I-Switchgear ye-6KV High Voltage

Isitshalo sikagesi, njengendawo lapho kukhiqizwa khona ugesi, sivame ukubhekana nogesi. Embonini yethu, injini efektri ihlukaniswe kakhulu ngenjini engu-6KV kanye nenjini engu-400V. I-switchgear engu-6KV iyimishini kagesi ebaluleke kakhulu.

I-switchgear enamandla aphezulu isetshenziswa kabanzi ohlelweni lokusabalalisa amandla ukwamukela nokusabalalisa amandla kagesi.
Ayikwazi nje ukufaka ingxenye yemishini kagesi noma umugqa ngaphakathi noma ngaphandle kokusebenza ngokwezidingo zokusebenza kwegridi yamandla, kodwa futhi ingasusa ngokushesha ingxenye enephutha kugridi yamandla lapho imishini kagesi noma umugqa unephutha, ukuze kuqinisekiswe ukusebenza okuvamile kwengxenye engenaphutha yegridi yamandla, kanye nokuphepha kwemishini kanye nabasebenzi bokusebenza nokulungisa.
Ngakho-ke, i-switchgear enamandla aphezulu iyimishini yokusabalalisa ebaluleke kakhulu, ukusebenza kwayo okuphephile nokuthembekile kohlelo lwamandla kunokubaluleka okubaluleke kakhulu.

1. Ukuhlukaniswa kwe-switchgear enamandla aphezulu
Ngokusho kohlobo lwesakhiwo:
Uhlobo oluhlomile: igumbi ngalinye elinophahla lwensimbi kanye nophahla oluqinile;
(2) Uhlobo lwezikhawu: igumbi ngalinye lihlukaniswe yipuleti elilodwa noma ngaphezulu lensimbi;
(3) uhlobo lwebhokisi: olunegobolondo lensimbi, kodwa isikhawu singaphansi kwezimbili zokuqala;
Ngokusho kokubekwa kwe-circuit breaker:
(1) Uhlobo lwephansi: i-circuit breaker, imoto yesandla ngokwayo efika, icindezelwe ekhabetheni;
(2) uhlobo oluphakathi: iloli lesandla elifakwe phakathi kwekhabhinethi yokushintsha:

2. Ukwakheka kwamandla kagesi aphezuluigiya lokushintsha

A: Igumbi lebhasi

2. Igobolondo

3. Ibhasi legatsha

4. Ibhokisi lebhasi

5. Umugqa weNkosikazi

6. Idivayisi yokuxhumana engaguquki

7. Ibhokisi lokuxhumana

8. I-transformer yamanje

9. Ukushintsha Okuyisisekelo

10. Ikhebula

11. Umboshwa

12. Ibhasi elihamba phansi

13. Isihlukanisi sokulayisha nokulayisha

14. Ukuhlukanisa (i-valve)

15. Ipulaki yesibili

16. Iloli yesandla ye-circuit breaker

17. Shisisa umshini wokususa umswakama

18. Ukwahlukanisa okungakhishwa

19. Indlela yokusebenza yokushintsha phansi

20. Lawula isikhala sentambo encane

21. Ipuleti lesisekelo

3. Iswishi ye-voltage ephezulu

Ngokusho kwe-arc extinguishing medium, i-circuit breaker ingahlukaniswa kanje:
① I-oyela circuit breaker.
Ihlukaniswe yaba yi-multi-oil circuit breaker kanye ne-oil circuit breaker encane.
Ziyizinto ezithintana emafutheni ukuze ziphuke, zivulwe, ngowoyela we-transformer njengendlela yokuxhuma.
② I-compressed air circuit breaker.
I-circuit breaker esebenzisa umoya ocindezelwe ngomfutho ophezulu ukuze ikhiphe i-arc.
③SF6 i-circuit breaker.
I-circuit breaker esebenzisa igesi ye-SF6 ukuqhuma i-arc.
④I-vacuum circuit breaker.
I-circuit breaker exhumanisayo iphukile futhi ixhunywe ku-vacuum futhi i-arc yayo icime ku-vacuum.
⑤ I-circuit breaker yokukhiqizwa kwegesi eqinile.
I-circuit breaker esebenzisa izinto ezikhiqiza igesi eqinile ukucima igesi ebolile ngaphansi kwesenzo sokushisa okuphezulu kwe-arc.
⑥ I-magnetic blow circuit breaker.
I-circuit breaker lapho i-arc ishaywa khona ibe yi-arc grid yi-magnetic field emoyeni ukuze inwebe futhi ipholise i-arc.
Ifektri yethu isebenzisa indlela yokucima i-vacuum arc.

4. Izikhundla ezintathu zeswishi ye-voltage ephezulu
Indawo yokusebenza: i-circuit breaker ixhunywe nemishini eyinhloko. Ngemva kokuvala, amandla adluliselwa kusuka ebhasini aye emgqeni wokudlulisela nge-circuit breaker.
Indawo yokuhlola: Ipulaki yesibili ingafakwa kusokhethi ukuze kutholakale ugesi.
I-circuit breaker ingavalwa, ivuleke, inkomba ehambisanayo ikhanye;
I-circuit breaker ayinakho ukuxhumana nemishini eyinhloko futhi ingenza imisebenzi ehlukahlukene, kodwa ngeke ibe nomthelela ohlangothini lomthwalo, ngakho-ke ibizwa ngokuthi indawo yokuhlola.
Indawo yokulungisa: akukho ukuxhumana phakathi kwe-circuit breaker kanye nemishini eyinhloko (ibhasi), amandla okusebenza alahlekile (ipulagi yesibili ikhishwe), i-circuit breaker isendaweni yokuvula, kanti ummese womhlabathi usesimweni sokuvala.

5. Ukuvimbela ukukhiya okuhlanu kwekhabhinethi yokushintsha
1, i-circuit breaker kanye ne-grounding switch zisendaweni yokuvula, inqola yesandla isuka endaweni yokuhlukaniswa/yokuhlola ukuze iye endaweni yokusebenza;
2, i-circuit breaker endaweni yokuvula yesandla ukuze isuke endaweni yokusebenza iye endaweni yokuhlola/yokuhlukanisa;
3, uma kufakwe endaweni yokuhlola noma yokusebenza, i-circuit breaker ingavalwa;
4, isandla esivivinyweni noma endaweni yokusebenza ngaphandle kwe-voltage yokulawula, i-circuit breaker ayikwazi ukuvala, ukuvulwa ngesandla kuphela;
5. Uma imoto yesandla isesimweni sokusebenza, ipulaki yesibili ikhiyiwe futhi ayikwazi ukukhishwa;
6, faka esikhundleni sokuhlola/sokuhlukaniswa noma uhambise, inkinobho yomhlabathi ukuze ivalwe;
7. Ngemva kokuba iswishi yokumisa ivaliwe, umnyango ungavulwa;
