I. Gushira mu migwi hakurikijwe uko bikoreshwa
1. Agasanduku ko gutanga urumuri
Ahanini izo sandugu zikoreshwa mu kugenzura urumuri mu ngo no mu biro, akenshi zikorana n’amashanyarazi make (10A-63A) kandi zifise ibice vy’imbere canke ibikoresho vyo gukingira amashanyarazi. Birakomeye, biroroshe gushiramwo, kandi birabereye gucunga umuzunguruko utangajwe.
2. Agasanduku ko gutanga amashanyarazi
Izo sandugu zakozwe cane cane ku bikoresho vy’umuyagankuba bifise ubushobozi bwinshi-nk’ibikoresho vy’inganda n’ibikoresho vy’umuyagankuba, zishobora gukorana n’amashanyarazi y’umuyagankuba mwinshi (100A{3}}630A) kandi zitanga uburinzi bw’umuyagankuba urenze urugero n’umuyagankuba muto. Izo sandugu zisanzwe ziboneka mu mahinguriro no mu mahugurwa kandi zisaba ama circuit breaker afise ubushobozi bwinshi.
3. Agasanduku ko gutanga ibipimo
Izo nsaka zifise ibikorwa vyo gupima amashanyarazi kandi zikoreshwa mu gupima no gukwiragiza inguvu. Akenshi zikoreshwa ku bwinjiriro bw’imibano canke inyubakwa z’ubudandaji. Dushingiye ku ngingo mfatirwako z’igihugu (nk’iza GB/T 7251.3), ukuri kwavyo gutegerezwa kuba guhuye n’ingingo mfatirwako zo mu rwego rwa mbere canke rwa kabiri.
II. Gushira mu migwi hakurikijwe uburyo bwo gushiramwo
1. Ubutaka-Isanduku yo Gukwiragiza
Iyo sandugu ifashe ku ruhome canke ku gifatanya, yoroshe gushiramwo ariko ntiyishimisha cane. Ni vyiza mu gusanura inyubakwa za kera canke mu gukoresha amashanyarazi y’igihe gito.
2. Agasanduku k'ugukwiragiza kahishijwe
Ishizwe mu ruhome, n'igipande gusa kigaragara, itanga uburyo bwo gusa n'ubwiza, ariko bisaba ko isandugu ibanza-hambwa. Ikunda gusangwa mu nyubakwa nshasha zo kubamwo canke mu migambi yo gusanura.
3. Hasi-Isanduku yo Gukwiragiza
Ico kigega ni kinini cane kandi gishirwa hasi ataco kivuze. Ni vyiza ku bibanza bifise ibisabwa bikomeye vyo gutanga amashanyarazi, nk’ibibanza vy’amashanyarazi n’ibibanza vy’amakuru.
III. Gushirwa mu migwi hakurikijwe ibikoresho
1. Agasanduku ko gutanga ivyuma
Ikozwe mu cuma gikonje-canke icuma kitagira ibara, ifise IP rating nini (IP54 canke irenga) kandi ishobora guhangana n’ibintu bikomeye, ariko isaba gushirwa hasi neza no kwirinda umugese.
2. Agasanduku ko gutanga amapulasitike
Itanga uburinzi bwiza cane, iraremereye, kandi ntishobora gusenyuka-, ariko irafise ubushobozi buke bwo gukingira umuriro (itegerezwa guhura n’ubushobozi bwo gukingira umuriro bwa V0). Ikoreshwa cane cane mu ngo canke mu bibanza vyumye.
IV. Gushirwa mu migwi hakurikijwe urugero rw'uburinzi
1. Ivyategekanijwe (IP20-IP30)
Ikingiwe gusa inkungugu n’umuco, ibereye ahantu h’imbere mu nzu humye.
2. Idashobora guterwa n'amazi (IP65-IP67)
Ikingiwe n’amazi y’umuvuduko munini-n’ugubika mu mazi mu gihe gito, ibereye ahantu hatose nk’aho hanze n’aho munsi y’ubutaka.
