I-ZW7-40.5 yangaphandle yeVoltage ePhakamileyo yeVacuum yeSekethe iSiqhekeza

Isishwankathelo

I-ZW7-40.5 i-voltage yangaphandle yentengiso ye-AC i-vacuum ye-circuit breaker ineenzuzo zokusebenza okukhuselekileyo nokuthembekileyo, ukugcinwa lula kunye nomjikelo wokulondoloza ixesha elide.Ngenxa yokusetyenziswa kokuzaliswa kwezinto ezintsha zokukhusela, isakhiwo esipheleleyo se-transformer engagxiliyo ngaphandle kwegumbi lokucima i-arc kunye nodonga lwangaphakathi lomkhono we-porcelain lufakwe kwibhokisi ye-mechanism, ekulungele ukufakela.Ikwanqanda i-oyile, ukuvuza kwerhasi kunye neengxaki zetyhefu zezinye iiswitshi.Ngenxa yokuba abafowunelwa abaguquguqukayo kunye ne-static be-breaker circuit batywinwe kwigumbi lokucima i-arc ye-vacuum, kwaye i-vacuum isetyenziswe njenge-insulating medium kunye ne-arc yokucima i-medium, inoluhlu lweenzuzo ukuba ezinye iintlobo zokutshintsha azikwazi ukuhambelana.Ke le mveliso iyimveliso efanelekileyo yokuthatha indawo ye-DW ye-oyile ye-breaker circuit breaker.Ubume bebhokisi yendlela yokusebenza yale mveliso phakathi kwesiphambano sesiphaluka yindawo ephakathi kwe-high-voltage vacuum circuit breaker.Olu hlobo lwe-circuit breaker luyi-260mm lufutshane kunomqhekezi wesiphaluka sokuqala, kwaye lufanelekile ukufakwa kwiindawo ezinendawo encinci.
Le mveliso ifanelekile kwi-40.5kV, i-50.Hz inkqubo yokusabalalisa amandla esigaba sesithathu, njengomthwalo wangoku, ukulayisha ngokugqithisileyo kunye ne-short-circuit current ye-sub kunye nesikhululo.

Umsebenzi ongundoqo

◆ Ukusebenzisa ukucima i-arc yevacuum.Ukophuka okunamandla, ubomi obude bombane, kunye nobomi bomatshini amaxesha angama-10,000:
◆ Ulwakhiwo olulula, olungagciniyo, ixesha elide lokungabikho kogcino;
◆Ukusebenza kakuhle kokugquma kunye nobuchule obunamandla bokuchasana nongcoliseko;
◆Inokuxhotyiswa ngeembumbulu okanye izixhobo zokusebenza zamapolisa zombane, ezisebenza ngokuthembekileyo ngoomatshini kunye nokusebenza rhoqo;akukho bungozi bomlilo kunye nokudubula;
◆ I-transformer yangoku eyakhelwe-ngaphakathi, ukuchaneka komhlohli kufikelela kwi-0.2, enokuqonda ukukhuselwa okuhlangeneyo kwezigaba ezintathu;
◆ Isilawuli sokunciphisa siqhotyoshelwe, esinokugcina isiphaluka sivulekile kwaye sisebenze ngokuthembekileyo phantsi kobushushu obuthile kunye nomswakama.

Sebenzisa iMiqathango yokuSingqongileyo

◆ Iqondo lokushisa lomoya we-Ambient: umda ophezulu +40 ℃, umda ophantsi -30 ℃;
◆Altitude: 200.0m (ukuba i-altitude ifuna ukwandiswa, iqondo lobushushu elilinganisiweyo liya kwandiswa ngokufanelekileyo),
◆ Uxinzelelo lomoya: akukho ngaphezulu kwe-700.Pa (ilingana nesantya somoya esiyi-34m/s),
◆Ubungakanani benyikima: Iqondo lenyikima B isidanga z
◆Inqanaba longcoliseko: Ⅲ inqanaba;
◆ Owona mahluko wobushushu bemihla ngemihla: awukho ngaphezulu kwe-25℃
