Njengamanje, ukusetshenziswa kwetheminali yokushintsha amandla emikhiqizweni ye-elekthronikhi sekuphenduke inkambiso yentuthuko, futhi izingxenye zokushintsha kwesiphetho samandla zikhula kancane kancane, futhi zingathwala amandla amakhulu okukhiphayo.Ngokukhula kwevolumu yetheminali, isidingo sendima yabo emishinini nasezinsizeni siba sobala ngokwengeziwe, futhi badlala indima ebaluleke kakhulu ekuqinisekiseni izici zezimpahla.Okulandelayo empeleni kwethula izici ezibalulekile zokukhethwa kwamatheminali ezintambo ayingozi.
Okokuqala, izakhi zesixazululo samandla okukhiphayo
Enye yezinto zokuqala okufanele zicatshangelwe yikhono lengxenye yokusebenza ngamandla okukhiphayo.Akukho ukucaciswa okufanayo kokuchaza amandla okukhiphayo nezici zetheminali.Ukucaciswa namamodeli wamabhulokhi wetheminali akhiqizwa eYurophu angamazinga e-IEC, kuyilapho lawo akhiqizwa e-United States angamazinga e-UL.
Umehluko phakathi kwalezi zincazelo ezimbili mkhulu kakhulu.Onjiniyela bezobuchwepheshe abangayiqondi indlela yohlobo lomkhiqizo basengozini enkulu yokusebenzisa izingxenye ezingafinyeleli ezingeni elidingekayo lamandla okukhiphayo, noma ukusebenzisa izingxenye ezicaciswe zazo ezedlula kude izimfuneko zokuklama.EYurophu, isilinganiso samanje sengxenye sinqunywa izinga lokushisa lomqhubi wensimbi lapho kutholwa khona i-current.Uma izinga lokushisa lephinikhodi yensimbi lingaphezulu kuka-45℃ kunezinga lokushisa elisebenzayo, izisebenzi zokulinganisa ezinembile zizosebenzisa lamanje njengevelu ye-voltage elinganiselwe (noma yamanje ephakeme) yengxenye.Enye into ekucacisweni kwe-IEC yimanje evumelekile, engama-80% wamanje omkhulu.Ngokuphambene, ukucaciswa kwe-UL kusetha ukuvunyelwa kwamanje kwengxenye njengo-90% wamanje lapho izinga lokushisa lekhondatha yensimbi lingaphezulu kwezinga lokushisa lokusebenza elingu-30℃.Akunzima ukubona ukuthi izinga lokushisa lengxenye ye-conductor kagesi yezinto zensimbi iyisici esibucayi kakhulu kuzo zonke izinhlelo zokusebenza zayo.Lokhu kubalulekile emishinini engumshini.Ngoba okokusebenza kwemishini ngokuvamile kufanele kube kumazinga okushisa angama-80 ℃ endaweni yokusebenza.Uma izinga lokushisa lokugcina liku-30 ℃ noma 45 ℃ ngaphezu kwaleli zinga lokushisa, izinga lokushisa letheminali lingase lidlule ku-100℃.Kuya ohlotsheni lwezibonelelo kanye nezinto zokuhlukanisa ezikhethelwe izingxenye ezikhethiwe, izimpahla kufanele zisetshenziswe ngesikhathi esingaphansi kwesilinganiso samanje ukuze zikwazi ukusebenza ngokuthembekile ngaphakathi kwebanga lokushisa elifunekayo.Kwezinye izimo, izinto zokusetshenziswa ezifanele izingxenye ezihlanganisiwe ezipakishiwe ngeke zikwazi ukubala kahle izidingo zokususwa kokushisa, ngakho-ke amandla amanje ezingxenyeni ezinjalo zetheminali kufanele abe ngaphansi kakhulu kunowamanje olinganiselwe.
