Ezinhlelweni zamandla zamanje, amamitha kagesi wesigaba esisodwa-ayisisetshenziswa esibalulekile sokukala ukusetshenziswa kukagesi komsebenzisi. Ukukhetha kwabo kuthinta ngokuqondile ukunemba kokulinganisa, ukuzinza kwesistimu, nezindleko zikagesi zomsebenzisi. Ukukhethwa okufanele kwamamitha kagesi wesigaba esisodwa-ahlobene kuphela nokusebenza kahle kwezinkampani zikagesi, kodwa futhi nokuvikelwa kwamalungelo kanye nezintshisakalo zabasebenzisi bokugcina. Lesi sihloko sizochaza ngokuhlelekile amaphuzu abalulekile okukhethwa kwemitha kagesi yesigaba esisodwa-kusuka ezicini zamapharamitha wobuchwepheshe, izimo zohlelo lokusebenza, izindinganiso zokunikeza izitifiketi namathrendi okuthuthuka kwesikhathi esizayo.
Cacisa izimfuneko zepharamitha yezobuchwepheshe
Ukukhethwa kwamamitha kagesi wesigaba esisodwa- kufanele kuqala kusekelwe ezimfuneko zobuchwepheshe zezicelo zangempela. Amapharamitha angukhiye afaka:
I-1.I-voltage elinganiselwe kanye namanje
I-voltage elinganiselwe yemitha kagesi yesigaba esisodwa ngokuvamile ingu-220V (noma i-110V, kuye ngezinga legridi yamandla esifunda), futhi isilinganiso samanje sidinga ukunqunywa ngokuya ngosayizi womthwalo. Ukucaciswa okujwayelekile kufaka phakathi u-5(60)A, 10(40)A, njll., lapho inani elikubakaki limelela inani eliphezulu lamanje. Isibonelo, imitha kagesi engu-5(60)A ifanele imithwalo yasendlini evamile, kuyilapho ukucaciswa kwamanje okuphezulu (okufana no-10(100)A) kufanelekile ezimbonini noma{14}}izindawo zikagesi ezinamandla aphezulu.
2.Izinga Lokunemba
Ukunemba kwemitha kagesi kuthinta ngokuqondile ukulunga kwenkokhelo. Ngokwamazinga kazwelonke aseShayina, izinga lokunemba lamamitha kagesi wesigaba esisodwa-okusetshenziswa endaweni yokuhlala ngokuvamile Ikilasi 2 (±2% iphutha). Izicelo ezinembayo-eziphakeme (njengamalabhorethri noma izindawo zentengiso) zingase zidinge Ikilasi 0.5S noma amamitha we-Class 1. Lapho ukhetha imitha, khetha imodeli ehlangabezana nezidingo zokunemba ngokusekelwe ezidingweni zakho zokubala.
3.Imvamisa kanye Nenani Lezigaba
Amamitha kagesi wesigaba esisodwa-afanele amagridi kagesi angu-50Hz noma angu-60Hz (ngokuya ngamazinga egridi kazwelonke) futhi asetshenziswa kuphela ukukala amandla-esigaba esisodwa se-AC. Uma-amandla ezigaba ezintathu ehilelekile,-imitha yezigaba ezintathu kufanele kukhethwe.
Ukukhetha Ngokusekelwe Kusimo Sohlelo
Izindawo ezihlukene zokusebenzisa zidinga imisebenzi ehlukene nokuqina kwamamitha kagesi, ngakho ukukhetha okuhlosiwe kuyadingeka:
1.Ugesi Wendawo yokuhlala
Abasebenzisi basekhaya ngokuvamile bakhetha amamitha kagesi wesigaba esisodwa-esigaba esisebenza ngokuyisisekelo. Amamitha ahlakaniphile esimanje aphinde asekele ukufundwa kwamamitha okude kanye nokukhokha kusengaphambili, ukuthuthukisa ukusebenza kahle kokuphatha. 2. Imithwalo yezibani zezentengiso nezezimboni
Izitolo, amahhovisi amancane, nezinye izimo zingase zifake phakathi imithwalo ephezulu (njengama-air conditioner namakheshi). Kunconywa ukusebenzisa-imitha kagesi ebangeni elibanzi (njenge-5(60)A noma 10(40)A) futhi uqinisekise ukuthi inamandla okumelana nokuphazamiseka kwe-harmonic.
