Idivayisi yokuvikela ukukhuphuka kwe-surge engcono kakhulu yamaphaneli elanga | LKX-T1T2-DC

I Idivayisi Evikelayo Yohlobo 1+2 SPD Surge 20–40kA 1200V DC 2-Pole (LKX-T1T2-DC) uletha ukuvikelwa kokuqhuma kwe-Class I + Class II okuhlanganisiwe kwezinhlelo zamandla ze-DC kanye ne-photovoltaic ezinamandla aphezulu, ezihlinzeka ngokuzivikela okuqinile ngokumelene imisinga yombani eqondile, ukukhuphuka okubangelwayo, kanye nokweqisa kwamandla kagesi okudlulayo. Yaklanywa nge Isekethe yokuvikela ye-MOV hybrid enamandla aphezulu ye-GDT +, inikeza amandla aphezulu okushaya kombani, impendulo esheshayo kakhulu, isivikelo sokunqanyulwa kokushisa, kanye nokusebenza okuzinzile kwesikhathi eside kwe ama-solar PV arrays, amabhokisi okuhlanganisa, ama-central/string inverters, izitshalo ze-PV ezinkulu, izinhlelo zokugcina amabhethri, kanye namanethiwekhi okusabalalisa angu-1200V DC.

Idivayisi yokuxhumanisa ukushisa yesixhumi ngasinye

Ugesi ojwayelekile wokukhipha (8/20us) Ku: 20kA

Isibonakaliso sesimo semishini semodyuli ngayinye yedivayisi yokuvikela ukukhuphuka

Ama-varistors anamandla aphezulu.

Ngokuxhumana okuqondile okuntantayo noma ngaphandle kwakho

Isicelo:

Idivayisi yokuvikela i-LKX Surge, ivikela kuma-voltage okukhanya kwelanga ohlelweni lwelanga (uhlelo lokunikezwa kwamandla e-photovoltaic).

Isetshenziselwa ukuvikela ukukhuphuka kwezingxenye zikagesi kunoma iyiphi enye isekethe ye-DC.

Lawa mayunithi kumele afakwe ngasikhathi sinye kumanethiwekhi e-DC ukuze avikelwe futhi ahlinzeke ngokuvikelwa kwezindlela ezivamile nezihlukene.

Ilungele ukuvikelwa kokukhuphuka kwemishini yomugqa wokunikezwa kwamandla kagesi ye-DC yohlelo lokukhiqiza amandla elanga.

Ukufakwa kanye nokugcinwa:

Kufakwe ngokufana endaweni exhumanayo ye-LPZ1 zone kanye nezindawo ezilandelayo: isilawuli samandla, i-power converter, njll.

Uma i-surge arrester ifakwa ngaphansi kwezimo ezidingekayo, ayidingi ukulungiswa kwesikhathi eside, kodwa idinga ukulungiswa okuvamile kuphela. Uma umbala wefasitela le-alamu ebonakalayo ushintsha ube bomvu (iphutha) ngesikhathi sokusetshenziswa, kubonisa ukuthi i-surge protector yonakele futhi idinga ukulungiswa noma ukushintshwa.
