Izivalo zombane ziza kuluhlu olubanzi lobukhulu, iimilo, imathiriyeli, kunye noyilo.Nangona zonke zineenjongo ezifanayo engqondweni - ukukhusela izixhobo zombane ezivaliweyo kwindawo, ukukhusela abasebenzisi ekutshitshisweni kombane, kunye nokunyusa izixhobo zombane - zinokwahluka kakhulu.Ngenxa yoko, iimfuno zokuvala umbane ziphenjelelwa kakhulu kwiimfuno zabasebenzisi.
Xa sithetha ngeemfuno zeshishini kwi-enclosure zombane, ngokuqhelekileyo sithetha ngemigangatho kunemimiselo enyanzelekileyo (oko kukuthi, iimfuno).Le migangatho iququzelela unxibelelwano phakathi kwabavelisi kunye nabathengi.Bakwathethelela ukhuseleko, uyilo olusebenzayo, kunye nokusebenza okuphezulu.Namhlanje, siza kujonga eyona migangatho ixhaphakileyo yokuvaleka, kunye nezinye zezona zinto zibaxhalabisayo abantu xa beodola ikhabhathi yombane okanye indawo ebiyelweyo.
Imigangatho eqhelekileyo yeeNdawo ezivaliweyo
Uninzi lwabavelisi beendawo ezivaliweyo zombane bathobela iimfuno zokhuseleko ezibekwe ngumbutho woluhlu oluthembekileyo.EUnited States, i-Underwriters Laboratories (UL), i-National Electrical Manufacturers Association (NEMA), kunye ne-Intertek yimibutho emithathu eluhlu oluphambili.Abavelisi abaninzi basebenzisa i-International Electrotechnical Commission kumlinganiselo wehlabathi (IEC), ebeka usapho lwemigangatho yokuvaleka kombane, kunye neZiko leeNjineli zoMbane kunye ne-Electronics (IEEE), umbutho wobuchwephesha obuseta imigangatho yokuqhubela phambili itekhnoloji kunye nokuzuza uluntu. .
Eyona migangatho mithathu ixhaphakileyo yombane ipapashwa yi-IEC, NEMA, kunye ne-UL, njengoko bekuphawuliwe ngaphambili.Kufuneka ujonge ngokukhethekileyo upapasho lwe-NEMA 250, IEC 60529, kunye ne-UL 50 kunye ne-50E.
IEC 60529
Amanqanaba okhuseleko lokungena achongwa kusetyenziswa ezi khowudi (ezaziwa ngokuba zii-Characteristic Numerals) (ekwaziwa ngokuba zii-IP ratings).Bachaza indlela olu khuselo olukhusela ngayo izinto ezikuyo ekufuma, eluthulini, eluthulini, ebantwini nakwezinye izinto.Nangona umgangatho uvumela ukuzivavanya, abavelisi abaninzi bakhetha ukuba iimveliso zabo zivavanywe ngokuzimeleyo ukuba ziyahambelana.
NEMA 250
I-NEMA ibonelela ngokhuseleko lokungena ngendlela efanayo ne-IEC eyenza ngayo.Nangona kunjalo, ibandakanya ukwakhiwa (ubuncinci bemigangatho yoyilo), ukusebenza, uvavanyo, ukubola, kunye nezinye izihloko.I-NEMA ihlela iindawo ezivaliweyo ngokusekelwe kuHlobo lwazo kunokalo lwe-IP yazo.Ikwavumela ukuzithobela, nto leyo ephelisa imfuneko yokuhlolwa kwemizi-mveliso.
UL 50 kunye ne-50E
Imigangatho ye-UL isekelwe kwiinkcukacha ze-NEMA, kodwa ikwafuna ukuvavanywa komntu wesithathu kunye nokuhlolwa kwendawo ukuqinisekisa ukuthotyelwa.Imigangatho yeNEMA yenkampani inokungqinwa ngesatifikethi se-UL.
Ukukhuselwa kokungena kubhekiswa kuyo yomithathu imigangatho.Bavavanya ukukwazi kwendawo ebiyelweyo ukugada ekungeneni kwezinto eziqinileyo (ezifana nothuli) kunye nolwelo (njengamanzi).Bakwathathela ingqalelo ukhuseleko lomntu kumacandelo ayingozi alendawo ebiyelweyo.
Amandla, ukutywinwa, izinto eziphathekayo / ukugqiba, i-latching, ukutsha, ukungena komoya, ukunyuka, kunye nokukhuselwa kwe-thermal zonke zigutyungelwe yi-UL kunye ne-NEMA yemigangatho yokuyila i-enclosure.I-Bonding kunye ne-grounding nazo zibhekiswe yi-UL.
