Electric igesi ukushintshwa: incazelo, isiqu

Negesi-ngci wesifunda full - a idivayisi usuke, okuyinto kabanzi ukufaka kagesi nge class voltage-6 kuya 220 kV. Ngo igesi kagesi (sulphur hexafluoride) ukhonza njengomdala ekuvikeleni kanye arc zokucisha kudivayisi ophansi. Lokhu kusho ngasebenzi amakhemikhali, emsulwa, igesi okungezona oluvuthayo, okuyinto ine omuhle kakhulu conductivity ezishisayo futhi ukumelana kagesi. Izinzuzo igesi kagesi zihlanganisa iqiniso ukuthi akudingi njengoba uwoyela transformer, ukunakekelwa ayinakho zilimaze umklamo zedivayisi (ngaphansi ekusebenziseni ifoni okuvamile) bengasagugi, futhi, phakathi kwezinye izinto, kuqhathaniswa ongaphakeme.

sulphur hexafluoride inkinobho kuhlanganisa idivayisi kuphulwa esibonakala by ukwakhiwa elula Ubukhulu ezincane. eqeda arc senzeka ngekhefu ezimbalwa futhi ngokushesha. Manje cabanga ngalokho ngesisekelo the arc eqeda emshinini nezici nomklamo walo. Sulphur hexafluoride wesifunda full kuhlanganisa izingongolo ezintathu. Ngamunye wabo kuyinto hermetic isitsha kwensimbi eligcwele onomfutho kwengcindezi ka 0.6 MPA sulphur hexafluoride. isigxobo ngamunye itholakala kudivayisi avtopnevmaticheskoe ngoba ekucimeni arc.

Izinzuzo kagesi igesi ukushintshwa:

- kungenzeka ukusetshenziswa e ukufaka kagesi ukuphoqelelwa obala langasese ngezenzo wonke amakilasi voltage;

- nokwethenjelwa inkimbinkimbi design;

- umthombo enkulu ukushintsha uhlelo contact;

- kuhle kuphulwa umthamo;

- a high Ukusabela rate;

- umlilo kanye nokuqhuma;

- isisindo ongaphakeme nobungako ezihlangene.

inkinobho sulphur hexafluoride enezinto eziningi nemiphumela ethile engathandeki:

- nezidingo izinga zikaphethiloli kagesi;

- ukusetshenziswa imishini ekhethekile, okuyilona elidingekayo ukuze umuntu yesondlo ngezikhathi ukushintsha amadivayisi;

- ngesikhatsi operation yefomu kudivayisi izidakamizwa eziyingozi umzimba womuntu - fluorides.

Nokho, naphezu kwalezi nemiphumela ethile engathandeki, ukushintsha yalolu hlobo umthetho uwoyela mncintiswano futhi emoyeni switchgear sina.

Uhlobo igesi-ngci idivayisi yakhelwe ukusebenza sezulu nzima kakhulu nezimo zemvelo. Ngokwesibonelo, sekuqalile (110 kV) igesi kagesi uyakwazi ezisebenza at okushisa ambient kusukela degrees -35 kuya +40 Celsius, ingafakwa ezingeni ukuphakama engaphezu kwenkulungwane amamitha ngaphezu kolwandle. Ngo ukusebenza amadivayisi enjalo kumukwe imijikelezo futhi kusebenze kudivayisi. Lapho eqhuba inkinobho ngaphakathi ukalwe Inani lamanje (2000 A), ikwazi ukwenza operation unqamule izikhathi 6000, nangaphansi eziphuthumayo imodi sidlula ke, ngokuvamile isekhethi samanje, futhi ama-apharathasi ukufeza imijikelezo 400 kuphela off. Sulphur hexafluoride switch (35 q) has a isilinganiso zamanje obukhulu kunobukaJohane amadivayisi eyenzelwe 110 KW, kwaba 3150 A kanye ukalwe breaking wamanje - 50 KA. Lezi amadivayisi zenzelwe eliphakeme off kakhulu - 127,5 KA.

Ekuphetheni, siye sinezele ukuthi umoya uwoyela wesifunda amadlambi kancane kancane akhale switchgear igesi-ngci kanye cleaner. Lokhu zingachazwa ngezinqubo ezihlukahlukene arcing izici igesi kanye cleaner, kanye lenyuka ukuphepha zokusebenza imishini.
