YSM6-12/24 unit mtundu SF6 RMU ndi SF6 katundu lophimba monga lophimba chachikulu, nduna lonse ndi oyenera kugawa magetsi zochita zokha ndi yaying'ono komanso expandable zitsulo close switchgear. Imakhala ndi mawonekedwe ake osavuta, magwiridwe antchito osinthika, kutsekeka kodalirika komanso kukhazikitsa kosavuta, ndi zina zambiri, zomwe zingapereke mapulojekiti okhutiritsa aukadaulo pazochitika zosiyanasiyana zofunsira komanso ogwiritsa ntchito. Ndi kukhazikitsidwa kwa ukadaulo wa sensa ndi chitetezo cholumikizirana mpaka pano, kuphatikiza ukadaulo wapamwamba komanso polojekiti yosinthika.

C YSM6-12/24 unit mtundu SF6 RMU akhoza kukwaniritsa zofunikira za msika mosalekeza. Zitha kutenga kudzipangira SF6- 12/24 katundu yopuma lophimba; Njira zogwirira ntchito zosinthira chachikulu mkati mwa mphete yayikulu zitha kukhala zoyendetsedwa ndi manja kapena zamagetsi. Ndipo ikhoza kukwaniritsa zofunikira za "Maulamuliro Anayi" pamene ikufanana ndi FTU ndi RTU.

Chidziwitso: Pakudumpha pang'onopang'ono komanso kuthamanga kwambiri kumatengera kuphatikiza kwa Fuse.

Kwa schema yogawa switchboard

1. Sinthani cholumikizira

2. Kutetezedwa kwa fuse-switch

3. Chitetezo chophwanya kuzungulira

4. Kuyeza kwa MV

5. Ma Casings (Bus Bar Panel)

2. Kutetezedwa kwa fuse-switch

Magawo 5 amtundu wa unit SF6 mphete yayikulu:

1. sinthani cholumikizira cholumikizira cha cubicle ndi cholumikizira chapansi mumpanda wodzaza ndi SF6 ndikukhutiritsa“sealed pressure system ” zofunika.

2. cubicle ya mabasi onse mundege yopingasa yofanana, motero amalola kuti pambuyo pake ma switchboard awonjezere ndi kulumikizana ndi zida zomwe zilipo kale.

3. kyubiki yolumikidzirani yofikira kutsogolo, kulumikiza ku cholumikizira cholumikizira kumunsi ndi malo osinthira ma switch (IM cubicles) kapena zogwirizira m'munsi (ma cubicles a PM ndi QM). Chipinda ichi chilinso ndi

kusinthana pansi kuchokera ku ma fuse a MV a magawo achitetezo.

4. makina ogwiritsira ntchito, kulowetsedwa kumakhala ndi zinthu zomwe zimagwiritsidwa ntchito pogwiritsira ntchito switchdisconnector ndi earthing switch ndi kuyambitsa zofanana.

zizindikiro (kupuma kwabwino).

5. Low voltage cubicle (chapamwamba & m'munsi mpanda dongosolo) kukhazikitsa a

terminal block (ngati njira yagalimoto yayikidwa), ma fuse a LV ndi zida zolumikizirana zophatikizika. Ngati malo ochulukirapo akufunika, mpanda wina ukhoza kuwonjezeredwa pamwamba pa

cubicle.

6. Zosankha zosinthira ma cubicles (IM) zimathanso kuikidwa: kuyendetsa galimoto;

zomangira opaleshoni.

Kulumikizana kozungulira kwa magawo atatu kumayikidwa m'chipinda cha gasi chodzazidwa ndi mpweya wa SF6 ndipo kukakamiza kwachibale ndi 0.4bars. Ili ndi magwiridwe antchito abwino kwambiri ndi chitetezo komanso kudalirika.

● Kulimba:

Chipinda cha mpweya chimadzazidwa ndi mpweya wa SF6, womwe umakwaniritsa zofunikira za "otsekeka kanikizidwe kachitidwe", ndipo ntchito yosindikiza yafufuzidwa ndipo

anawunikiridwa mufakitale.

● Chitetezo Pantchito:

1. Kusintha kuli ndi malo atatu "otsekedwa", "otsegula" ndi "okhazikika", ndipo ali ndi

kutseka ntchito kuti muteteze ntchito mwangozi. Kulumikizana kumayendetsedwa kuti kuzungulire

kasupe wosungira mphamvu zamagetsi, zomwe sizimakhudzidwa ndi zochitika za anthu.

