Gasi wotetezedwa ndi chilengedwe Ring Main Unit GHXH-12

Mawu oyamba

GHXH-12 chitetezo cha chilengedwe gasi insulated mphete main unit mndandanda ndi seti yathunthu ya zipangizo kugawa mphamvu kwa 12kV, magawo atatu AC 50Hz, single busbar ndi single busbar segmented system. The mankhwala ali ndi makhalidwe a dongosolo losavuta, ntchito kusintha, interlocking odalirika, unsembe yabwino, etc. Ikhoza kupereka zokhutiritsa zothetsera luso ntchito zosiyanasiyana ntchito ndi ogwiritsa ntchito zosiyanasiyana. Kukhazikitsidwa kwa ukadaulo wozindikira komanso ukadaulo wazidziwitso, kuphatikizidwa ndi luso laukadaulo komanso masinthidwe osavuta komanso osinthika, amatha kukwaniritsa zosowa za msika zomwe zimasinthitsa nthawi zonse ndipo ndizoyenera pazofunikira zanzeru zama grid.

Gulu lalikulu la GHXH-12 loteteza chilengedwe la gasi lopangidwa ndi mphete ndi loyenera kumafakitale ndi ma projekiti amagetsi amagetsi ndi ma projekiti ogawa maukonde. Monga kuvomereza ndi kugawa mphamvu zamagetsi, ndizoyenera makamaka kugawira magetsi m'madera okhala m'matauni, malo ocheperako ang'onoang'ono, malo otsegulira ndi kutseka, mabokosi a nthambi, mabokosi amtundu wa bokosi, mabizinesi a mafakitale ndi migodi, malo ogulitsira, ndege, subways. , kupanga magetsi amphepo, masitediyamu, njanji, ngalande ndi malo ena amagwiritsa ntchito.

GHXH-12 chitetezo chilengedwe mpweya wotsekereza mphete main unit mndandanda amakwaniritsa zofunikira dziko, miyezo makampani mphamvu ndi mfundo zina. Zosintha zake ndi zigawo zikuluzikulu zamagetsi ndi ma module ophatikizika, magawo oyendetsa pakati pa magawo ndi mapaketi olimba otchinjiriza, mawaya akunja amatengera zingwe zotetezedwa, ndipo mabasi olumikizirana amatengera mabasi otetezedwa. Chifukwa chake, chitetezo chogwiritsidwa ntchito chimakhala bwino kwambiri, makina ogwiritsira ntchito amatengera njira yamasika, ndipo moyo wamakina ndi nthawi zopitilira 10,000. Deta yake yogwirira ntchito ndi zida zake zitha kuyang'aniridwa ndikuwunikidwa patali, ndipo zitha kusamaliridwa. Ndi chipangizo chogawa mphamvu chokhala ndi mtundu wa ntchito.

Magawo otsatirawa atha kusankhidwa mu nduna kuti apange gawo lazachuma komanso lothandiza lamagetsi:

1. Vacuum circuit breaker unit (630A, 20-25kA)

2. Vacuum load switch unit (630A, 20-25kA)

Zogulitsa Zamankhwala

1. Kuteteza chilengedwe

Zida zonse zomwe zimagwiritsidwa ntchito popanga zinthu ndizopanda poizoni komanso zopanda vuto. N2 kapena mpweya wouma umagwiritsidwa ntchito ngati njira yotetezera kuti muchepetse mpweya wowonjezera kutentha ndikukwaniritsa zolinga zoteteza chilengedwe. Palibe zinthu zapoizoni ndi zovulaza zomwe zimatulutsidwa mukamagwiritsa ntchito. Ikhoza kubwezeretsedwanso ndikugwiritsidwanso ntchito, zomwe zimatsimikizira chitetezo cha chilengedwe cha ntchito.

2. Ntchito zambiri

Osagwiritsa ntchito mpweya uliwonse wapoizoni komanso wowopsa, womwe umatsimikizira chitetezo cha malo ogwiritsira ntchito. Kaya m'zipinda zapansi, mu tunnel, m'zombo, komanso m'malo osiyanasiyana mkati ndi kunja. Mkati mwa chipinda choponderezedwa kwambiri chikhoza kudzazidwa ndi mpweya wouma kapena nayitrogeni, yomwe ili yoyenera pazovuta monga: kumtunda, mphepo yamphamvu ndi mchenga, kutentha kochepa, kuzizira kwambiri, kutetezedwa kwa chilengedwe, malo ogwirira ntchito pafupipafupi, otetezeka. malo osaphulika, chifunga chochuluka cha mchere, komanso kugwiritsidwa ntchito motetezeka pansi pamikhalidwe ya condensation. Zotetezedwa bwino komanso zotsekedwa mokwanira, ndizoyenera kuti zidazo zipitirize kugwira ntchito pambuyo pochita zinthu zina zoyeretsa ndi zowumitsa pakapita nthawi yochepa ya madzi.

3. Zosasamalira

Kuphatikiza pa makina ogwiritsira ntchito, GHXH-12 chitetezo cha chilengedwe cha gasi-insulated mphete yaikulu ya unit ili mu chikhalidwe chosindikizidwa bwino, gawo lapamwamba lamagetsi lamagetsi limasindikizidwa kwathunthu, kuti kuyeretsa ndi kukonza kupewedwe, komanso mtengo wa ntchito ndi kukonza kungachepe.

Mlingo wa automation wa switchgear ndi wokwera kwambiri, ndipo ntchito yodziwikiratu pa intaneti idzadziwitsa wogwiritsa ntchito momwe zida zimagwirira ntchito munthawi yeniyeni, zomwe zimapangitsa kuti ma network ogawa, achepetse ndalama zogwirira ntchito, ndikuchepetsa mtengo wamakampani opanga magetsi.

4. Chitetezo chachikulu

Njira yabwino yolumikizirana komanso yolumikizirana, mtunda wodzipatula wa magawo atatu ukuwonekera bwino, kupeŵa kuchitika kwa ngozi za misoperation. Kugwiritsa ntchito gasi wa SF6 kwathetsedwa, ndipo mawonekedwe odzipatula a interphase amalimbikitsidwa kuti apewe ngozi yakukula kapena kuphulika komwe kumachitika chifukwa chafupipafupi pakati pa magawo kapena mabwalo angapo. Chosokoneza cha vacuum chokhala ndi mphamvu zopumira cha kabati yoteteza zachilengedwe yoteteza chilengedwe chimatengedwa, ndipo mtengo womata wolimba uli ndi chitetezo chinanso chosinthira.

5. Easy ntchito

The disconnector and earth switching ndi chogwirira chimodzi chokha chogwirira ntchito, ndipo palibe chifukwa chodziwira ndikudandaula za zolakwika. Pamene wosweka dera akugwira ntchito, chogwirira ntchito cha disconnector and earth switch sichingagwiritsidwe ntchito, ndipo maphunziro ovuta aukadaulo safunikira, zomwe zimapangitsa kuti ntchitoyi ikhale yosavuta kwambiri, kupewa zolakwika zogwiritsira ntchito.
