Amadivayisi wokuvikelwa kwe-DC Surge: Ukuvikela izinhlelo zakho zikagesi

Ezinsukwini zamanje, ubuchwepheshe buye baba phambili ezimpilweni zethu futhi buvikele izinto zethu kanye nezinhlelo zikagesi kubaluleke kakhulu. Iningi labantu licabanga ngamadivayisi afakwe emigqeni yamandla e-AC Uma kuziwa ekuvikelweni kwamandla ancishisiwe, kepha isidingo samadivayisi wokuvikela ukuvikelwa kwe-DC seke sanda kakhulu eminyakeni yamuva. Lokhu kungenxa yokukhuphuka kwezinhlelo zamandla avuselelekayo kanye nokwanda okuqhubekayo kwamadivayisi anikwe amandla we-DC. Ababoniswa ngezansi bayizimiso ezisebenzayo, ukubaluleka nokuthi amadivaysi okuvikela ama-DC Surge avikela kanjani ama-Systems ethu kagesi.

-ZwayoAmadivayisi wokuvikela ama-DC Surge

 

1. Ayini amadivayisi wokuvikela ama-DC Surge?

 

Amadivayisi wokuvikela ukuvikelwa kwama-DC owaziwa kakhulu ngokuthi ama-DC SPD kagesi ahlelwe amadivaysi kagesi ahlelwe ukuqapha ama-appratus anikwe amandla e-DC kanye nezinhlaka ezivela kuma-Swift Electrical Energy Energy Energy Spikes ebangelwa yinqubo yamandla kagesi. Umbani ushaya, ukushintshanisa ukusebenza, ukuphazamiseka kwe-electromagnetic (i-EMI), noma amaphutha okunikeza amandla kubangela izikhala.

 

Umsebenzi oyinhloko wokuvikelwa kwe-DC Surge ulawulwa inani lamanje ledluliswa epanini eliphansi nasekuqedeni amandla ngokweqile ngokuphephile ku-mined. Ngakho-ke kusiza ekuvimbeleni ukulimala okungaba khona kwemishini ebucayi ebandakanya amabhethri, ama-inverters, ama-rexiaiers, neminye imishini ebalulekile ngaphakathi kohlelo lwamandla we-DC.

 

· Ngenqubo yokufaka enobuhle, uzoba sesimweni sokumboza ukulahleka okuningi okungabangelwa izikhala. Izingozi zalezi zikhala ze-voltage zifaka ukuqubuka komlilo, noma izingozi ze-electrocution.

 

2. Ukubaluleka kwamadivayisi wokuvikela ama-DC Surge

 

· Ngenxa yokusetshenziswa kokuvuvukala kwezinhlelo zamandla avuselelekayo njengoba kuphawuliwe ngaphambili, isibonelo; Ama-turbines womoya kanye namaphaneli e-sovovoltaic (PV) elanga. Lezi zinhlelo ngokujwayelekile zikhiqiza amandla we-DC, okudinga ukuvikeleka ngokufanele ekuvezweni kwamandla kagesi okungahleliwe. Lokhu kusize isicelo esiphakeme samadivayisi wokuvikela ukuvikelwa kwe-DC.

 

· Nginojantshi ojwayelekile wokufaka, lokhu kugxila okuqinile okuqinile okuqinile ukufakwa kwesitimela kubalulekile, uyalulekwa ukuthi awusebenzise mahhala. Zonke iziteshi ze-sequeteredwered, okunguhlobo lomgodi omkhulu we-terminal terminal terminal terminal

 

· Ngaphezu kwalokho, kunesidingo sokuvikelwa okusebenzayo kokuhlinzwa njengezisetshenziswa eziningi ze-elekthronikhi, njengezikhungo zedatha, izinhlelo zokuxhumana ngocingo, nezimoto zikagesi, zincike emandleni e-DC. Ama-elekthronikhi abucayi nemishini angalimala ngokungafanele, okuholela esikhathini sokudla okubizayo kanye nezingozi zokuphepha uma ukuklanywa ekuvikelweni.

 

Izimiso Zokusebenza zamadivayisi wokuvikela ama-DC Surge

 

Kubalulekile ukuxhumana ne-interface yomkhiqizo; Lokhu kuzokuvumela ukuthi uqonde umkhiqizo ofanele ongawuthenga. Zhejiang Mulang Electric Co, Ltd. Ikhwalithi YokwakhaDC SPDNge-logo yazo eyingqayizivele, enikezwe amandla yi-MY1-C40 ku-DC1000V nangaphezulu.

 

1. Izakhi zokuvikela eSurge

 

Amadivaysi okuvikela ama-DC Surge aqukethe izakhi ezahlukahlukene ezisebenza ndawonye ukuqondisa kabusha i-Surge yamanje nokuvikela amadivaysi aphansi. Izinto ezibalulekile zifaka;

- Mly 1 modular

- Ama-Metal Oxide Varistors (Movs)

- Amashubhu wokukhipha igesi (GDTS)

- I-Transitent Voltage Supressionas (TVS Diodes)

Umfula

 

a) mly 1 modular

Lo Mvikeli weSurge usetshenziselwa ukuqapha i-surge eholwa ngokukhanyisa nakho okuqhubekayo kwama-svervoltage. Isiza ukukhulula amandla amakhulu e-Line Porser emhlabeni asemhlabeni okusemhlabathini ukunciphisa amandla aphezulu.

