Iinkcukacha zeMveliso

Iithegi zeMveliso

FN5-12 uhlobo lwangaphakathi AC high voltage umthwalo brek iswitshi (Apha ekubhekiselwa kuyo njengomthwalo ikhefu switch) iiapile ukuya AC 50Hz 12kV womnatha, ngenxa yokwaphula umthwalo lwangoku kunye nokuvala isiphaluka elifutshane yangoku. Umthwalo wekhefu lokutshintsha kunye ne-fuse unokunqumla isiphaluka esifutshane sangoku sokukhusela ukutshintshwa.

Ukutshintshela ikhefu umthwalo ingasetyenziswa CS6-1 uhlobo manual yokusebenza indlela, kwaye le mveliso ekhethekileyo isebenzisa CS manual yokusebenza indlela.

Isicelo

I-FN5-12 uhlobo lwangaphakathi lwe-AC yombane ophezulu wokutshintsha ikhefu lombane (Apha ekubhekiselwa kulo njengokutshintsha kwekhefu lomthwalo) lusebenza kuthungelwano lwe-AC 50Hz 12kV, ngokophula umthwalo wangoku kunye nokuvala isiphaluka esifutshane sangoku. Ukutshintshela ikhefu lomthwalo kunye ne-fuse kunokunqumla i-short circuit current yokukhusela ukutshintshwa.

Ukutshintshela ikhefu umthwalo ingasetyenziswa CS6-1 uhlobo manual yokusebenza indlela, kwaye le mveliso ekhethekileyo isebenzisa CSumlomoindlela yokusebenza ngesandla.

Uhlobo kunye nentsingiselo

Sebenzisa okusingqongileyo

a. Ukuphakama

b. Umoya we-ambient_rmFre: -25 ~ + 40 ° C, (imotho yokusebenza indlela〉-5 ° C);

c. Ukufuma okuhambelanayo: umyinge wemihla ngemihla

d. Umoya we-Ambient ngaphandle kongcoliseko olucacileyo, njengerhasi edlayo okanye enokutsha, umphunga wamanzi, njl.

e. Ngaphandle kongcangcazelo olunamandla.
