Iimpawu eziphambili zombane oHleliweyo

Umbane oqhelekileyo onokucwangciswa unokuvelisa i-voltage ephezulu yamandla ombane kunye nemiqondiso yangoku ezinzileyo ene-amplitude ehlengahlengiswayo, i-frequency kunye ne-phase angle. Isetyenziselwa ikakhulu ukuvavanya nokuqinisekisa i-current, i-voltage, i-phase, i-frequency, kunye ne-power meters; ingasetyenziswa nakwii-standard power meters ukuqinisekisa nokuqinisekisa impazamo esisiseko, ukuqhekeka, kunye novakalelo lwee-power meters (ii-watt-hour meters).

Umbane wovavanyo olawulwa yinkqubo usebenzisa ulawulo lwekhompyutha encinci, ubuchwepheshe obuphambili, ulawulo olupheleleyo lwenkqubo, ukusebenza kwezitshixo ezipheleleyo, ubungakanani obuncinci, ubunzima obulula, kunye nokulungeleyo ukuwuphatha. Ungasetyenziswa kwilebhu okanye kwindawo yokusebenza. Ngumthombo wamandla osemgangathweni ochanekileyo, owenziwe yi-DSP esekwe kwi-1.2GMAC, i-FPGA enkulu, i-DA ekhawulezayo nechanekileyo, kunye ne-amplifier yamandla ephezulu.

Zisetyenziswa kakhulu kwamanye amashishini okanye kwiiyunithi zamandla ombane ezifuna imithombo yesignali esemgangathweni echanekileyo. Zineemfuno eziphezulu kakhulu kwimithombo yamandla. Kuya kusetyenziswa izixhobo zamandla ezilawulwa yinkqubo. Olu hlobo lwezixhobo zamandla luya kuba ngokuchanekileyo ngakumbi ekulinganiseni nasekuhloleni.

Iimpawu eziphambili zezi:

1. Ukubonelela ngemiqondiso ye-sinusoidal ye-sinusoidal ezinzileyo, ehlala ihleli, etshintsha-tshintshayo, eguquguqukayo-frequency ephezulu yamandla oshishino;

2. Uvavanyo kunye nokuqinisekiswa kwe-voltage, current, phase, frequency kunye ne-power meter zingenziwa;

3. Ingasetyenziswa ngeemitha zeeyure ze-watt eziqhelekileyo ukuqinisekisa nokuqinisekisa impazamo esisiseko, ukurhubuluza nokuqala kwemitha yeeyure ze-watt (imitha yeeyure ze-watt);

4. Ulawulo lwe-microcomputer kunye nolawulo lwenkqubo luqaphela ukuqala okuthambileyo kunye nokuma okuthambileyo, ngaloo ndlela kuthintelwe impembelelo kunye nomonakalo kwisixhobo;

5. Xa kukho iimpazamo zokusebenza, ezifana ne-voltage short circuit, i-current open circuit okanye i-wiring error, i-output inokumiswa ngokuzenzekelayo kwaye i-alamu iya kukubuza ukuba ulungise;

6. Isixhobo sisebenza ngesitshixo, zonke izicwangciso zesitshixo zicwangcisiwe, kwaye isoftware ivaliwe, ngoko ke ukusebenza ngokungacwangciswanga akuyi konakala;

7. Ukwenziwa kwe-digital waveform ecocekileyo, ukuguquguquka kwe-digital amplitude ecocekileyo, utshintsho lwesigaba, kunye nokuguqulwa kwe-frequency. Ichanekile, izinzile kwaye ithembekile;

8. I-amplifier yamandla isebenzisa izixhobo ze-VMOS ezinamandla aphezulu ezingenisiweyo ezithembekileyo kakhulu;

9. Sebenzisa ulawulo lwekhompyutha encinci enetshiphu enye, isekethe edibeneyo enkulu kakhulu kunye nezinye iiteknoloji, ubungakanani obuncinci, ubunzima obulula, kunye nomxholo ophezulu wobugcisa.
