Umhlinzeki weyunithi yokubhuleka uyakukhumbuza ukuthi ukuze uqinisekise ukusebenza okuphephile nokuzinzile kwesiguquli sefrikhwensi, kubaluleke kakhulu ukuhlangabezana nezidingo ezivumelekile zendawo yokusebenza zesiguquli sefrikhwensi. Kafushane, ungavumeli indawo yokusebenza yesiguquli semvamisa yeqe izinga lokushisa elivumelekile, futhi unake ukusebenza komoya wekhabhinethi yokuguqula imvamisa. Uma izinga lokushisa le-ambient lesiguquli se-frequency liphezulu kakhulu, lizonciphisa ukufakwa kukagesi futhi lidle izingxenye zensimbi. Ukunciphisa umswakama kufanele kucatshangelwe ukuvimbela ukuminyanisa kwesiguquli samaza. Uma usebenzisa isiguquli semvamisa ngaphansi kwezimo zokusebenza eziphephile, amaphuzu alandelayo kufanele abhekwe kahle:
1. Isiguquli sefrikhwensi kufanele sisekelwe ngokuthembekile ukuze kuqinisekiswe ukusebenza okuphephile futhi sicindeze ngempumelelo ukuphazamiseka kozibuthe kagesi.
2. Iziguquli zefrikhwensi azifanele ukwenza ukuhlolwa kwe-voltage ukumelana nokuhlolwa kokumelana nokushisa. Lapho ukwenza, imitha yokumelana nokufakwa kwe-500V kufanele isetshenziselwe ukulinganisa, futhi inani lokuhlola ukuzamazama kufanele lincishiswe ngangokunokwenzeka. Ngaphambi kokufakwa kwe-insulation, wonke amandla amakhulu angaphandle kanye namasekhethi okulawula kufanele anqanyulwe futhi isifunda esikhulu kufanele sibe sifushane; I-insulation yomhlabathi kufanele kuqinisekiswe ukuthi ingaphezu kwama-megohms angu-5.
3. Uma ulawula i-motor nge-converter ye-frequency, kuyadingeka ukuqinisekisa ukuthi imoto inezimo ezinhle zokungenisa umoya, futhi umoya wangaphandle kanye nezinyathelo zokupholisa kufanele zithathwe uma kunesidingo.
4. Uma usebenzisa i-frequency converter enamamotho amaningi, ngaphezu kokuqinisekisa ukuthi inani lamanje lama-motor lingaphansi kwesilinganiso samanje se-frequency converter, kuyadingeka futhi ukubala umthelela wokuqala wamanje wemoto okungenani eyodwa ukuze ugweme ukukhubeka ngokweqile kwesiguquli semvamisa.
5. Amadivayisi esinxephezelo se-Capacitor akufanele axhunywe ohlangothini oluphumayo lwesiguquli sefrikhwensi ukuvimbela ukukhubeka kokuvikela okudlulele kanye nokulimala kusiguquli samaza.
6. Ukusebenza nokuma kwe-motor eshayelwa isiguquli se-frequency akukwazi ukusetshenziswa ngokuqondile kusetshenziswa ama-breaker-voltage circuit breaker noma izixhumi ze-AC. Kufanele isetshenziswe ngamatheminali okulawula isiguquli sefrikhwensi, ngaphandle kwalokho ingabangela isiguquli sefrikhwensi singakwazi ukulawula futhi sibangele izingozi.
7. Gwema ukushayela izinjini ezinezidrayivu eziguquguqukayo ezingahambisani nomthamo wazo. Umthamo omncane wemoto uzothinta ukuphuma kwe-torque esebenzayo, kanti umthamo omkhulu uzokwandisa umthamo we-harmonic.
8. Uma i-motor eqhutshwayo ine-brake, i-converter ye-frequency kufanele isebenze kwimodi yokumisa yamahhala, futhi isignali yesenzo se-brake kufanele ikhishwe ngemuva kokuba isiguquli semvamisa sithumele umyalo wokumisa.
9. Uma usebenzisa isiguquli sefrikhwensi ukushayela amamotho angaqhumisi, ngenxa yokuntuleka kokusebenza okuvikela ukuqhuma, isiguquli sefrikhwensi kufanele sibekwe ngaphandle kwezindawo eziyingozi.
10. Uma isiguquli semvamisa sisetshenziswa ukushayela isinciphisi segiya, ububanzi bokusetshenziswa kwaso bukhawulwa indlela yokugcoba yezingxenye ezijikelezayo zegiya. Uma ugcoba ngamafutha okugcoba, akukho mingcele ngaphakathi kwebanga eliphansi lejubane; Ebangeni lesivinini esiphezulu ngaphezu kwejubane elilinganiselwe, kungase kube nesimo sokungatholakali kwamafutha okugcoba okwanele, ngakho-ke, isivinini esiphezulu esivumelekile kufanele sicatshangelwe.
11. Ukunaka okukhethekile kufanele kukhokhwe ekufundeni ngokucophelela imanuwali yomsebenzisi ngaphambi kokusebenzisa isiguquli sefrikhwensi. Amandla amakhulu okufaka nawokukhiphayo wesiguquli sefrikhwensi awakwazi ukuhlehliswa, futhi i-"COM" ne-"GND" ayikwazi ukuxutshwa. Ukunaka okukhethekile kufanele kukhokhwe: Izihlungi ze-RFI akufanele zisetshenziswe kumagridi wamandla angenasisekelo angathathi hlangothi (amasistimu we-IT, amagridi kagesi antantayo), ngaphandle kwalokho ukunikezwa kwamandla kungase kufinyezeke phansi nge-capacitor yesihlungi, engase ibangele ingozi noma umonakalo ku-converter frequency.
12. Ngesikhathi sokusebenza kwesivivinyo, kufanele siqaliswe ngaphandle komthwalo, bese kuba nomthwalo omncane, futhi ekugcineni ngomthwalo ogcwele.
13. Ngesikhathi sokusebenza kwe-frequency converter, kungenzeka ukuthi uhlole izimo zokusebenza ngaphandle kwemishini nganoma yikuphi ukungahambi kahle, futhi uhlole imingcele yokusebenza ye-converter frequency ngokusebenzisa iphaneli yokusebenza ukuze kutholakale ngokushesha izinkinga nge-converter frequency kanye ne-motor.
14. I-converter ye-frequency kufanele ihlanzwe futhi ifakwe uthuli njalo ukuze igcine ukuhlanzeka kwayo kwangaphakathi kanye nemigudu yomoya ebushelelezi.
15. Gcina imvelo ezungeze isiguquli sefrikhwensi ihlanzekile futhi yomile, futhi ungabeki izinto ezingahlobene eduze nesiguquli sefrikhwensi.
16. Ngemva kokufaka nokugcina i-converter ye-frequency, hlola ngokucophelela izikulufu ezilahlekile namakhanda ezintambo ukuze uvimbele izinto ezincane zensimbi ekuweleni ku-converter ye-frequency futhi zibangele amaphutha wesekethe yangaphakathi yesifunda.
