Thuthukisa ubuchwepheshe bokubandlulula bokulandelana kwesigaba esizenzakalelayo, okuvumela ukulandelana kwesigaba segridi yamandla yezigaba ezintathu ukuthi ixhunywe ngokukhululekile ngaphandle kwesidingo sokuhlukanisa ngesandla;
Thuthukisa idizayini yezingxenyekazi zekhompuyutha ngaphezu kwezidingo ezijwayelekile zikazwelonke zokumelana nogesi:
Idizayini esanda kuthuthukiswa yezingxenyekazi zekhompiyutha ihlangabezana nemfuneko yomzuzu ongu-1 we-standstand voltage engu-2500 volts AC, nokuvuza kwamanje okungaphansi kuka-2mA, ngaphansi kakhulu kwezinga likazwelonke lika-30mA;
⑻ Thuthukisa izinga lamanje lempendulo yokulungiswa komshini:
I-Hardware esanda kuthuthukiswa kanye nesofthiwe yokulawula, inciphisa umthamo womshini womkhiqizo ngaphezu kwama-31% futhi ikhuphule yamanje ngama-34%;
Lungiselela ama-fuse:
Lungiselela i-DC kanye nezigaba ezintathu ze-AC fuse, qinisekisa ukuthi ukuvikelwa kwesifunda esifushane kusendaweni, futhi uqinisekise ukusebenza okuphephile kwe-inverter;
⑽ Idivayisi yokuhlunga eyakhelwe ngaphakathi, inqubo egcwele yokuhlunga umsindo, ukuphazamiseka kugridi yamandla yi-1/4 yaleyo yeziguquli zefrikhwensi ezejwayelekile;
⑾ Impendulo eyakhelwe ngaphakathi elungisa kabusha esebenzayo ekupheleni, enganikeza impendulo evuselela amandla kagesi kugridi. I-reactor eyakhelwe ngaphakathi nesihlungi, ingaxhunywa ngokuqondile kugridi yamandla, ngempendulo yamandla esebenza kahle efinyelela ku-97%. Ukonga amandla ngo-20% kuya ku-50% ngaphezu kweziguquli zefrikhwensi evamile, nokulahlekelwa ukushisa okungaphansi kuka-3% wamabhuleki okumelana, kunciphisa imithombo yokushisa, nokuthuthukisa ukuphepha;
12. Impendulo eyakhelwe ngaphakathi yokubuyisela esebenzayo ekupheleni, kusetshenziswa ukulungiswa kwe-IGBT, kunganciphisa u-15% kuya ku-25% womthamo wegridi yamandla uma kuqhathaniswa nokusebenzisa ukulungiswa kwebhuloho lokulungisa imvamisa evamile;
⒀ Impendulo eyakhelwe ngaphakathi elungisayo esebenzayo ekugcineni, isici samandla sifika ku-0.99;
Impendulo eyakhelwe ngaphakathi yokubuyisela esebenzayo ekupheleni, phakathi nokusebenza okulinganiselwe, ukuhlanekezela kwe-THD kwamandla kagesi wegridi kungaphansi kuka-5%, futhi ukuhlanekezela kwe-THD yamanje yegridi kungaphansi kuka-5%, kuhlangabezana nezidingo zekhwalithi yegridi;
Yonke idrayivu eyindilinga, ehambisana ne-magnetic synchronous motor engapheli kanye nezilawuli ze-asynchronous motor;
485 umsebenzi wokuxhumana, osekela iphrothokholi yokuxhumana ejwayelekile ye-485 kumodi ye-RTU;
⒄ Inemisebenzi eminingi yokuvikela efana ne-overcurrent, overload, short circuit, overvoltage, hardware overvoltage, undervoltage, ukulahleka kwesigaba segridi yamandla, amplitude yegridi yamandla, ukushisa ngokweqile, ukufaka amaphutha angaphandle, njll., ukuze kuqinisekiswe ukusebenza kohlelo oluphephile noluthembeke kakhudlwana;
Kulula ukufaka, ukulungisa iphutha, nokusebenza, ngokulungiswa nokugcinwa okulula;
