Overview
YN28-12 armored inobviswa AC simbi-yakavharirwa switchgear.Inokodzera matatu-phase AC simba system ine rated voltage ye12kV uye yakatemerwa frequency ye50Hz.Inoshandiswa kugamuchira uye kugovera simba remagetsi uye kutonga, kudzivirira uye kutarisa masekete.
Zviyero zvinoenderana:
GB3906-2006 "3.6 ~ 40.5kV AC simbi-yakavharirwa switchgear uye midziyo yekudzora" GB11022-89 "General tekinoroji mamiriro epamusoro-voltage switchgear" IEC298 (1990) "Rated voltage pamusoro pe1kV uye 50kV uye pazasi AC simbi-yakavharirwa switchgear uye controlgear midziyo" DL404 -97 "Technical Conditions yeOdha Indoor AC Yakakwira Voltage Switchgear"
Muenzaniso Zvinoreva
Mabasa uye Zvimiro
Iyo switchgear yakagadzirirwa zvinoenderana neyakavharirwa simbi-yakavharirwa switchgear muGB3906-91.Yese inoumbwa nezvikamu zviviri: iyo kabati muviri uye yepakati-yakaiswa inobviswa chikamu (kureva ngoro yemaoko).Iyo cabinet yakakamurwa kuita makamuri mana akapatsanurwa, iyo yakavharirwa nhanho yekudzivirira ndeye IP4X, uye nhanho pakati peimwe neimwe kamuri uye redunhu rekutyora musuwo wekamuri ndeye IP2X kana yakavhurwa.Iyo ine pamusoro pekupinda mukati uye mitsara yekubuda, tambo yekupinza uye yekubuda mitsara uye zvimwe zvirongwa zvinoshanda, izvo zvinogona kurongeka uye kusanganiswa kuita seti yakakwana yemagetsi ekugovera system zvishandiso.Iyo switchgear inogona kuiswa, yakagadziriswa uye yakachengetedzwa kubva kumberi, saka inogona kuva kumashure-kumashure, yakarongedzwa-kaviri uye yakaiswa pamadziro, iyo inovandudza kuchengetedzwa, kushanduka uye tsoka yeiyo switchgear.
Mamiriro ekushandisa akajairika
◆ Ambient air tembiricha: tembiricha yepamusoro +40 ℃.Minimum tembiricha -15 ℃.
◆ Humidity humidity: zuva nezuva avhareji hunyoro hunyoro: ≤95%;zuva nezuva avhareji yemvura vapor pressure haipfuure 2.2KPa;pamwedzi avhareji hama humidity: ≤90%;pamwedzi avhareji mvura mhute pressure haipfuure 1.8KPa;
◆ Altitude: pasi pe1000m.
◆ Kudengenyeka kwepasi: kwete kudarika 8 degrees.
◆ Mhepo yakapoteredza haifaniri kuve pachena yakasvibiswa negasi rinopisa kana rinopisa, mhute yemvura, nezvimwewo.
◆Hapana nzvimbo inodedera ine chisimba.
◆Kana yakashandiswa pasi pezvakajairwa mamiriro anotsanangurwa muGB3906, zviri kumushandisi uye kambani kutaurirana.
