Umphakeli wedivayisi yempendulo yamandla ukukhumbuza ukuthi isiguquli sefrikhwensi sisenokusebenza okungagculisi ngesikhathi sokusebenza, okuholela ekuphileni kwesevisi esifushanisiwe kanye nezindleko zokulungisa izingxenye zaso.
Ukuhlaziya indawo yohlelo lokusebenza, ikhwalithi yegridi yamandla, ukuthikamezeka kazibuthe, nezinye izici zeziguquli zemvamisa, ezinye izindaba okufanele ziqashelwe kanye neziphakamiso zokuthuthukisa kukholakala ukuthi ziwusizo kuwo wonke umuntu.
indawo yokusebenza
Ekusetshenzisweni okungokoqobo kweziguquli zefrikhwensi, abantu abaningi bazifaka ngqo kumasayithi wezimboni ukuze behlise izindleko. Ngokuvamile kuba nezinkinga ngothuli oluphezulu, izinga lokushisa eliphezulu, nomswakama ophezulu emsebenzini. Kwezinye izinhlelo zokusebenza zemboni, kukhona nezinkinga ngothuli lwensimbi, amagesi abolayo, nokunye. Izinyathelo ezihambelanayo kufanele zithathwe ngokusekelwe esimweni sendawo.
I-1) I-converter ye-frequency kufanele ifakwe ngaphakathi kwekhabhinethi yokulawula.
2) Kungcono ukufaka isiguquli semvamisa phakathi kwekhabhinethi yokulawula; I-converter yefrikhwensi kufanele ifakwe iqonde phezulu, futhi izingxenye ezinkulu ezingase zivimbe i-exhaust kanye nokudla kufanele zigwenywe ukuthi zifakwe ngokuqondile ngenhla nangaphansi.
3) Ibanga elincane phakathi kwamaphethelo angaphezulu naphansi wesiguquli sefrequency kanye nengaphezulu, phansi, ukwahlukanisa, noma izingxenye ezinkulu ezidingekayo zekhabhinethi yokulawula kufanele libe likhulu kuno-300mm.
I-4) Uma abasebenzisi abakhethekile bedinga ukususa ikhibhodi ngesikhathi sokusetshenziswa, imbobo yekhibhodi kuphaneli ye-inverter kufanele ivalwe ngokuqinile nge-tape noma ishintshwe iphaneli yokukhohlisa ukuvimbela inani elikhulu lothuli ukungena ngaphakathi kwe-inverter.
I-5) Amabhodi wesekethe amaningi aphrintiwe kanye nezingxenye zesakhiwo sensimbi ngaphakathi kweziguquli zemvamisa azizange zithole ukwelashwa okukhethekile ukuvimbela umswakama, isikhunta kanye nesikhutha. Uma bechayeka ezindaweni zokusebenza ezinzima isikhathi eside, izingxenye zesakhiwo sensimbi zijwayele ukugqwala. Ngaphansi kokusebenza kwezinga lokushisa eliphezulu, imigoqo yethusi eqhubayo izoba nokugqwala okukhulu, okuzodala ukulimala kwezintambo ezincane zethusi ebhodini lokulawula le-microcomputer kanye nebhodi lamandla lokushayela. Ngakho-ke, ekusetshenzisweni kwegesi eswakeme neyonakeleyo equkethe izindawo, kufanele kube nezidingo eziyisisekelo zomklamo wangaphakathi wesiguquli sefrikhwensi esisetshenzisiwe.
