GPR-24(12)kV Series Ring Main Unit Switchgear
Isifinyezo
I-GPR-24 series Ring Main Unit iyisishintshi esinwebekayo se-SF6, esinogesi olinganiselwe ongu-12&24 kV.Zonke izingxenye zayo ezibukhoma ze-HV ziqukethwe ethangini legesi elingangeni emoyeni, elenziwe ngensimbi engagqwali engu-3mm.Yonke inhlangano yokushintsha ifakwe i-SF6, futhi ayinawo noma yiliphi ithonya langaphandle, iqinisekisa ukuthi ithembekile enkulu yesevisi nokugcinwa mahhala.Ngohlobo lwe-plug-in yesandiso sebha yebhasi, uchungechunge lwe-GPR-24 Ring Main Unit ingaba yenhlanganisela yamahhala kanye ne-modularization egcwele.Isandiso sebha yebhasi siphumelele ukuhlolwa kohlobo lwamandla nokuzinza kwe-thermal, futhi sivalwe ngokuphelele futhi sivikelekile, sibonisa ukwethembeka nokuphepha okuphezulu.Iyunithi ye-GPR-24 Ring Main ilungele yonke inethiwekhi ye-MV kuze kufike ku-24 kV, zonke iziteshi zikagesi ezihlangene, iziteshi ezincane zokusabalalisa amandla kuzo zonke izimboni ezibalulekile, njengemboni yamakhemikhali kaphethiloli, izimboni zensimbi nezezimayini, nazo zonke iziteshi ezishintshashintshayo namandla omoya. uhlelo.
Izici
1. Indlela yenqubo ethuthukisiwe yethangi likaphethiloli
Isistimu yokusika nokubhoboza ye-laser elawulwa idijithali kanye nesistimu yokushisela i-laser enezinhlangothi ezintathu nezinhlaka ezinhlanu ezithunyelwa zisuka eJalimane ziqinisekisa ukucinana kwegesi nokufana kwawo wonke amathangi egesi.
Isistimu yokutholwa kokuvuza kwe-helium ezenzakalelayo ngokuphelele nebalulekile, eyenziwe yi-SEILER Vakuumtechnik GmbH, ngokuthola ukuvuza kwe-Helium nge-mass spectrograph, lehlisa izinga lokuvuza kwegesi ngonyaka lifinyelele ngaphansi kuka-0.02%, liqinisekisa ubude besikhathi sethangi likaphethiloli iminyaka engaphezu kwengu-30.
Indlela yenqubo ethuthukisiwe yezingxenye.
Zonke izingxenye ezivalekile ze-epoxy resin, okuhlanganisa nezigxobo ezivalekile, zenziwa ngokuzenzakalelayo futhi okulawulwa ngedijithali i-epoxy resin vacuum vacuum mixing/pressure gelatinizing system evela e-Hedrich (Germany) .
Isixhumi sebha yebhasi, isixhumi sekhebula, ipulaki yokugcina nezinye izingxenye ezigqunywe ngerabha ye-silicone kukhiqizwa ngokuzenzakalelayo futhi okulawulwa ngedijithali isistimu ye-silicone yerabha exutshwa/nokucindezela kwe-gelatinizing kusuka ku-VOGEL(Switzerland).
2. Izixazululo ezinhle kakhulu zemikhiqizo
Ngesakhiwo esincane nesihlangene, amayunithi ayisisekelo asebenzayo K, T, V, B kanye no-C anobukhulu obufanayo: 350*800*1380 mm (ububanzi*ukujula*ubude) .
Qedela izixazululo:
Inguqulo eyodwa: iyunithi yokushintsha ikhefu lokulayisha, iyunithi ye-switch-fuse, iyunithi ye-vacuum circuit breaker, iyunithi yesigatshana sebha yebhasi, iyunithi yekhebula, iyunithi yokulinganisa, njll.
Inguqulo yebhulokhi ingenziwa ngamayunithi amabili, amathathu, amane, amahlanu noma ayisithupha.
Amayunithi angawodwa kanye nenguqulo yebhulokhi ingaxhunywa ngezixhumi zebha yebhasi kalula.
3. Ukuzivumelanisa nezimo okuqinile endaweni ezungezile
I-primary conductive system ivalwe ngokugcwele ethangini legesi le-SF6 futhi ngeke ithonywe imvelo yangaphandle, ngaphandle komthelela wamazolo, uthuli, inkungu kasawoti, njll. Ngakho-ke, uchungechunge lwe-GPR-24 lungasetshenziswa ezimweni ezihlukahlukene zesevisi ezinzima. .
