Ingabe Umehluko Phakathi Kwamadivayisi Okuvikela Ukwanda Kohlobo 1+2 Nohlobo 2?

Ukuqonda Idivayisi yokuvikela ukukhuphuka kohlobo 1+2 vs Uhlobo 2 ukuhlukaniswa kubalulekile lapho kuklanywa indlela ephumelelayo uhlelo lokuvikela ukukhuphuka kukagesiIzinhlobo ezahlukene zamadivayisi okuvikela ukukhuphuka (i-SPD) zenzelwe ukusingatha izimo ezithile zokukhuphuka, ikakhulukazi imisinga yokuphambuka kombani kanye nezinguquko zokushintsha.

Kwingqalasizinda yokusabalalisa ugesi yesimanje, onjiniyela bavame ukusebenzisa Uhlobo 1+2 oluhlanganisiwe lwe-SPD emnyango wenkonzo ukuvikela emisinga yombani enamandla aphezulu, ngenkathi Amadivayisi okuvikela ukukhuphuka kohlobo lwesibili zivame ukufakwa kumaphaneli okusabalalisa angezansi komfula.

Izakhiwo zezimboni, izakhiwo zezentengiselwano, kanye nezinhlelo zamandla avuselelekayo zivame ukuhlanganisa zombili izinhlobo zamadivayisi njengengxenye ye- uhlelo lokuvikela ukukhuphuka kwe-cascading ukuqinisekisa ukuvikelwa okuhlelekile kuyo yonke inethiwekhi kagesi.

Izibonelo zezixazululo zokuvikela ezinamandla aphezulu zingabonakala ku- Imiklamo yedivayisi yokuvikela ukukhuphuka kohlobo 1+2 isetshenziselwa ukufakwa kweminyango yesevisi.

Ama-SPD ohlobo lwe-1+2 ahlanganisiwe aphatha kanjani umbani kanye nokushintshashintsha?

A Uhlobo 1+2 oluhlanganisiwe lwe-SPD ihlanganisa imisebenzi emibili yokuvikela kudivayisi eyodwa:

• ikhono lokukhipha umbane wamanje (Uhlobo 1)

• ukukhawulelwa kwe-overvoltage kusuka ekushintsheni kwe-surges (Uhlobo 2)

Le nhlanganisela ivumela idivayisi ukuthi isebenze njenge- idivayisi yokuvikela umbani ikwazi ukuqhuba ngokuphephile imisinga emikhulu yokuphambuka ebangelwa ukushaya kombani okuqondile noma okuseduze.

Ukuvikelwa Kwamanje Kombani

Ngesikhathi somcimbi wombani, isibambi samandla ombani kumele iphathe imisinga yokushukuma echazwe ukuhlolwa kwe-waveform engu-10/350 μs esetshenziswa ku Idivayisi yokuvikela ukukhuphuka kwe-IEC 61643-11 amazinga.

Ama-SPD ohlobo lwe-1+2 angakhipha la mandla aphezulu ngaphandle kokulimaza imishini engezansi komfula.

Ukushintsha Ukuvikelwa Kokukhuphuka

Ukushintshashintsha kokushintsha kuvela ku:

• ukushintsha i-transformer

• imicimbi yokuqala/yokuma kwezimoto

• ukushintsha kwebhange le-capacitor

• ukuphazamiseka kwegridi

Isigaba sokuvikela sohlobo 2 esihlanganisiwe sinciphisa i-voltage eseleyo, siqinisekisa ukuthi imishini ebucayi ithola amandla azinzile.

Ngenxa yalesi sizathu, abaningi banamuhla amadivayisi okuvikela ukukhuphuka kwezimboni hlanganisa umbani kanye nokuvikela ukukhuphuka komoya kumojuli eyodwa.

Kuphi lapho kufakwa khona ama-SPD ohlobo 1+2 kanye nohlobo 2 ku-Power Systems?

Ukubekwa kwe-SPD okulungile kunqunywa yi- Izindawo zokuvikela umbani ze-LPZ umqondo osetshenziswa kubunjiniyela bokuvikela ukukhuphuka.

Indawo ngayinye imelela izinga elihlukile lokuchayeka kombani.

Ukufakwa kwe-SPD yohlobo 1+2

A Idivayisi yokuvikela ukukhuphuka kohlobo 1+2 ivame ukufakwa ku:

• umnyango wesevisi yesakhiwo

• ibhodi lokusabalalisa eliyinhloko

• amaphaneli okufaka ijeneretha

• amaphaneli okuhlanganisa i-AC e-photovoltaic

Lawa madivayisi ahlinzeka ukuvikelwa kokunyuka kwebhodi lokusabalalisa eliyinhloko ngokumelene nemizwa yombani enamandla aphezulu engena ohlelweni lukagesi.

Ukufakwa kwe-SPD yohlobo lwesibili

A Idivayisi yokuvikela ukukhuphuka kohlobo lwesibili kuvame ukufakwa:

• emabhodini okusabalalisa amancane

• amaphaneli emishini yangaphakathi

• imithwalo kagesi ebucayi eseduze

Lawa madivayisi avame ukusetshenziswa njenge Izivikeli zokugibela isitimela ze-DIN amakhabethe okulawula afakwe ngaphakathi noma amaphaneli okusabalalisa.

Isakhiwo Esijwayelekile Sokuxhumanisa i-SPD

Lolu hlelo oluhlelekile lwakha uhlelo lokuvikela ukukhuphuka kwe-cascading, ukuqinisekisa ukuthi amandla okwanda ancishiswa kancane kancane kuyo yonke inethiwekhi kagesi.

Ungakhetha Kanjani Phakathi Kwamadivayisi Okuvikela Ukwanda Kohlobo 1+2 Nohlobo 2?

