Ukufinyelela Amaswitshini eLow kunye neMedium Voltage
Yini Ngoku Olandelayo Amaswitshini eLow Voltage?
Umbhikisi wevolenti engaphansi luchazwana amandla okusebenzeka kwi-volenti ezi-1,000 volts (V) AC noma i-1,500 V DC, esihle sikhetho nokuthola amaphethelo yamaphrofayela. Ukhutshane lokusebenza ngokupheleleyo lususa izinhlobo ezikhona ngokubanzi ngokukhombisa:
- Amaphetheli zasekhaya: Lezinye iindlela ezihlinzekileyo ezixhasa amakhomphu wekhaya kusukela ukusuka okanye umgibe wokuhlola.
- Amafuthesi: Bayegcwelwa njengezinto eziphathelayo ezifuna ukususa isikhala esiphakeme sokuqala lokusebenza ngenqanawe lwehlakalo kunye nokuhlola.
- Amakhontakha: Zisetshentiswayo kumakhomphu wekhaya yokuxhasa ukuhamba kwemfuyo wekhaya.
- Amaswitshini: Bahlola ukudibanisa kwezinhlobo zakhoze kwamakhomphu wekhaya, kuhlonipha ukubanjwa noma ukufinyelela.
Ukuthi i-low voltage switchgear isenjini yicala ngokuthi lisebenzisa ukufaka lesilowo sokumoya esihlanganisweni lokuphelele abalimi basekhaya, imibhodi yesithathu, kunye nolwandle lwesayensi elincane. Lomsebenzi kulungileyo nokusetshenziswa kwiseva esidingayo.
Ukufunda Amagama Akhethi leSwitchgear eNgenini
I-switchgear yenye ivoltage enye ekhona phakathi kwe-1 kV kunye ne-38 kV, uhlobene nesiwo esidingayo ezindaleni zokugcina nokusebenza. Iphakamishwe ngamagama okuthuthukiseyo othe ithathe izindlela ezidingayo kwi-indawo yokuphucula:
- Ubuhle Bokubuyela Ukusuka Kwesikhephe : Ikhathalela isenzo sokuqinisekisa ukuba lokhu kuhlelwa ukuze alibaleke amandla elekhetikali wakhiwe kuqhathaniswa.
- Ubungako Besiqiniseko : Ugcinwe ukuthi amaphutha amanqaku kuhluke amandla esetyenziswa ngokubanjwa emasinyeni wesithunzini.
- Isilimela Sabozi Somncedisi : Ukusetyenziswa kwiqhutywa lokuncane kulandelwe ukuba uhlale kakhulu ngamabomvu abaningi, okufakelwa ukuphucula izinto zokusebenza ezindabeni.
Ngemva kokwesiphi, umthwalo womoya wombili wokuqala ulayishwa ngokungakho amaxhobo omncane njengamaphrojeketi nokuthi zizama ukubuyekeza uphawu lwesicwangciso. Le zonke izindlela zihlelwe ukuthola ukudibanisa ngokukhona kunye nokuthola ukususa nokuhlola kwezinto zokusebenza komoya ezincedwayo kakhulu.
Izinkinga Nezifundo Ezikhoyo
Umbhodwana wokuphila nokusetyenziswa kwezilungiselelo
Izicomponekhi ezisetyenziswa kwi-low voltage switchgear zinikelayo emahlukeni amacala njenge-plastic nge-aluminum, izikhishwa ngasinye ukuthi zihlabeleke umthengiso wenkululeko esibonakalisiyo lokusebenza kweelektri khona eliphantsi. Lokhu luhlukekile ne-medium voltage switchgear, okufuneka amacala angakhulu kabi njenge-steel nokulungiselela okukhangelwe ukuze asetselele amandla amakhulu amahhovoloti. Ukusetha kwezilungiselelo lokhu lungeza ukudibanisa kodwa luvavanye imithetho eziphumaphi ezifanele nge-voltage engakho.
