Ubuyobozi bwa DC na AC SPD Ubwoko bwa 2 ku miterere y'izuba n'amashanyarazi

Nabonye ikintu kimwe cyabaye gihitana umusaruro w'amezi menshi, bityo buri gihe nkoresha imiti Igikoresho cyo kurinda Surge nk'ikintu cy'ingenzi gishushanyijeho, ntabwo ari ikintu cy'inyongera cyagenwe.

Ubuyobozi bwa DC na AC SPD Type 2 busobanura uburyo Igikoresho cyo kurinda Surge ibisubizo birinda imirasire y'izuba n'amashanyarazi ku ngufu zidasanzwe, binoza igihe cyo gukora, kandi bigabanya ikiguzi cy'igihe kirekire cyo kubungabunga no gusimbuza.

Niba ushishikajwe no gutanga serivisi ziteganijwe, ubwiza buhamye, n'igiciro gito cyo gutunga, gusobanukirwa ko ubwoko bwa 2 SPD ari bwo buryo bwiza bwo gutangiriraho.

Igikoresho cyo kurinda DC Surge ni iki?

Akenshi mbona ingaruka za DC zirengagijwe kugeza igihe ibikoresho byangiritse, bityo buri gihe ntangira isuzuma rya sisitemu ku ruhande rwa DC.

A Igikoresho cyo kurinda DC surge bigabanya ingufu zirenze urugero ku miyoboro ya DC binyuze mu kuyobya imbaraga zijya hasi mu mutekano, birinda ibikoresho bihujwe kwangirika.

Ntekereza ko uburinzi bwa DC surge ari bwo buryo bwa mbere bwo kwirinda mu mirasire y'izuba n'inganda. Imiyoboro ya DC igaragara, miremire, kandi akenshi ishyirwa hanze. Ibyo bituma ishobora kwibasirwa cyane n'inkuba ziterwa n'imirasire ndetse n'ihindagurika ry'ikirere. Igikoresho cyo kurinda Surge Ishyizwe ku ruhande rwa DC ikora mu masegonda make kandi igafata amashanyarazi akabije mbere yuko agera ku bikoresho by'ikoranabuhanga byoroshye.

Mu gushyiraho ibikoresho nyabyo, DC SPDs zirinda inverters, ibikoresho by'amashanyarazi bya DC, bateri, n'imiyoboro y'amashanyarazi. Iyo bitabayeho, kwiyongera gukomeye bishobora gutuma insulation ihungabana, semiconductor inanirwa gukora neza, cyangwa kwangirika burundu kw'imikorere. Nabonye ibi bibaho mu kurinda insulation ku nganda aho igihe cyo gukora kigera vuba kikavamo igihe ntarengwa cyo gutanga.

Igishushanyo cyiza cya DC SPD gihora gitekereza ku bwiza bw'ubutaka, uburebure bw'insinga, n'aho gishyirwa. Sinigeze mfata uburinzi bwa DC nk'igice cyihariye. Kigomba gukora nk'igice cy'uburyo bwose bwo gufunga no guhuza.

DC SPD Ubwoko bwa 2 ku mirasire y'izuba n'amashanyarazi

Ndasaba ubwoko bwa 2 DC SPDs ku bidukikije byinshi bikwirakwiza imirasire y'izuba n'ingufu.

Ibikoresho bya DC SPD Type 2 byagenewe kurinda sisitemu za DC inkuba ziterwa no kwiyongera kwa volteji mu bikoresho byo mu rwego rwo gukwirakwiza.

Mu mishinga yanjye, ubwoko bwa 2 DC SPDs ni bwo buryo bukunze gukoreshwa cyane. Bushyirwa munsi y'uburyo bw'ingenzi bwo kurinda inkuba kandi bugakemura ibibazo byo gusubira inyuma mu buryo bwiza. Bitandukanye n'ibikoresho byo mu bwoko bwa 1, bukoreshwa mu gukwirakwiza ibikoresho, mu dusanduku two guhuza ibikoresho, no mu bikoresho byinjizwamo inverter.

Nkunda uburinzi bwa Type 2 ku mirasire y'izuba yo ku gisenge, PV y'ubucuruzi, ndetse n'inganda nyinshi zikoresha SPD. Bitanga uburinganire bukomeye hagati y'urwego rw'uburinzi n'ikiguzi. Ibi ni ingenzi ku bashinzwe amasoko bashaka ibiciro biteganyijwe ariko badatakaza icyizere.

Dukurikije ubunararibonye, ​​ubwoko bwa 2 DC SPDs bugabanya cyane amakosa ya inverter ibangamira ibintu ndetse no kuzimya ibintu mu buryo budasobanutse. Binatuma ibikoresho biramba binyuze mu kugabanya imbaraga z'amashanyarazi. Ibyo bituma ikiguzi cyo kubungabunga kigabanuka kandi bigatuma sisitemu ihora ihagaze neza.

Ibipimo by'amashanyarazi ya DC SPD byasobanuwe

Nkunda kubona amakosa yo gupima voltage kurusha andi makosa yose yo guhitamo SPD.

Ibipimo by'amashanyarazi ya DC SPD bigomba kurenga ingufu ntarengwa zishoboka za sisitemu ya DC kugira ngo hirindwe ko yangirika vuba kandi itakaza uburinzi.

Sinigeze mfata SPD ishingiye kuri voltage nominel gusa. Ubushyuhe, imiterere y'imikorere, no kwaguka kwa sisitemu byose bigira ingaruka ku rugero nyarwo rwa voltage. Urugero, ubukonje bushobora gusunika voltage ya PV ifunguye kurenza agaciro ka nameplate.

