ISwitchgear luhlobo lwezinto ezisebenza ngogesi, ingaphandle leswishi kuqala lingena kuswishi omkhulu wokulawula kukhabethe, bese lingena kuswishi engaphansi kokulawula, futhi isekethe ngayinye isethwe ngokuya ngezidingo zayo.
Njengensimbi, ukulawula okuzenzakalelayo, switch yamagnetic motor, zonke izinhlobo zama-contactor we-AC, ezinye zisethelwe negumbi lokucindezela okuphezulu kanye nekhabethe eliphansi lokushintshela ikhabethe, elinebhasi elinengcindezi enkulu, njengezitshalo zamandla, ezinye zisethelwe ukuvikela imishini esemqoka yokunciphisa umthwalo weviki eliphansi.
Umsebenzi omkhulu wokushintshwa kwekhabhinethi ukuvula nokuvala, ukulawula nokuvikela imishini kagesi ngenkathi kwenziwa ugesi, ukuhambisa, ukusabalalisa kanye nokuguqulwa kwamandla kagesi.
Izinto ezikwikhabhinethi yokushintsha ikakhulukazi zifaka i-breaker yesekhethi, inkinobho yokunqamula, iswishi yokulayisha, indlela yokusebenza, i-inductor mutual namadivayisi ahlukahlukene wokuvikela.
Kunezindlela eziningi zokuhlukanisa i-switchgear, njengokufakwa kwesekhethi yesifunda kungahlukaniswa kube switchgear ehambayo kanye ne-switchgear engaguquki;
Noma ngokuya ngesakhiwo esehlukile sekhabethe, lingahlukaniswa libe ikhabethe lokuvula elivulekile, ikhabethe lezinsimbi elivaliwe lensimbi, kanye nensimbi evaliwe ekhishini yokushintshela;
Ngokwamazinga ahlukene we-voltage angahlukaniswa abe switchgear ephezulu yamandla, i-switchgear yamandla aphakathi ne-switchgear yamandla aphansi.
Ikakhulu isebenza ezitshalweni zikagesi, iziteshi ezingaphansi komhlaba, i-petrochemical, i-metallurgical steel rolling, indwangu elula yezimboni, amafektri namabhizinisi ezimayini nezindawo zokuhlala, izakhiwo eziphakeme nezinye izikhathi ezihlukile.
A. "Ukuvikelwa Okuhlanu" kwe-High Voltage switchgear
1. Ngemuva kokuthi inqola yesekeli le-vacuum ku-high voltage switch switch iKhabhinethi ivala endaweni yokuhlola, i-trolley circuit breaker ayikwazi ukungena endaweni yokusebenza. (Vimbela ukuvala ngomthwalo)
2. Lapho ummese wokumisa ekhabetheni lokushintsha amandla kagesi omkhulu usesimeni, ikhefu lesifunda lemoto alikwazi ukungena nokuvala.
3. Lapho i-vacuum circuit breaker ku-high voltage switch switch isebenza ngokuvalwa, umnyango ongemuva wekhabethe ukhiyiwe ngomshini emmese waphansi. (Ukuvimbela ukuduka kogesi)
I-vacuum circuit breaker ekhabhathini ephezulu yokushintsha amandla ivala ngesikhathi sokusebenza, futhi ummese wokumisa awunakufakwa. (Vimbela ikhebula lokugxila ekulengisweni lapho libukhoma)
I-vacuum circuit breaker ekhabhathini ephezulu yokushintsha amandla kagesi ayikwazi ukuphuma endaweni yokusebenza kwekhefu lesifunda lemoto uma isebenza. (Vimbela ukubopha ibhulethi ngomthwalo)
B. Ukwahlukanisa
Kuhlukaniswe ngesigaba samandla kagesi
Ngokwokwahlukaniswa kwezinga lamandla kagesi, i-AC1000V nangaphansi kuvamise ukubizwa nge-low-voltage switchgear (njenge-PGL, GGD, GCK, GBD, MNS, njll.), Ne-AC1000V nangaphezulu kubizwa ngama-high-voltage switchgear (njenge-GG- 1A, XGN15, KYN48, njll.) .Kwezinye izikhathi amandla wekhabethe levolthi ephezulu yi-AC10kV ebizwa ngekhabhathi yamandla kagesi aphakathi (njenge-XGN15 10kV ring network cabinet).