Ukubaluleka kweMigangatho
Abavelisi kunye nabathengi banokunxibelelana ngokulula malunga nomgangatho wemveliso, iimpawu, kunye nenqanaba lokomelela ngenxa yemigangatho.Bakhuthaza ukhuseleko kwaye bakhuthaze abavelisi ukuba benze iimpahla ezisebenzayo kunye nezizalisekisa imigangatho ethile yokusebenza.Okona kubaluleke kakhulu, bancedisa abasebenzisi ekwenzeni ukhetho olunolwazi ukuze bakhethe iindawo ezivaliweyo ezihambelana neemfuno zabo zesicelo.
Kuya kubakho umahluko omkhulu kuyilo lwemveliso kunye nokusebenza ukuba bekungekho migangatho engqongqo.Endaweni yokugxila ekufumaneni elona xabiso liphantsi, sikhuthaza bonke abathengi ukuba baqwalasele imigangatho yoshishino xa befumana iindawo ezivaliweyo.Umgangatho kunye nokusebenza kubaluleke kakhulu kuneendleko zexesha elide.
Iimfuno zoMthengi
Ngenxa yokuba abavelisi beendawo ezivaliweyo zombane bafuneka kuphela ukuba bafezekise iimfuno ezimbalwa (imigangatho yabo), uninzi lweemfuno zokuvala umbane zivela kubathengi.Zeziphi iimpawu ezifunwa ngabathengi kwindawo ebiyelweyo yombane?Ziziphi iingcinga namaxhala abo?Xa ufuna ikhabhathi entsha yokubamba izinto zombane, zeziphi iimpawu kunye neempawu omele uzijonge?
Qwalasela le ngqwalasela ilandelayo xa usenza uluhlu lwakho lweemfuno kunye nezinto ozikhethayo ukuba ufuna indawo ebiyelweyo yombane:
Imathiriyeli ebiyelweyo
Izivalo zenziwe ngezinto ezininzi, kubandakanya isinyithi, iplastiki, i-fiberglass, i-die-cast, kunye nezinye.Qwalasela ubunzima, uzinzo, iindleko, iinketho zokunyusela, inkangeleko, kunye nokuqina kokhetho lwakho njengoko uphanda ngazo.
Ukhuseleko
Phambi kokwenza ukuthenga kwakho, jonga ngaphezulu kweereyithingi zeNEMA, ezibonisa umgangatho wemveliso wokhuseleko lokusingqongileyo.Kuba ezi zilinganiso ngamanye amaxesha aziqondwa kakuhle, thetha nomenzi/umthengisi ngeemfuno zakho kwangethuba.Iireyithingi ze-NEMA zinokukunceda ufumanise ukuba indawo ebiyelweyo ikulungele na ukusetyenziswa ngaphakathi nangaphandle.ingaba inokukhusela ekungeneni kwamanzi, ingaba inokumelana nokubunjwa kweqhwa, kunye nokunye okuninzi.
Ukunyuka kunye nokuqhelaniswa
Ukunyuka kunye nokuMamela: Ngaba indawo yakho ebiyelweyo iya kuxhonywa eludongeni okanye ime ngokukhululekileyo?Ingaba indawo ebiyelweyo iza kujongwa ngokuthe nkqo okanye ngokuthe tye?Qinisekisa ukuba indawo ebiyelweyo oyikhethayo iyahlangabezana nezi mfuno zolungiselelo zisisiseko.
Ubungakanani
Ukukhetha ubungakanani obuchanekileyo bendawo ebiyelweyo kunokuvela ngokuthe ngqo, kodwa kukho izinto ezininzi ezinokwenzeka.Ukuba awulumkanga, unako "ukuthenga kakhulu," uthenge indawo ebiyelweyo ngakumbi kunokuba ufuna ngokwenene.Nangona kunjalo, ukuba indawo ebiyelweyo ingqina ukuba incinci kakhulu kwixesha elizayo, kunokufuneka uphucule.Oku kuyinyani ngakumbi ukuba indawo yakho ebiyelweyo iya kufuna ukulungiselela inkqubela phambili yetekhnoloji yexesha elizayo.
Ulawulo lweMozulu
Ubushushu bangaphakathi nangaphandle bunokwenzakalisa izixhobo zombane, ngoko ke ulawulo lwemozulu lubalulekile.Kusenokufuneka uphande iindlela zokudlulisa ubushushu ngokusekelwe kwimveliso yobushushu besixhobo sakho kunye nokusingqongileyo kwangaphandle.Kubalulekile ukukhetha isixokelelwano sokupholisa esichanekileyo kwindawo yakho ebiyelweyo.
