Electric gas sauya: description, nadi

Gas-makaran kewaye wato Ubangiji Yesu Kristi - wani sharuddan sauyawa na'urar, wanda aka yadu a yi amfani da wutar lantarki shigarwa tare da irin ƙarfin lantarki aji daga 6 zuwa 220 KV. A lantarki gas (sulfur hexafluoride) hidima a matsayin insulating kuma baka extinguishing matsakaici na'urar. Yana wakiltar wani chemically m, m, wadanda ba flammable gas, wanda yana da kyau kwarai thermal watsin da lantarki juriya. A abũbuwan amfãni daga lantarki gas hada da cewa shi ba ya bukatar a matsayin gidan wuta mai, kula da babu tareda žata sakamako a kan zane na na'ura (ƙarƙashin amfani na al'ada) ba tare da tsufa, da kuma, a tsakanin sauran abubuwa, shi ne in mun gwada low.

sulfur hexafluoride canza hada da BREAKING na'urar wanda aka halin sauki yi da kuma kananan girma. baka quenching daukan wuri tare da 'yan karya da kuma da sauri. Yanzu la'akari a kan abin da dalilin da baka quenching a cikin na'ura da ta zane fasali. Sulfur hexafluoride kewaye wato Ubangiji Yesu Kristi ya hada da uku sanduna. Kowane daga cikinsu shi ne wani hermetic karfe ganga wanda aka cika da matsa a karkashin wani matsin lamba na 0.6 MPa sulfur hexafluoride. Kowane iyakacin duniya da aka located avtopnevmaticheskoe na'urar for extinguishing da baka.

Abũbuwan amfãni daga lantarki gas sauya:

- da yiwuwar amfani a lantarki shigarwa jama'a da kuma masu zaman kansu tilasta yin aiki da duk ƙarfin lantarki azuzuwan.

- AMINCI da sauki zane.

- wani babban hanya na sauya sheka da lamba tsarin.

- kyau BREAKING iya aiki.

- wani babban martani kudi.

- wuta da fashewar.

- low nauyi da kuma m girma.

canza sulfur hexafluoride yana da yawan drawbacks:

- ingancin bukatun ga lantarki gas.

- yin amfani da musamman kayan aiki, wanda wajibi ne ga lokaci-lokaci ana gyara na sauya sheka na'urorin.

- a lokacin aiki na na'urar form cutarwa abu ga jikin mutum - fluorides.

Duk da haka, duk da wadannan drawbacks, sauya daga irin wannan dokoki ne mai tsanani gasar man fetur da kuma iska switchgear.

Type gas-makaran na'urar tsara aiki a wuya sosai weather da kuma muhalli da yanayi. Alal misali, sauya (110 KV) lantarki gas iya aiki a yanayi yanayin zafi daga -35 zuwa +40 digiri Celsius, za a iya shigar a wata tsawo na fiye da dubu mita saman teku matakin. A cikin aiki na irin wannan na'urorin ya kwashe hawan keke da kuma kunna na'urar. Lokacin aiki canji a cikin rated halin yanzu darajar (2000 A), shi ne iya yi a raba aiki 6000 sau, kuma a karkashin gaggawa yanayin wuce ta wurin shi, yawanci short-kewaye halin yanzu, da kuma na'ura iya dauke da fitar kawai 400 hawan keke kashe. Sulfur hexafluoride canji (35 q) yana da wani halin yanzu rating mafi girma fiye da na na'urorin tsara don 110 kW, shi ne 3150 A da rated watse halin yanzu - 50 Ka. Wadannan na'urori ana tsara don mafi kashe ganiya - 127,5 KA.

A ƙarshe, mun ƙara da cewa iska da kuma mai kula da da'ira hutu hankali ba da hanya ga gas-makaran switchgear da injin. Wannan za a iya bayyana ta daban-daban arcing halaye na gas da kuma injin, kazalika ya karu sarrafawa aminci daga cikin kayan aiki.
