Main technical parameters

Product Feature

SF6 insulating medium
SF6 yakanyatsokodzera kuvharisa uye arc yekudzima svikiro nekuda kweiyo yakanyanya kupisa kupisa simba, iyo inogona kukurumidza kuparadzira kupisa panguva yekupisa kwearc, yakanyanya kupisa conductivity pazero ikozvino, iyo inogona kuita kuti arc itonhore uye humwe hunhu hwepamusoro.
Kuiswa chisimbiso kwakanaka
Iyo gasi tangi yakagadzirwa ne2mm simbi isina tsvina yakaumbwa uye yobva yaiswa weld, uye inotakura pane Stainless simbi switch shaft inotora yakakosha kaviri-layer sealing chimiro, iyo inova nechokwadi chekuti gasi tangi rine yakanaka kwazvo kusimba kwemhepo. SF6 gasi iri ≤0.01%.Ita shuwa kuti hupenyu hwechishandiso hunopfuura makore makumi matatu.
Compact uye kugadzirisa-isina
Chigadzirwa chinotora modular dhizaini, compact chimiro, diki tsoka, kuisirwa nyore uye kugadzirisa-yemahara.
Automation interfaces
Iyo switch ye motor-drive unit yakachengeterwa iyo interface yekugovera network otomatiki, uye kubatana neRTU kuri nyore uye kuri nyore.Nzvimbo yekuisa RTU yakachengetwa mu cabinet.
Advanced Processes
Gasi tangi yekugadzira chaiyo, kushandiswa kwelaser yekucheka uye CNC kubaya, kudzikisira, kupeta uye zvimwe midziyo kuona kuti iyo dimensional chaiyo yegasi tangi zvikamu kugadzirisa, kushandiswa kwemarobhoti welding, otomatiki welding process kuti ive nechokwadi chepamusoro welding kunyatsoshanda, yakagadzikana mhando. yetangi yegasi, weld seam yakanaka, kudzivirira kubuda kwegasi mutangi regesi uye kupinda kwehunyoro kubva kunze, kuwedzera kuchengetedzwa kweSSU akateedzana inflatable makabati, kuita kwekugadzikana kwekabati.
Nzira yekubatanidza busbar
Iyo yemukati koni casing yakaiswa padivi peiyo switchgear kabati, ichishandisa silicone rabha sechinhu chinodzivirira, uye inoshandiswa kuona kushandiswa kwemhando imwechete yemhete main unit ine akasiyana akajairwa mabhokisi mayuniti kana imwe gasi kamuri kuburikidza nebhazi rekubatanidza. kuisa pamwe chete cabinet.
Zvishandiso zvinoputika
Tangi rega rega rakaiswa membrane inoputika-yekudzivirira yakarongedzerwa pamusoro pe 0.2MPa kuti isunungure kudzvanywa muchiitiko chekutadza kushanda.Iyo membrane isina moto inogona kuiswa pazasi kana pamusoro petangi.

Optional Configuration

Mhosva Indicator
Mhosva zviratidzo zvinoshandiswa zvakanyanya mumhando dzakasiyana-siyana dzemhete main unit, high-voltage switchgear uye tambo yebazi bhokisi remagetsi system, iyo inogona kunyatsoona uye nekuvimbika kuona chikamu chekukanganisa uye kukanganisa mhando yemagetsi grid.Kushandiswa kwetambo pfupi-yepasi pasi chiratidzo chemhosva inzira inobudirira yekuwana kukanganisa kwetambo, inzira inobatsira yekuvandudza kushanda kwehutano hwekugovera network uye kubudirira kwekubata njodzi.Yakaderera simba rekushandisa dhizaini, yakakwirira-inogoneka lithium bhatiri kana kunze kwesimba rekupa, hupenyu hurefu hwebhatiri;chimiro chekunze uchishandisa kadhi-mhando dhizaini, muchina wese uri nyore uye nyore kurodha uye kurodha.

Microcomputer Dziviriro Chishandiso
Chigadzirwa chekudzivirira microcomputer chinozvimiririra chine zvakanakira kubatanidzwa kwepamusoro, kuchengetedzwa kwakazara, kugona kwakasimba kurwisa-kupindira, kuderera kwesimba rekushandisa, kupikisa nharaunda dzakaomarara, nezvimwe. Iyo inonyanya kukodzera kuisirwa yakananga kuiswa mu switchgear cabinet kuti uone kuyerwa. , kutarisa, kutonga, kudzivirira, kutaurirana uye mamwe mabasa echikwata chechikwata chechikwata.Kuzvidzivirira-powered microcomputer kuchengetedza uye inoshanda microcomputer inogona kusarudzwa zvinoenderana nezvinodiwa chaizvo, uye kambani yedu ichapa akawanda-mhando sarudzo.

Current Transformer
Yazvino transformer yakavakirwa pamusimboti we electromagnetic induction ichava chikamu chekutanga cheyazvino muchikamu chechipiri cheiyo diki yekuyera magetsi, kudzivirira relay, otomatiki kutonga uye zvimwe zvishandiso zvekupa masaini emagetsi emagetsi, kuita basa kuchengetedzwa uye kutariswa kwemidziyo yekutanga, kuvimbika kwebasa rayo pakushanda kwakachengeteka kwesimba rose resimba kune kukosha kukuru.
