KYN28A-12 Overview
Mudziyo uyu ndewemukati mesimbi nhumbi dzokurwa nadzo dzine switchgear inodhirowa (pano inoreva se switchgear.3.6-12kilovolt nhanho nhatu AC 50Hz bhawa rimwe chete rebhazi uye imwe bhazi bar subsection system's yakakwana yekugovera magetsi michina inoshandiswa musimba remagetsi, diki nepakati-saizi jenareta. kufambisa kwemagetsi, indasitiri uye bhizinesi remigodhi simba rekugovera pamwe neyemagetsi indasitiri system yechipiri yemagetsi inoshandura substation yemagetsi kutora-pamusoro, kufambisa kwemagetsi uye yakakura-yakanyanya kudzvinyirira mota kutanga uye zvichingodaro.Chinangwa ndechekudzora, kudzivirira uye kutarisa.Iyi switch midziyo irikusvika pachiyero cheIEC298, GB3906 uye inogona kudzivirira kuchaja kusunda nekudhonza breaker, kubva pakuvhura nekuvhara breaker, kubva pakuvharirwa nemagetsi nekukanganisa, kubva kuvhu kuchinjika kuvharira breaker, kubva pakuvhura switch yekuvharisa kana iine. Haagone kushandisa chete neVSI vacuum circuit-breaker, asi neABB Corporation's VD4 vacuum circuit.-breaker.Zvechokwadi imhando yemagetsi ekugovera midziyo ine kushanda kwepamusoro.
KYN28A-12 Shandisa zvakatipoteredza mamiriro
1. Mamiriro ezvinhu
◆ Kutenderera kwemhepo tembiricha: -10C ~ + 40 ℃
◆Altitude:1000M
◆ Hunyoro hwemamiriro ekunze: Huwandu hwemazuva ese hunyoro hwehunyoro hausi hwakakwira kupfuura 95%, mwedzi wega wega hunyoro hunyoro haupfuuri 90%
Kudengenyeka: Kusimba hakupfuuri 8 degree.
◆ Mhepo yakapoteredza isina gasi rinopisa kana kuti rinopisa kana mhute yemvura.
◆Pasina tsvina yakawanda uye kudengenyeka kunotyisa nguva dzose, pasi pemamiriro ezvinhu akaoma, simba rinosangana nemhando yekutanga inoda.
2.special working conditions Kana ichishandiswa kupfuura zvakajairwa mamiriro ezvakatipoteredza anotarwa muGB3906, mushandisi anofanira kubvunza nezvekugadzira.
KYN28A-12 Chimiro Nhanganyaya
Iyo switch yemidziyo yakagadzirwa zvinoenderana neGB3906-91 simbi yekushongedza chisimbiso switch michina.Muviri wekugadzirisa unoumbwa nemuviri wekhabhineti uye zvikamu zvekudhirowa (zvinonzi handcart) yakaiswa pakati.Ona charter 1. Kabati inoparadzanisa mumakamuri mana akaparadzana, giredhi rekudzivirira rekunze rekuvhara ndiro IP4X, apo imwe neimwe kamuri duku uye mhepo inoputika inovhurwa, giredhi rekudzivirira ndiro IP2X.Iyo inogona kumisa iyo inopinza, yekubuda mutsetse, tambo yekupinza, yekubuda mutsetse uye imwe hurongwa hwebasa.Mushure mekurongwa uye kusanganiswa, inogona kuve yega yega yemhando yehurongwa hwemagetsi ekugovera michina.Iyi switch yemidziyo inogona kuiswa uye kuchengetedzwa kubva kumberi, saka inogona kuumba iyo mbiri kurongeka kumashure uye kuisirwa kumadziro, ichivandudza chengetedzo yemudziyo wekuchinja uye kuchinjika uye kushandisa zvizere nzvimbo yekugara.
