Isixhobo sokutshintshela iVolthi ephezulu ye-6KV

Isikhululo samandla, njengendawo apho umbane uveliswa khona, sidla ngokuba nombane. Kwifektri yethu, injini ekwifektri yahlulwe kakhulu yaba yi-6KV motor kunye ne-400V motor. I-6KV switchgear sisixhobo sombane esiyimfuneko.

Iswitshi yombane ophezulu isetyenziswa kakhulu kwinkqubo yokusasaza amandla ukuze ifumane kwaye isasaze amandla ombane.
Ayinakufaka nje kuphela inxalenye yezixhobo zombane okanye umgca ngaphakathi okanye ngaphandle kokusebenza ngokweemfuno zokusebenza kwegridi yombane, kodwa ikwanokususa ngokukhawuleza inxalenye enesiphene kwigridi yombane xa izixhobo zombane okanye umgca unesiphako, ukuqinisekisa ukusebenza okuqhelekileyo kwenxalenye engenasiphako yegridi yombane, kunye nokhuseleko lwezixhobo kunye nabasebenzi bokusebenza nokulungisa.
Ngoko ke, iswitshi ye-voltage ephezulu sisixhobo sokusasaza esibaluleke kakhulu, ukusebenza kwayo okukhuselekileyo nokuthembekileyo kwenkqubo yamandla kubaluleke kakhulu.

1. Uhlu lwezixhobo zokutshintsha umbane eziphezulu
Ngokwendlela yohlobo lwesakhiwo:
Uhlobo oluxhotyisiweyo: igumbi ngalinye eline-metal plate yokwahlulwa kunye ne-grounding;
(2) Uhlobo lwesithuba: igumbi ngalinye lahlulwe yipleyiti yesinyithi enye okanye ezingaphezulu;
(3) uhlobo lwebhokisi: eneqokobhe lesinyithi, kodwa isithuba singaphantsi kwezimbini zokuqala;
Ngokwendlela ebekwe ngayo i-circuit breaker:
(1) Uhlobo lomgangatho: i-circuit breaker, i-hand car ngokwayo efikayo, ityhalelwe kwikhabhathi;
(2) uhlobo oluphakathi: ilori yesandla efakwe embindini wekhabhathi yeswitshi:

3. Utshintsho lwe-voltage ephezulu

Ngokwendlela yokucima i-arc, i-circuit breaker inokwahlulwa ibe:
① Isixhobo sokuqhekeza ioyile.
Yahlulwe yaba yi-multi-oil circuit breaker kunye ne-oil circuit breaker encinci.
Zizinto ezidityanisiweyo kwioyile ukuze ziqhekeke, zivulwe, ngeoyile yetransformer njengesixhobo sokudibanisa.
② Isixhobo sokwaphula isekethe yomoya esicinezelweyo.
Isixhobo sokwaphula iisekethe esisebenzisa umoya ocinezelweyo xa kucinezelwe kakhulu ukuvuthuza i-arc.
③SF6 iqhekeza lesekethe.
Isixhobo sokwaphula iisekethe esisebenzisa igesi ye-SF6 ukuvuthuza i-arc.
④Isixhobo sokwaphula isekethe yomoya.
I-circuit breaker enxibelelana nayo yaphukile kwaye iqhagamshelwe kwi-vacuum kwaye i-arc yayo icinyiwe kwi-vacuum.
⑤ Isixhobo sokwaphula isekethe yokuvelisa igesi eqinileyo.
Isixhobo sokwaphula isekethe esisebenzisa izinto ezivelisa igesi eqinileyo ukucima igesi ebolileyo phantsi kwesenzo sobushushu obuphezulu be-arc.
⑥ Isixhobo sokwaphula isekethe esibizwa ngokuba yiMagnetic blow circuit breaker.
Isixhobo sokwaphula isekethe apho i-arc ivuthelwa kwi-arc grid yi-magnetic field emoyeni ukuze inwebe kwaye ipholise i-arc.
Umzi-mveliso wethu usebenzisa indlela yokucima i-vacuum arc.

4. Izikhundla ezintathu zeswitshi ye-voltage ephezulu
Indawo yokusebenza: i-circuit breaker iqhagamshelwe kwisixhobo esiphambili. Emva kokuvala, umbane udluliselwa ukusuka kwibhasi ukuya kumgca wothumelo nge-circuit breaker.
Indawo yovavanyo: Iplagi yesibini ingafakwa kwisokethi ukuze kufunyanwe umbane.
I-circuit breaker ingavalwa, ivuliwe, i-indicator light ehambelanayo;
I-circuit breaker ayinanxibelelwano nezixhobo eziphambili kwaye inokwenza imisebenzi eyahlukeneyo, kodwa ayiyi kuba nafuthe kwicala lomthwalo, ngoko ke ibizwa ngokuba yindawo yovavanyo.
Indawo yokulungisa: akukho nxibelelwano phakathi kwe-circuit breaker kunye nesixhobo esiphambili (ibhasi), amandla okusebenza alahlekile (iplagi yesibini ikhutshiwe), i-circuit breaker ikwindawo yokuvula, kwaye imela yomhlaba ikwimeko yokuvala.

5. Ukuthintela ukutshixa okuhlanu kwikhabhinethi yokutshintsha
1, i-circuit breaker kunye ne-grounding switch zikwindawo yokuvula, inqwelo yesandla isuka kwindawo yokwahlulwa/yovavanyo ukuya kwindawo yokusebenza;
2, i-circuit breaker kwindawo yokuvula yesandla ukuze isuke kwindawo yokusebenza iye kwindawo yovavanyo/yokwahlukanisa;
3, xa uvavanyo okanye indawo yokusebenza ingena, i-circuit breaker ingavalwa;
4, isandla kwindawo yovavanyo okanye yokusebenza ngaphandle kombane wolawulo, i-circuit breaker ayinakuvala, ivula ngesandla kuphela;
5. Xa imoto yesandla ikwindawo yokusebenza, iplagi yesibini itshixiwe kwaye ayinakutsalwa;
6, faka isandla kwindawo yokuvavanya/yokwahlukanisa okanye ushukumise, iswitshi yomhlaba ukuze ivalwe;
7. Emva kokuba iswitshi yokumisa umhlaba ivaliwe, ucango lungavulwa;
