Kuphi futhi Kungani Kufanele Ufake Iswishi Yokuhlukanisa Umthwalo Kumaphaneli Kagesi

Ukuphepha kukagesi kanye nokuthembeka kokusebenza kuyizinto ezibaluleke kakhulu ezinhlelweni zokusatshalaliswa kwamandla zanamuhla. Izakhiwo zezimboni, izakhiwo zezentengiselwano, kanye namaphrojekthi engqalasizinda athembele kumaphaneli kagesi ukuze asabalalise ugesi kahle emithwalweni nasemishinini ehlukahlukene. Kodwa-ke, ukulungiswa okuvamile, ukushintshwa kwemishini, kanye nokuxazulula izinkinga kudinga indlela ethembekile yokunqamula ugesi ngaphandle kokudala izingozi zokuphepha.

Yilapho-keUkushintsha Ukuhlukaniswa Komthwaloiba yingxenye ebalulekile. Ivumela ochwepheshe ukuthi bahlukanise ngokuphephile imithwalo kagesi ekuhlinzekweni kwamandla, okuqinisekisa ukuthi ukulungiswa kungenziwa ngaphandle kokunikezwa amandla ngengozi. Ukuqonda kahle umsebenzi wayo kanye nezindawo ezifanele zokufaka kungathuthukisa kakhulu kokubili ukuphepha nokusebenza kahle ezinhlelweni zikagesi.

1. Ukuqonda Umsebenzi Oyinhloko Weswishi Yokuhlukanisa Umthwalo Ezinhlelweni Zikagesi

Inhloso eyinhloko yeswishi yokuhlukanisa umthwalo ukunqamula imishini kagesi ekuhlinzekweni kwamandla ngenkathi isekethe ithwala amandla ayo ajwayelekile okusebenza. Ngokungafani nama-isolator ayisisekelo okumele asebenze kuphela lapho isekethe isivele iphelelwe amandla, i-Ukushintsha Ukuhlukaniswa Komthwaloyakhelwe ukuphazamisa ngokuphephile amandla omthwalo ngesikhathi sezimo zokusebenza ezijwayelekile.

Lo msebenzi uhlinzeka ngendawo ecacile nephephile yokunqamula phakathi kokunikezwa kukagesi nemishini. Uma iswishi ivaliwe, iqinisekisa ukuthi amadivayisi angaphansi komfula ahlukaniswe ngokuphelele nomthombo wamandla.

Ezinhlelweni eziningi zokusatshalaliswa kwamandla, izinkinobho zokuhlukanisa zisebenza kanye nezinkinobho zokuhlukanisa kanye namanye amadivayisi okuvikela. Ngenkathi izinkinobho zokuhlukanisa zisingatha ukuvikelwa kokulayisha ngokweqile kanye nokwehlukaniswa kwesekethe, izinkinobho zokuhlukanisa zinikeza ukulawula kokusebenza kanye nokunqanyulwa okuphephile kwezinqubo zokulungisa.

2. Izindawo Ezibalulekile Kumaphaneli Kagesi Lapho Kufanele Kufakwe Iswishi Yokuhlukanisa Umthwalo

Ukufakwa kwamaswishi okuzihlukanisa ngendlela ehlelekile kusiza ekuthuthukiseni ukuphepha kanye nokulula kwezinhlelo zikagesi.

Iphuzu elilodwa lokufaka elivamile yi-ibhodi lokusabalalisa eliyinhlokoUkubeka iswishi yokuhlukanisa ugesi endaweni kagesi engenayo kuvumela opharetha ukuthi banqamule ugesi kuyo yonke iphaneli uma kudingeka ukulungiswa noma ukuvalwa okuphuthumayo.

Enye indawo evamile ingaphakathiamaphaneli okusabalalisa okuncaneezihlinzeka ngogesi ezindaweni ezahlukene zesakhiwo noma isikhungo. Lokhu kusethwa kuvumela ochwepheshe ukuthi bahlukanise izingxenye ezithile zesistimu ngaphandle kokuvala yonke inethiwekhi kagesi.

