6KV High Voltage Switchgiya

Malo opangira magetsi, monga malo opangira magetsi, nthawi zambiri amayenera kugwira ntchito ndi magetsi. Pa fakitale yathu, mota yomwe ili mufakitaleyi imagawidwa kwambiri m'magalimoto a 6KV ndi mota ya 400V. 6KV switchgear ndi zida zamagetsi zofunika kwambiri.

Chosinthira magetsi champhamvu chimagwiritsidwa ntchito kwambiri mu dongosolo logawa mphamvu kuti chilandire ndikugawa mphamvu zamagetsi.
Sizingangoyika gawo la zida zamagetsi kapena chingwe mkati kapena kunja kwa ntchito malinga ndi zosowa za gridi yamagetsi, komanso zimatha kuchotsa mwachangu gawo lolakwika kuchokera pa gridi yamagetsi pamene zida zamagetsi kapena chingwecho chili ndi vuto, kuti zitsimikizire kuti gawo lopanda vuto la gridi yamagetsi likugwira ntchito bwino, komanso chitetezo cha zida ndi ogwira ntchito ndi okonza.
Chifukwa chake, switchgear yamagetsi okwera kwambiri ndi chida chofunikira kwambiri chogawa, magwiridwe ake otetezeka komanso odalirika a dongosolo lamagetsi ali ndi tanthauzo lofunika kwambiri.

1. Gulu la switchgear yamagetsi okwera kwambiri
Malinga ndi mtundu wa kapangidwe kake:
Mtundu wa zida: chipinda chilichonse chokhala ndi mbale yachitsulo yodzipatula komanso yokhazikika;
(2) Mtundu wa nthawi: chipinda chilichonse chimalekanitsidwa ndi mbale imodzi kapena zingapo zachitsulo;
(3) mtundu wa bokosi: ndi chipolopolo chachitsulo, koma nthawi yolumikizira ndi yochepa kuposa ziwiri zoyambirira;
Malinga ndi malo a chosokoneza ma circuit:
(1) Mtundu wa pansi: chodulira magetsi, galimoto yoyendetsedwa yokha ikutera, ikukankhidwira mu kabati;
(2) mtundu wapakati: galimoto yoyendetsedwa ndi manja yoyikidwa pakati pa kabati yosinthira:

2. Kapangidwe ka mphamvu yamagetsi yapamwambazida zosinthira

A: Chipinda cha basi

B: (Chipinda chosinthira maginito) chipinda chogwiritsira ntchito manja

С: Chipinda cha chingwe

D: Chipinda cholumikizira zida zotumizirana

1. Chipangizo chothandizira kupanikizika

2. Chipolopolo

3. Basi ya nthambi

4. Chikwama cha basi

5. Mzere wa ambuye

6. Chipangizo cholumikizira chosasunthika

7. Bokosi lolumikizirana

8. Transformer yamagetsi

9. Chosinthira Chokhazikika

10. Chingwe

11. Wogwira

12. Basi yapansi

13. Cholekanitsa kukweza ndi kutsitsa

14. Kugawa (valavu)

15. Pulagi yachiwiri

16. Galimoto yoyendetsa mawondo yozungulira dera

17. Tenthetsani chotsukira chinyezi

18. Kugawa kochotsedwa

19. Njira yogwiritsira ntchito switch yotsika pansi

20. Lamulirani waya wocheperako

21. Mbale yoyambira

3. Chosinthira chamagetsi champhamvu

Malinga ndi chipangizo chozimitsira arc, chosokoneza ma circuit chingagawidwe m'magulu awiri:
① Chotsekera maginito a mafuta.
Imagawidwa m'magulu awiri: multi-oil circuit breaker ndi ochepa.
Ndi zolumikizirana mu mafuta kuti zisweke, ndi mafuta osinthira ngati cholumikizira.
② Chotsekera mpweya chopanikizika.
Chotsekera mawaya chomwe chimagwiritsa ntchito mpweya wopanikizika pamphamvu kwambiri kuti chiphulitse arc.
③SF6 choswa dera.
Chotsekera mawaya chomwe chimagwiritsa ntchito mpweya wa SF6 kuti chiphulitse arc.
④Chotsukira dera chopanda mpweya.
Chotsekera dera chomwe kulumikizana kwake kwasweka ndi kulumikizidwa mu vacuum ndipo arc yake imazimitsidwa mu vacuum.
⑤ Chotsekera magetsi chopangira mpweya wolimba.
Chotsekera dera chomwe chimagwiritsa ntchito zinthu zopangira mpweya wolimba kuzimitsa mpweya womwe wawonongeka chifukwa cha kutentha kwakukulu kwa arc.
⑥ Chothyola maginito chophulitsira magetsi.
Chotsekera dera chomwe arc imawombedwa mu arc grid ndi mphamvu yamaginito mumlengalenga kuti italikitse ndikuziziritsa arc.
Fakitale yathu imagwiritsa ntchito njira yozimitsira mpweya pogwiritsa ntchito vacuum arc.

4. Malo atatu a chosinthira chamagetsi chapamwamba
Malo ogwirira ntchito: chodulira magetsi chimalumikizidwa ndi zida zoyambira. Pambuyo potseka, mphamvu imatumizidwa kuchokera ku basi kupita ku chingwe chotumizira magetsi kudzera mu chodulira magetsi.
Malo oyesera: Pulagi yachiwiri ikhoza kuyikidwa mu soketi kuti ipeze magetsi.
Chotsekera dera chikhoza kutsekedwa, kutsegulidwa, kuwala koyenera kowonetsa;
Chotsekera mawaya sichilumikizana ndi zida zoyambira ndipo chingathe kuchita ntchito zosiyanasiyana, koma sichidzakhudza mbali ya katundu, kotero chimatchedwa malo oyesera.
Malo okonzera: palibe kukhudzana pakati pa chodulira cha dera ndi chipangizo chachikulu (basi), mphamvu yogwiritsira ntchito yatayika (pulagi yachiwiri yatulutsidwa), chodulira cha dera chili pamalo otsegulira, ndipo mpeni wogwetsa pansi uli pamalo otsekera.

5. Kuletsa kabati yosinthira maloko asanu
1, chosinthira magetsi ndi chosinthira pansi zili pamalo otsegulira, ngolo yonyamula katundu ili kutali ndi malo odzipatula/oyesera kuti isamukire kumalo ogwirira ntchito;
2, choswa dera pamalo otseguka a dzanja kuti chisunthe kuchokera pamalo ogwirira ntchito kupita pamalo oyesera/odzipatula;
3, ngati choyesera kapena malo ogwirira ntchito agwiritsidwa ntchito, chotsegula dera chikhoza kutsekedwa;
4, pogwiritsa ntchito kuyesera kapena malo ogwirira ntchito popanda magetsi owongolera, chotsegula dera sichingathe kutseka, koma kutsegula pamanja kokha;
5. Galimoto yogwira ntchito ikagwira ntchito, pulagi yachiwiri imatsekedwa ndipo singathe kukokedwa;
6, perekani malo oyesera/kudzipatula kapena kusuntha, chosinthira pansi kuti chitseke;
7. Pambuyo poti chosinthira cha pansi chatsekedwa, chitseko chikhoza kutsegulidwa;
