Uhlolojikelele

• I-FZN61-12DG/630-20 kanye ne-FZN61-12DG/1250-25 yangaphakathi ye-AC high voltage miniaturized vacuum load break switch iyimishini yokushintsha amandla kagesi ezigaba ezintathu eziphezulu ezinama-voltage akalwe angu-12kV kanye nemvamisa elinganiselwe engu-50Hz, isetshenziselwa ukushintsha amaza okulayisha. , i-loop yamanje evaliwe, i-transformer engalayishi kanye yamanje yokushaja ikhebula, futhi yenza isifunda esifushane samanje. Iswishi yekhefu le-vacuum enezimo ezintathu ezincane efakwe iswishi yokunqamula phezulu kanye neswishi yomhlaba ezansi ingamelana namandla wesekethe emfishane.

• FZRN61-12DG/200-31.5 AC high voltage miniaturized vacuum load break switch-fuse inhlanganisela yeyunithi iyimishini yasendlini yokushintsha amandla kagesi aphezulu, ihlanganisa i-FZRN61-12DG i-miniaturized load break switch kanye ne-S □LAJ-12 (XRNT □-10) yamandla kagesi aphezulu i-fuse enomkhawulo wamanje. Ingakwazi ukwephula noma iyiphi i-current kuze kufike ku-short-circuit current; i-switch break break iphula i-current esebenzayo, i-fuse iphula i-current, futhi ijoyinti liphula noma imuphi umsinga phakathi kwamandla asebenzayo kanye ne-short-circuit current ephelele. Ngesikhathi esifanayo, i-fuse ivula inkinobho yekhefu lomthwalo ngokusebenzisa isiteleka sayo.

Isingeniso Sesakhiwo Somkhiqizo

• I-vacuum yokunqamula iswishi yekhefu ingumkhiqizo ojwayelekile; isakhiwo sohlaka: isakhiwo esihlangene, iswishi yokunqamula edidiyelwe, iswishi yekhefu le-vacuum load, i-fuse, iswishi yomhlaba iyonke imikhiqizo kagesi enamandla kakhulu esebenza kakhulu.

• Usayizi omncane: ububanzi esimweni esivulekile nesivaliwe: ububanzi be-vacuum load break switch ≤299mm.

• Amapharamitha aphezulu: umthamo olinganiselwe we-vacuum load break switch ufike ku-1250A; umthamo wamanje olinganiselwe weyunithi yenhlanganisela ye-switch-fuse ifinyelela ku-200A, engavikela i-transformer engu-2000kVA.

• Iswishi yokunqamula ulayini ongenayo ixhunywe neswishi yomhlaba. Ngemva kokuvulwa kweswishi yomhlaba, inkinobho yokunqamula umugqa ongenayo izovalwa ngesenzo esifanayo.

• Iswishi yokunqamula ejikelezayo enokwephuka okubonakalayo ngemva kokuvula.

• Kukhona ukuxhuma komshini phakathi kweswishi yokunqamula ukulayisha kwe-vacuum kanye neswishi yokunqamula (umhlaba) ukuvimbela ukusebenzisa kabi. Qinisekisa ukuthi iswishi yekhefu le-vacuum ingavalwa ngemva kokuba iswishi yokunqamula ivaliwe; iswishi yokunqamula ingavulwa kuphela ngemva kokuvulwa kweswishi yekhefu lokulayisha kwe-vacuum.

• I-switch break break ingafakelwa umshini wokusebenza kagesi, ongugesi kanye nesandla, ingakwazi ukubona isilawuli kude.

• I-switch eyisiza yokuzikhethela, i-shunt kanye nokukhululwa kwe-overcurrent.

• Ijubane lokuvula nokuvala le-vacuum load break switch alithintwa ukusebenza okwenziwa ngesandla.

• Indlela yokulwa nokungasebenzi kahle ihlangabezana nezidingo “zezivimbelo ezinhlanu” zesethi ephelele yemishini yamandla kagesi aphezulu.