In amakhabhinethi okulawula ezimboni, amaswishi okuzihlukanisa avame ukufakwa ngaphandle komnyango wekhabhinethi. Leli lungiselelo livumela opharetha ukuthi banqume ugesi ngaphambi kokuvula ikhabhinethi, okunciphisa ingozi yokuchayeka ezingxenyeni zikagesi eziphilayo.

Izinhlelo zamandla ezisekelayo, njengokufakwa kwejeneretha noma izinhlelo zokushintsha okuzenzakalelayo, zingafaka nezinkinobho zokuhlukanisa ukuqinisekisa ukulungiswa okuphephile nokuhlolwa kwemishini.

3. Izinzuzo Zokuphepha Zokusebenzisa Iswishi Yokuhlukanisa Umthwalo Ngesikhathi Sokulungiswa Nezimo Eziphuthumayo

Imisebenzi yokulungisa ugesi ihilela izingozi ezinkulu zokuphepha, ikakhulukazi lapho kubhekene nezinhlelo zamandla aphezulu noma zamandla aphezulu. Ukunikezwa amandla ngengozi ngesikhathi sokulungiswa kungabangela ukulimala okukhulu, umonakalo wemishini, noma isikhathi sokungasebenzi.

Ukufaka i-Ukushintsha Ukuhlukaniswa Komthwalokusiza ukunciphisa lezi zingozi ngokuhlinzeka ngendawo yokuxhuma ethembekile phakathi komthombo wamandla nomthwalo kagesi. Lokhu kuqinisekisa ukuthi abasebenzi bokulungisa bangasebenza ngokuphephile emishinini kagesi ngemva kokuba iswishi ivaliwe.

Izinkinobho eziningi zokuhlukanisa nazo ziyasekelaukukhiya/ukuthega (i-LOTO)izinqubo. Lokhu kuvumela ochwepheshe ukuthi bakhiye iswishi endaweni ethi OFF futhi banamathisele amathegi esixwayiso, okuvimbela ukuxhumana kabusha okungagunyaziwe noma okungahleliwe ngenkathi kwenziwa umsebenzi wokulungisa.

Ezimweni eziphuthumayo, ikhono lokuhlukanisa ugesi ngokushesha nalo libaluleke kakhulu. Abaqhubi banganqamula imishini ngokushesha ukuze bavimbele umonakalo owengeziwe noma banciphise izingozi ezifana nokushisa ngokweqile, amaphutha kagesi, noma izingozi zomlilo.

4. Izici Zobuchwepheshe Ezibalulekile Okufanele Uzicabangele Lapho Ukhetha Iswishi Yokuhlukanisa Umthwalo

Ukukhetha iswishi yokuzihlukanisa efanele kudinga ukuhlolwa ngokucophelela kwezici eziningana zobuchwepheshe.

Into yokuqala okufanele icatshangelwe yileisilinganiso samanje kanye ne-voltageIdivayisi kumele ifane noma idlule izidingo zokusebenza kohlelo lukagesi ukuqinisekisa ukusebenza okuphephile ngaphansi kwezimo zomthwalo.

Iinani lezinsikaesinye isici esibalulekile. Izinhlelo zikagesi zezigaba ezintathu zivame ukudinga ukushintshana kwezinsika ezintathu noma ezinezinsika ukuqinisekisa ukuthi wonke ama-conductor anqanyuliwe ngokuphelele ngesikhathi sokuhlukaniswa.

Amandla okumelana ne-short-circuit nawo kufanele acatshangelwe. Ngisho noma izinkinobho zokuhlukanisa zingezona amadivayisi avikelayo ngokuyinhloko, kumele zikwazi ukubekezelela izimo zamaphutha kuze kube yilapho amadivayisi avikelayo esebenza.