6) Uma usebenzisa i-frequency converter ezindaweni ezinothuli, ikakhulukazi ezindaweni ezinothuli lwensimbi eningi nezinto ezintantayo, ngokuvamile kudingeka ukuthi ikhabethe lokulawula livalwe lilonke futhi liklanywe ngokukhethekile nge-air inlet kanye ne-outlet ukuze kungene umoya; Ingaphezulu lekhabhinethi yokulawula kufanele libe nenetha elivikelayo kanye ne-air outlet yekhava yokuzivikela; Phansi kwekhabhinethi yokulawula kufanele ibe ne-base plate, indawo yokungenisa umoya, nezimbobo zokufaka izintambo, futhi ifakwe inethi engangeni uthuli.
ukuphazamiseka kwe-electromagnetic
Ezinhlelweni zesimanje zokulawula izimboni, i-microcomputer noma ubuchwepheshe bokulawula be-PLC buvame ukusetshenziswa. Enqubweni yokuklama noma ukuguqulwa kwesistimu, kufanele kuqashelwe ukuphazanyiswa kweziguquli zefrikhwensi ebhodini lokulawula le-microcomputer. Ngenxa yokuthi amanye amabhodi okulawula ama-microcomputer aklanyelwe iziguquli ze-frequency awahambisani nezindinganiso zamazwe ngamazwe ze-EMC, kungase kube nokuphazamiseka kokukhipha imisebe ngemva kokusebenzisa isiguquli semvamisa, okuvame ukuholela ekusebenzeni okungavamile kwesistimu yokulawula. Izindlela ezilandelayo zinikeziwe njengereferensi yakho.
1) Ukufaka isihlungi se-EMI ekugcineni kokufaka kwesiguquli sefrikhwensi kungacindezela ngempumelelo ukuphazamiseka okwenziwe kwesiguquli sefrikhwensi kugridi yamandla. Ukufaka okokufaka kwe-AC ne-DC kungathuthukisa isici samandla, kunciphise ukungcoliswa kwe-harmonic, futhi kuzuze imiphumela emihle ebanzi. Kwezinye izimo lapho ibanga eliphakathi kwenjini nesiguquli sefrikhwensi lidlula u-100m, i-bpqjs.com idinga ukungeza i-reactor ephumayo ye-AC ohlangothini lwesiguquli ukuze ixazulule ukuvikelwa kwamanje okuvuzayo okubangelwa amapharamitha wokusabalalisa wentambo ephumayo iye phansi futhi yehlise ukuphazamiseka kwemisebe yangaphandle.
Enye indlela iwukuxhuma amapayipi ensimbi noma izintambo zokuvikela, futhi uxhume ngokuthembekile igobolondo lepayipi lensimbi noma ungqimba oluvikela ikhebula phansi. Ngaphandle kokwengeza ireactor ephumayo ye-AC, ukusebenzisa intambo yepayipi yensimbi noma izintambo ezivikelwe kuzonyusa amandla asabalalisiwe okukhiphayo emhlabathini, okujwayele ukudlula.
2) Ukuvikela ugesi kanye nokuhlukaniswa kokufakwayo kokutholwa kwenzwa ye-analog kanye namasiginali okulawula i-analog. Enqubweni yokuklama yesistimu yokulawula eyakhiwe iziguquli zemvamisa, kunconywa ukuthi ungasebenzisi ukulawula kwe-analog ngangokunokwenzeka, ikakhulukazi uma ibanga lokulawula likhulu kuno-1m futhi lifakwe kuwo wonke amakhabethe okulawula. Ngenxa yokuthi iziguquli zefrikhwensi ngokuvamile zinezilungiselelo eziningi zesivinini futhi zishintsha okokufaka nokukhiphayo, zingahlangabezana nezidingo. Uma ukulawulwa kwe-analogi kudingekile, kunconywa ukusebenzisa izintambo ezivikelekile futhi ufinyelele iphuzu elikude eliphansi ohlangothini lwenzwa noma isiguquli se-frequency. Uma ukuphazamiseka kusenzima, izinyathelo zokuhlukanisa i-DC/DC kumele zisetshenziswe. Amamojula ajwayelekile e-DC/DC angasetshenziswa, noma ukuguqulwa kwe-v/f kungahlukaniswa ngokubona kanye nokufaka imvamisa kungasetshenziswa.
