Ukubhalaka Ukuphindepha Okusebenza Olukhulu Encane Ngephandle Okusebenza Olukhulu Ngaphakathi

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:

1. Amaphetheli zasekhaya: Lezinye iindlela ezihlinzekileyo ezixhasa amakhomphu wekhaya kusukela ukusuka okanye umgibe wokuhlola.
2. Amafuthesi: Bayegcwelwa njengezinto eziphathelayo ezifuna ukususa isikhala esiphakeme sokuqala lokusebenza ngenqanawe lwehlakalo kunye nokuhlola.
3. Amakhontakha: Zisetshentiswayo kumakhomphu wekhaya yokuxhasa ukuhamba kwemfuyo wekhaya.
4. 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:

1. Ubuhle Bokubuyela Ukusuka Kwesikhephe : Ikhathalela isenzo sokuqinisekisa ukuba lokhu kuhlelwa ukuze alibaleke amandla elekhetikali wakhiwe kuqhathaniswa.
2. Ubungako Besiqiniseko : Ugcinwe ukuthi amaphutha amanqaku kuhluke amandla esetyenziswa ngokubanjwa emasinyeni wesithunzini.
3. 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

Iingxenzo kwimeko ephantsi yenqanaba lekugcinwa kwiindlela encinci njengeplastiki kunye ne-aluminum, zinika kwawo umkhubo wokuxhasa izixhobo eziphambene nezixhobo zokuxhasa zokugcinwa. Iindlela zenqanaba phantsi zibonisa ingxelo enye - kufuneka zisebenzise izixhobo eziphezulu njengestele kunye neemveliso eziphambene nezixhobo ukuba zenze ngokuchanekileyo nezixhobo ezinkulu zokuxhasa. Ukukhetha lezi zixhobo eziphezulu akukho kuphela ngokuba zilinda ngemva kwexesha elide - ziyafumanisa ngokwenyani iingxaki ezijayelekayo apho kusebenza ngaphezulu kwenqanaba lekugcinwa. Xa kudiselwa imeko yenqanaba lekugcinwa, abasebenzisi bamekela ngokuqhelekileyo indlela aya kuxhasa ngokuxhasa nokuxhasa okuphambene nezixhobo ezifana nezixhobo ezifana nezixhobo zokugcinwa aphantsi kwenqanaba. Le ndawo kuyahlukile kakhulu kwiindlela zokufaka apho kufuneka ubumfobo bokugcinwa buqinisekiswe ngaphezu kwezixhobo zokusebenza.

Amazilinganiso wokulungiselela nokuchasene kwe Sistema

I-Switchgear esebenza ngemikhwelo ephansi iqhubeke ngokusebenzisa izinsiza zokulinganisa ezinhle, okungenani isebenza ngokuthokozisa amagapu esize esikhethe ngokuthi aziyasebenzela kahle kule miqomo ephansi. Uma sikhula kumagrade yemikhwelo enhle, loko ke siphelile kahle. Abasebenzisa kumele baphumelele izindlela eziphambene nezinsiza zokulinganisa, ngokweqile kuzo i-GIS (izinsiza zokulinganisa zengesi) noma izinhlelo zokudla ezijwayelekile. Kungani? Ngokuba i-Switchgear yemikhwelo enhle iyasebenzela ngamandla amakhulu kuneza yemikhwelo ephansi. Amakhampisi angenani ayingqelwa ngale ndlela yokulinganisa engaphambili ukuthokozisa ukuthi kugcwalwe amakhawula ngokuphelele xa kunezinkinga, futhi ukuthokozisa ukuthi kuzozidwa izinkinga ezijwayelekile ezixhoshwa ngekhwelo kanye nezindlela zokuxhuma. Futhi musa ukulahla konke okuqukethwe kwezilwane zokulandela ezifakwe ngoku. Lezi zindlela ezinhle zenza i-Switchgear yemikhwelo enhle ngumdingiso omkhulu kakhulu kuzo zonke izifunda zokwenza apho ukubaluleka kubalulekile kakhulu.

Amavuselelo Okusebenzayo Njengamanje neZikhatsi Zokusebenzela

Ukusebenziswa Kwesayithi kunye neSektori Sesayithi

Iswitchgear yemvoltage ephezulu isebenziswa kakhulu kumaqhekeka amancane, imicimbi yemiservice, kunye nezindlu zokuhlala ngokuba ingaba yimelela ukwahlulwa kwezixhobo ngaphaya kwezimali. Le ndeke zisebenza ngokugqibelela xa kungakho imvume encane yemvoltage, oku kwenza yinto ecaqulwa ngokupheleleyo kuzo zonke izindlela zokusebenzela. Ngokwemva, iswitchgear yemvoltage yemaphakathi isebenziswa ngokuvamile kumaqonga amaphakathi kunye nezindawo zokwenza izinto aphakathi kwezixhobo kunye nokusebenza okupheleleyo. Iindleke zemvoltage zemaphakathi zisebenzisa amaqela amaphakathi kunye nezixhobo zokusebenza zokugqibela ngaphandle kwezinto ezingafanele. Xa sibona ukusetyenziswa kwezinye iindleke kwezinye izifundo, sibona ukuba ngokuguqula kwiindleke zemvoltage yemaphakathi kuncipha ukungcola kwezixhobo ngama-30% kakhulu. Okusebenza ngokupheleleyo kwenza ukuba izindawo zokwenza izinto zifumane ukuthi zidinga kwi-grid ngokupheleleyo, ngaphandle kwezixhobo ezifanele zokungcola kwezixhobo ezithintana nezinkqubo zokwenza izinto.

