Ibicuruzwa byacu bishya, NVS1-12 urukurikirane rwimbere rwumuvuduko mwinshi wa vacuum yamashanyarazi ikoreshwa mumashanyarazi muri sisitemu ya 12kV, nkigice cyo kugenzura no kurinda ibikoresho byamashanyarazi mubucuruzi bwinganda n’amabuye y'agaciro, inganda n’amashanyarazi. Bitewe ninyungu zidasanzwe za vacuum yamashanyarazi, irakwiriye cyane cyane kubikorwa kenshi bisaba ko akazi gakorwa neza, cyangwa ahantu umuyoboro mugari wacitse inshuro nyinshi. Umuzenguruko wumuzunguruko ukoresha igishushanyo mbonera cyimikorere yimikorere hamwe numubiri wumuzingi. Byombi nuburyo bwimbere ninyuma, hamwe nibikorwa byizewe byo guhuza. Inzitizi zumuzunguruko zirashobora gukoreshwa nkigice gihamye cyo kwishyiriraho. Irashobora kandi kuba ifite ikamyo ya chassis mubice byikiganza.
Ibipimo byibicuruzwa
GB / T1984-2014 Umuvuduko mwinshi AC Umuzunguruko
JB / T3855-2008 3.6-40.5kV murugo AC Umuvuduko mwinshi wa vacuum yamashanyarazi
DL / T403-2000 12kV-40.5kV yumubyigano mwinshi wa vacuum umuzunguruko utumiza ibintu bya tekiniki
IEC62271-100: 2008 Umuvuduko mwinshi wo guhinduranya no kugenzura igice 100: AC-yamashanyarazi
Ibidukikije
Ubushyuhe bwibidukikije: -15 C ~ + 40C
O Ubushuhe bwibidukikije: Ikigereranyo cya buri munsi ugereranije nubushyuhe
Impuzandengo ya buri munsi yumuvuduko wumuyaga
O Uburebure ≤ 1000m;
O ubukana bwa nyamugigima
O Ahantu ho kwishyiriraho: Ikibanza ntigomba kugira akaga ko gutwarwa n’amazi, kwanduza cyane, kwangirika kwimiti no kunyeganyega neza.
