Umutwe: Sobanukirwa ibyiza nibisabwa byaNH urukurikirane

kumenyekanisha

Mu rwego rwubwubatsi bwamashanyarazi, guhitamo ibice bikwiye kubisabwa byihariye ni ngombwa kugirango umutekano wizewe kandi wizewe wa sisitemu y'amashanyarazi.Mugihe cyo gukingira fuse kurinda, urukurikirane rwa NH rugaragara nkimwe mumahitamo menshi kandi yizewe kumasoko.Muri iyi blog, tuzacukumbura muburyo burambuyeNH urukurikirane, muganire ku nyungu zabo nibisabwa, kandi umenye impamvu basabwa cyane naba injeniyeri kwisi.

Igika cya 1: NikiNH urukurikirane?

NH urukurikiraneni imikorere yo hejuru, voltage ntoya yagenewe gutanga umutekano wizewe kurinda imiyoboro ikabije kandi ngufi.“NH” bisobanura “Niederspannungs-Hochleistungssicherung”, iryo rikaba ari ijambo ry'ikidage risobanurwa ngo “voltage ntoya ikora neza”.Iyi fuse isanzwe ikoreshwa muri sisitemu yo gukwirakwiza amashanyarazi ibyiciro bitatu, cyane cyane mubisabwa aho kurinda moteri ari ngombwa.

Igika cya kabiri: ibyiza byaNH urukurikirane

NH urukurikiranetanga ibyiza byinshi kurenza fus.Ubwa mbere, izo fuse zifite ubushobozi buhebuje bwo kumena, bivuze ko zishobora guhagarika byimazeyo kwangirika kwinshi.Iyi mikorere iremeza ko fuse ifungura byihuse uruziga, ikarinda kwangirika kwibikoresho nibishobora guteza amashanyarazi.Mubyongeyeho, NH urukurikirane rwa fuse ruzwiho kuba rwinshi rwumuzunguruko mugufi no kurwanya ubushyuhe, bifasha kwagura ubuzima bwabo no kongera igihe.

Byongeye kandi, ingano yuzuye yaNH urukurikiraneikiza umwanya w'agaciro mumabati y'amashanyarazi.Ibi nibyingenzi byingenzi kubisabwa aho umwanya ari muto.Byongeye kandi, guhuza neza kwi fus bituma gukora neza kandi bikagabanya ibyago byo gutembera kubwimpanuka, bityo bikongera imikorere rusange numutekano wa sisitemu yamashanyarazi.

Ingingo ya gatatu: ikoreshwa ryaNH urukurikirane

NH urukurikiranezikoreshwa cyane mubikorwa bitandukanye no mubikorwa bitewe nibikorwa byiza biranga.Bakunze gukoreshwa mubigo bishinzwe kugenzura ibinyabiziga (MCCs) kugirango barinde moteri hamwe nuyobora.Izi fuse zifite uruhare runini mukurinda moteri ibihe birenze urugero biterwa namakosa cyangwa ibikoresho byananiranye.

Urutonde rwa NH rukoreshwa kandi muri sisitemu yo guhagarika amashanyarazi adahagarara (UPS) kugirango itange uburinzi bwizewe kumitwaro ikomeye nkibigo byamakuru, ibitaro nibindi bikorwa byoroshye.Ikosa ryinshi rigezweho hamwe nigihe cyo gusubiza byihuse bya fuse bituma biba byiza kugirango barebe imbaraga zidacogora no kugabanya igihe cyateganijwe.

Ibindi bikorwa bizwi cyane kuri NH ikurikirana ya fuse harimo guhinduranya, kurinda transformateur, imashini zinganda no kwishyiriraho.Guhinduranya hamwe nubushobozi bwo gukemura ibibazo byinshi byamazi ya NH ya fuse bikwiranye na sisitemu zitandukanye zamashanyarazi.

Igika cya 4: Guhitamo IkosoraNH Urutonde

MugiheNH urukurikiranetanga imikorere myiza, guhitamo igipimo cyiza cya fuse kumurongo runaka ni ngombwa.Ba injeniyeri bagomba gusuzuma ibintu nkibiteganijwe kugezubu, voltage yagenwe, hamwe nibidukikije mugihe bahisemo fuse ikwiye.Kugisha inama injeniyeri w'amashanyarazi ufite uburambe cyangwa kwerekeza kubisobanuro byakozwe nuwayikoze birashobora kugufasha kumenya igipimo cya fuse gikenewe kugirango imikorere ikorwe neza.

Muri make

NH urukurikiranetanga igisubizo cyiza kuburinzi bukora neza kandi bwizewe kurinda imiyoboro ikabije kandi ngufi.Nubushobozi bwabo bwo kumeneka cyane, ubunini buringaniye hamwe nigihe kirekire, babaye ihitamo ryambere ryaba injeniyeri benshi b'amashanyarazi kwisi.Yaba ikigo gishinzwe kugenzura ibinyabiziga, sisitemu ya UPS, cyangwa ibikorwa bitandukanye byinganda, feri ya NH ikomeza kwerekana agaciro kayo mukurinda amashanyarazi.Mugusobanukirwa inyungu nibisabwa byaNH urukurikirane, injeniyeri barashobora gufata ibyemezo byuzuye kandi bakemeza ko amashanyarazi akora neza.
