Ese irinda gushyuha irinda umuvuduko w'amashanyarazi gutemba?

Ese Urinda Ubushyuhe Irinde kugwa Akamashini kagabanya urujya n'uruza rw'amashanyarazi?

Nakundaga gutakaza ibikoresho byose byo gusubiza ibintu mu gitondo kugeza ubwo nabajije ikibazo kimwe cyoroshye.

Oya, icyuma kirinda umuvuduko w'amashanyarazi ntigishobora kubuza icyuma cyawe gucika intege. Ikigo kirinda umuvuduko w'amashanyarazi gucika intege iyo umuvuduko w'amashanyarazi urenze urugero; ikigo kirinda umuvuduko w'amashanyarazi gifata gusa amashanyarazi make. Ibikoresho byombi mbibika mu mapine yanjye kuko bikemura ibibazo bibiri bitandukanye.

Komeza usome nzakwereka impamvu ibyo bikoresho byombi bidahinduranya n'uburyo bwo guhitamo igikwiye kuri buri kazi.

Gusobanukirwa uruhare rw'abarinda indwara zo mu bwonko muri Sisitemu z'amashanyarazi?

Nigeze gusimbuza ama-breaker atatu mbere yuko menya ko atari yo yari ikibazo—igikingira cyanjye cy’ingufu cyari gihishe ikibazo nyakuri.

Imashini irinda umuvuduko w'amashanyarazi ntigenzura umuriro w'amashanyarazi; ifata cyangwa igagabanya imivuduko ya voltage nyinshi imara amasegonda make. Iba iri kumwe n'umutwaro kandi ntijya ihagarika uruziga nk'uko icyuma gihagarika umuvuduko w'amashanyarazi kibikora.

Icyo igikoresho cyo kurinda umuvuduko w'amazi gikora mu by'ukuri

Igikoresho gikingira ingufu (SPD) gifata voltages za line-to-line cyangwa line-to-ground zizamuka hejuru y’urugero runaka, akenshi inshuro 1.5-2 z’amashanyarazi ya nominel. Ibi bibikora hifashishijwe metal-oxide varistors (MOVs) cyangwa imiyoboro ya gaze isohora. Igihe cyo gukora ni nanosegonda, ariko igipimo cy’ingufu ni joules magana make gusa ku duce duto two gushyiramo ingufu ndetse na kA zigera kuri 100 ku duce two gushyiramo ingufu. Ingingo y'ingenzi: ntikijya gifungura circuit. Umuriro ukomeza gutemba; spike ni yo yonyine ihindurirwa.

Aho tubishyira muri sisitemu

Impamvu ibi bifitiye akamaro abashinzwe amasoko

Iyo uguze breakers gusa hanyuma ugasiga SPDs, imashini zawe ziracyakora, ariko buri cumu rituma zimara igihe gito. Iyo uguze SPDs gusa hanyuma ukaziba breakers, ushobora gushya iyo habayeho impanuka ngufi. Zombi ndazibika mu ruganda rwanjye rwa Wenzhou kuko abakiriya benshi bo mu muryango w’ubumwe bw’ibihugu by’uburayi ubu basaba ko amabwiriza yo kugura ya EN 61643-4-11 yubahirizwa kimwe n’amabwiriza yo kugura.

Ni iki gitera ibyuma bigabanya umuvuduko w'amashanyarazi kugwa - kandi ni iki kidatera umuvuduko?

Narebye imodoka ya 32 A breaker ifunguka ku wa gatanu nyuma ya saa sita maze bidutwara igihe cyose kuko hari umuntu wongeyeho icyuma gishyushya.

Igikoresho gica intege iyo umuyoboro w'amashanyarazi urenze urugero rwawo rwa rukuruzi cyangwa ubushyuhe. Imiterere y'amashanyarazi, harmonics, cyangwa imiyoboro mito yo kuvogera ntabwo iwubangamira; umuyoboro w'amashanyarazi urenze urugero nyawo ni wo ubikora.

Inzira ebyiri z'ingenzi z'urugendo

Impamvu nyazo mbona mu kibuga

1. Gutwara ibintu byinshi cyane: Ushyiramo amashanyarazi abiri ya 1500 W mu muyoboro umwe wa 16 A. Umuyoboro ni 13 A kuri buri muyoboro, bityo 26 A yose hamwe kuri 16 A breaker. Igice cy'ubushyuhe kirashyuha kandi kigafungura nyuma y'iminota mike.
2. Umurongo mugufi: Insinga idakora neza ikora ku gasanduku k'imashini. Impedance imanuka igera hafi ya zeru, ingufu z'amashanyarazi zigakwirakwira kuri 1000 A, hanyuma igice cya rukuruzi kigakora mu masegonda make.
3. Ikosa ry'ibanze: Kimwe n'aho ari ngufi, ariko inzira inyura mu mugozi wo hasi. Niba igikoresho cyawe cyo gusohora amakuru gifite GFCI yubatswemo, kizafungura kuri 30 mA ingana.

Ni iki kidatera igikoresho gikoresha ikoranabuhanga

- Umuvuduko wa 300 V kuri 50 µs: Umuvuduko ntujya uwubona nk'umuvuduko w'amashanyarazi w'inyongera.

- Ikirahure cyo kurinda umuvuduko: MOV ikura amps nke kuri microsegonda; ntabwo ihagije kugira ngo ishyushye umugozi w'ibyuma bibiri.

- Urusaku rwa radiyo: Uru ni voltage, ntabwo ari umuriro.

