CNH-12/630-20 ZVAKAITIKA-HUSHAMWARI GASI AKAFUNGWA RING SWITCHGEAR
Overview
CNH-12/630-20 gasi rine hushamwari rakavharika mhete network switchgear rudzi rutsva rwegirinhi uye inoshamwaridzana nesimbi yakavharirwa switchgear. Yakavharidzirwa nemagasi ane hushamwari hwezvakatipoteredza akadai semhepo yakaoma kana nitrogen, isina / shoma yekubuda kwegasi regreenhouse. Huwandu hwekudzokororwa kwezvinhu mushure mehupenyu hwechigadzirwa hwasvika 90% kana kupfuura, kunze kwekasi, zvimwe zvikamu zvekudzivirira hazvishandise zvakaoma-ku-degrade epoxy resin zvinhu, kunyatsozadzisa chinangwa chekuve girinhi uye kushamwaridzana. Ose ari maviri anopwanya edunhu uye anoremedza switch anotora vacuum arc kudzimisa, iyo ine yakasimba kuchinjika kwezvakatipoteredza, diki saizi, nzvimbo yekuchengetedza, hapana kudiwa kweSF, kuona gasi nekudzivirira, kushanda kwakachengeteka uye kwakavimbika, kuchengetedza-kusina, uye kungwara. Ndiyo kuvandudzwa kweramangwana rering main unit. direction.
CNH-12/630-20 gasi rine hushamwari kwezvakatipoteredza rakavharwa mhete network switchgear inoshandiswa kumagetsi akazara ekugovera magetsi ane voltage ye12kV, matatu-chikamu AC 50Hz, bhazi rimwe chete uye imwe bhazi segmented system, indasitiri uye yevagari tambo ring network uye yekugovera network terminal. mapurojekiti. Nechinangwa chekugamuchira uye kugovera simba remagetsi, rinoshandiswa mukugovera magetsi munzvimbo dzekugara mumaguta, zviteshi zvidiki zvechipiri, zviteshi zvekuchinjisa, mabhokisi ebazi remabhokisi, mabhokisi emhando yezviteshi, maindasitiri nemabhizimusi emigodhi, zvitoro, nhandare dzendege, subways, mhepo. kugadzira magetsi, zvipatara, nenhandare. , njanji, tunnels nedzimwe nzvimbo.
Product Main Features
◆ Zvakaoma zvinoshanda uye zvakabatanidzwa zvigadzirwa
Iyo inflatable shell ye switchgear yakagadzirwa nepamusoro-mhando 2.5mm gobvu simbi isina tsvina kuburikidza nelaser welding kuti ive nechokwadi chekuti bhokisi remhepo rekuisa chisimbiso kuvimbika, yakakwira mechaniki simba uye yakanaka corrosion kuramba. Chiyero chekudzivirira chegomba chinoputika chinosvika IP67: bhokisi remhepo rakagadzirirwa Iyo diaphragm inoputika inogona kudzivirira zvinokuvadza kukuvadza kwevanhu nemichina kana mhepo yemhepo yakanyanyisa; kuisa chisimbiso zvikamu zvose zvinofambisa mubhokisi remhepo hazvigoni kungodzivisa kupesvedzera kwekunze kwezvakatipoteredza zvinhu, asiwo kunatsiridza kuvimbika kwekushanda, zvichiita kuti irege kuchengetedza. (kana kushomeka kugadzirisa) basa, ukuwo uchisangana nezvinodiwa zve miniaturization.
Dunhu guru rinoshandisa musanganiswa we-tatu-position switch (pa + isolation + grounding) uye vacuum interrupter. Ichi chimiro inzira yehunyanzvi yakakura yekumisikidza uye inokodzera ikozvino magetsi emagetsi kushanda uye kugadzirisa zvinodiwa.
◆Yakanaka nharaunda uye isina kusvibiswa
Iyo insulating yepakati yeCNH-12/630-20 yakasarudzika gasi yakavharwa ring network switchgear ndeye zero-level yakaoma mweya (outsourced) kana 99.99% yakachena N2 mukutevedzera GB/T 8979-2008. Kubuda kwegasi hakuzove nemhedzisiro pane yekunze nharaunda uye haidi kuti iitwe. Chero recycling processing.
◆ Flexible yekuwedzera dhizaini
CNH-12/630-20 inoshamwaridzana nemhepo gasi yakavharwa mhete network switchgear iri modular mudhizaini, uye akasiyana mamodule anogona kubatanidzwa kuburikidza neakazvitsaurira mabhara ekubatanidza. Wana akasiyana mayuniti musanganiswa kuti asangane neakaomesesa uye akasiyana emagetsi ekugovera dhizaini zvirongwa munzvimbo dzakasiyana muChina kusvika pamwero mukuru.
◆Perfect mechanical interlocking
Iyo yekushanda pani yeCNH-12 / 630-20 yakatenderedza gasi yakavharwa mhete network switchgear ine yakazara-uchapupu hushanu mechanical interlocking basa. Zvose zvinopindirana mabasa zvakagadzirirwa mukati. Ndapota shandisai maererano nehurongwa hwemirairo yekushanda. Zviri nyore chaizvo kushandisa.
