Ukusetshenziswa kanye nezici zefeni elingaqhumi
Ifeni evikela ukuqhuma isetshenziswa ezindaweni ezinamagesi avuthayo neziqhumane ukugwema izingozi ezibangelwa izinto ezithile ezivuthayo neziqhumane.Abalandeli bokufakazela ukuqhuma basetshenziswa kakhulu ukufaka umoya, ukukhipha kanye nokupholisa izimboni, izimayini, imigudu, imibhoshongo yokupholisa, izimoto...Funda kabanzi -
Umehluko phakathi kwekhabhinethi yokusabalalisa amandla angaqhumi, ibhokisi lokusabalalisa amandla angaqhumi kanye nekhabhinethi yokushintsha ekwazi ukuqhuma
Kunemikhiqizo engaqhumi ebizwa ngokuthi amabhokisi okusabalalisa ubufakazi bokuqhuma kanye namakhabethe okusabalalisa okuvikela ukuqhuma, kanti amanye abizwa ngokuthi amabhokisi okusabalalisa izibani ezivimbela ukuqhuma, amakhabethe okushintsha angakwazi ukuqhuma, nokunye.Ngakho yimuphi umehluko phakathi kwabo?...Funda kabanzi -
Iyini iswishi ehlukanisayo engaqhumi ngaphansi komhlaba?uyini umphumela?
Isinqamuli (isinqamuli) sisho ukuthi uma sisendaweni engaphansi, kunebanga lokuhlukanisa kanye nophawu olusobala lokunqamula phakathi koxhumana nabo abahlangabezana nezidingo ezishiwo;uma isendaweni evaliwe, ingathwala okwamanje ngaphansi kwe-norma...Funda kabanzi -
Isiteshi sohlobo lwebhokisi
Isiteshi esincane sohlobo lwebhokisi sakhiwe ikakhulukazi amayunithi kagesi afana nesistimu yokushintshwa kwe-multi-circuit high-voltage, ibha yebhasi ye-armored, isistimu ye-automation ehlanganisiwe ye-substation, ukuxhumana, i-telecontrol, i-metering, isinxephezelo se-capacitance kanye nokunikezwa kwamandla ka-DC.Ifakwe i...Funda kabanzi -
Ushintsho olukhulu kuma-photovoltaics selufikile.Ubani ozoba ubuchwepheshe obulandelayo obujwayelekile?
U-2022 unyaka ogcwele izinselelo zomhlaba wonke.Ubhubhane lweNew Champions alukapheli ngokuphelele, futhi isimo esibucayi eRussia nase-Ukraine sesilandele.Kulesi simo samazwe ngamazwe esiyinkimbinkimbi nesiguquguqukayo, isidingo sokuvikeleka kwamandla kuwo wonke amazwe ...Funda kabanzi -
Umsebenzi kanye nomsebenzi wesethi yemishini kagesi ephezulu
Amathuluzi aphelele anamandla kagesi aphezulu (ikhabethe lokusabalalisa lamandla kagesi aphezulu) libhekisela kumshini wokushintsha we-AC wangaphakathi nangaphandle osebenza ezinhlelweni zikagesi ezinama-voltage angu-3kV nangaphezulu namafrikhwensi angu-50Hz nangaphansi.Isetshenziselwa kakhulu ukulawula nokuvikela izinhlelo zamandla (okuhlanganisa...Funda kabanzi -
Iyini i-oyili ecwilisiwe yokulawula ingcindezi uwoyela ocwilisiwe wokuzipholisa ongenisa isilawuli
Isilawuli esicwiliswe ngamafutha Isilawuli sokungeniswa kokupholisa esizifake ku-oyili Isicelo: Isilawuli se-voltage esingeniswayo singalungisa i-voltage ephumayo ngaphandle kwesinyathelo, ngokushelelayo nangokuqhubekayo ngaphansi kwezimo zomthwalo.Isetshenziselwa kakhulu ukuhlola ugesi nogesi, ukulawulwa kwezinga lokushisa kwesithando somlilo kagesi, i-rec...Funda kabanzi -
Ukuhlaziywa Nokuphathwa Kwezizathu Eziyisithupha Zokungalingani Kwe-Voltage Yohlelo Lwesinxephezelo
Isilinganiso sekhwalithi yamandla i-voltage ne-frequency.Ukungalingani kwamandla kagesi kuthinta kakhulu ikhwalithi yamandla.Ukwenyuka, ukuncipha noma ukulahleka kwesigaba samandla kagesi wesigaba kuzothinta ukusebenza okuphephile kwempahla yegridi yamandla kanye nekhwalithi yamandla kagesi yomsebenzisi ngamazinga ahlukahlukene.Kunezizathu eziningi ze-voltag...Funda kabanzi -
Isimo sokuthuthukiswa kwemboni ye-transformer yamandla, ama-transformer amandla okuvikela imvelo azonciphisa kakhulu ukulahlekelwa kwamandla
Isiguquli samandla isisetshenziswa sikagesi esimile, esisetshenziselwa ukuguqula inani elithile le-voltage ye-AC (yamanje) libe enye i-voltage (yamanje) enefrikhwensi efanayo noma amanani amaningana ahlukene.Kuyisizinda sikagesi kanye nesiteshi esincane.Enye yemishini eyinhloko yesikhungo.Okuluhlaza okuyinhloko ...Funda kabanzi
