Iinkcukacha zeMveliso

Iithegi zeMveliso

I-PGS-630A ipali exhonywe kwipali yokutshintsha ikhefu isetyenziselwa ukwaphula amandla ombane alinganisiweyo 12/24/40.5kV, i-630A yangoku, i-50/60Hz inkqubo yokuhambisa amandla, ukuvala umthwalo wangoku kunye nomthwalo wangoku wenkqubo yamandla, inokwahlula ngokuzenzekelayo amacandelo okulandelela unikezelo lwamandla apho iziphene zenzeka. Ukutshintshela kuhambelana nesilawuli se-elektroniki esineteknoloji yakutshanje. Ukutshintsha kunendlela yokusebenza, imotor, ikude. Umlawuli we-elektroniki uya kufakwa ngaphakathi kwebhokisi yensimbi engenasici, ngoko ingasetyenziselwa kwiimeko ezahlukeneyo zemozulu. Ngaphandle koko, imodem yocingo / engenacingo efakwe ngaphakathi kwebhokisi yolawulo inokufikelela ekubekweni kweliso okude kunye nokulawula. Kulula kwaye kulula ukufakela iswitshi kwipali, kwaye oko kunokunciphisa iindleko zokuphumeza.

Iimeko zokusingqongileyo

♦ Ubushushu bomoya:-40℃~+50℃;

♦ Ukufuma okuhambelanayo: 110%

♦ Ukuphakama ≤3000m.

♦ Uxinzelelo lomoya ≤700pa (ilingana nesantya somoya 34m/ｓ).

♦ Ukuqina kwe-Seismic: i-8 degree.

♦ Indawo yofakelo: Akukho ntlekele yomlilo, ingozi yogqabhuko-dubulo, ukonakala kweekhemikhali kunye neendawo zokungcangcazela rhoqo.

♦ Ibakala longcoliseko: Ⅲ iklasi, Ⅳiklasi.

Uhlobo lweenkcazelo

Iintlobo ze-MPP
