GHXH-12 yekuchengetedzwa kwezvakatipoteredza gasi insulated ring main unit series izere seti yemagetsi ekugovera midziyo ye12kV, matatu-chikamu AC 50Hz, bhazi rimwe chete uye imwechete bhasi segmented system. Chigadzirwa chacho chine hunhu hwechimiro chakareruka, kuchinjika kushanda, kuvharika kwakavimbika, kuisirwa nyore, nezvimwe. Inogona kupa zvinogutsa zvigadziriso zvehunyanzvi zvezviitiko zvakasiyana zvekushandisa uye vashandisi vakasiyana. Kugamuchirwa kwehunyanzvi hwekunzwa uye tekinoroji yeruzivo, pamwe nekuita kwehunyanzvi uye zviri nyore uye zvinochinjika zvigadziriso zvirongwa, zvinogona kusangana nezvinogara zvichichinja zvinodiwa zvemusika uye zvakakodzerwa nezvinodiwa zvehungwaru hwegridi.
Iyo GHXH-12 yekuchengetedzwa kwezvakatipoteredza gasi insulated ring main unit series inokodzera maindasitiri nevagari tambo mhete network uye kugovera network terminal mapurojekiti. Sekugamuchirwa uye kugoverwa kwesimba remagetsi, inonyanya kukodzera kugoverwa kwemagetsi munzvimbo dzinogara maguta, zviteshi zvidiki zvechipiri, zviteshi zvekuvhura nekuvhara, mabhokisi ebazi remabhokisi, mabhokisi emhando yezviteshi, maindasitiri nemabhizinesi emigodhi, zvitoro, nhandare dzendege, nzira dzepasi pevhu. , kugadzirwa kwemagetsi emhepo, nhandare , njanji, tunnels nedzimwe nzvimbo dzinoshandisa.
GHXH-12 kuchengetedzwa kwezvakatipoteredza gasi-insulated ring main unit series inosangana nemitemo yenyika, zviyero zveindasitiri yemagetsi uye mamwe maitiro. Shanduko dzayo uye zvikamu zvikuru zvemagetsi zvakabatanidzwa mamodules, zvikamu zvinofambisa pakati pezvikamu zvitsigiro zvakasimba, iyo wiring yekunze inotora majoini akavharidzirwa etambo, uye iyo inoshanda unit yekubatanidza bhazi inotora akavharidzirwa insulated mabhazi. Nokudaro, kuchengetedzwa kwekushandiswa kunovandudzwa zvikuru, nzira yekushanda inotora chitubu chemvura, uye hupenyu hwemagetsi hunodarika 10,000 nguva. Iyo data yekushanda kwayo uye mamiriro emidziyo inogona kutariswa uye kutariswa kure, uye inogona kuve isina kutarisirwa. Isimba rekugovera simba rine rudzi rwekuita.
Aya mayunitsi anotevera anogona kusarudzwa mukhabhineti kuti agadzire ehupfumi uye inoshanda magetsi ekupa unit:
1. Vacuum circuit breaker unit (630A, 20-25kA)
2. Vacuum load switch unit (630A, 20-25kA)
Product Features
1. Kuchengetedza kwezvakatipoteredza
Zvese zvinoshandiswa mukugadzira zvigadzirwa hazvisi-chepfu uye zvisingakuvadzi zvinhu. N2 kana mhepo yakaoma inoshandiswa senge insulating medium kudzikisa greenhouse gasi kubuda uye kuzadzisa zvinangwa zvekuchengetedza kwezvakatipoteredza. Hapana zvinhu zvine chepfu uye zvinokuvadza zvinoburitswa panguva yekushandiswa. Inogona kudzokororwa uye kushandiswa zvakare, iyo inosarudza kuchengetedzwa kwezvakatipoteredza kwekushandiswa.
2. Yakasiyana-siyana yekushandisa
Usashandise chero magasi ane chepfu uye anokuvadza, ayo anosarudza kuchengetedzwa kwenzvimbo yekushandisa. Kungave mudzimba dzepasi, mumatanho, pazvikepe, uye munzvimbo dzakasiyana siyana mukati nekunze. Mukati meimba yepamusoro-soro inogona kuzadzwa nemhepo yakaoma kana nitrogen, iyo inokodzera mamiriro ezvinhu akaoma akadai se: kukwirira kwakakwirira, mhepo ine simba uye jecha, kutonhora kwakadzika, kutonhora kwakanyanya, kudiwa kwekuchengetedzwa kwezvakatipoteredza, nzvimbo dzinowanzoshanda, dzakachengeteka. nzvimbo dzinodzivirira kuputika, mhute ine munyu yakawanda, uye kushandiswa kwakachengeteka pasi pemamiriro ekugadzirisa. Yakanyatsovharwa uye yakavharwa zvakakwana, yakakodzera kuti midziyo irambe ichishanda mushure mekutora mamwe matanho ekuchenesa nekuomeswa mushure mechinguva chiduku chekupinda kwemvura.
3. Kuchengetedza-pasina
Pamusoro peiyo inoshanda sisitimu, iyo GHXH-12 yekuchengetedzwa kwezvakatipoteredza gasi-insulated ring main unit series iri munzvimbo yakavharwa zvizere, iyo yakakwira-voltage switch chikamu chakavharwa zvachose, kuitira kuti kuchenesa uye kugadzirisa kunogona kudziviswa, uye mutengo we kushanda nekugadzirisa zvinogona kuderedzwa.
Iyo dhigirii yeautomation ye switchgear yakakwira zvakanyanya, uye iyo online yekuona basa inozivisa mushandisi nezve mashandiro emidziyo munguva chaiyo, iyo inonyanya kubatsira kune otomatiki yekugovera network, inoderedza mutengo wekushanda kwevashandi, uye inoderedza mutengo wekugadzira wemakambani emagetsi.
4. Kuchengetedzwa kwepamusoro
Yakakwana inopindirana uye inopindirana sisitimu, iyo-nhatu-chikamu yekuzvitsaura chinhambwe inoonekwa zvakajeka, ichidzivirira kuitika kwetsaona yekukanganisa. Iko kushandiswa kweSF6 gasi kunodzimwa, uye iyo interphase yekuzviparadzanisa chimiro inosimbiswa kudzivirira kuwedzera kana kuputika njodzi inokonzerwa nepfupi pfupi pakati pezvikamu kana akawanda maseketi. Iyo vacuum interrupter ine vacuum simba rekuputika-proof chengetedzo gasi kabati inotambirwa, uye danda rakasimba-rakavharwa rine kumwe kuchengetedza kuita kwekuchinja.
5. Easy kushanda
Iyo disconnector uye pasi switch ine chete mubato wekushanda, uye hapana chikonzero chekuziva uye kunetseka pamusoro pezvikanganiso. Kana iyo yedunhu ichishanda, mubato wekushanda we disconnectora uye pasi switch haigone kushandiswa, uye yakaoma kudzidziswa kwehunyanzvi haidiwi, izvo zvinoita kuti kuvhiya kuve nyore, kudzivirira zvikanganiso zvekushandisa.
