FN5-12 mtundu wa m'nyumba AC mkulu voteji katundu brek lophimba (Apa amatchedwa katundu yopuma lophimba) maapulo kuti AC 50Hz 12kV netiweki, chifukwa kuswa katundu panopa ndi kutseka yochepa dera panopa. Kusinthana kwapang'onopang'ono kokhala ndi fusesi kumatha kuletsa njira yayifupi yotchingira chitetezo.

Kusinthana kwa katundu kumatha kugwiritsidwa ntchito ndi makina ogwiritsira ntchito amtundu wa CS6-1, ndipo chida ichi chapadera chimagwiritsa ntchito makina ogwiritsira ntchito a CS.

Kugwiritsa ntchito

FN5-12 mtundu wa m'nyumba AC mkulu voteji katundu yopuma lophimba (Pano amatchedwa katundu yopuma lophimba) amagwira ntchito pa AC 50Hz 12kV network, chifukwa kuswa katundu panopa ndi kutseka yochepa dera panopa. Kusinthana kwapang'onopang'ono kokhala ndi fusesi kumatha kuletsa njira yayifupi yotchingira chitetezo.

Kusinthana kwa katundu kumatha kugwiritsidwa ntchito ndi makina ogwiritsira ntchito amtundu wa CS6-1, ndipo mankhwalawa amagwiritsa ntchito CS mwapaderapakamwamakina opangira ntchito.

Mtundu ndi Tanthauzo

Gwiritsani ntchito chilengedwe

a. Kutalika

b. Mpweya wozungulira_rmFre: -25 ~ + 40 ° C, (motorized opaleshoni limagwirira〉-5 ° C);

c. Chinyezi chachibale: pafupifupi tsiku lililonse

d. Mpweya wozungulira wopanda kuipitsidwa koonekeratu, monga mpweya woyaka kapena woyaka, mpweya wamadzi, ndi zina.

e. Popanda kugwedezeka kwamphamvu.
