Iyini Idivayisi Yokuvikela Ukwanda Kohlobo 1+2 Ehlanganisiwe?

Kwingqalasizinda kagesi yesimanje, lawa madivayisi avame ukufakwa emnyango wesevisi noma ebhodini lokusabalalisa eliyinhloko ukuvikela yonke indawo uhlelo lokuvikela ukukhuphuka kukagesi.

Ukuqonda ubudlelwano phakathi Idivayisi yokuvikela ukukhuphuka kohlobo 1+2 vs Uhlobo 2 kubalulekile lapho kuklanywa ukuvikelwa kokukhuphuka okuhlanganisiwe kumanethiwekhi kagesi ezimboni nawezentengiselwano.

Ngokungafani nendinganiso Idivayisi yokuvikela ukukhuphuka kohlobo lwesibili, okuvikela kakhulu ekukhanyeni okungaqondile kanye nokushintshashintsha kwamandla, Idivayisi yokuvikela ukukhuphuka kohlobo 1+2 yakhelwe ukuphatha imifudlana yombani enamandla aphezulu ngenkathi futhi inciphisa i-overvoltage engezansi komfula.

Izinhlelo eziningi zokuvikela ukungena kwezinsizakalo ziyahlangana Izivikeli zokugibela isitimela ze-DIN eyenzelwe ngqo ikhono eliphezulu lokukhipha kanye nokuhambisana nemithetho Idivayisi yokuvikela ukukhuphuka kwe-IEC 61643-11 amazinga.

Izibonelo zalobu buchwepheshe bokuvikela zingatholakala ku- Izixazululo ze-SPD zohlobo 1+2 eyenzelwe izindawo zokusabalalisa amandla ezimbonini.

I-SPD yohlobo lwe-1+2 isebenza kanjani njenge-Lightning Current Arrester?

A Uhlobo 1+2 oluhlanganisiwe lwe-SPD isebenza njenge isibambi samandla ombani ngokuphambukisa ngokuphephile imisinga enamandla aphezulu evela ezenzakalweni zombani iye ohlelweni lokumisa umhlaba.

Lawa madivayisi aklanyelwe ukumelana nezindinganiso ezijwayelekile Ifomu legagasi lokukhanya elingu-10/350 μs, okumelela umbane oqondile ongena kunethiwekhi kagesi.

Indlela Yokukhipha Ugesi Ngombani

Ngesikhathi sokushaya kombani noma ukuqhuma okukhulu okubangelwa yi- idivayisi yokuvikela umbani isebenza ngokushesha izakhi zokuvikela zangaphakathi ezifana nalezi:

• i-varistors ye-metal oxide (MOV)

• amapayipi okukhipha igesi (i-GDT)

• izakhiwo zesikhala senhlansi

Lezi zingxenye ziqhuba amandla okunyuka komhlaba ngenkathi zinciphisa i-voltage efinyelela izifunda ezingezansi komfula.

Ezinhlelweni eziklanywe ngokwe- Izindawo zokuvikela umbani ze-LPZ, Ama-SPD ohlobo 1+2 avame ukufakwa ekushintsheni phakathi kwe-LPZ 0 ne-LPZ 1.

Lokhu kubekwa kuvimbela ukwanda kwamandla aphezulu ukuthi kungasabalali ngokujulile ekufakweni kukagesi.

Ukuze uthole ukuqhathanisa okuningiliziwe kobuchwepheshe okuchazayo Idivayisi yokuvikela ukukhuphuka kohlobo 1+2 vs Uhlobo 2, ungabheka umhlahlandlela wobunjiniyela lapha:

Yiziphi Izinhlelo Zokusebenza Ezidinga Ama-SPD Ohlobo 1+2 Ahlanganisiwe?

A Uhlobo 1+2 oluhlanganisiwe lwe-SPD isetshenziswa kabanzi ezinhlelweni zamandla lapho kudingeka khona kokubili ukuvikelwa kwamanje kombani kanye nomkhawulo wokuphakama.

Izicelo Ezijwayelekile

Ukufakwa okuvamile kufaka phakathi:

• amaphaneli okungena ezinsizakalo ezakhiweni zezentengiselwano

• izinhlelo zokusabalalisa amandla ezimboni

• izinhlelo zamandla ze-photovoltaic

• izikhungo zokuxhumana

• amakamelo emishini yengqalasizinda

Lezi zindawo zidinga ukuqina ukuvikelwa kokunyuka kwebhodi lokusabalalisa eliyinhloko ngoba imisinga yombani engena ngezintambo zikagesi ingabangela umonakalo omkhulu emishinini.

Ukufakwa kwezimboni kuvame ukusebenzisa uhlelo lokuvikela ukukhuphuka kwe-cascading, lapho kufakwa khona izinhlobo eziningi ze-SPD emazingeni ahlukene enethiwekhi yamandla.

Isakhiwo Esijwayelekile Sokuxhumanisa i-SPD

Lesi sakhiwo siqinisekisa ukuthi amandla okukhuphuka ancishiswa kancane kancane kulo lonke uhlelo lokuvikela ukukhuphuka kukagesi, ukuthuthukisa ukuthembeka kwemishini kanye nokuphepha kokusebenza.

Ungayikhetha Kanjani I-DIN Rail Type 1+2 Surge Protector?