Indlela yokufaka ingenye into ethinta ukwakheka kwesistimu. Amaswishi okuhlukaniswa angafakwa kumaphaneli, afakwe ku-DIN-rail, noma ahlanganiswe kuma-assembly e-switchgear kuye ngohlelo lokusebenza kanye nokucushwa kwephaneli.

5. Izindinganiso Zokufaka Nokuthobela Imithetho Yezinkinobho Zokuhlukanisa Umthwalo Ezinhlelweni Zamandla Zanamuhla

Ukufakwa okufanele kubalulekile ukuqinisekisa ukuthembeka nokuphepha kwamadivayisi okuhlukanisa ugesi. Onjiniyela bakagesi kanye nabafaki kumele balandele imikhuba yokuxhuma izintambo enconyiwe, izimvume zokufaka, kanye neziqondiso zomkhiqizi.

Ukufakwa kwamalebula acacile amaswishi okuhlukaniswa nakho kubalulekile ukuze opharetha bakwazi ukubona ngokushesha indawo yokulawula efanele ngesikhathi sokulungiswa noma izimo eziphuthumayo. Ngaphezu kwalokho, amaswishi kufanele afinyeleleke kalula futhi abekwe ngokuhambisana nezindinganiso zokuphepha zikagesi.

Ukuhambisana nezindinganiso zomhlaba wonke ezifana nezidingo zemishini ye-IEC kanye nemithethonqubo yokuphepha kagesi kusiza ukuqinisekisa ukusebenza okuqhubekayo kanye nokusebenza okuphephile.

Ukuhlolwa nokuhlolwa okuvamile kufanele kufakwe ezinhlelweni zokulungisa. Izingxenye zemishini kanye nokuxhumana kukagesi kungase kuguge ngokuhamba kwesikhathi, ngakho-ke ukuhlolwa njalo kusiza ukuqinisekisa ukuthi indlela yokuzihlukanisa iyaqhubeka nokusebenza kahle uma kudingeka.

Isiphetho

Ukuhlukaniswa kwamandla okuthembekile kuyimfuneko ebalulekile ezinhlelweni zikagesi zanamuhla. Ngokuvumela opharetha kanye nochwepheshe ukuthi bakhiphe imishini ngokuphephile ekuhlinzekweni kwamandla, izinkinobho zokuhlukaniswa zisekela imikhuba yokulungisa ephephile futhi zithuthukise ukuthembeka kohlelo lonke.

Uma ifakwa ezindaweni ezifanele njengamabhodi okusabalalisa amakhulu, amaphaneli amancane, kanye namakhabhinethi okulawula ezimboni, amaswishi okuzihlukanisa ahlinzeka ngendlela ewusizo nephumelelayo yokuphatha ukuphepha kukagesi kanye nokulawula ukusebenza ngaphakathi kwamanethiwekhi okusabalalisa amandla.

Imibuzo Evame Ukubuzwa

1. Iyini injongo eyinhloko yeswishi yokuhlukanisa umthwalo?
Isetshenziselwa ukunqamula imishini kagesi ngokuphephile ekuhlinzekweni kwamandla ukuze ukulungiswa nokulungiswa kwenziwe ngaphandle kwengozi yokushaqeka kukagesi.

2. Ingabe iswishi yokuhlukanisa umthwalo ingathatha indawo ye-circuit breaker?
Cha. Ama-circuit breaker ahlinzeka ngesivikelo ekuthwaleni ngokweqile kanye nama-short circuits, kuyilapho ama-isolation switch enzelwe ikakhulukazi ukunqamula okuphephile kanye nokuhlukaniswa kokugcinwa.

3. Ingabe izinkinobho zokuhlukanisa ziyadingeka kumaphaneli kagesi ezimboni?
Eziningi zezicelo zezimboni, ukushintshana kokuhlukanisa kunconywa kakhulu noma kuyadingeka yizindinganiso zokuphepha ukuqinisekisa ukuthi imishini inganqanyulwa ngokuphephile ngesikhathi sokulungiswa.