Ukukhetha idivayisi efanele ku Idivayisi yokuvikela ukukhuphuka kohlobo 1+2 vs Uhlobo 2 Ukuqhathanisa kuncike ekucushweni kwesistimu kanye nokuvezwa kombani.

1. Hlola Ukuchayeka Kombani

Izakhiwo ezisezindaweni ezivame ukuba nombani noma ezihlonyiswe ngezinhlelo zokuvikela umbani zangaphandle ngokuvamile zidinga Uhlobo 1+2 oluhlanganisiwe lwe-SPD amadivayisi emnyango wamandla.

Lawa madivayisi aphatha imisinga ephezulu yokucindezela ngaphambi kokuba ama-surge asakazeke ohlelweni.

2. Cabanga Ngokucushwa Kwesistimu Yomhlaba

Izinhlelo ezahlukene zokumba umhlaba zithinta ukukhethwa kwe-SPD.

Ukucushwa okuvamile kufaka phakathi:

• Uhlelo lokuvikela ukukhuphuka kwe-TT

• Uhlelo lokuvikela ukukhuphuka kwe-TN-S

Isakhiwo ngasinye somhlaba sithonya indlela imisinga yokukhuphuka kwamanzi eqondiswa ngayo emhlabeni.

Ukuhlanganiswa okufanele kwe-SPD kuqinisekisa ukuhambisana nemithetho Idivayisi yokuvikela ukukhuphuka kwe-IEC 61643-11 izidingo.

3. Hlola i-Voltage Yesistimu kanye Nokuzwela Komthwalo

Imishini kagesi ebucayi efana nalokhu:

• Izilawuli ze-PLC

• izinhlelo zokwenza izinto ngokuzenzakalela kwezimboni

• Ingqalasizinda ye-IT

• imishini yokuxhumana

ngokuvamile kudinga ukwehla komfula Amadivayisi okuvikela ukukhuphuka kohlobo lwesibili ukuze kuncishiswe amandla kagesi ngendlela eqondile.

Lawa madivayisi ahlinzeka ngesivikelo esengeziwe ngaphakathi kobubanzi uhlelo lokuvikela ukukhuphuka kukagesi.

4. Cabanga ngobulula bokufaka kanye nesikhala

Ezindaweni eziningi zesimanje, onjiniyela bakhetha Ama-SPD ohlobo 1+2 ahlanganisiwe ngoba zinciphisa ubunzima bokufaka ngokuhlanganisa amazinga amabili okuvikela kudivayisi eyodwa.

Izixazululo zezinga lezimboni zingahlolwa ngokusebenzisa izinsiza zobunjiniyela bokuvikela ukukhuphuka noma ngokuxhumana nochwepheshe bokuvikela ukukhuphuka kwe-surge ngokusebenzisa ukubonisana kobuchwepheshe.

Isiphetho

Ukuqonda Idivayisi yokuvikela ukukhuphuka kohlobo 1+2 vs Uhlobo 2 umehluko ubalulekile lapho kuklanywa isu lokuvikela ukukhuphuka okuthembekile.

• Uhlobo lwe-1+2 SPDs vikela emifuleni enamandla amakhulu ombani kanye nokushintshashintsha komoya emnyango wesevisi.

• Uhlobo lwesibili lwe-SPD hlinzeka ngesivikelo sesibili ngaphakathi kwamaphaneli okusabalalisa kanye namasekethe emishini.

Uma kuhlanganiswe kusakhiwo esihlanganisiwe esisekelwe ku- Izindawo zokuvikela umbani ze-LPZ, lawa madivayisi akha indlela ephumelelayo uhlelo lokuvikela ukukhuphuka kwe-cascading okuvikela ingqalasizinda kagesi kanye nemishini ebucayi.

Imibuzo Evame Ukubuzwa

Uyini umehluko phakathi kwamadivayisi okuvikela ukukhuphuka kohlobo 1+2 kanye nohlobo 2?

Amadivayisi okuvikela ukukhuphuka kohlobo 1+2 angaphatha kokubili imisinga yokuphambuka kombani kanye nokukhuphuka kokushintsha, kuyilapho amadivayisi ohlobo 2 enzelwe ikakhulukazi ukuvikela ekukhuphukeni kokushintsha kanye nemiphumela yombani ongaqondile.

Kufanele ifakwe kuphi i-Type 1+2 SPD?

Ama-SPD ohlobo 1+2 avame ukufakwa emnyango wesevisi noma ebhodini lokusabalalisa eliyinhloko ukuze ahlinzeke ngokuvikelwa kokugeleza okuyinhloko.

Iyini uhlelo lokuvikela ukukhuphuka kwe-cascading?

Uhlelo lokuvikela ukukhuphuka kwe-cascading lusebenzisa izinhlobo eziningi ze-SPD ezifakwe emazingeni ahlukene enethiwekhi kagesi ukuze lunciphise kancane kancane amandla okukhuphuka kwe-surge.

Ingabe ama-SPD ohlobo lwesibili anele ukuvikela umbani?

Ama-SPD ohlobo lwesibili kuphela awaklanyelwe ukuphatha imisinga yokukhanya eqondile. Izinhlelo ezivezwe embaneni ngokuvamile zidinga amadivayisi ohlobo 1 noma ahlanganisiwe ohlobo 1+2.

Ingabe izivikeli ze-DIN rail surge ziyasekela izinhlelo zokusebenza zezimboni?

Yebo. Amadivayisi amaningi okuvikela ukukhuphuka kwezimboni aklanywe njengezivikelo zokukhuphuka kwesitimela se-DIN ukuze kube lula ukuwafaka ngaphakathi kwamaphaneli okusabalalisa.
