I-YSM6-12/24 iyunithi yohlobo lwe-SF6 RMU ene-SF6 yokushintshwa komthwalo njengokushintshwa okuyinhloko, iKhabhinethi yonke ilungele ukusatshalaliswa kukagesi okuzenzakalelayo kanye nensimbi enwetshiwe evala i-switchgeart Itcharacters esakhiweni sayo esilula, ukusebenza okuguquguqukayo, ukukhiya okuthembekile kanye nokufaka okulula njll, okungahlinzeka ngamaphrojekthi wobuchwepheshe agculisayo womabili. ezikhathini ezihlukene zohlelo lokusebenza nabasebenzisi.Ngokwemukelwa kobuchwepheshe bezinzwa kanye nokudluliselwa kokuvikela kusesikhathini samanje, kanye nobuchwepheshe obuthuthukisiwe kanye nephrojekthi yokuhlanganisa eguquguqukayo.
Xhumana nathi
I-YSM6-12/24 iyunithi yohlobo lwe-SF6 RMU ene-SF6 yokushintsha umthwalo njengokushintshwa okuyinhloko, iKhabhinethi yonke ilungele ukuzenzakalelayo kokusatshalaliswa kukagesi futhi icwecwe futhi i-switchgear yensimbi enwebekayo. Ibhala ngesakhiwo sayo esilula, ukusebenza okuguquguqukayo, ukukhiya okuthembekile nokufakwa okulula njll., okungahlinzeka ngamaphrojekthi wezobuchwepheshe agculisayo kokubili ezikhathini zokufaka izicelo ezahlukene kanye nabasebenzisi. Ngokwamukelwa kobuchwepheshe bezinzwa kanye nokudluliselwa kokuvikela kusesikhathini samanje, kanye nobuchwepheshe obuthuthukisiwe kanye nephrojekthi yokuhlanganisa evumelana nezimo.
I-C YSM6-12/24 iyunithi yohlobo lwe-SF6 RMU ingahlangabezana ngokuphelele nemfuneko yemakethe eguquguqukayo eqhubekayo. Kungathatha i-SF6- 12/24 ekhiqizwe i-switch break break; Izindlela zokusebenza zeswishi eyinhloko ngaphakathi kweyunithi eyinhloko yeringi zingaqhutshwa ngesandla noma ngamandla kagesi. Futhi ingahlangabezana nemfuneko "Yokulawula Okune" uma ifaniswe ne-FTU ne-RTU.

1. Shintsha isinqamuleli
2. Ukuvikelwa kwe-Fuse-switch
3. Ukuvikelwa kwe-circuit-breaker
4. Ukulinganisa kwe-MV
5. Amakesi (Iphaneli yebha yebhasi)
2. Ukuvikelwa kwe-Fuse-switch
1. shintsha isinqamuli seswishi se-cubicle kanye neswishi yokubeka umhlaba endaweni ebiyelwe egcwele i-SF6 futhi eyanelisayo.“i-sealed pressure system ” izidingo.
2. I-cubicle yebha yebhasi yonke endizeni efanayo evundlile, ngaleyo ndlela ivumela izandiso zebhodi lokushintsha kamuva nokuxhumeka kumathuluzi akhona.
3. I-cubicle yokuxhuma ifinyeleleka ngaphambili, ukuxhumana nesinqamuleli seswishi esingezansi namatheminali amaswishi e- earthing (ama-IM cubicle) noma izibambi ze-fuse ezingezansi (ama-PM ne-QM cubicle). Leli gumbi libuye lifakwe i-
ukushintshwa kwe- earthing ezansi nomfula kusuka kumafuse e-MV amayunithi okuvikela.
4. indlela yokusebenza, ukuhlangana kuqukethe izakhi ezisetshenziselwa ukusebenzisa isixhumi se-switch kanye neswishi ye-earthing futhi isebenze okuhambisanayo.
izinkomba (ikhefu elihle).
5. I-cubicle yamandla kagesi aphansi (isakhiwo esibiyelwe esingenhla nesingezansi) ukufakwa kwe-a
i-terminal block (uma inketho yemoto ifakiwe), amafuse e-LV namadivayisi axhumene adluliselwe. Uma kudingeka isikhala esengeziwe, indawo ebiyelwe eyengeziwe ingase yengezwe phezu kwe
i-cubicle.
6. Ama-switch cubicles (IM) angakhethwa futhi angafakwa: control motorization;
ama-surge arresters.
Ukuxhumana okujikelezayo kwezigaba ezintathu kufakwe egumbini legesi eligcwele igesi ye-SF6 futhi ukucindezela okuhlobene kungu-0.4bars. Inokusebenza okuhle kakhulu kokusebenza ngokuphepha nokuthembeka.