Ukukhetha okulungile Isivikelo sokukhuphuka kwesitimela se-DIN kudinga ukuhlola kokubili izici zesistimu kagesi kanye nezimo zemvelo.

1. Hlola i-System Voltage kanye nokucushwa kwe-Earthing

I-SPD kumele ifane nelungiselelo lokusekela uhlelo.

Ukucushwa okuvamile kufaka phakathi:

• Uhlelo lokuvikela ukukhuphuka kwe-TT

• Uhlelo lokuvikela ukukhuphuka kwe-TN-S

Uhlelo ngalunye ludinga ukucushwa kwezintambo ezithile ze-SPD ukuqinisekisa ukuthi amaza okushisa akhishwa kahle emhlabeni.

2. Hlola Isilinganiso Samanje Sombani

Okwe Uhlobo 1+2 oluhlanganisiwe lwe-SPD, amapharamitha okusebenza abalulekile afaka:

• isilinganiso samanje se-impulse (Iimp)

• ukukhishwa kwamanje okujwayelekile (Ngaphakathi)

• ukukhishwa kwamandla aphezulu (Imax)

Kudingeka amandla aphezulu okusakaza umbani ezindaweni ezivame ukuba nombani noma ezifakwe ngezinhlelo zokuvikela umbani zangaphandle.

3. Qinisekisa ukuthi ihambisana nezindinganiso ze-IEC

Okuthembekile idivayisi yokuvikela ukukhuphuka kwezimboni kufanele ihambisane Idivayisi yokuvikela ukukhuphuka kwe-IEC 61643-11 izidingo, ezichaza:

• ama-waveform okuhlolwa kokukhuphuka

• ukuhlukaniswa kwedivayisi

• ukusebenza kokuphepha

Ukuthobela imithetho kuqinisekisa ukuhambisana nemithethonqubo yokuphepha kagesi yomhlaba wonke.

4. Cabanga Ngesikhala Sokufaka Nokulungisa

Okwesimanje kakhulu Izivikeli zokugibela isitimela ze-DIN amadivayisi e-modular aklanyelwe ukufakwa kumaphaneli okusabalalisa kagesi ajwayelekile.

Ukukhetha i-SPD encane kodwa enamandla amakhulu kwenza kube lula ukuhlanganiswa kuma-switchboard ezimboni kanye namakhabhinethi okulawula.

Izinsiza ezengeziwe zokuklama ukuvikelwa kokukhuphuka ziyatholakala ngokusebenzisa Izixazululo zobunjiniyela bokuvikela ukukhuphuka kwe-Leikexing, kuyilapho imibuzo eqondene nephrojekthi ingathunyelwa nge ukubonisana kobuchwepheshe.

Isiphetho

A Uhlobo 1+2 oluhlanganisiwe lwe-SPD idlala indima ebalulekile ekuvikeleni ingqalasizinda kagesi kokubili emifuleni yokukhanya kanye nokushintshashintsha kwamandla kagesi.

Uma uqhathanisa Idivayisi yokuvikela ukukhuphuka kohlobo 1+2 vs Uhlobo 2, umehluko oyinhloko usemandleni okuphatha umbane wamandla ombani kanye nendawo yokufaka ngaphakathi kohlelo lokuvikela ukukhuphuka.

Ngokuhlanganisa Amadivayisi okuvikela ukukhuphuka kohlobo 1+2 kumaphaneli okungena kwesevisi futhi uwahlanganise nalawo angaphansi komfula Amadivayisi okuvikela ukukhuphuka kohlobo lwesibili, onjiniyela bangakha i- uhlelo lokuvikela ukukhuphuka kwe-cascading evikela imishini yezimboni kanye nokufakwa kukagesi.

Imibuzo Evame Ukubuzwa

Iyini i-SPD yohlobo 1+2 ehlanganisiwe?

I-Type 1+2 SPD ehlanganisiwe iyithuluzi lokuvikela ukukhuphuka elihlinzeka kokubili amandla okukhipha umbane wamanje kanye nokuvikelwa kwe-overvoltage ngaphakathi kweyunithi eyodwa.

Kufanele ifakwe kuphi idivayisi yokuvikela ukukhuphuka kohlobo 1+2?

Ngokuvamile ifakwa emnyango wesevisi noma ebhodini lokusabalalisa eliyinhloko ukuvikela lonke uhlelo lukagesi ekukhuphukeni kombani.

Uyini umehluko phakathi kwe-Type 1+2 SPD kanye ne-Type 2 SPD?

Ama-SPD ohlobo lwe-1+2 angaphatha imisinga yokukhanya eqondile, kuyilapho ama-SPD ohlobo lwe-2 evikela kakhulu ekushintsheni kokukhanya kanye nemiphumela yokukhanya engaqondile.

Ingabe izivikelo ze-DIN rail surge zifanelekile ezinhlelweni zezimboni?

Yebo. Amadivayisi amaningi okuvikela ukukhuphuka kwezimboni aklanywe njengezivikelo zokukhuphuka kwesitimela ze-DIN zokufakwa kumaphaneli kagesi.

Ingabe ama-SPD ohlobo 1+2 ahambisana nezindinganiso ze-IEC?

Iningi lamadivayisi okuvikela ukukhuphuka kohlobo 1+2 asezingeni eliphezulu ahambisana nezindinganiso ze-IEC 61643-11 zamadivayisi okuvikela ukukhuphuka kohlobo.