Namaze icyumweru nkurikirana "ingendo zibangamira" kugeza ubwo naciyemo imashini isohora amatara ya laser ifite imbaraga nyinshi kuri C-curve breaker. Ikibazo cyarakemutse, nta bikoresho byo gusukura byari bikenewe.

Ni ryari ibikoresho byo kurinda ingufu ari ingenzi muri sisitemu yawe yo gukwirakwiza ingufu?

Natakaje PLC ya $3000 kubera inkuba, amaherezo nongeraho SPD kuri buri panel—nta kundi gusimbuza amabaruwa kuva icyo gihe.

Ukeneye ibikoresho bikingira insinga iyo urubuga rwawe rufite insinga ndende, ibikoresho by'ikoranabuhanga byifashishwa mu gupima, cyangwa imirabyo. Ntabwo bihagarika kugwa, ahubwo bihagarika ibyangiritse bibaho mbere yuko icyuma gica ibintu kigira icyo gikora.

Ibintu bitatu bishobora gutera ibyago biri mu mbonerahamwe

Imibare y'inyungu n'ikiguzi mpa abaguzi

Ubwoko bwa 2 SPD bufite amanota 40 kA butwara uruganda rwanjye $12 FOB Wenzhou. Ndayigurisha ku bacuruzi b’ibihugu by’Uburayi ku madolari 18. VFD imwe yazigamye yishyura units 400. Jeff Weaver, umuguzi wanjye usanzwe wo muri Amerika, yambwiye ko TCO ye yagabanutseho 8% nyuma yo kongeramo SPDs mu itsinda ryose rya breaker. Aracyakubita breaker iyo umukeka ugonze, ariko ntakisimbura imodoka buri gihembwe.

Inama zo gushyiramo ibikoresho ushobora gusangira n'umukozi wawe w'amashanyarazi

- Shyira agace ka SPD iruhande rw'agace kanini kagabanyamo uduce kugira ngo ukomeze gufata amapine ari munsi ya cm 50.

- Koresha insinga ya mm² 10 cyangwa nini; inductance ni umwanzi.

- Ongeraho agakoresho kabigenewe ka 20 A C-curve kuri SPD gusa; ibi birinda ingendo zibangamira igihe SPD igeze ku musozo w'ubuzima bwayo kandi ikagenda idafite intera.

Guhitamo uburyo bukwiye bwo kurinda isuri kuri porogaramu yawe?

Nigeze guhuza voltage ya SPD itariyo maze mbona 277 V kuri sisitemu ya 220 V; MOVs zanyoye itabi mu masegonda make.

Hitamo SPD ifite igipimo cy'amashanyarazi gihuye n'agaciro kawe k'umurongo ujya hasi, igipimo cy'amashanyarazi kiri hejuru y'umuvuduko witezwe, hamwe n'uburyo bwo gutsindwa bufunguka aho kuba bugufi.

Urutonde rw'ibyo noherereza abaguzi

Amahitamo ya OEM uruganda rwanjye rutanga

Dushobora gucapa ikirango cyawe, guhindura uburebure bw'insinga, cyangwa kongeramo umurongo ukoresha kure utanga ikimenyetso kuri SCADA yawe iyo SPD yananiwe. MOQ ni ibice 200, igihe cyo gutangira ni iminsi 15. Dutanga kandi raporo za CB, CE, na TUV kugira ngo ubashe kongeramo SPD ku byoherezwa bimwe n'ibyo wakoresheje nta mpapuro z'inyongera.

Amakosa asanzwe naretse gukora

1. Kuvanga ubwoko bwa 1 n'ubwoko bwa 2 ahantu hamwe—gukuba kabiri birahenda, nta nyungu.
2. Gukoresha 120 V SPD kuri serivise y'urumuri ya 277 V—bimara icyumweru kimwe.
3. Kwibagirwa guhuza breaker—amakabutura magufi ya SPD, ingendo za breaker, umusaruro urahagarara uko byagenda kose.

Ukorana n'uruganda rwizewe mu gutanga ibisubizo bya OEM/ODM?

Natangiye mfite metero kare 200 n'imashini imwe yo guteramo inshinge; uyu munsi uruganda rwacu rwa metero kare 2,000 rwohereza amakontena 40 ku kwezi kuko dufata buri mashini nk'aho ari umurongo wacu bwite.

Urushaho kwihuta, ikiguzi, n'amahoro mu mutima iyo ubonye SPD na breakers mu ruganda rumwe rutanga ibikoresho byo mu rugo, isuzuma ryuzuye, n'ibikoresho byo mu rugo ku rugo. Ntanga PO imwe, kohereza imwe, cyangwa undi nyuma yo kugurisha.

Yohereza imeri imwe ifite umubare w’ibikoresho byo gufunga, SPD, n’ibyuma bifunga. Dufunga igiciro mu gihe cy’amezi 12, twohereza kuri EXW cyangwa DDP Hamburg, hanyuma twongeramo ibirango by’Abadage. Yirinda kugenzura inshuro ebyiri kuko dushyira amafoto kuri buri ntambwe. Iyo itsinda rye rikoze ku gikoresho cyo gufunga mu gihe cy’ibizamini by’umurongo, baba bazi ko SPD ikirinze ibyuma, kandi ibice byombi byaturutse ku itsinda rimwe, umurongo umwe, urupapuro rumwe rwa QC.

Uburyo bwo gutangiza umushinga

1. Nyoherereza imeri igiciro wifuza n'ingano y'umwaka.
2. Tugarura igishushanyo cya 3D mu masaha 48.
