Kugenzura Umutekano no Gukora: Imiyoboro ya DC-Side Ihuza Wiring muri Inverters yo Kubika Ingufu

Mugihe gahunda yo kubika ingufu zo murugo zigenda zikundwa cyane, kurinda umutekano nigikorwa cyinsinga zabo, cyane cyane kuruhande rwa DC, nibyingenzi. Umuyoboro utaziguye (DC) uhuza imirasire y'izuba, bateri, na inverter ni ngombwa muguhindura ingufu z'izuba mumashanyarazi akoreshwa no kuyabika neza. Aka gatabo gatanga incamake yibitekerezo byingenzi, imikorere myiza, hamwe namakosa asanzwe wirinda mugihe ushyiraho no kubungabunga insinga za DC kuruhande rwububiko bwingufu zo murugo.

Gusobanukirwa DC-Uruhande rwingufu zo murugo Inverters

DC-uruhande rwububiko bwingufu niho amashanyarazi atemba atembera hagati yizuba ryizuba na banki ya batiri mbere yo guhinduka mumashanyarazi (AC) kugirango akoreshwe murugo. Uru ruhande rwa sisitemu ningirakamaro kuko ikora neza kubyara ingufu nububiko.

Mubisanzwe ingufu zizuba zuba, imirasire yizuba itanga amashanyarazi ya DC, anyura mumigozi nibindi bice kugirango yishyure bateri. Ingufu zabitswe muri bateri nazo ziri muburyo bwa DC. Inverter noneho ihindura amashanyarazi ya DC yabitswe mumashanyarazi ya AC kugirango itange ibikoresho byo murugo.

Ibyingenzi byingenzi bigize uruhande rwa DC harimo:

Imirasire y'izuba PV itwara amashanyarazi kuva kuri panne kugeza muri inverter na bateri.
Umuhuza uhuza insinga nibikoresho, byemeza kohereza neza.
Fuse na switch kumutekano, kugenzura no guhagarika imbaraga nkuko bikenewe.

Ibyingenzi Umutekano Ibitekerezo bya DC-Side Wiring

Ingamba zumutekano zikwiye zo guhuza DC kuruhande ningirakamaro kugirango hirindwe ingaruka zamashanyarazi no gukora neza igihe kirekire. Hano hari ibintu by'ingenzi ugomba kuzirikana:

Cable Insulation and Sizing: Gukoresha insinga zifite insulente ikingira birinda amashanyarazi kandi bigabanya ibyago byumuzunguruko mugufi. Ingano ya kabili igomba guhuza umutwaro uriho kugirango wirinde ubushyuhe bukabije nigabanuka rya voltage, bishobora kwangiza imikorere ya sisitemu kandi bigatera kwangirika.

Gukosora neza: Muri sisitemu ya DC, guhindura polarite bishobora gutera ibikoresho kunanirwa cyangwa kwangirika. Kugenzura niba insinga zifatika ari ngombwa kugirango wirinde imikorere mibi.

Kurinda birenze urugero: Kurenza urugero birashobora kwangiza ibice byamashanyarazi byoroshye kandi bigatera umuriro. Rinda sisitemu ukoresheje fuse na break break zihuye nubu bigenda muri DC-kuruhande.

Impamvu: Guhagarara neza byemeza ko umuyaga uwo ari wo wose uzimiye werekeza ku isi neza, bikagabanya ibyago byo guhitanwa n’amashanyarazi no gutuma gahunda ihagarara neza. Ibisabwa byibanze biratandukanye bitewe nigihugu ariko bigomba gukurikizwa byimazeyo.

Ubwoko bw'insinga zikoreshwa kuri DC-Kwihuza

Guhitamo insinga zibereye kuri DC-ihuza ni ngombwa kubwumutekano no gukora. Ubwoko bumwe busanzwe burimo:

Imirasire y'izuba (H1Z2Z2-K, UL ​​4703, TUV PV1-F) **: Izi nsinga zagenewe gukoreshwa hanze kandi zirwanya imirasire ya UV, ubushyuhe bwinshi, hamwe n’ibidukikije. Biranga urwego rwo hejuru rwo guhinduka, bigatuma biba byiza kuri sisitemu yizuba.

