Nhanganyaya yeChigadzirwa

♦Muchina wekupwanya dunhu weM7 series unoshandiswa paAC
♦50/60 Hz, voltage yakaganhurirwa 690V, current yakaganhurirwa ku800A power distribution net circuit, inoshandiswa kuparadzira simba uye kudzivirira circuit nemagetsi emagetsi kubva mukuremadzwa, short circuit, under voltage etc. kukuvara kwezvikanganiso. Inogonawo kushandiswa sekudzivirira mota kutanga nekuremadzwa nguva nenguva, short circuit, under voltage. Chigadzirwa chacho chine vhoriyamu diki, high breaking, short arcing, chinogona kuiswa panzvimbo yakatwasuka uye yakatwasuka.
♦Kupisa kwezvakatipoteredza: Pasi pe50℃
♦Kukwira: Pasi pe2000m; Hunhu hwekutsungirira: hunodzivirira hunyoro, hunodzivirira chakuvhuvhu, hunodzivirira mwaranzi Mamiriro ekuisa: nyura pasi pe22.5
♦ Kushandisa nharaunda: inogona kushanda zvakavimbika pakudengenyeka kwengarava, kudengenyeka kwenyika (4g). Hapana chinhu chinoparadza simbi, uye hachifanirwe kukanganisa gasi rinodziisa, pasina njodzi yekuputika kweguruva rinofambisa mhepo.
♦Yakajairika: GB14048.2
