Zamagetsi masiwichi mpweya: kufotokoza, akuti

Gasi amalimata dera baka ichidachi - ndi kusinthitsa chipangizo, amene chimagwiritsidwa ntchito makhazikitsidwe magetsi ndi kalasi voteji pa 6 ndi 220 kV. Mu mpweya magetsi (sulfure hexafluoride) akutumikira monga zokutira zitsulo ndi Arc wozimitsa chipangizo sing'anga. Bwaloli ndi mankhwala wofooka, wopanda choipa, si flammable gasi, amene ali kwambiri matenthedwe madutsidwe ndi kukana magetsi. Ubwino mpweya magetsi monga mfundo kuti sikutanthauza monga mafuta thiransifoma, chisamaliro alibe zopweteka pa ndondomeko ya chipangizo (pansi ntchito yachibadwa) popanda ukalamba, ndipo mwa zina, ndi wotsika.

sulfure hexafluoride lophimba zikuphatikizapo chipangizo kumatula amene amakhala ndi kumanga yosavuta miyeso yaing'ono. Kuthetsa Arc chikuchitika ndi chiswa ochepa ndipo mwamsanga. Tsopano tiyeni tione pa zifukwa ziti Arc lakhala mu makina ndi kapangidwe ake. Sulfa hexafluoride dera baka ichidachi zikuphatikizapo mizati atatu. Aliyense wa iwo ndi hermetic zitsulo chidebe wodzala wothinikizidwa pa mavuto 0,6 MPa sulfure hexafluoride. Aliyense mzati lili chipangizo avtopnevmaticheskoe kwa wozimitsa Arc.

Ubwino masiwichi magetsi mpweya:

- kuthekera ntchito magetsi makhazikitsidwe a boma ndi ena Kukwanilitsa magulu onse voteji;

- kudalirika ndi kuphweka kwa kapangidwe;

- amtengo yaikulu ya kusintha dongosolo kukhudzana;

- kumatula mphamvu zabwino;

- mkulu mlingo yankho;

- moto ndi kuphulika;

- otsika kulemera ndi miyeso yaying'ono.

lophimba sulfure hexafluoride angapo a zovuta:

- zofunika khalidwe mpweya za magetsi;

- kagwiritsidwe ntchito kazipangizo chapadera chimene chili chofunika chifukwa tikukonza nthawi ya kusintha zipangizo;

- pa ntchito ya chipangizo mtundu zoipa mankhwala kuti thupi - fluorides.

Komabe, ngakhale zovuta izi, masiwichi wa mtundu uwu ndiwo lalikulu mpikisano mafuta ndi mpweya switchgear.

Mtundu gasi amalimata chipangizo lakonzedwa kuti ntchito mu nyengo yovuta kwambiri ndi mmene chilengedwe. Mwachitsanzo, masiwichi (110 kV) magetsi mpweya angathe zikugwira ntchito pa kutentha yozungulira kwa -35 kuti +40 madigiri Celsius, angathe kuikidwa pa msinkhu wa mamita oposa chikwi pamwamba pa nyanja. Mu ntchito zipangizo ngati zimenezi chinagwira m'zinthu ndi yambitsa chipangizo. Pamene ukugwira ntchito lophimba mkati oveteredwa mtengo zikusinthira (2000 A), ndi wokhoza kuchita kusagwirizana ntchito nthawi 6000, ndipo pansi mwadzidzidzi mode umadutsa izo, nthawi zambiri yochepa dera panopa, ndipo zida za ungam'chititse m'zinthu 400 okha kuchoka. Sulfa hexafluoride lophimba (35 Q) ali mlingo panopa kuposa zipangizo anaikira 110 KW, zinali 3150 A ndi oveteredwa kuswa apano - 50 Ka. zipangizozi anapangidwa kuti pachimake kwambiri kuchokera - 127,5 Ka.

Pomaliza, kuwonjezera kuti mpweya ndi dera mafuta breakers pang'onopang'ono kupereka njira kwa switchgear gasi insulated ndi kuyamwa. Izi zingathe kufotokozedwa ndi makhalidwe arcing yosiyanasiyana ya mpweya ndi zingalowe, komanso kuchuluka ntchito chitetezo cha zipangizo.
