GVG-12 Solid Insulated Ring Network Switchgear

Overview

GVG-12 yakatevedzana yakasimba insulated mhete network switchgear yakavharirwa zvizere, yakavharwa zvizere, yekuchengetedza-isina yakasimba insulated vacuum switchgear. Yese yakakwira-voltage mhenyu zvikamu zvakaumbwa ne epoxy resin zvinhu zvine hunyanzvi hwekudzivirira, uye vacuum interrupter, main conductive wedunhu, insulating rutsigiro, nezvimwe zvinosanganiswa zvakazara, uye mayuniti anoshanda akabatanidzwa neakazara insulated solid busbar. . Naizvozvo, iyo switchgear yese haina kukanganiswa nekunze kwezvakatipoteredza, uye kuvimbika kwekushanda kwechigadzirwa uye kuchengetedzwa kweanoshanda kunogona kuve nechokwadi.

Iyo ring network switchgear ine hunhu hwechimiro chakareruka, kuchinjika kushanda, kuvharika kwakavimbika, kuisirwa nyore, etc. Inokodzera 50Hz, 12kV simba system, uye inoshandiswa zvakanyanya muindasitiri uye yevagari tambo mhete network uye kugovera network terminal mapurojekiti, se. kugamuchirwa uye kugoverwa kwesimba remagetsi, inonyanya kukodzera kugoverwa kwemagetsi munzvimbo dzekugara mumaguta, zviteshi zvidiki, zviteshi zvekuchinja, mabhokisi ebazi remabhokisi, mabhokisi emhando yezviteshi, maindasitiri nemabhizimusi emigodhi, zvitoro, nhandare dzendege, nzira dzepasi, kugadzirwa kwemagetsi emhepo. , zvipatara, nhandare, njanji, tunnels, nezvimwewo kushandiswa. Nekuda kwekuti chigadzirwa chine zvakanakira zve insulate zvakazara, chisimbiso chakazara, uye chakadzivirirwa zvizere, chakanyanya kukodzera kushandiswa munzvimbo dzakakwirira, tembiricha yepamusoro, kunyorova kupisa, kutonhora kwakanyanya, uye kusvibiswa kwakanyanya.

Chigadzirwa Chimiro

● GVG-12 switchgear inonyanya kuve nemhando nhatu dzezvikamu zvinoshanda, zvinoti V unit (circuit breaker unit), C unit (load break switch unit), uye F unit (yakasanganiswa magetsi unit). Kana iyo sisitimu ichida akawanda mayuniti kuti agadziriswe, anogona kuwedzeredzwa neruboshwe nekurudyi mativi uye akarongwa zvinoenderana neakasiyana dhizaini zvirongwa kuti zvizadzise zvinodikanwa zvekugadzirisa.

● Chikamu chimwe nechimwe chakakamurwa kuita zvikamu zvitatu: kamuri yezviridzwa, mashandiro ekushandisa, uye dunhu rekutanga. Imba yezviridzwa inogona kuve neiyo microcomputer kuchengetedza (akangwara controller) uye mamwe mita. Iyo yekushandisa mashandiro ndeye yakatsaurirwa chitubu chekushandisa, kana magetsi ekushandisa; iyo yekutanga dunhu inotora APG otomatiki gel maitiro, yakanyatso nyudza bhawa yebhazi, disconnector uye vacuum interrupter mu epoxy resin, uye shandisa yakazvitsaurira yekubatanidza uye mabara ebhazi kubatanidza.

● GVG-12 yakasimba-insulated switchgear ine zvakanakira compact structure, yakazara insulated, hupenyu hurefu, kuchengetedza-kusina, nzvimbo duku yekushanda, kuchengeteka uye kuvimbika, uye haikanganisi nemamiriro ekushanda. Inoshandiswa zvakanyanya mumaindasitiri uye ehurumende mhete network uye terminal magetsi emagetsi. Kunyanya akakodzera zviteshi zvidiki zvekugovera magetsi echipiri, kuvhura nekuvhara zviteshi, maindasitiri uye mabhizinesi emigodhi, nhandare dzendege, njanji, nzvimbo dzekutengesa, zvivako zvepamusoro-soro, migwagwa mikuru, nzira dzepasi pevhu, tunnels nedzimwe minda.

Features

Yakanakisa kuita epoxy resin

● GVG-12 yakasimba insulated yakazara yakavharirwa switchgear inogadzirwa nekushandisa yakakosha epoxy resin sechinhu chekudzivirira. Iyi epoxy resin ine yakanakisa zvivakwa:

○ Iine zvakanakisa zvekudzivirira magetsi. Dielectric simba 20-30kV / mm, vhoriyamu resistivity (pv) 1 × 1013-15Ω.m;

○ Kupisa kwekudzivirira kunogona kusvika kupfuura 200 ℃, uye ine yakanaka yekudzivirira kuita pakupisa kwepamusoro;

○ Kugadzikana kwemakemikari zvimiro, zvakanakisa alkali kuramba, asidi kuramba uye solvent kuramba, uye zvakanaka kuramba tembiricha kuchembera uye kuchembera mwaranzi;

○ Thermal conductivity is 80×10-2~100×10-2W/mk, zviri nyore kubvisa kupisa;

○ Iyo ine yakakwirira kunamatira kune akasiyana zvinhu, yepedyo mamorekuru chimiro, yakakwira mechaniki simba, uye kuchengetedzwa kwakanaka kwe switchgear;

○ The shrinkage yekurapa idiki, kazhinji 1% -2%; iyo mutsara yekuwedzera coefficient zvakare idiki kwazvo, kazhinji 6 × 10 / ℃. Nokudaro, ukuru hwekushandura hwakagadzikana, kushushikana kwemukati kuduku, uye hakuzotseki.

Chokwadi zvakatipoteredza zvine hushamwari green switchgear

● GVG-12 epoxy resin solid insulated yakavharirwa zvakazara switchgear inonyatso kuenderana zvakatipoteredza green switchgear.

○ Iyo epoxy resin pachayo ine zvimiro zvemakemikari yakagadzikana, uye hapana kushanduka uye kupararira kwechero zvinhu zvine chepfu;

○ Iko hakuna nyaya inoshanduka panguva yeotomatiki yekumanikidza gel (APG tekinoroji), hapana kudonha mushure mekunge gel yabatwa, uye hapana kuburitsa gasi panguva yekupora;

○ Iyo switchgear haina SF6 greenhouse gasi inobuda, haina kusvibiswa kwemafuta, uye haina magasi ane muchetura uye zvinhu zvinokuvadza panguva yekushanda;

○ Mushure mekupera kwehupenyu hwesevhisi, epoxy resin inogona kukurumidza kuora kuburikidza nenzira mbiri dzekurapa: kutenderera kwekupisa uye kutenderera kwemakemikari kurapwa, uye inogona kudzokororwa uye kushandiswazve nehunyanzvi hwekubvisa.

○ Zvese zvinoshandiswa mu epoxy resin solid insulated zvakavharirwa zvakazara switchgear zvinhu zvinogadzikiswazve, uye hazvibudise chero mvura yakasvibiswa, ndoda chero gasi rine muchetura. Iyo ndeyechokwadi yezvakatipoteredza yakasvibira switchgear.

Chizvarwa chitsva chezvigadzirwa zvepamusoro