 

b) Izinhlobo ze-Metal Oxide Varistors:

I-Movs ayilawulwa kabanzi ye-Voltage-ancike ekunciphiseni i-voltage spikes ngokunikeza umkhondo ohlanganyelwe ophansi wamandla angeziwe. Baphambanisa ukuhlukunyezwa kwamanje nokuphazamisa ngokuphephile emhlabathini, kuvikela ama-applatus ahlobene.

 

c) Amashubhu wokukhipha igesi:

Ama-GDTs angamadivayisi avalwe ngamakhambi agcwele amagesi avila ama-ionize lapho evezwa amandla aphezulu. Bakha umzila ophethe amandla okuhlinza amandla, ukuqinisa amandla amandla futhi abuyise amandla kude nemishini ecashile.

 

d) Ama-voltage voltage Suppressional Disoode:

Ama-TV ama-Diodes angama-TV amadivaysi e-semiconductor aklanyelwe ukuphazamisa amandla okudlula kude ne-elekthronikhi entekenteke. Bane-voltages ephansi yokuqhekeka futhi baphendule ngokushesha kuma-voltage spikes, bagweme ngokweqile emhlabathini.

 

e) fuses:

I-FUSE AST njenge-Shieting Expedients ngokufaka ukugeleza kwe-flow engadingekile yamanje. Ziyizindlela zomhlatshelo ezinamafutha lapho kuhlangana amandla adlula ivolumu yakhe ekalwe, kuvimbela ukulimala okwengeziwe kwizinto ezixhunyiwe.

 

Izidingo Zomsebenzisi

Kunemihlahlandlela yomsebenzisi okufanele uyigeleze ngemuva kokuthenga lezi zi-spds ze-DC ukuqapha izinto zakho zikagesi. Lokhu kufaka phakathi;

- Sebenzisa phakathi kuka-50hz no-60hz ac

- Faka ngaphansi kwe-2000m ngaphezulu kwezinga lolwandle

- Ukusebenza kwemvelo lokushisa -40, +80

- Nge-MLY1, iVoltage ye-terminal akufanele yeqe inani layo eliphakeme eliqhubekayo

- Ukufakwa kwesitimela okujwayelekile kwe-35mm

 

Inqubo Yokusebenza

 

Lapho kwenzeka i-voltage surge, idivaysi yokuvikela i-DC Surge ithola amandla athile futhi isebenze inqubo yokuvikelwa. I-Movels, ama-GDTS, nama-TVs diodes ahlinzeka izindlela zokumelana okuphansi zokwehla kwamanje, zikuphambukisa ngokuphepha emhlabathini.

 

AmaFuses, ngakolunye uhlangothi, yenza njengomugqa wokugcina wokuzivikela ngokuphazamisa ukugeleza kwamanje uma kudlula isilinganiso esiphezulu sedivayisi. Ngokunciphisa ngokwanele izikhala ze-voltage, ama-DC spd aqinisekisa ukuthi imishini ephansi ithola ukuhanjiswa kwamandla okuzinzile nokuvikelekile.

 

Izinzuzo ze-DC SPD

 

1. Ukuvikelwa Kwemishini:

Inzuzo enkulu yokusebenzisa amadivaysi e-DC Surge Diraction Desication ukulondolozwa kwemishini exhunyiwe kusuka ku-Voltage Surges. Ukuphila kwemishini kunwetshiwe ngenxa yokuvimbela umonakalo obizayo kanye nesikhathi sokuphumula ngokuphambukiswa kwamandla aphezulu kude.

 

2. Isiqinisekiso Sokuphepha:

I-Voltage Sugtage Sugtage ingabeka izingozi ezibalulekile zokuphepha, ikakhulukazi ezindaweni ezisengozini enkulu njengezikhungo zedatha noma iziteshi zokushaja kwezimoto zikagesi. I-DC SPDS inikezela ngongqikithi wokuphepha ongezwe ngokunciphisa amathuba okuba izingozi zomlilo, ukushaqeka kukagesi, noma ukwehluleka kwemishini.

 

3. Ukusebenza okuthembekile:

Izinhlelo zikagesi zingenza ngokwethembekile ngamadivayisi wokuvikela ama-DC e-Domicile. Ingozi encishisiwe yokuhluleka okungazelelwe noma ukungasebenzi kahle kuqinisekisa ukuhlinzekwa kwamandla okungaphazanyiswa, okuholela ekukhiqizweni okuthuthukile nokwaneliseka kwamakhasimende.

Ukugcina

 

Emhlabeni wamanje lapho amadivaysi kagesi nezinhlelo zamandla avuselelekayo zibambe iqhaza elibalulekile ezimpilweni zethu zokusivikela ezivela kumandla kagesi akwenziwayo.Amadivayisi wokuvikela ama-DC SurgeKhonza njengezakhi ezibucayi ekuvikeleni imishini enamandla we-DC kanye nezinhlelo kusuka kumicimbi ye-voltage yesikhashana. Kubalulekile ukuqonda izimiso ezisebenzayo, kanye nezinzuzo abazinikezayo njengoba lokhu kungaqinisekisa ukuqondisa okuthembekile futhi okuhlala isikhathi eside kwezimpilo zethu kanye nokusetha kukagesi. Cabanga ukutshala imali kuma-DC SPD ukunciphisa ubungozi obuhambisana nokugqekeza kwamandla kagesi futhi ulondoloze izimpahla zethu ezibalulekile ezifana nohlelo lwe-PV ophahleni lwakho noma inethiwekhi ebucayi yezokuxhumana.