3. Izindawo ezikhethekile
Ezindaweni zokushisa eziphezulu, eziswakeme noma eziqinile zikazibuthe kagesi (njengamagumbi angaphansi nezindawo zokusebenzela zasefekthri), kuyadingeka ukuthi ukhethe imitha kagesi enezinga eliphezulu lokuvikela (njenge-IP54 noma ngaphezulu) nokuhambisana okuqinile kwe-electromagnetic (EMC) ukuze kuqinisekiswe-ukusebenza okuzinzile.
Gxila emisebenzini yezobuhlakani nezokuxhumana
Ngokuthuthukiswa kwamagridi ahlakaniphile, imisebenzi eyengeziwe-yamamitha kagesi wesigaba esisodwa iya ibaluleka kakhulu:
1. Amakhono okuxhumana akude
Amamitha kagesi asekela izimiso zokuxhumana ezifana ne-RS-485, LoRa, ne-NB-I-IoT ingakwazi ukubona ukudluliswa kwedatha okukude, ihlele{3}}ukuqapha kwesikhathi sangempela kwezinkampani zikagesi kanye nemibuzo yokuzisiza ngabasebenzisi.
2. Ukukhokha kusengaphambili nokulawula umthwalo
Amamitha kagesi okhokhelwa kusengaphambili asekela ukuthenga ugesi kuqala bese uyawusebenzisa, okunciphisa ingozi yokungakhokhelwa; amanye amamodeli aphezulu-aphinde abe nemisebenzi yokuvikela ukugcwala ngokweqile okunganqamula ukude ukusetshenziswa kwamandla okungavamile{1}}
Ukugcinwa Kwedatha Nokuloga Komcimbi
-Amamitha kagesi wekhwalithi ephezulu kufanele ahlinzeke ngedatha enemininingwane yokusetshenziswa kukagesi (njengokusetshenziswa kwamandla aqandisiwe nsuku zonke/nyanga zonke) kanye nesitoreji sesehlakalo esinephutha ukuze kube lula ukuxazulula izinkinga nokuhlaziywa kokusebenza kahle kwamandla.
Isitifiketi Nokuhambisana
Lapho ukhetha imitha, qinisekisa ukuthi isiphasile isitifiketi esiyimpoqo sikazwelonke (njenge-China Compulsory Certification (CCC)) futhi ithobelana namazinga afanelekile (njengochungechunge lwe-GB/T 17215). Ngaphezu kwalokho, uma imitha ihloselwe ukuthunyelwa ngaphandle noma izimboni ezithile (njengezokuthutha zezokwelapha noma zesitimela), kufanele ihlangabezane nezimfuneko zesitifiketi ezengeziwe (ezifana ne-CE ne-UL).
Amathrendi Azayo Nezincomo Zokukhetha
1.Ukunemba Okuphezulu kanye Nokusebenzisa Amandla Aphansi
Isizukulwane esisha samamitha kagesi sithuthukela ekunembeni okuphezulu kweleveli engu-0.2S-kanye -nokusetshenziswa kwamandla okulindile okuphansi, okuwenza afaneleke izimo ezinezidingo eziqinile zamamitha.
2.Multi-Isilinganiso kanye Nokuphathwa Kokusebenza Kwamandla
Amamitha kagesi asekela isikhathi-sokuthi{1}}sokusebenzisa inkokhiso (ukuphakama nokuvala{2}}intengo ephezulu) angasiza abasebenzisi bakhulise izindleko zikagesi futhi angase abe isici esivamile emakethe yezindawo zokuhlala esikhathini esizayo.
3. I-Modular Design
Amamitha wamandla anamamojula okuxhumana anwebekayo noma izixhumanisi zenzwa angakwazi ukuzivumelanisa nezimo nokuthuthukiswa kobuchwepheshe kwesikhathi esizayo.
Isifinyezo: Ukukhethwa kwemitha-yesigaba esisodwa samandla kudinga ukucatshangelwa okuphelele kokucaciswa kobuchwepheshe, izimo zohlelo lokusebenza, izidingo ezihlakaniphile, nokuthobela imithetho. Abasebenzisi bayelulekwa ukuthi bacacise izidingo zabo ngaphambi kokuthenga nokubeka kuqala amabhrendi athenjwayo. Xhumana nonjiniyela kagesi ochwepheshe uma kudingeka ukuze uqinisekise umsindo kanye nokukhetha{3}}okusebenzayo.
