I-Advanced Dc Surge Protective Device Ivikela Ukufakwa Okubalulekile Kwelanga

Iklanyelwe izindawo ze-DC ezifunayo, idivayisi ihlanganisa izakhiwo zokuvikela ezisiteji eziningi. Ingxenye yayo ye-T1 iphatha umjovo wamanje wombani oqondile (Iimp 12.5kA 10/350μs), kuyilapho i-elementi ye-T2 ilawula ama-surges (Ku-20kA-40kA 8/20μs). Leli su lokuvikela elididiyelwe libamba ngempumelelo ukugcwala ngokweqile kwesikhashana ngaphansi kwemikhawulo yezinto ezivikelwe. Ama-MOV cores afaka ubuchwepheshe bokukhipha isixhumi esishisayo obuthuthukisiwe obuhluleka ngokuzenzakalelayo ukuphepha phakathi nezimo zokuphela kwempilo, okuvimbela ubungozi bokubaleka kokushisa kumasekhethi e-DC aqhubekayo.

Ukuguquguquka kokucushwa kuchaza lokhu Idivayisi ye-Dc Surge Protective, etholakala kuzo zombili izinguqulo ze-2P ne-3P. Isekela izilinganiso zamandla kagesi e-DC amathathu abalulekile angu-500VDC, 1000VDC, kanye ne-1500VDC okwenza ihambisane nokucushwa okuhlukahlukene kwe-solar kusuka ekufakweni kwendawo yokuhlala kuya kwezisetshenziswayo. Idizayini ekhwezekayo, ye-DIN-rail yenza kube lula ukuhlanganisa phakathi kwezindawo ezivalekile kuyilapho kugcinwa ama-creepage afanele kanye namabanga okukhipha adingekayo ezinhlelweni ze-DC ezinamandla kakhulu.

Izici zokuphepha eziphelele ziqinisekisa ukusebenza okuthembekile. Izinkomba zesimo sokubukwa ezihlanganisiwe zinikeza isiqinisekiso esisheshayo sokulungela ukusebenza, kuyilapho othintana nabo besignali bekude bavumela ukuhlanganiswa kokuqapha kwesistimu. I I-SPD igcina i-UL 1449 4th Edition kanye nezitifiketi ze-IEC 61643-31, iqinisekisa ukusebenza kwayo ngaphansi kwamazinga omhlaba aqinile. Izindlu eziqinile ze-thermoplastic zinikeza inkomba ephezulu yokuqhathanisa yokulandelela (CTI>600) ukuze kuthuthukiswe ukumelana nokungcola ezindaweni ezinokhahlo.

Uchungechunge lwe-BY08DC lusungula amabhentshimakhi amasha okuvikela ingqalasizinda yelanga. Lokhu ukusebenza okuphezulu Idivayisi ye-Dc Surge Protectiveiletha ukuzivikela okubalulekile okudidiyelwe kwe-T1+T2 ngokumelene ne-thre yesikhashanaI-ATS ngobuchwepheshe bayo obuphezulu be-MOV kanye nezinketho zokucushwa eziguquguqukayo. Abathuthukisi be-Solar kanye nama-opharetha bathola isixazululo esibalulekile sokuvikela esikhulisa isikhathi sokusebenza kwesistimu ngenkathi sivikela ukutshalwa kwezimali okubalulekile kwemishini eseceleni kwe-DC ekulimeni kokushisa kukagesi.