Ubworoherane Bwinshi Bwinshi: insinga za DC kuruhande zigomba kuba zishobora guhangana nubushyuhe bwo hejuru buterwa no guhora gutemba kwamashanyarazi kuva kumirasire yizuba kugera kuri inverter, cyane cyane mugihe cyamasaha yizuba.

Ubwiza bwemewe: Gukoresha insinga zemewe byemeza kubahiriza amahame yumutekano kandi bigafasha gukumira kunanirwa kwa sisitemu. Buri gihe hitamo insinga zujuje ubuziranenge bwa IEC, TUV, cyangwa UL.

Imyitozo myiza yo gushiraho DC-Side Wiring

Kugirango umenye umutekano nukuri kwizerwa rya DC-kuruhande, kurikiza imyitozo myiza:

Inzira ya kabili: Inzira nziza hamwe numutekano wa DC kugirango ugabanye guhura nikirere cyangiritse no kwangirika kwumubiri. Irinde kugunama gukabije, gushobora kunanura insinga kandi bigatera kwangirika kwimbere mugihe.

Kugabanya Umuvuduko Wamashanyarazi: Kugumana insinga za DC mugihe gito gishoboka bigabanya kugabanuka kwa voltage, bishobora kubangamira imikorere ya sisitemu. Niba intera ndende idashobora kwirindwa, ongera ubunini bwa kabili kugirango wishyure.

Ukoresheje Umuyoboro Ukwiye: Menya neza ko abahuza badafite ikirere kandi bahuza ninsinga zikoreshwa. Ihuza ridafite ubuziranenge rishobora gutera gutakaza ingufu cyangwa guteza inkongi y'umuriro.

Kugenzura no Kubungabunga buri gihe: Kugenzura insinga za DC buri gihe kugirango zishire, zirimo izangirika zangiritse, imiyoboro idahwitse, nibimenyetso bya ruswa. Kubungabunga inzira birashobora kubuza ibibazo bito guhinduka ibibazo bikomeye.

Amakosa Rusange Yokwirinda muri DC Wiring

Ndetse na sisitemu yateguwe neza irashobora kunanirwa kubera amakosa yoroshye mugikorwa cyo kwishyiriraho. Irinde iyi mitego isanzwe:

Intsinga zidafite ubuziranenge cyangwa Ubuziranenge-Gukoresha insinga: Gukoresha insinga ntoya cyane kuburemere bwa sisitemu ya none birashobora gutera ubushyuhe bwinshi, gutakaza ingufu, ndetse numuriro. Buri gihe hitamo insinga zishobora gukora ingufu zuzuye za sisitemu.

Ubuharike butari bwo: Guhindura polarite muri sisitemu ya DC birashobora kwangiza ibice cyangwa kunanirwa kwa sisitemu. Kugenzura inshuro ebyiri mbere yo guha ingufu sisitemu.

Intsinga zirenze urugero: insinga zuzuye zirashobora gutera insinga gushyuha. Menya neza umwanya uhagije no guhumeka, cyane cyane mumwanya ufunze nkibisanduku bihuza.

Kwirengagiza Kode yaho: Buri karere gafite kodegisi yumutekano wamashanyarazi, nka NEC muri Amerika cyangwa IEC ku rwego mpuzamahanga. Kunanirwa gukurikiza ibi birashobora kuganisha kuri sisitemu cyangwa ibibazo byamategeko.

Kubahiriza amahame mpuzamahanga

Sisitemu yo kubika ingufu, harimo insinga zabo za DC, zigomba kubahiriza amahame mpuzamahanga atandukanye kugirango umutekano ukore kandi wizewe:

Ibipimo bya IEC: Ibipimo mpuzamahanga bya komisiyo ishinzwe amashanyarazi (IEC) bitanga umurongo ngenderwaho wisi yose kumutekano wamashanyarazi no gukora.