3) Ukufaka izihlungi ze-EMI, ama-inductors emodi evamile, izindandatho kazibuthe ezinemvamisa ephezulu, njll. ekunikezeni amandla okokufaka kwebhodi lokulawula le-microcomputer kungacindezela ngempumelelo ukuphazamiseka okwenziwe. Ukwengeza, ezimeni lapho ukuphazamiseka kwemisebe kubi kakhulu, njengalapho kukhona iziteshi eziyisisekelo ze-GSM noma ze-pager, isembozo sensimbi sensimbi singangezwa ebhodini lokulawula le-microcomputer ukuze livikeleke.
4) Isisekelo esihle. Intambo yaphansi yezinhlelo zokulawula zamanje eziqinile ezifana namamotho kufanele zisekelwe ngokuthembekile ngebhasi ephansi, futhi indawo yokuvikela yebhodi yokulawula yamakhompiyutha amancane kufanele isekelwe ngokuhlukile. Ezimweni ezithile ezinokuphazamiseka okunzima, kunconywa ukuxhuma isendlalelo sokuvikela isikhombimsebenzisi se-I/O endaweni yokulawula yebhodi lokulawula.
Ikhwalithi yegridi yamandla
I-voltage flicker ivame ukwenzeka emithwalweni yomthelela efana nemishini yokushisela, izithando zikagesi ze-arc, izigayo zensimbi, njll; Eshabhubhu, lapho iziguquli eziningi eziguquguqukayo eziguquguqukayo kanye neminye imithwalo ye-capacitive rectifier isebenza, ama-harmonics akhiqizwa yizo adala ukungcoliswa okukhulu kwekhwalithi yegridi yamandla futhi abe nomthelela omkhulu olimazayo kumshini ngokwawo, kusukela ekungakwazini ukusebenza ngokuqhubekayo nangokujwayelekile ukubangela umonakalo kumjikelezo wokufakwayo kwesisetshenziswa. Kungasetshenziswa izindlela ezilandelayo ukuxazulula inkinga.
1) Kunconywa ukuthi abasebenzisi bengeze amadivayisi esinxephezelo samandla asebenzayo asebenzayo ukuze kuthuthukiswe isici samandla nekhwalithi yegridi yamandla lapho bebhekana nemithwalo enomthelela efana nemishini yokushisela, iziko likagesi ze-arc, nezigayo zensimbi.
2) Ezingqungqutheleni lapho kugxilwe khona iziguquli zefrikhwensi, kuyanconywa ukuthi kusetshenziswe ukulungiswa okuphakathi nendawo kanye nokunikezwa kwamandla kagesi webhasi avamile e-DC. Kunconywa ukuthi abasebenzisi basebenzise imodi yokulungiswa kwe-pulse engu-12. Izinzuzo ama-harmonics aphansi nokonga amandla, ikakhulukazi afaneleka ukuqalisa kanye nokubhuleka njalo, lapho i-motor kagesi isebenza kuzo zombili izimo zokukhiqiza ugesi kanye namandla.
3) Ukufaka isihlungi se-LC esingenzi lutho ngasohlangothini lokokufaka lwesiguquli semvamisa kunciphisa ama-harmonic okokufaka, kuthuthukisa isici samandla, sinokuthembela okuphezulu, futhi kuzuza imiphumela emihle.
4) Ukufaka idivayisi ye-PFC esebenzayo ohlangothini lokufakwayo lwesiguquli semvamisa kuveza imiphumela engcono kakhulu, kodwa izindleko ziphakeme kakhulu.
Kusukela ezinkingeni eziphakama ohlelweni lokusebenza olusebenzayo lweziguquli zemvamisa, le ndatshana iphakamisa izixazululo eziqondiwe kanye neziphakamiso zokuthuthukisa umthelela wezinto ezingezinhle kuziguquli zemvamisa ezinhlelweni ezisebenzayo, ezifana nokuphazamiseka kwangaphandle, indawo yokusetshenziswa, nekhwalithi yegridi yamandla. Lezi zixazululo zinganweba ngempumelelo impilo yesevisi yeziguquli zefrikhwensi futhi zibe nenani elithile lereferensi ezinhlelweni ezisebenzayo zobunjiniyela.
Yiqiniso, indlela eyodwa noma ezimbalwa ngokuvamile ziyasetshenziswa.
