SPD backup protector T1 series
Incamake y'ibicuruzwa
Dukurikije amahame ya GB18802.1, GB50057 na Q/THQBOO1-2013, impera y'imbere ya SPD loop igomba guhuzwa mu buryo bukurikiranye n'ibikoresho birinda umuriro ukabije bisabwa n'uruganda rukora surge protector.
Kubera ko fuse n'icyuma gito bigabanya umuvuduko w'amashanyarazi bidashobora guhuza na SPD, iyo umuriro udasanzwe cyangwa SPD ikangirika ikananirwa, umuriro n'ibikoresho byangirika kubera inkuba, ibyo bikaba byaragize ingaruka zikomeye ku mikorere isanzwe y'umusaruro!
Muri iki gihe, umubare munini wa miniature circuit breakers zikoreshwa hamwe na SPD ntushobora guhuzwa n'ingingo enye zikurikira:
1. Ihungabana ry'umuraba w'inkuba ryoroshye cyane kwangiza - uburyo bwo kurinda imirabyo burananirwa;
2. Umuvuduko mwinshi w'amashanyarazi atuma imirabyo ihinduka - uburyo bwo kurinda imirabyo ku bikoresho biragabanuka;
3. Ingufu zitagira umuvuduko zituma zihindagurika ntizitemba-amashanyarazi ntabwo asanzwe kandi SPD iri kugurumana;
4. Inkuba igwa nabi - uburyo bwo kurinda imirabyo burananirwa.
Bitewe n’uko ubu nta gikoresho cyihariye cya SPD gishyigikira uburinzi bw’umuvuduko ukabije kiriho mu nganda zirinda inkuba, nyuma y’imyaka itatu y’ubushakashatsi n’iterambere ndetse n’imyaka irenga umwe y’igerageza ritandukanye ryo gupima ibidukikije muri laboratwari, byagaragaye ko SPD backup protector (SCB)
1. Ingufu za SPD zikoreshwa mu gusimbuka zidafite uburebure zifite agaciro ka 4A
2.Umuvuduko w'amashanyarazi udakoresha uruziga urenze 40kA (8/20);
3. Guhagarika umutima kw'imirasire y'imirasire. Gukemura burundu ikibazo kiriho ubu kuko SPD idafite ibikoresho byihariye byo kurinda umuriro ukabije; Ingaruka z'ubufatanye hagati ya SCB na SPD ni ukugenzura ko SPD idafata umuriro kandi ko imirasire y'imirasire idahungabana.
Imikorere n'urwego rw'ikoreshwa
Imashini igabanya umuriro ya SPD yihariye ihujwe mu buryo bukurikiranye kuri SPD loop, kandi igikoresho cyo gutondekanya umuyoboro w'amashanyarazi imbere gikoreshwa kugira ngo umuyoboro muto w'amashanyarazi ucike vuba; Inkuba nyinshi z'amashanyarazi ntizigwa. Kugera ku musaruro w'amashanyarazi urinda umuriro muto w'amashanyarazi wa SPD n'inkuba za SPD zirinda umurabyo mu buryo buhoraho; Ibicuruzwa bya SCB bikoreshwa gusa mu kurinda umuyoboro mwinshi w'amashanyarazi wa SPD, cyangwa mu kurinda umuyoboro w'amashanyarazi. Nyamuneka ntubikoreshe mu bindi bihe.
Ikiranga igicuruzwas
1. Uburyo bwo gucika bugenzurwa na parametero, bushobora gutuma habaho gucana kw'amazi mu buryo butoranijwe;
2. Umuvuduko usigaye w'umuvuduko w'amashanyarazi uri hasi, ushobora kugereranywa n'uwa fuse;
3. Gukoranaho n'ingufu nyinshi, kandi bimara igihe kirekire;
4. Imiterere ya micro-canised, ingano nto, byoroshye kugira ngo amashanyarazi abure mu gutahura SPD;
5. Ibisobanuro byuzuye, byujuje ibisabwa kugira ngo SPD ishyigikire ku rwego rwa T1, T2 na T3.
Gushyiraho umugozi wa 6.35mm bihuye n'ibikenewe mu gushyiraho hirya no hino ku isi.
