ZN73-12 mndandanda m'nyumba ngolo-mtundu mkulu-voteji vacuum dera wosweka ndi m'nyumba switchgear ndi magawo atatu AC 50Hz ndi oveteredwa voteji 12kV.Itha kugwiritsidwa ntchito poyang'anira ndi kuteteza mabizinesi amakampani ndi migodi, malo opangira magetsi, malo ocheperako, ndi zida zamagetsi, ndipo ndiyoyenera m'malo omwe amagwiritsidwa ntchito pafupipafupi.Makina ogwiritsira ntchito amaphatikizidwa ndi thupi lophwanyira dera, ndipo mapangidwewo angagwiritsidwe ntchito ngati choyikapo chokhazikika, kapena akhoza kukhala ndi makina apadera oyendetsa galimoto kuti apange gawo la ngolo yamanja.Gawo lalikulu ladera litha kugwiritsa ntchito mzati wokhazikika wokhazikika kuti uzindikire miniaturization, kudalirika kwakukulu komanso kusamalidwa kwa wophwanya dera.

Kagwiritsidwe Ntchito Bwinobwino

◆ Kutentha kozungulira: osapitirira 40 ℃, osatsika kuposa -10 ℃ (kusungirako ndi zoyendera pa -30 ℃ zimaloledwa).
◆ Kutalika: osapitirira 1000m.(Ngati mulingo ukufunika kuonjezedwa, mulingo woyezetsa wovotera udzawonjezedwa moyenerera)
◆Chinyezi chachibale: chiwerengero cha tsiku ndi tsiku sichiposa 95%, chiwerengero cha tsiku ndi tsiku cha mphamvu ya nthunzi yodzaza ndi MPa, ndipo mwezi uliwonse siposa 1.8 × 10.
◆Kuchuluka kwa chivomerezi: osapitirira 8.
◆ Malo opanda moto, kuphulika, kuipitsidwa kwakukulu, kuwonongeka kwa mankhwala ndi kugwedezeka kwakukulu.