2. Ili ndi "break" ndi ntchito zodzipatula.

3. Kuthekera kopanga kagawo kakang'ono ka SF6 grounding switch kumakwaniritsa zofunikira.

4. Pakachitika ngozi, kupanikizika kumatsika pambuyo poti mpweya woponderezedwa wa SF6 ukudutsa pa diaphragm yachitetezo, ndipo gasiyo amapopera mwachindunji kumbuyo kwa nduna kuti atetezeke.

Kuphwanya mfundo:

Mpweya wa SF6 uli ndi ntchito yabwino kwambiri yozimitsa arc. Pamene kusinthaku kutsegulidwa, kuyenda kwapakati pakati pa arc ndi gasi kuzimitsa arc. Pamene kusuntha ndi static kukhudzana ndi kupatukana, arc amawoneka mu munda electromagnetic opangidwa ndi maginito okhazikika, ndipo arc ndi.

elongated ndi kuzimitsidwa pamene panopa kuwoloka ziro ndi SF6 mpweya. Mtunda pakati pa kusuntha ndi static kulankhula ndi wokwanira kupirira kuchira overvoltage. Dongosololi ndi losavuta komanso lodalirika, lokhala ndi zovala zochepa zolumikizana komanso moyo wautali wamagetsi.

● Chizindikiro cha Switchgear:

Zoyikidwa molunjika ku shaft yoyendetsa, izi zimapereka chizindikiritso chotsimikizika cha malo omwe munthu amalumikizana naye. (zowonjezera A za muyezo IEC 62271-102).

● Lever yogwiritsira ntchito:

Izi zimapangidwira ndi chipangizo chotsutsa-refl ex chomwe chimayimitsa kuyesanso kutsegulanso chipangizocho mutangotseka chosinthira kapena cholumikizira chapansi.

● Chida chotseka:

Pakati pa maloko amodzi ndi atatu amathandizira kuti izi zitsekedwe:

● mwayi wopita ku shaft yosinthika ya chosinthira kapena wozungulira dera

● kulowa kwa shaft yosinthira ya cholumikizira chapansi

● kugwiritsa ntchito batani lotsegulira lomasulidwa. ● Kusintha kosavuta komanso kosavuta

Kuwongolera kwamakina ndi magetsi kuli mbali ndi mbali kutsogolo kwa fascia, pagulu

kuphatikiza chithunzi chosonyeza momwe chipangizocho chilili (chotsekedwa, chotseguka, chodetsedwa):

● Yatsekedwa:

shaft yoyendetsa imayendetsedwa ndi njira yofulumira, yodziyimira pawokha. Palibe mphamvu yomwe imasungidwa mu switch, kupatula pakusintha

ntchito zikuchitika.

Kwa ma fuse ophatikizika osinthira, njira yotsegulira imakhala ndi zida nthawi yomweyo pomwe zolumikizira zimatsekedwa.

● Kutsegula:

chosinthira chimatsegulidwa pogwiritsa ntchito njira yomweyo yochitira mwachangu, yoyendetsedwa mbali ina.

Kwa unit yophatikizika yosinthira fusesi, kutsegula kumayendetsedwa ndi:

● kukankhira-batani

● cholakwa.

● Kulima:

chowongolera c chowongolera chimathandizira kutsegula kapena kutseka kwa zolumikizira pansi. Kufikira ku shaft iyi kwatsekeredwa ndi chivundikiro chomwe chitha kubwezeredwa ngati chosinthira chili

lotseguka koma lomwe limakhalabe lokhoma ngati latsekedwa.

Chizindikiro cha kukhalapo kwa Voltage

Chipangizochi chaphatikiza magetsi amtundu wa VPIS (Voltage Presence Idicating System), mogwirizana ndi muyezo wa IEC 61958, zomwe zimathandizira kupezeka (kapena kusapezeka) kwamagetsi kuti awonedwe pazingwe.

Kusakhudzidwa ndi chilengedwe

● Mpanda wotsekedwa wamkati, uli ndi zigawo zogwira ntchito za LBSkit

(switch, earthing disconnector). Imadzazidwa ndi SF6 molingana ndi matanthauzo a IEC 62271-200 ya "kukakamizidwa kosindikizidwa.

machitidwe".

Kusindikiza kumafufuzidwa mwadongosolo mufakitale.

● Magawo amapangidwa kuti azitha kugawa bwino kwambiri magetsi.