Imininingwane Yokuhlola Iiphasi Ekumandleni Kwemfundo

Iswitchi lemvoltage lephantsi libaluleke kakhulu kumathuluzi wezimali xa kufundiswa ukusebenzisa imiphumano yokudlala. Ngokuthi lezi zinhlelo zingasetshenziswa ngendlela eziningi zoba kusebenza ngendlela efanayo nezindleko ezahlukahlukene, okwenza kube yimali yokuthola kakhulu kuzindleko ezahlukahlukene. Kodwa izinto zingashintsha xa izindlu zezimali zingaphezulu kanti zidinga amandla aphezulu. Lapha-ke iswitchi lemvoltage phakathi isuka. Izinhlanganisela ezinkulu kudinga okunye ukuphatha amandla nokuqinisa ukuthenjelwa kwayo ngokuphelele kuzinhlelo zemali ezinhle. Xa ukuchazwa okuhle kuhlanganiswa kulezi zinhlelo, izindlu ziba yimali ngokungcono. Ukulandwa ngokushesha kuvumela abasebenzisi ukubona ngqo ukuthi amandla uyasebenzisa kanjani noma lutho. Iswitchi esihle sengcina amandla ngendlela ebono, futhi kuyasebenza ngendlela yokuthola amali futhi yenze ukusebenza kuzindleko zonke ezifanayo.

Amagcali AkwiNgcwadini Ngenxa YokoKukhuthaza

Ukuthenga Okusondezwayo vs Izinkinga Zokugcina Kwesikhatsi Esikhulu

Xa khesha lokhetha phakathi kweqile kanye neqile ephakeme (MV) izixhobo zokugcina, izinkampani kufanele bheke kakhulu kwezindleko zabo ngokwokuqala nasekupheleni kwesikhatho sokufaka. Izixhobo zeqile ezingaphansi kungaba nemali encane xa zifakwa kwanokuqala, ngoko ke amanye amakhono alandela le ndleko ukuthola ikhono lokuncipisa imali ngokuqala. Kodwa lapha kukho indaba enqunqweni - le ncamathisano ngamaqela ayadlula ngokushesha ngoba le ndlela zingaba zinexesha ezingcono kwaye zingase kudale ngaphambi kokuba kudinga ukuvuselelwa ngokukhulu. Ngelishwa, izixhobo zeqile ephakeme zingaba nezindleko eziphezulu ngokwokuqala. Kodwa, abasebenzisi babize ukuthi le ndlela zingaba zingena ngokushesha kwaye zingase kuthande kakhulu ukusebenza ngokuthuluthu. Ngemva kweminyaka engama-5 noma engu-10, le nqabile ngamaqela ayadlula ikhono lokunceda imali nangona ukuthenga kungaba kungapheliwe. Kuye kuba nokwenzeka ukuthola ikhono lokunceda imali, ukubheka konke le ndawo ngokucacileyo kungaba yindlela engcono ukuba kungasebenzi kuphela kakhulu kwezindleko xa kuthengwa ngokushesha.

Amalungisiwe wosafeti nezinto ezinethuthukiswa

Imithwalo yesafethi nezimfuneko zokulandela kudinga kakhulu xa kufika kweqabi lezimali (LV) neqabi lezimali edlule (MV). Lezi sistimu zidinga ukwanelwa izindlela zangempela ezifana nezokuvumelana ne-IEC ne-ANSI uma kudingeka zisebenze ngendlela esafetha ngeke yenze imiphumo. Izivivinyo ngokohlelwa nasebenzela yonke lezo mithwalo yokulandela iyasiza ukuthiwa kwehlise imisebenzi kwezindawo zokusebenza iyasiza ukuthiwa kwehlise amathimelela ekusebenzeni nazo, okwenza izindleko ebalulekile kumaqo xa kusebenza. Ukuqina kudinga futhi. Abasebenzi bakwazi lezo mithwalo yokulandela esafethi baphumelela kahle ukusebenza nekuhlela izivivinyo zeqabi lezimali. Iindlela ezakhona ukuthiwa zisethembeni izindlela zokuqina kwezimpilo nezokusebenza zokulandela kudinga ukuthiwa kube lula ukulandela izimfuneko zangempela nezilandelayo. Lo msebenzi wonke kwezindlela zokulandela uyenza izindawo zokusebenza zibe yimali futhi zilinde isithunzi samandla ngokuphelela kakhulu kunesithunzi esingaphansi kwezinyanga ezimbalwa.
