I-Gas Insulated Switchgear GRM6-24

GRM6-24 series SF6 gas insulated metal evalelwe switchgear (emva koku kubhekiselwa kuyo njengeigesi insulated switchgear ) ifanelekile kwisigaba sesithathu se-AC 50Hz, i-voltage elinganisiweyo ye-24kV inkqubo yokusabalalisa amandla, ukuphula kunye nokuvala umthwalo wangoku, ukulayisha ngokugqithisileyo, ukuvala kunye nokuvala isiphaluka esifutshane. Ukuqhawula imithwalo ye-capacitive efana ne-no-load transformers, imigca ephezulu, imigca yentambo kunye neebhanki ze-capacitor kumgama othile, kwaye udlale indima yokusabalalisa amandla, ukulawula kunye nokukhuselwa kwinkqubo yamandla. I-GRM6-24 ithatha isakhiwo esivaliweyo ngokupheleleyo, zonke izidumbu eziphambili ezihlawuliswayo zitywinwe kwigumbi lomoya elidityaniswe ngamacwecwe ensimbi engenasici, kwaye izinga lokukhusela lifikelela kwi-IP67. I-multi-circuit ring network switchgear esebenza ngokukhuselekileyo kunye nokuthembeka okuphezulu okukwazi ukulungelelanisa kwiimeko ezahlukeneyo zokusingqongileyo ezifana nenkungu emanzi kunye netyuwa, njengezikhukhula kunye nokungcola okukhulu. Isetyenziswa kakhulu kwiipaki zoshishino, izitalato, izikhululo zeenqwelo moya, iindawo zokuhlala, amaziko orhwebo aphithizelayo, njl. Ikwasetyenziswa apha: izitishi zohlobo lwebhokisi ezidityanisiweyo, iibhokisi zesebe lentambo, izixhobo zokutshintsha, izikhululo zamandla omoya, umzila ongaphantsi komhlaba kunye nezibane zetonela.

Sebenzisa imeko

• Ubushushu be-Ambient: -40℃~+40℃ (ngaphantsi -30℃ kufuneka kuthethathethwane nabasebenzisi kunye nomenzi);

• Ukuphakama:

• Ukuqina kwenyikima: akukho ngaphezu kwe-8 degrees;

• Umyinge obona buninzi bokufuma obunxulumeneyo: 24h umyinge

• Iindawo ezingenamlilo, ugqabhuko-dubulo, ukudleka kweekhemikhali kunye nokungcangcazela rhoqo okunobundlobongela.

Uphawu lolwakhiwo

• Uyilo olufakwe ngokupheleleyo kunye ne-insulated ngokupheleleyo: Zonke iindawo eziphilayo ze-GRM6-24 zitywinwe kwibhokisi edibeneyo nge-304 yensimbi engenasici, ibhokisi igcwele igesi ye-SF6 kunye noxinzelelo olusebenzayo lwe-1.4bar, kunye nenqanaba lokukhusela yi-IP67. Kufanelekile ukufakwa kwiindawo ezinomswakama ophezulu kunye nongcoliseko lothuli, ngokukodwa ezifanelekileyo kwimigodi, izikhululo zohlobo lwebhokisi kunye naziphi na iindawo ezixhomekeke kwi-flashover yomhlaba ngenxa yongcoliseko lomoya. Imveliso ifakwe kunye ne-DIN47636 ye-sleeve eqhelekileyo, kwaye ixhunywe kwikhebula ngokusebenzisa i-insulated ngokupheleleyo, itywinwe ngokupheleleyo, idibeneyo yekhebula ekhuselekileyo.

• Ukuthembeka okuphezulu kunye nokhuseleko lomntu: zonke iindawo eziphilayo zitywinwe kwigumbi lomoya le-SF6; igumbi lomoya linomjelo wokunciphisa uxinzelelo oluthembekileyo, oluye lwadlula uvavanyo lwe-arc ye-arc ye-20kA / 0.5s yangaphakathi: ukutshintshwa komthwalo kunye nokutshintsha komhlaba kukutshintsha kweendawo ezintathu, okwenza kube lula ukudibanisa phakathi kwabo. Kukho i-interlock ethembekileyo yomatshini phakathi kwekhava yecandelo lekhebula kunye nokutshintsha komthwalo, okunokuthi kuthintele ngokufanelekileyo ukungena kwixesha eliphilayo ngempazamo.

• Umjikelo wasimahla kunye nobomi obude Imveliso iyilwe ngomjikelo wobomi weminyaka engama-30. Ngethuba lomjikelezo wobomi bemveliso, utshintshi oluphambili alufuni ukugcinwa. Umlinganiselo wokuvuza wonyaka wemveliso ngu

• Ulwakhiwo olubambeneyo: Ngaphandle kwekhabhinethi yokulinganisa i-air-insulated metering kunye ne-PT, zonke iimodyuli zi-350mm ububanzi kuphela, kwaye i-cable connection bushings yazo zonke iiyunithi zinobude obufanayo emhlabeni, obulungele ukwakhiwa kwendawo.

• I-GRM6-24 inokulungiswa kunye nezixhobo zokulawula ezihlakaniphile (ukhetho), ukunika ukhuseleko olusebenzayo, ulawulo olukude kunye neenkqubo zokubeka iliso, kunye nokuxhasa ukuzenzekelayo kweenkqubo zokuhambisa amandla.

• I-GRM6-24 ibonelela ngeendlela ezimbini zokukhusela i-transformers: ukudibanisa komthwalo we-fuse kunye ne-breaker circuit kunye nokukhusela i-relay. Ukulayisha izixhobo zokudibanisa i-fuse zisetyenziselwa i-transformers ye-1600kVA nangaphantsi, ngelixa ii-circuit breakers ezine-relays zingasetyenziselwa ukukhusela i-transformer yezakhono ezahlukeneyo.

• Ukhuseleko lokusingqongileyo: Uphuhliso lwe-GRM6-24 alubandakanyi imveliso ngokwayo kuphela, kodwa kunye nokukhuselwa kokusingqongileyo ukusuka kwinkqubo yokuvelisa ukuya ekusebenzeni kwexesha lokuphila kokutshintsha. Zonke izinto ezikhethiweyo zikhethwa ukuba zibe nobungane bendalo, kwaye inkqubo yokucoca i-zero-leakage yamkelwe. Imveliso itywinwe ubomi bonke, kwaye i-90% ukuya kwi-95% yezinto eziphathekayo zinokuphinda zisetyenziswe emva kokuphela komjikelezo wobomi bemveliso.

IiParameters eziphambili zobuGcisa

Phawula:

1 ) Kuxhomekeke kumbane olinganisiweyo wefuse;

2) Unyinwe yi fuse yombane ophezulu.
