I. Gutondekanya kubisabwa
1. Itara ryo gukwirakwiza
Ahanini ikoreshwa mugucana urumuri rwamazu mumazu no mubiro, utwo dusanduku mubisanzwe dukora imizigo mike (10A-63A) kandi ifite ibyuma bimena imbere cyangwa ibikoresho byo gukingira. Nibyoroshye, byoroshye gushiraho, kandi bikwiranye no gukwirakwiza imiyoborere.
2. Agasanduku ko gukwirakwiza ingufu
Yateguwe byumwihariko kubikoresho byamashanyarazi - ibikoresho byamashanyarazi nkibikoresho byinganda na moteri yamashanyarazi, utwo dusanduku dukora imizigo myinshi (100A - 630A) kandi itanga uburemere burenze kandi - kurinda umuzunguruko. Utwo dusanduku dusanga mu nganda no mu mahugurwa kandi bisaba imbaraga zumuzunguruko.
3. Kugereranya Agasanduku k'isaranganya
Utwo dusanduku twahujije ibikorwa byo gupima amashanyarazi kandi bikoreshwa mugupima ingufu no gukwirakwiza. Bakunze gukoreshwa kumuryango wabatuye cyangwa inyubako zubucuruzi. Ukurikije ibipimo byigihugu (nka GB / T 7251.3), ubunyangamugayo bwabo bugomba kuba bujuje icyiciro cya 1 cyangwa icyiciro cya 2.
II. Gutondekanya muburyo bwo kwishyiriraho
1. Ubuso - Agasanduku ko gukwirakwiza
Bishyizwe kumurongo cyangwa urukuta, iyi sanduku iroroshye kuyishyiraho ariko ntigushimishije. Birakwiriye kuvugurura inyubako zishaje cyangwa gusaba amashanyarazi by'agateganyo.
2. Agasanduku ko gukwirakwiza
Yashyizwe mu rukuta, hamwe gusa n'ikibaho cyerekanwe, itanga isura nziza cyane, ariko isaba agasanduku kuba mbere - gushyingurwa. Bikunze kuboneka mumazu mashya yo guturamo cyangwa imishinga yo kuvugurura.
3. Igorofa - Agasanduku ko gukwirakwiza
Agasanduku nini kandi gashyizwe hasi. Irakwiriye ahantu hamwe nibisabwa bigoye gukwirakwiza ingufu, nkibisobanuro hamwe namakuru ya data.
III. Gutondekanya kubikoresho
1. Agasanduku ko gukwirakwiza ibyuma
Ikozwe mu bukonje - ibyuma bizunguruka cyangwa ibyuma bidafite ingese, ifite IP yo hejuru (IP54 cyangwa irenga) kandi irwanya ingaruka zikomeye, ariko isaba guhagarara neza no kwirinda ingese.
2. Agasanduku ko gukwirakwiza plastike
Itanga insulente nziza, yoroshye, kandi irashobora kwangirika -, ariko ifite umuriro muke (igomba guhura na V0 flame retardancy). Ikoreshwa cyane mumazu cyangwa ahantu humye.
IV. Gutondekanya kurwego rwo kurinda
1. Bisanzwe (IP20-IP30)
Irinzwe gusa ivumbi no kumurika urumuri, bikwiranye nibidukikije byumye.
2. Amashanyarazi (IP65-IP67)
Kurindwa hejuru y - indege zamazi hamwe no kwibiza mugihe gito, bibereye ahantu hatose nko hanze no munsi.
