubwibyo, DC arc kurinda amashanyarazi yamashanyarazi ni ngombwa cyane.

None, kubera iki sitasiyo yamashanyarazi ifotora DC arc?Impamvu nyamukuru zitera DC arc ni: itumanaho cyangwa fuse ihuza ntabwo ihagarikwa, bolt ya busbar ntikomera, ihuriro ni okiside, insinga ya insinga iragabanuka, kubika ibikoresho bifite inenge, nibindi.

Ni izihe ngaruka za DC arc ku mashanyarazi ya Photovoltaque?Iya mbere ni ibyangiritse ku bikoresho.Agasanduku ka kombineri, akabati ka DC, ibice bya bateri, uhuza, agasanduku gahuza, nibindi birashya.Iya kabiri ni ugutakaza ingufu.Kunanirwa kwose bizatera amashanyarazi make cyangwa ntayo.Iya gatatu ni ibihungabanya umutekano.Umuriro urashobora guhungabanya umutekano wumuntu numutungo.

Nibihe bishoboka ko arc amashanyarazi ikorerwa mumashanyarazi ya PV?Fata amashanyarazi ya 10MW kurugero, hano harahuza 80.000 ihuza agasanduku gahuza hamwe na 4000 ya terefone, wongeyeho guhuza weld imbere yibice bya batiri, akabati ka DC hamwe nimbere yimbere ya inverter, byose byiyongeraho byibuze 84.000, bityo niba amahirwe yo gutsindwa ari 1 kuri 10,000, hari 8 muri yo, bityo amahirwe yo kubaho ni menshi cyane.

Nigute twakwirinda DC Arc muri Photovoltaic Power Station?

Ubwa mbere, menya neza gukoresha ibicuruzwa bisanzwe kandi byujuje ibisabwa, ntabwo ari ibicuruzwa byiganano kandi bidahwitse.Nka Slocable'smc4 inline fuse umuhuzanagutandukanya agasanduku.
Icya kabiri, umubare wumutwe ugomba kugabanuka uko bishoboka.
Icya gatatu, abubatsi bagomba gukoresha ibikoresho byumwuga kandi bagomba guhugurwa kandi babishoboye mumahugurwa yimyuga nibizamini mbere yuko bashyirwa kumurimo.
Icya kane, nyuma yumuriro wamashanyarazi, hagomba gukorwa ubugenzuzi.
Icya gatanu, hagomba kubaho ibikoresho byo gutahura bihuye, nkiyi sensor ya DC arc, bazatabaza kandi bahagarike uruziga nibamara kubona DC arc kugirango bakureho akaga kihishe.
Icya gatandatu, hagomba kubaho urubuga rwo gukurikirana ingufu kugirango rukurikirane amakuru yimikorere mugihe nyacyo, kugirango hamenyekanye akaga kihishe, abakozi bashobora kumenyeshwa ako kanya kugirango bakemure.

Mubyukuri, DC arc ntabwo iteye ubwoba.Igihe cyose uzi neza uburyo bukwiye kandi ugakoresha ingamba za siyansi, urashobora gukumira no guhangana nabyo.Kimwe nimbaraga za AC murugo, umutekano uremewe rwose.Binyuze muburyo bwa tekiniki bujyanye, ikibazo cyo gukumira no kugenzura DC arc gishobora gukemurwa ku giciro gito.