Ibipimo bya UL: Ibipimo bya Laboratoire (UL) bikoreshwa cyane muri Amerika ya ruguru, bitanga ubuyobozi ku mutekano w’ibicuruzwa no gutanga ibyemezo.

NEC (Code of National Electrical Code): NEC itanga amategeko n'amabwiriza yo gushyira amashanyarazi muri Amerika. Gukurikiza amabwiriza ya NEC byemeza umutekano no kubahiriza.

Kubahiriza aya mahame ntabwo ari umutekano gusa; akenshi nibisabwa mubwishingizi kandi birashobora kugira ingaruka kuri sisitemu yemerewe gutera inkunga no kugabanyirizwa.

Gukurikirana no Kubungabunga DC-Kuruhande

Ndetse sisitemu yashyizweho neza isaba gukurikirana no kuyitaho buri gihe kugirango ikore neza. Dore uko wakomeza gukora:

Ubugenzuzi busanzwe: Teganya buri gihe kugenzura ibyangiritse kumubiri, kwambara no kurira, no guhuza. Shakisha ibimenyetso bya ruswa, cyane cyane mumiterere yo hanze.

Kugenzura imikorere ya sisitemu: Inverter nyinshi zizana na sisitemu yo kugenzura yemerera abakoresha gukurikirana umusaruro ningufu zikoreshwa. Ibikoresho byo gukurikirana birashobora kukumenyesha kubibazo nko gutakaza ingufu zitunguranye, bishobora kwerekana ikibazo cyinsinga.

Gukemura Ibibazo Byihuse: Niba hari ibimenyetso byerekana ko wangiritse cyangwa byangiritse bibonetse mugihe cyo kugenzura, gusana cyangwa gusimbuza ibice byangiritse ako kanya. Igikorwa cyihuse kirashobora gukumira ibibazo bito kwiyongera mugusana bihenze.

Umwanzuro

Umutekano n'imikorere yububiko bwimbaraga zo murugo bishingira cyane mugushiraho neza no gufata neza insinga za DC kuruhande. Ukurikije uburyo bwiza, ukoresheje ibikoresho byujuje ubuziranenge, kandi ukurikiza amahame y’ibanze, urashobora kwemeza uburyo bwizewe kandi bunoze bwo kubika ingufu zunganira urugo rwawe. Buri gihe ujye utekereza kugisha inama abahanga mubikorwa bigoye, cyane cyane iyo bisabwa kubahiriza amahame mpuzamahanga yumutekano.

Ukurikije aya mabwiriza, ntuzamura gusa umutekano wa sisitemu n'imikorere gusa ahubwo uzongerera igihe cyayo kandi wunguke byinshi mubushoramari bwawe.

Kuva yatangizwa mu 2009,Danyang Winpower Wire & Cable Mfg Co, Ltd.yagize uruhare runini mubijyanye no gukoresha insinga za elegitoroniki n’amashanyarazi mu myaka igera kuri 15, kandi yakusanyije ubunararibonye mu nganda no guhanga udushya mu ikoranabuhanga. Turibanda ku kuzana ubuziranenge, bwuzuye bwo kubika ingufu za sisitemu ihuza insinga ibisubizo ku isoko. Buri gicuruzwa cyemejwe cyane n’imiryango yemewe n’uburayi n’abanyamerika kandi irakwiriye sisitemu yo kubika ingufu za 600V kugeza 1500V. Yaba ingufu nini yo kubika ingufu cyangwa sisitemu ntoya yagabanijwe, urashobora kubona igisubizo gikwiye cya DC kuruhande rwumuti.

Ibyifuzo byerekana guhitamo insinga zimbere zo kubika ingufu za inverter

Muri iki gihe cyingufu zicyatsi kibisi, Winpower Wire & Cabl izakorana nawe mugushakisha imipaka mishya yubuhanga bwo kubika ingufu. Itsinda ryacu ryumwuga rizaguha urwego rwuzuye rwo kubika ingufu za tekinoroji yo kugisha inama hamwe ninkunga ya serivisi. Nyamuneka twandikire!
