GUSHYA GUSHYA: Siemens SITOR 3NE3340-8 Semiconductor Fuse Noneho mububiko
Icyitegererezo
Tunejejwe no kumenyesha ko iboneka rya Siemens SITOR 3NE3340-8 semiconductor fuse ihuza, ikintu gikomeye cyo kurinda ibikoresho bya elegitoroniki. Iyi NH2 yubunini bwa fuse iranga icyuma cyerekanwe hamwe nicyerekezo cyimbere kandi gitanga 900A igipimo cyubu kuri 690V AC, cyagenewe cyane cyane kurinda amashanyarazi yumuriro mugihe gito cyumuzunguruko. Ibikoresho bya fuse byihuta cyane biranga (icyiciro cyibikorwa bya aR) bituma ihagarikwa ryizewe muri milisegonda, bikarinda gutsindwa gukabije kwa IGBTs zihenze, MOSFETs, na diode muguhindura inshuro, sisitemu ya UPS, hamwe na moteri yoroshye ya moteri. Hamwe nuburebure bwa 110mm, 3NE3340-8 ishyiraho nta nkomyi muri base ya LV HRC fuse, guhinduranya imiyoboro, cyangwa irashobora guhita ihindurwamo bisi ikoresheje imashini ya M10 kugirango ikore neza. Igishushanyo mbonera gipima uburebure bwa 149mm x 59mm z'ubugari x 70mm z'uburebure, butanga umwanya-wo kurinda umwanya mu mbaho zishinzwe kugenzura no gukwirakwiza amashanyarazi.
Ibintu by'ingenzi
3NE3340-8 itanga uburyo budasanzwe bwo kurinda hamwe na 100kA ifite ubushobozi bwo guhinduranya, ikabuza umutekano muke cyane amashanyarazi akomeye muri sisitemu ishingiye kuri semiconductor. Ikigereranyo cy'ubushyuhe gikora -20 ° C kugeza kuri + 50 ° C, hamwe n'ubushobozi bwo kubika kuva kuri -40 ° C kugeza kuri + 80 ° C, bigatuma kwizerwa mubidukikije. Gutakaza ingufu ku bipimo bigezweho 165W kuri pole, byashyizwe mu bikorwa byo gucunga amashyuza mu bigo bituwe cyane. Guhuza icyuma cyerekana ibimenyetso bya feza kuburwanya buke bwo guhangana no kwimurwa kwizewe. Kubahiriza ibyemezo bya IEC 60269-4, UL, na CCC bifasha kohereza isi yose. Imbere-yimashini yerekana imiterere itanga icyerekezo gisobanutse / gifungura uruziga rwerekana nta mfashanyo ifasha. Ingano yubwubatsi ya NH2 yemeza guhuza hamwe na fuse isanzwe hamwe na sisitemu shingiro. Ubushyuhe burenze urugero bushobora kwihanganira ubushobozi (95% ugereranije n'ubushyuhe buri kuri 50 ° C) butuma bikwiranye n’ibibazo by’abaminisitiri bitabujije.
Ibyitegererezo bifitanye isano na SITOR 3NE33
Umuryango wa SITOR 3NE utanga uburinzi bwuzuye kubikoresho bitandukanye bya semiconductor. Uwiteka3NE3338-8itanga amanota 800A kuri 690V AC kubisabwa bike biriho ubu, mugihe3NE3337-8itanga ubushobozi 710A. Uwiteka3NE3336-0Bigera kuri 630A kuri 690V kubahindura imbaraga-ziciriritse. Kubisabwa hejuru ya voltage, the3NE3336-4variant ikora kuri 1000V AC hamwe na 450A. Uwiteka3NE3334-0Bitanga ubushobozi bwa 500A kubisabwa-bisaba ibiciro. Abakiriya bakeneye iboneza ritandukanye barashobora guhitamo3NE3335hamwe na blade ikomeye. Moderi zose zisangiye ibintu bisa na NH2, ibipimo bigenda byiyongera, hamwe nuburinzi bwihuse bwokwirinda, bigafasha guhitamo abafite fuse bahisemo murwego rwo hejuru rwokwirinda mugihe bahindura igipimo cyubu kubushobozi bwihariye bwa IGBT.
Ibyiza byo Kurushanwa
Nkumucuruzi wihariye wo gucuruza inganda, dutanga urwego rutagereranywa rwo gutanga amasoko no guhuza amasoko. Iwacu ibisubizo byinshi byo kwishyura yakira gahunda yo kohereza insinga hamwe ninguzanyo yatanzwe kubakiriya babishoboye, koroshya kugura akazi. Turakomeza ibarura ryingenzi mu turere two gukwirakwiza uturere, gushoboza gutanga mu minsi 5-7 y'akazi ku masoko akomeye yinganda kwisi yose. Iwacu umuyoboro mugari Ikwirakwiza imiyoboro ihanitse yo mu Burayi no muri Aziya, ikemeza neza ibice bya Siemens bikurikiranwa nta mbogamizi imwe itanga. Ubu buryo butandukanye bwerekana uburyo bwo kuboneka no mugihe cyo kugabanya ibicuruzwa. Inzobere zacu tekinike zitanga inama kubijyanye no guhitamo uburyo, kuyobora, no kugenzura guhuza. Binyuze mu bikoresho byiza hamwe nubufatanye butaziguye, dukuraho abahuza bitari ngombwa mugihe twihutisha kuzuza ibyateganijwe, bigatuma tuba igisubizo cyatoranijwe cyo guterana byihutirwa guterana no gufata neza imishinga.
Kubisobanuro byihuse cyangwa kugisha inama tekinike, nyamuneka hamagara itsinda ryacu ryagurishijwe.