C. Kuhlukaniswa ngefomu le-wave wave
Ihlukaniswe yaba: AC switch iKhabhinethi, DC switch iKhabhinethi.
D. Kuhlukaniswa ngesakhiwo sangaphakathi
Khipha switchgear (njenge-GCS, GCK, MNS, njll.), I-switchgear engaguquki (njenge-GGD, njll.)
E. Ngokusebenzisa
Amakhabethe womugqa ongenayo, ikhabethe lomugqa ophumayo, ikhabethe lesilinganiso, ikhabethe lesinxephezelo (ikhabethe lekhabethe), ikhabethe lekhoneni, ikhabethe lebhasi.
Izinqubo zokusebenza
Inqubo yokudlulisa amandla
1. Faka ipuleti lokufaka uphawu ngemuva, bese uvala umnyango wangaphambili.
2. Sebenzisa umshini wokuphotha waphansi bese uwenza uvuleke.
3. Phusha imoto yesandla (esimweni sokuvuleka okuvulekile) ungene kwikhabhinethi (indawo yokuhlola) ngemoto yokudlulisa (ipulatifomu yemoto).
4. Faka ipulaki yesibili kusokhethi emile (inkomba yendawo yokuhlola ivuliwe), vala umnyango wangaphakathi ophakathi.
5. cindezela ikalishi lesandla lisuka endaweni yokuhlola (isimo esivulekile) liye endaweni yokusebenza nesibambo (inkomba yendawo yokusebenza ivuliwe, inkomba yendawo yokuhlola icishiwe).
6. Ukuvala imoto yesekhethi yesekethe.
Inqubo yokuhluleka kwamandla kagesi
1 Vula ikhebula leselula lephule.
Phuma emotweni ngesandla usuka lapho usebenza khona (vula isimo sebhuleki) uye endaweni yokuhlola ngesibambo.
3 (isibonisi sesimo sokusebenza sicishiwe, isibonisi sesimo sokuhlola sivuliwe).
4 Vula umnyango wangaphakathi ophakathi.
5 Donsela ipulaki yesibili esikhwameni esimile (isibonisi sesimo sokuhlola sicishiwe).
6. Phuma emotweni yesandla (endaweni evulekile) ngaphandle kwekhabethe ngemoto yokudlulisa.
7. Sebenzisa umshini wokuphotha womhlabathi uwenze usondele.
8. Vula ipuleti lokuvala emuva nomnyango ongaphansi ongaphambili.
Ukuqapha nokuphepha
Ngochungechunge lwezivivinyo zokuzwa kwemithombo ehlukahlukene yokukhanya, izici ze-arc arc arc arc yangaphakathi ziyanqunywa.
Ngalesi sizathu, inzwa ye-fiber fiber kanye nedivayisi eyongayo nesebenzayo esabalalayo yamaphoyinti amaningi ukuthola nokuvikela idivaysi yenziwa ngokusebenzisa umbandela owodwa we-arc.
Idivayisi inezinzuzo zesakhiwo esilula, izindleko eziphansi, isikhathi esisheshayo sokusebenza kanye nekhono elinamandla lokulwa nokuphazamiseka.
Hhayi kuphela ukuthi ingasetshenziswa yodwa, kepha futhi ingahlanganiswa namadivayisi wokuvikela edluliselwe ahlukahlukene, ukuze izindleko zekhabinethi yokushintsha inganyuswa, izinga lobuchwepheshe kanye nenani elengeziwe lithuthukiswa kakhulu.
