Izixhobo zoKhuseleko lwe-DC Surge: Ukukhusela iiNkqubo zakho zoMbane

Kule mihla yangoku, itekhnoloji iye yaba phambili ebomini bethu kwaye ukukhusela izixhobo zethu kunye neenkqubo zombane kubaluleke kakhulu. Uninzi lwabantu lucinga ngezixhobo ezifakwe kwiintambo zombane ze-AC xa kufikwa kukhuseleko lotyando, kodwa imfuno yezixhobo zokhuseleko ze-DC ziye zanda kakhulu kule minyaka idlulileyo. Oku kungenxa yokunyuka kweenkqubo zamandla ahlaziyekayo kunye nokwanda okuqhubekayo kwezixhobo eziqhutywa yi-DC. Oku kuboniswe ngezantsi yimithetho-siseko yokusebenza, ukubaluleka kunye nendlela izixhobo zokhuseleko ze-DC ezikhusela umbane wethu.

UkuqondaIzixhobo zoKhuseleko lwe-DC Surge

 

1. Yintoni i-DC Surge Protection Devices?

 

· Izixhobo zokhuselo zeDC ezidla ngokubizwa ngokuba zii-DC SPDs zizixhobo zombane ezilungiselelwe kwangaphambili ukugada izixhobo ezisebenza ngamandla e-DC kunye nezakhiwo ezisuka kumandla ombane akhawulezayo abangelwa ziinkqubo zamandla ombane okwethutyana. Umbane ubetha, ukusebenza kokutshintsha, ukuphazamiseka kwe-electromagnetic (EMI), okanye iziphene zobonelelo lwamandla zibangela izikhonkwane.

 

· Owona msebenzi uphambili we-DC Surge Protector kukulawula umthamo wangoku ogqithwayo ukuya kwi-paraphernalia esezantsi kunye nokuphambukisa amandla agqithisileyo ngokukhuselekileyo ukuya kwimingxuma. Yiyo loo nto inceda ekuthinteleni umonakalo onokwenzeka kwizixhobo ezibuthathaka ezibandakanya iibhetri, ii-inverters, izihlaziyi, kunye nabanye oomatshini ababalulekileyo ngaphakathi kwenkqubo yamandla yeDC.

 

· Ngenkqubo yofakelo endilisekileyo, uya kuba kwindawo yokugquma iilahleko ezininzi ezinokubangelwa zizikhonkwane. Iingozi zezi spikes zombane ziquka ukuqhambuka komlilo, okanye iingozi zombane.

 

2. Ukubaluleka kwezixhobo zoKhuseleko lwe-DC Surge

 

· Ngenxa yokudumba kokusetyenziswa kweenkqubo zamandla ahlaziyekayo njengoko bekutshiwo ngaphambili, umzekelo; ii-injini zomoya kunye neepaneli ze-solar photovoltaic (PV). Ezi nkqubo zivelisa amandla e-DC, efuna ukukhuselwa ngokufanelekileyo ekuphumeni kwamandla ombane angenamkhethe. Oku kuye kwanceda kwisicelo esiphezulu sezixhobo zokukhusela i-DC.

 

· Ngomzila kaloliwe onyukayo osemgangathweni, eli qhosha liqinileyo lofakelo lukaloliwe oluncamathelayo lubalulekile, uyacetyiswa ukuba ulisebenzise ngaphandle kokukhathazeka. Yonke i-terminal ehleliweyo, engumngxuma omkhulu wohlobo lwe-terminal ye-terminal i-wireing iyaqina kwaye ifanelekile.

 

· Ngaphezu koko, kukho imfuneko yokhuseleko lokutya okusebenzayo njengezixhobo zombane ezininzi, ezinje ngamaziko edatha, iinkqubo zonxibelelwano, kunye nezithuthi zombane, zixhomekeke kumandla eDC. Ii-elektronikhi ezinovakalelo kunye nezixhobo zinokonakala ngendlela engenakulungiseka, nto leyo ekhokelela kwixesha elibiza imali eninzi kunye neengozi ezinokuthi zibe kho zokhuseleko ukuba ukhuseleko olo lungonelanga.

 

Imigaqo esebenzayo ye-DC Surge Protection Devices

 

Kubalulekile ukusebenzisana nojongano lwemveliso; oku kuyakwenza ukuba uqonde imveliso efanelekileyo onokuyithenga. Zhejiang Mulang Electric Co., Ltd. Umgangatho wokwenziwaDC SPDskunye nelogo yabo eyahlukileyo, inikwa amandla yi-MLY1-C40 kwi-DC1000V nangaphezulu.

 

1. Amacandelo oKhuseleko lweSurgery

 

Izixhobo zokukhusela i-DC surge ziqulathe amacandelo ahlukeneyo asebenza kunye ukuqondisa kwakhona i-surge yangoku kunye nokukhusela izixhobo ezisezantsi. Amacandelo aphambili abandakanya;

- MLY 1 imodyuli

-Metal oxide varistors (MOVs)

-Iityhubhu zokukhupha igesi (GDTs)

-Iidiodi zokucutha amandla ombane (ii-TVS diode)

Iifusi

 

a) MLY 1 imodyuli

Lo mkhuseli wotyando usetyenziselwa ukugada i-surgery ekhokelwa kukukhanya kunye nokugqithisa okwethutyana. Inceda ukukhulula amandla amakhulu kwintambo yamandla ukuya eMhlabeni osemhlabeni ukukhawulela amandla angaphezulu.

