Ese SPD zishobora kurinda ubwoko bwose bw'ihungabana ry'amashanyarazi?
SPD zagenewe kurinda ubwiyongere bw'ingufu nyinshi z'igihe gito, ariko zifite imipaka ishingiye ku gipimo cyazo. Zishobora kudakingira byuzuye ubwiyongere bw'ingufu nyinshi cyangwa imirabyo itaziguye mu gihe igikoresho kidahawe amanota akwiye. Kugira ngo habeho uburinzi bwuzuye, hashobora gukoreshwa ubwoko butandukanye bwa SPD.
Itandukaniro riri hagati ya SPD y'igikoresho cyo kurinda ubwoko bwa 1 n'ubwoko bwa 2
Ubwoko bwa 1 SPD yagenewe guhangana n’izamuka ry’amashanyarazi rikabije rikoresha ingufu nyinshi, akenshi riterwa n’inkuba zitaziguye. Ibi bikoresho bikunze gushyirwa ku muryango w’inyubako, bigatanga uburinzi bw’ibanze ku bihe nk’ibi bikomeye. SPD zo mu bwoko bwa 1 zishobora gucunga imiyoboro y’amashanyarazi igera kuri 100 kA cyangwa irenga, zikoresha ibice bikingira ingufu nyinshi nka za gacupa z’umwuka kugira ngo sisitemu irindwe mu gihe cy’izamuka rikomeye.
Ubwoko bwa 2 SPD Itanga uburinzi ku bice by’amashanyarazi bikwirakwizwa, ikemura ibibazo bishobora kuba bikiriho nyuma yo gukingira ubwoko bwa 1. Ishyizwe ku mapine akwirakwiza cyangwa ku mapine aciriritse, SPD zo mu bwoko bwa 2 zigenewe gucunga umuvuduko muke w’amashanyarazi, akenshi kugeza kuri 20-40 kA kuri buri cyiciro. Ibi bikoresho birimo ibice nka Metal Oxide Varistors (MOVs) cyangwa Gas Discharge Tubes (GDTs) kugira ngo bitange uburinzi buhagije ku bikoresho nyuma yo gukingira umuvuduko w’amashanyarazi.
T1+T2 SPD ihuza ibyiza bya SPD zo mu bwoko bwa 1 na 2, itanga uburinzi bwuzuye kuri sisitemu yose y'amashanyarazi. Mu gushyira SPD yo mu bwoko bwa 1 ku muryango munini w'amashanyarazi kugira ngo ikemure ukwiyongera kw'ingufu nyinshi na SPD yo mu bwoko bwa 2 muri sisitemu yo gukwirakwiza kugira ngo irinde uburinzi bw'inyongera, SPD za T1 + T2 zitanga uburinzi bukomeye ku bwinshi bw'izamuka ry'ingufu. Ubu buryo buhuriweho ni bwiza ku bidukikije bishobora guteza akaga nko mu bigo by'amakuru, ibitaro, n'inganda, aho kurinda ukwiyongera kw'ingufu ari ingenzi cyane.
Iyo hakenewe ibikoresho byinshi byo kurinda umuvuduko w’amashanyarazi (SPD) kugira ngo birinde icyuma gishyirwamo, ni ngombwa ko bihuzwa kugira ngo bikore neza hamwe. Niba ibikoresho bya SPD bikomoka ku nganda zitandukanye, ni ngombwa kugenzura ko bihuye. Uwabishyizeho n'ababikora ni bo batanga inama nziza zo kwemeza ko ibikoresho bya SPD bikora neza hamwe.
Igikoresho cyo kurinda Surge (SPDs) ni iki?
Igikoresho cyo Kurinda Ingufu (SPD), kizwi kandi nk'ikirinda ingufu, cyagenewe kurinda ibikoresho by'ikoranabuhanga ingufu z'amashanyarazi n'ingufu z'ingufu z'ingufu z'ingufu. Gikora nk'igice cy'ingenzi muri sisitemu yo kurinda amashanyarazi. SPD ihuzwa hamwe n'urusobe rw'amashanyarazi rw'imizigo irinda, bivuze ko ishobora gukoreshwa ku nzego zitandukanye z'umuyoboro w'amashanyarazi. Iyo ihujwe hamwe, SPD igaragaza impedance nyinshi mu bihe bisanzwe. Ariko, iyo habayeho impedance y'ingufu z'ingufu z'ingufu z'ingufu, impedance ya SPD iragabanuka, bigatuma ingufu z'amashanyarazi zinyura muri icyo gikoresho kandi zikava ku bikoresho by'ingenzi. Iyi nzira ifasha mu gukumira kwangirika kw'ibikoresho by'ikoranabuhanga by'agaciro binyuze mu kwemeza ko ingufu z'ingufu z'ingufu z'ingufu zicungwa neza.
