Itshintshela igesi zombane: inkcazelo, isikhundla

Gas-zigqunyiwe umaphuli yesekethe - a isixhobo ziguquka, nto leyo lisetyenziswa kufakelo zombane neklasi ombane ukusuka kwisi-6 ukuya 220 kV. Lwegesi yombane (sulphur hexafluoride) ukhonza ubushushu arc isixhobo medium zokuchela. Iluphawu iikhemikhali engasebenziyo, ongenabubi, igesi non-ezinokutsha, nto leyo eye conductivity ezibalaseleyo thermal kunye nokumelana zombane. Izinto eziluncedo berhasi sombane ziquka yokuba ingakufuni njengoko oyile sombane, ukhathalelo alunasiphumo umonakalo kwi kuyilo yecebo (phantsi ukusetyenziswa eziqhelekileyo) bangaluphali, kunye, phakathi kwezinye izinto, liphantsi kakhulu.

sulphur hexafluoride switsha kuquka isixhobo uqhekeke esibonakala yi zokwakha ezilula kunye nomlinganiselo ezincinane. icima arc ithatha indawo breaks ezimbalwa kunye ngokukhawuleza. Ngoku cinga ngoko ngokusekelwe kwi arc ucimayo kwi umatshini kunye neempawu zayo zoyilo. Isalfure full hexafluoride sihlanganisa izibonda ezintathu. Ngamnye kubo isikhongozelo metal hermetic leyo izaliswe zixinaniswe phantsi koxinzelelo ka 0.6 MPA sulphur hexafluoride. ipali nganye ibekwe isixhobo avtopnevmaticheskoe ngenxa zokucima i arc.

Izinto eziluncedo itshintshela igesi zombane:

- amathuba ukusetyenziswa kufakelo zombane karhulumente kunye nawabucala nasekunyanzelisweni zonke iiklasi ombane;

- ukuthembeka kunye nokusebenziseka loyilo;

- sisibonelelo elikhulu wayicima inkqubo contact;

- umthamo elungileyo nokudilizwa;

- izinga impendulo eliphezulu;

- umlilo dubulo;

- ubunzima eliphantsi kunye nomlinganiselo compact.

shintsha sulphur hexafluoride lineqela ethile:

- iimfuno esemgangathweni igesi yombane;

- ukusetyenziswa kwezixhobo ezizodwa, apho kuyimfuneko yolondolozo lwamathuba ubane izixhobo;

- ngexesha nokusebenza ifomu isixhobo kweziyobisi yingozi emzimbeni womntu - Imichiza.

Noko ke, nangona ezi kubakho iingxaki, itshintshela le hlobo zenza kakhulu oyile ukhuphiswano kunye nomoya nokucima.

Uhlobo gas-zigqunyiwe isixhobo yenzelwe ukusebenza kwimozulu nzima kakhulu neemeko zokusingqongileyo. Umzekelo, ixesha sokuyivula (110 kV) igesi zombane ekwaziyo ukusebenza kwiqondo lobushushu okukufutshane ukusuka degrees -35 ukuya +40 Celsius, zingafakwa kwi kubude ngaphezu kwewaka leemitha ngaphezu komphakamo wolwandle. Xa ukusebenza izixhobo ezifana babathimba imijikelo kwaye uvule ifowuni. Xa usebenza switsha phakathi ixabiso yangoku rated (2000 A), ukuba unako ukwenza umsebenzi ngampela amaxesha 6000, naphantsi likaxakeka imo kungenela singenelayo, ngokuqhelekileyo elifutshane-wesekethe ngoku, yaye izixhobo ekwaziyo ukwenza imijikelo 400 kuphela off. Isalfure hexafluoride tshintshela (35 q) owaziwayo yangoku obungaphezu lwezixhobo ezenzelwe ukulungiselela 110 Township, kwaba 3150 A kunye kayi ligqobha yangoku - 50 ka. Ezi zixhobo zenzelwe kwincopho kakhulu off - 127,5 ka.

Xa ndiqukumbela, sidibanisa ukuba umoya kunye yesekethe oyile amaza ngcembe ukunika indlela eya nokucima gas-zigqunyiwe kunye cleaner. Oku kuchazwa ngeempawu arcing ezahlukeneyo ze gesi kunye lwepolitiki, kwakunye nokwanda ukhuseleko yokusebenza izixhobo.
