China T2 20RT fekitari nevagadziri

T2 20RT

Chishandiso chekudzivirira chekuvhiya ndeche T2 AC simba rekuvhiya mudziviriri, iyo yakaiswa

pakati pemagetsi ekupa network nemidziyo yekudhonza, kudzvanya uye kuderedza

overcurrent uye overvoltage inokonzerwa nekukandwa kwemheni kana gidhi remagetsi system,

kuitira kuti uderedze kukuvadza kune zvigadzirwa zvemagetsi.Chigadzirwa chacho chinogadzirwa ne-built-in

Thermal release device uye fuse, fuse inogona kutsiviwa.Inonyanya kushandiswa kudzivirira mheni

yerail transit power system
