Imininingwane Yomkhiqizo

Omaka bomkhiqizo

I-FN5-12 uhlobo lwe-AC high voltage load brek switch yasendlini (ngemuva kwalokhu ebizwa ngokuthi i-load break break) ama-apula kunethiwekhi ye-AC 50Hz 12kV, yokuphula umthwalo wamanje kanye nokuvala isekethe yesifunda esifushane. Iswishi yekhefu lokulayisha ene-fuse inganqamula umjikelezo wesifunda esifushane ukuze kuvikelwe ukushintsha.

Iswishi yekhefu lokulayisha ingasetshenziswa ngohlobo lwe-CS6-1 lwendlela yokusebenza yezandla, futhi lo mkhiqizo okhethekile usebenzisa indlela yokusebenza ye-CS manual.

Isicelo

I-FN5-12 yohlobo lwe-AC yasendlini ye-high voltage break switch (ngemuva kwalokhu ebizwa ngokuthi yi-load break switch) isebenza kunethiwekhi ye-AC 50Hz 12kV, yokuphula umthwalo wamanje nokuvala isekethe yesifunda esifushane. Iswishi yekhefu lokulayisha ene-fuse inganqamula umjikelezo wesifunda esifushane ukuze kuvikelwe ukushintsha.

Iswishi yekhefu lokulayisha ingasetshenziswa ngohlobo lwe-CS6-1 lwendlela yokusebenza yezandla, futhi lo mkhiqizo ukhethekile usebenzisa i-CSumlomoindlela yokusebenza ngesandla.

Uhlobo Nencazelo