● Ukuqina:
Igumbi lomoya ligcwele igesi ye-SF6, ehlangabezana nezidingo ezijwayelekile ze "isistimu yokucindezela evaliwe", nokusebenza kokuvala kuhloliwe futhi
ihlolwe efektri.
● Ukuphepha Kokusebenza:
1. Iswishi inezindawo ezintathu zokuthi "valiwe", "vula" kanye "nesisekelo", futhi ine
umsebenzi wokukhiya ukuvimbela ukusebenza ngengozi. Oxhumana naye uqhutshwa ukuzungezisa
indlela yokugcina amandla entwasahlobo, engathinteki izici zokusebenza komuntu.
2. Inemisebenzi ethi "break" kanye neyodwa.
3. Amandla okwenza i-short-circuit ye-SF6 grounding switch ihlangabezana nezidingo ezijwayelekile.
4. Uma kwenzeka ingozi, ingcindezi iyehla ngemva kokuba igesi ye-SF6 ecindezelwe ngokweqile ibhodloze i-diaphragm yokuphepha, futhi igesi izofuthwa ngokuqondile ngemuva kwekhabhinethi ukuze iphephe.
Ukwephula Isimiso:
Igesi ye-SF6 inokusebenza okuhle kakhulu kokucisha i-arc. Lapho inkinobho ivuliwe, ukunyakaza okuhlobene phakathi kwe-arc negesi kuzocisha i-arc. Lapho othintana nabo abahambayo nabamile behlukaniswa, i-arc ivela emkhakheni we-electromagnetic okhiqizwa uzibuthe ongunaphakade, futhi i-arc iyabonakala.
side futhi sicime lapho yamanje iwela uziro ngegesi ye-SF6. Ibanga phakathi kothintana nabo abahambayo nabamile lanele ukumelana nokweqile kokutakula. Uhlelo lulula futhi luthembekile, olunokugqoka okuncane kokuthintana nokuphila isikhathi eside kagesi.
● Inkomba yesimo se-switchgear:
Kufakwe ngqo ku-drive shaft, lokhu kunikeza inkomba eqinisekile yendawo yoxhumana naye. (isithasiselo A se-IEC 62271-102 ejwayelekile).
● Isileva esisebenzayo:
Lokhu kuklanywe ngedivayisi ye-anti-refl ex emisa noma yimuphi umzamo wokuphinda uvule idivayisi ngokushesha ngemva kokuvala iswishi noma isinqamuleli somhlaba.
● Idivayisi yokukhiya:
Phakathi kwengidi eyodwa nezintathu yenza okulandelayo ukuthi kukhiywe:
● ukufinyelela ku-switch shaft noma i-circuit breaker
● ukufinyelela ku-shaft yokushintsha yesinqamuleli somhlaba
● ukusebenza kwenkinobho yokuphusha yokuvula. ● Ukushintsha okulula nokulula
Izilawuli zikagesi nezikagesi zihlangene ku-fascia yangaphambili, kuphaneli
okufaka umdwebo wohlelo okhombisa isimo sedivayisi (evaliwe, evuliwe, efakwe umhlaba):
● Kuvaliwe:
i-drive shaft isetshenziswa ngendlela esebenza ngokushesha, ezimele ku-opharetha. Awekho amandla agcinwa ekushintsheni, ngaphandle kwalapho kushintshwa
imisebenzi iyenzeka.
Kuma-switch fuse ahlanganisiwe, indlela yokuvula ihlomile ngesikhathi esifanayo njengoba abathintwayo bevaliwe.
● Ukuvula:
iswishi ivulwa kusetshenziswa indlela efanayo esheshayo, esebenza ngakolunye uhlangothi.
Kuyunithi ye-fuses yokushintsha ehlanganisiwe, ukuvulwa kulawulwa yilokhu:
● inkinobho yokucindezela
● iphutha.
● Earthing:
i-specific control shaft inika amandla ukuvuleka noma ukuvala othintana nabo bomhlaba. Ukufinyelela kule shaft kuvinjwe isembozo esingashelela emuva uma iswishi ikhona
evulekile kodwa ehlala ivaliwe uma ivaliwe.
Inkomba yokuba khona kwe-voltage
Lolu cingo luhlanganise izibani zohlobo lwe-VPIS (Voltage Presence Indicating System), ngokuvumelana nezinga le-IEC 61958, olwenza ukuba khona (noma ukungabikho) kwamandla kagesi kuhlolwe ezintanjeni.
Ukungazweli endaweni ezungezile
● Indawo evalekile yangaphakathi, iqukethe izingxenye ezisebenzayo ze-LBSkit
(switch, earthing disconnector). Igcwele i-SF6 ngokuhambisana nezincazelo zezincomo ze-IEC 62271-200 “zokucindezela okuvaliwe.
amasistimu”.
Ukuvalwa kuhlolwa ngokuhlelekile efekthri.
● Izingxenye ziklanywe ukuze kutholwe ukusabalalisa kwendawo kagesi efanele.