Dore uko nsanzwe nhuza amanota ya DC voltage:

Gukoresha igipimo gikwiye cy'amashanyarazi bitanga icyizere Igikoresho cyo kurinda Surge ikora neza uko igihe kigenda aho gutsindwa bucece nyuma y'ibintu bike.

Imiterere y'inkingi y'ibikoresho byo kurinda DC Surge

Buri gihe nemeza imiterere ya pole mbere yo kwemeza DC SPD iyo ari yo yose.

Imiterere y'inkingi y'igikoresho cyo kurinda umuvuduko wa DC igena umubare w'abayobora umuvuduko w'amashanyarazi barinzwe n'uburyo ingufu z'umuvuduko w'amashanyarazi zishyirwa ku butaka.

Sisitemu nyinshi z'izuba zikoresha 2P DC SPDs kugira ngo zirinde ibyuma bitanga ingufu nziza n'ibibi. Mu buryo bugoye cyane, uburyo butandukanye bwo gusimbuza amashanyarazi bushobora gusaba izindi nkingi. Guhitamo imiterere idakwiye bishobora gutuma igice cy'amashanyarazi kigaragara.

Mu mishinga ya SPD y'inganda, mbere na mbere ngenzura imiterere y'ubutaka. Ibyo birinda ingaruka zihishe kandi bigatuma uburinzi bukomeza gukora neza.

Igikoresho cyo kurinda AC Surge ni iki?

Mfata uburinzi bwa AC nk'urwego rwa kabiri rw'ingenzi rw'uburinzi.

An Igikoresho cyo kurinda umuvuduko wa AC igabanya ingufu zirenze urugero ku nsinga z'amashanyarazi za AC, ikarinda imizigo n'ibikoresho byo kuyikwirakwiza kwangirika.

SPD za AC zirinda ubwiyongere bw'amazi bwinjira buva kuri grid cyangwa bugaterwa n'ibintu bihinduka. Muri sisitemu z'izuba, zirinda ibicuruzwa bisohoka muri inverter, switchboards, n'imizigo yo hasi.

Buri gihe nhuza AC na DC SPDs hamwe. Uburinzi bwihariye ntibukora neza nk'uburyo buhuriweho.

AC SPD kuri sisitemu imwe y'icyiciro kimwe n'icyiciro cya gatatu

Nhindura uburyo AC SPD ihitamo bitewe n'imiterere ya sisitemu.

SPD za AC zitoranywa hakurikijwe imiterere y'icyiciro kugira ngo zirinde uburinzi bw'umuraba buringaniye kandi bwuzuye.

Sisitemu z’icyiciro kimwe zikunze gukoresha uburyo bworoshye bwo gushushanya, mu gihe sisitemu z’icyiciro cya gatatu zisaba inzira zigoye zo kurinda. Nibanda ku guhuza no gushingira hasi kugira ngo wirinde stress ingana mu gihe cy’izamuka ry’ikirere.

Ubu buryo bukora neza cyane cyane mu kurinda umuvuduko w'amazi ku nganda aho uburinganire bw'imizigo n'uburyo ikomeza kugenda ari ngombwa.

Ibipimo by'amashanyarazi ya AC SPD n'imiterere yayo

Buri gihe nhuza amanota ya AC n'imiterere nyayo y'imikorere, ntabwo ari ibirango gusa.

Ibipimo by'amashanyarazi ya AC SPD n'imiterere yayo bigaragaza uburyo imiyoboro y'amashanyarazi ishyirwa mu bikorwa neza mu micungire y'amazu, ubucuruzi n'inganda.

Dore incamake yoroshye nkunda gukoresha:

Imiterere myiza ituma habaho kugabanuka kw'umuvuduko w'amaraso kandi bikarinda gusaza imburagihe kwa SPD.

Guhuza AC na DC SPD mu mikorere y'izuba

Buri gihe nkora uburyo bwo kurinda umuvuduko w'amazi nk'uburyo buhuriweho.

Gukoresha AC na DC SPDs hamwe bitanga uburinzi bw’ibice bigabanya ingufu zisigaye kandi bikongera ubwizigame muri rusange.

Guhuza bivuze gushyira DC SPD hafi y’aho PV arrays na inverters, na AC SPDs ahantu hakwirakwizwa. Ubu buryo bugizwe n’ibice bitandukanye ni ubusanzwe mu miterere y’umwuga yo guhagarika ingufu kandi butanga ingaruka nke cyane mu gihe kirekire.

Umwanzuro

Hitamo neza Igikoresho cyo kurinda Surge ingamba ubu zo kurinda sisitemu yawe, gahunda yawe, n'ishoramari ryawe ry'igihe kirekire.

Ibibazo Bikunze Kubazwa

Q1: Ese ubwoko bwa SPD bwo mu bwoko bwa 2 buhagije kuri sisitemu nyinshi z'izuba?

Yego. Ubwoko bwa 2 SPDs bwishyura ingaruka nyinshi zishobora guterwa n’ingufu ziterwa no kwiyongera kw’amashanyarazi mu bikoresho bisanzwe.

Ikibazo cya 2: Ese nshobora gukoresha AC SPDs kuri DC circuits?

Oya. AC na DC SPDs byakozwe mu buryo butandukanye kandi ntibishobora guhindurwa.

Q3: Ni gute gushingira ku mikorere ya SPD ari ingenzi?

Ubwiza bw'ubutaka bugira ingaruka zitaziguye ku buryo ingufu zikoreshwa mu gushyushya zisohoka.

Ikibazo cya 4: Ese SPDs zikeneye kwitabwaho?

Bigomba gusuzumwa buri gihe kandi bigasimburwa nyuma y'uko bigaragaye ko byarangiye.

Q5: Kuki ari ngombwa guhuza AC na DC SPDs?

Guhuza imikorere bigabanya ingufu zisigaye kandi bikongera ubwizigame bw'imikorere.
