Whakakā hau Electric: whakaahuatanga, ti'araa

Gas-kiriweti ara iahiko takahi - he pūrere whakawhitinga, Kei te whānui i whakamahia i roto i ngā utanga hiko ki te piha ngaohiko i 6 ki te 220 kV. I roto i te hau hiko (whanariki hexafluoride) tavini rite te tuuraa me pewa tupohe i pūrere reo. tohu te reira i te, te kinokore, hau kore-pūkākā matū hohekore, e kua pai kawe ia waiariki me te ātete hiko. Ko te painga o te hau hiko ngā te meka e kore e rapua e te reira rite te hinu hiko, tiaki e kore pānga totohu i runga i te hoahoa o te pūrere (i raro i te whakamahi noa) kahore toulekeleká, a, i roto i era atu mea, he āhua iti.

whanariki hexafluoride whakakā ngā te pūrere pakaru āhuatanga nei i te hanga māmā, me ngā āhuatanga iti. tinei pewa e wahi ki torutoru pakaru, me te hohoro. Na whakaaroa i runga i te mea pūtake te pewa tinei i roto i te mīhini me ona āhuatanga hoahoa. Pūngāwhā hexafluoride haaati kaiwahi ngā toru amo. Ia o ratou ko te ipu whakarewa hermetic ki tonu nei i te kōpeke i raro i te pēhanga o 0.6 MPa whanariki hexafluoride. Kei ia pou te pūrere avtopnevmaticheskoe mō te tupohe i te pewa.

Painga o whakakā hau hiko:

- te taea o te whakamahi i roto i ngā utanga hiko uruhi tūmatanui, me te tūmataiti o ngā akomanga ngaohiko katoa;

- tika, me te tapatahi o te hoahoa;

- he rauemi nui o whakawhiti te pūnaha whakapā;

- kaha pakaru pai;

- he auau whakautu tiketike;

- ahi me te pahūtanga;

- taimaha iti me āhuatanga kiato.

whakakā he maha o drawbacks whanariki hexafluoride kua:

- whakaritenga kounga mo te hau hiko;

- te whakamahi o te taputapu motuhake, i te mea e tika ana mo te tiaki wā o whakawhiti whakaaro;

- i roto i te mahi o te taonga kino puka pūrere ki te tinana tangata - fluorides.

Heoi, ahakoa enei drawbacks, whakakā o tenei momo kėia he hinu whakataetae, me te rangi switchgear nui.

pūrere hangaia ki te mahi i roto i te rangi tino uaua me ngā āhuatanga taiao Momo hau-kiriweti. Hei tauira, He huri (110 kV) hau hiko e taea o mahi i pāmahana ambient i -35 ki +40 degrees, e taea te tāuta i te teitei o neke atu i te kotahi mano mita ki runga ake te taumata moana. I roto i te mahi o taua whakaaro kawea atu huringa me whakahohe te pūrere. A, no te mahi whakawhiti i roto i te uara tauanga o nāianei (2000 A), he taea ki te mahi i te mahi momotu 6000 wa reira, a i raro i ohotata haere aratau roto reira, te tikanga o nāianei poto-iahiko, me te taputapu e taea o mau ana i roto i 400 anake huringa atu. Pūngāwhā hexafluoride whakakā (35 q) he whakatauranga nāianei nui atu taua o ngā pūrere hangaia mō te 110 KW, ko reira 3150 A me te tauanga whawhati nāianei - 50 KA. E hangaia ēnei whakaaro mo te tihi tino atu - 127,5 KA.

I roto i te mutunga, tāpiri tatou e te hau, me te hinu iahiko tuatea āta hoatu ara ki te switchgear hau-kiriweti me korehau. Ka taea te faataa tenei e rerekē ngā āhuatanga arcing o te hau me te korehau, me te nui haere haumaru whakahaere o te taputapu.