Amazilinganiso wokulungiselela nokuchasene kwe Sistema
Amaphethi wemfundo yezolo lavela ngokwesiqephu isibonelo esisetyenziselwe njenge-amathuba, okuyingxenye yokuhlola ukusetyenziswa kwamaphethi wezolo eluningi. Ngaphezu kwalokho, amaphethi wemfundo wesibili usetyenziswa ngokubanzi ngezinto ezidingekayo lokuhlola, njengesi-gas-insulated switchgear (GIS) okanye i-oil-insulated configurations, ukuze kuhlola izicwangciso ezingqeni zokusebenza elektriki. Ukuthi kudinga amanani aphantsi ahlola kakhulu kungaba kuhlonipha ukuthi kudinga umphumela omncane wokuqhathanisa kumaphethi wesibili. Amasistimu akhona ayisebenzisanga ukukhokha amaphethi okanye ukufinyelela nokuthi bafinyelele kuwo, futhi babhekisele ukuphatha konke abalulekileyo njengama-line capacitance kunye ne-inductance. Ngakho ke, ukusetshenziswa kwezindlela ezincinci zokubaleka nokudibanisa kuhlanganisa imiphumela nemfanelo ye-medium voltage switchgear solutions, ukuze bayenza indlela engcono kakhulu ekusetyenzisiwe yi-high-demand setups.
Amavuselelo Okusebenzayo Njengamanje neZikhatsi Zokusebenzela
Ukusebenziswa Kwesayithi kunye neSektori Sesayithi
Umsebenzi wokugcina ampefu angaphakathi akusetyenziswa ngokuphi ndawonye kwiindustri yamandla noma ezifundekwini nokuthi kuzikhona eziphakathi zomndeni, ngokukholelwa kwesintu sokulandelana nokuhlola iiphasi eliphambili lokusebenza. Ukukholelwa kwegcino kuningi ukuthi kungaba phakathi komsebenzi apho akudingekanga umsebenzi omphambili, futhi ukuhlala kwenzelelo lwezinto ezidingekanga. Ngakwesinye, umsebenzi wokugcina ampefu angaphezulu akusetyenziswa ngokubanzi kwiisayithi lezombuso nokulandelana okubanzi kwiindawo zokusebenza, apho kukho umsebenzi omphambili nokukhonzwa kuhloniphepha. Umsebenzi wokugcina ampefu angaphezulu ukuthi kufanele ukulandelana nokuhlola iiphasi eliphambili lokusebenza, apho kukho umthengiso nokuhlola iiphasi eliphambili lokusebenza, apho kukho umthengiso nokuhlola iiphasi eliphambili lokusebenza. Ngokusebenzisa izibalo eziningi, kubonakali ukuthi iindlela zakugcina ampefu angaphezulu zihlanganise ukungabiko amasomo aokushesha. Ngokungahluhlaza umthengiso lokuhlola iiphasi eliphambili lokusebenza, bayenza ukuthi iindlela ezidingekanga zikwazi ukukhathalisa imininingwane yesebenti.
Imininingwane Yokuhlola Iiphasi Ekumandleni Kwemfundo
Kuqhopho lwezindlela, umthwalo wokuphucula okuncane lwaphinda ukuthi litshintshisi lokuhlola iindlela zokufundiswa kanye nezinye izinto ezindaweni. Amalayithi akho amacala amaphindaphinde ahlukile ngokubanzi kumahluko omdalu, ukuze libheke ngokukhululekile apho kukhona imigomo eliphakamisileyo ezifanayo kwiindlela ezidingekayo ezindaweni ezinomsindo. Kodwa, njengoba sizizukulwazi kanye nokuzama kokuphucula kwemikhombo yezindlela, umthwalo wokuphucula womdali waphinde ukuthi wenza isenzo esingabhekisele. Lento lingakwazi kakhulu phakathi komkhulu omphakathi wakwesikhashana sokugcina ukusetyenziswa kwemondolozi wesiqhelo futhi ukusetha ngeendaweni ezincane ezinathintela izimdlwano ezingasihlangene. Ngokuhlawula amatekonithi, leli sisekelo seliyongeziya uhlobo olunyelekileyo lokusebenza kwezindlela ngokungafanelekanga kunye nokusetshentlisa ukusetyenziswa kwemondolozi wesiqhelo. Imsizi yesiqhelo esilungileyo singahlanganisa ukuthi kulungiselelwanga lokusetyenziswa kweenergy futhi ukuthi usetyenziswa kwenkulunkulu kanye nokuhlola kahle kwezindlela ezindaweni zezikhashana.
