Abahlinzeki beyunithi yamabhuleki bakukhumbuza ukuthi iziguquli zefrikhwensi ziya ngokuya ziduma emisebenzini yansuku zonke yokulawulwa kwezimboni, futhi amayunithi amabhuleki adlala indima ebalulekile ekusetshenzisweni kwama-frequency converters.
1. Iyunithi yokubhuleka kusiguquli sefrikhwensi isetshenziselwa ukushisa amandla kagesi;
2. Uma i-asynchronous motor isebenza esimweni sokubhuleka sokukhiqiza amandla, amandla kagesi aguqulwa kusukela kumandla omshini wesistimu aqoqana engxenyeni ye-DC ye-frequency converter, futhi i-voltage yengxenye ye-DC izokhuphuka, ngakho-ke kufanele ishiswe;
3. Uma i-resistor yokubhuleka isha, kungenzeka ukuthi injini ilahlekelwa ukubhuleka noma isiguquli sefrikhwensi singu-overvoltage;
4. Uma ama-asynchronous motors esebenza ngobuningi bamandla, angashintsha ngokukhululekile phakathi kokuphehla ugesi namandla, ngokulawulwa kwesivinini esiguquguqukayo, okuvimbela umzila wempendulo yamandla wokukhiqiza amandla emoto kanye nokubhuleka;
5. Okusho ukuthi, ngaphandle kwesiguquli semvamisa, amandla akhiqizwa amandla okukhiqiza amandla kanye ne-braking azophendula ngokuzenzakalelayo kugridi, okonga kakhulu amandla! 1. Wonke amamotho, okuhlanganisa amajeneretha, amamotho, nama-transformer, ayabuyiseleka emuva; 2. Ijeneretha ixhunywe kugridi yamandla futhi ingasebenza ngogesi; 3. Izinjini zikagesi zingaphehla ugesi futhi zisebenze kugridi yamandla; 4. Ucabanga ukuthi kuyamangaza, akumangalisi, abantu abaningi abawazi lo mgomo! 1. Imvamisa yokusebenza kwezinjini ezweni lethu ngu-50HZ; 2. Imvamisa yokusebenza kwezinjini emazweni angaphandle ngu-60Hz; 3. Ngokwezibalo zabanye abantu, imvamisa yokusebenza kwezinjini ezweni lakithi iphansi ngo-10Hz, ngakho-ke ukusebenzisa ama-motor avela ezweni lakithi kungawonga ugesi???!!! 4. Inhloso yesiguquli sefrikhwensi ukuklama nokwenza isilawuli sesivinini samamotho asynchronous; 5. Ukusebenzisa i-frequency converter ukusheshisa ama-asynchronous motors, njengoba ukusebenza kahle kwesiguquli se-frequency kungaphansi kwama-80%, ukusebenza kahle kwesistimu kuzokwehla ngo-20%, okuholela ekusetshenzisweni kwamandla okwandayo kunokonga amandla;
6. Ukuze kuhlangatshezwane nezidingo zenqubo, i-asynchronous motor variable frequency regulation iza ngezindleko zokuncipha kokusebenza kahle;