 

b) Iivaristors zeMetal oxide:

Ii-MOVs zizilawuli ezingaxhomekekanga kumbane wombane ezibuyisela kwi-voltage spikes ngokunika umkhondo ophantsi wokujongana namandla ongezelelweyo. Zithi jize umsinga wokutyabula kwaye ziwuphambukise ngokukhuselekileyo emhlabeni, zikhusela izixhobo ezinxulumeneyo.

 

c) Imibhobho yokukhupha igesi:

Ii-GDT zizixhobo ezitywinwe ngokwe-hermetically ezizaliswe ziigesi ezinobuvila ezithi i-ionize xa zivezwe kumbane ophezulu. Benza indlela yokuhambisa amandla otyando, baqinise ngokufanelekileyo amandla kunye nokufunda amandla kude nezixhobo ezifihlakeleyo.

 

d) IiDiode zokuNcitshiswa koMbane woMbane:

I-TVS diode zizixhobo ze-semiconductor ezenzelwe ukuphazamisa amandla adlulayo kude ne-electronics eethe-ethe. Bane-voltages ephantsi yokuqhekeka kwaye baphendule ngokukhawuleza kwi-voltage spikes, bekhupha umsinga ogqithisileyo emhlabeni.

 

e) Iifayisi:

Iifusi zisebenza njengezixhobo ezikhuselayo ngokungenelela ukuhamba komsinga ongeyomfuneko. Ziindlela zokuzincama ezinyibilikisayo xa ukunyuka kwamandla kugqitha umthamo wazo obekiweyo, nto leyo enqanda umonakalo ongakumbi kwisixhobo esidityanisiweyo.

 

Iimfuno zabasebenzisi

Kukho izikhokelo zomsebenzisi ofanele ukuhamba emva kokuthenga ezi DC SPDs ukugada izinto zakho zombane. Ezi ziquka;

-Yisebenzise phakathi kwe-50Hz kunye ne-60Hz AC

-Yifake ngaphantsi kwe-2000m ngaphezu komphakamo wolwandle

- Ubushushu bume okusebenzayo -40, +80

Nge-MLY1, i-voltage ye-terminal akufuneki igqithe ubuninzi bayo iqhubeka nokusebenza i-voltage

- Ufakelo lukaloliwe oluqhelekileyo lwe-35mm

 

Inkqubo yokusebenza

 

Xa utyando lombane lusenzeka, isixhobo sokukhusela i-DC sibona umbane ogqithileyo kwaye sivule indlela yokukhusela. Ii-MOVs, i-GDTs, kunye ne-TVS diode zibonelela ngeendlela eziphantsi zokumelana nokunyuka kwangoku, ukuphambukisa ngokukhuselekileyo emhlabeni.

 

Iifuse, ngakolunye uhlangothi, zisebenza njengomgca wokugqibela wokukhusela ngokuphazamisa ukuhamba kwangoku ukuba kudlula umlinganiselo ophezulu wesixhobo. Ngokunciphisa ngokwaneleyo i-voltage spikes, ii-DC SPDs ziqinisekisa ukuba izixhobo ezisezantsi zifumana unikezelo lwamandla oluzinzileyo nolukhuselweyo.

 

Izibonelelo zee-DC SPDs

 

1. Ukhuseleko lweZixhobo:

Olona ncedo luphambili lokusebenzisa izixhobo ze-DC surge fortification kugcino lwesixhobo esiqhagamshelwe ukusuka ekunyukeni kwamandla ombane. Ubomi bezixhobo bandiswa ngenxa yothintelo lomonakalo obiza imali eninzi kunye nexesha lokuphumla ngokuphambukiswa kwamandla agqithileyo kude.

 

2. Isiqinisekiso soKhuseleko:

Ukunyuka kwamandla ombane kunokubeka imingcipheko ebalulekileyo yokhuseleko, ngakumbi kwiindawo ezinomngcipheko ophezulu njengamaziko edatha okanye izikhululo zokutshaja iimoto zombane. I-DC SPDs ibonelela umaleko owongezelelweyo wokhuseleko ngokunciphisa ukuba nokwenzeka kweengozi zomlilo, ukothuka kombane, okanye ukusilela kwezixhobo.

 

3. Imisebenzi ethembekileyo:

Iisistim zombane zinokwenza ngokuthembekileyo ngakumbi ngezixhobo zokhuselo lwe-DC kwi-domicile. Umngcipheko oncitshisiweyo wokusilela ngequbuliso okanye ukungasebenzi kakuhle kuqinisekisa unikezelo lwamandla olungaphazamisekiyo, olukhokelela ekuphuculweni kwemveliso kunye nokwaneliseka kwabathengi.

Ukuqukumbela

 

Kwihlabathi langoku apho izixhobo zombane kunye neenkqubo zamandla avuselelekayo zidlale indima ebalulekileyo kubomi bethu bokusikhusela kwiingozi zokunyuka kwamandla ombane azinakulinganiswa.Izixhobo zokukhusela i-DCzisebenza njengamacandelo abalulekileyo ekukhuseleni izixhobo ezisebenza ngamandla e-DC kunye neenkqubo kwimisitho yamandla ombane adlulayo. Kubalulekile ukuqonda imigaqo yokusebenza, kunye neenzuzo abazinikezelayo njengoko oku kunokuqinisekisa ukulawulwa okuthembekileyo kunye nexesha elide lobomi bethu kunye nokusekwa kombane. Cinga ngokwenza utyalo-mali kwii-DC SPDs ukunciphisa imingcipheko eyayanyaniswa nokunyuka kwamandla ombane kunye nokugcina izinto zethu zexabiso ezifana nenkqubo yePV kuphahla lwakho okanye inethiwekhi ebalulekileyo yonxibelelwano.