Amagcali AkwiNgcwadini Ngenxa YokoKukhuthaza
Ukuthenga Okusondezwayo vs Izinkinga Zokugcina Kwesikhatsi Esikhulu
Izicwangciso zokuphucula kumthetho wokususa ngokulandelayo kunye nokungaphakathi olwandle (MV) ukuthi uqondise phakathi kwesikhashana sokubonisa ngezinye izinto ezinamagugu neziyenzelwe. Ngokushesha, isithuthi sokuqala sesi-low voltage (LV) sihluke kakhulu, esikhankanyisweni lokuhlola amaxesha. Okuningi, kufanele usuke usibuyeleyele umemfiswano wesintu ngezihlabelelo ezahlukene ezingabizwa ngalokhu okudingeka ukuthi akho amandla apha apho amandla angavalekile kakhulu emva kokusebenza, okungakungapheliyo ukuthi uzoba amandla angavalekile kakhulu ngokugcina izinkampani zomphilo. Ngokugcineneyo, xa MV switchgear ikususa imali engaphezulu kakhulu, iimboniso zingahluke kakhulu ngokuthi zizama ukuba zidibanise amandla amanqaku kunye nokuziphindaphinda kwezifuno, okungakungapheliyo ukuthi uzoba amandla angavalekile kakhulu ngokugcina izinkampani zokusebenza emva kokusebenza. Ngakho ke, izimbongi zezinhlanga ezidinga ukubuyela imali endaweni yokubona kufanele bazame ukubuka kwezilimi eziningi, ukubonelela amagugu angasetyenziswa kunye nokuhlinzekiswa kwezinkampani kunye nokusebenza ngaphandle komsebenzi womphilo wesithuthi.
Amalungisiwe wosafeti nezinto ezinethuthukiswa
Ukufolofola ngeamandla okuziphathelene nokuhlola kwezindaba ezinethunywa zikhoyo lapho sizoqinisekisa ngakwesobizo lomphawuli wesayithi neomsulungu. Izinkinga zakho zidlule ukuba zibhalisiwe ngezindaba ezintathu eziqhathaniswayo njenge-IEC ne-ANSI ukuze ziqinisekise amandla nokususa ukubhekisisa izikhoho. Ukuphatha kakhulu kanye nokufinyelela kakhulu ngeemithetho yezinhlobo zokuthuthukisa zikhoyo zingakho esenzakalo ukucabanga ukuthi iindlela zikahle zihlanganise ukubuyiselwa kwezinsimbi ezifanele, lokhu okungavunyelwe kunoma imali engakho emangweni. Ngakho ke, ukufundiswa kwabantu ababenzi kwezinto ezizokuthuthukisa zikhoyo zingakho esenzakalo ukusebenzela nokuhlola kuhluke kanye nokuthuthukisa komphawuli wesayithi. Ngokusetyenziswa kwesikhwama, izifundiso zidinga ukuba zibheke izinkozo zabo nokuthi ziziprotekise amandla nokumona wabo, futhi uzokusetyenziswa nokuhlola nokufolofela ngezindaba zezilimi ezinethunywa nezingaphezu-kwabo. Lento yokudlula kakhulu akhuphi ukuthi sikhlone ukusuka kwezinhlobo zokuthuthukisa kodwa sikhupha ukusuka kwezinhlobo zokuthi izidinga zombuso nezingaphezu-kwabo. Okuningi lokhu kuhlanganisa ukuthi umphawuli wesayithi usuke usuku sikhona kanye nokuthi izidinga zombuso zikhona nokuhlola nokuhlola kwezinhlobo.
