Abahlinzeki bedivayisi yempendulo yamandla bakukhumbuza ukuthi ekukhiqizweni kwezimboni, amakhabethe okulawula ukuguqulwa kwemvamisa (amakhabethe okulawula ugesi ashintshashintsha njalo/amakhabethe okulawula ugesi) angasetshenziswa kakhulu kumishini ehlukahlukene ye-voltage ephakathi nendawo njengamaphampu, amafeni, ama-compressor komoya, izigayo eziginqikayo, imishini yokubumba umjovo, amabhande okuthutha, njll. kwezensimbi, amakhemikhali, i-petroleum, i-petroleum, i-industrial supply, izinsiza zamanzi, izinsiza zamanzi, i-ministries, kanye nemishini yokwakha.
Isiguquli semvamisa siyingxenye enkulu yekhabhinethi yokulawula imvamisa eguquguqukayo nebhokisi lokulawula imvamisa, futhi namanye amakhabethe okulawula we-PLC ayayisebenzisa. Isiguquli sefrikhwensi saziwa nangokuthi idrayivu eguquguqukayo noma isilawuli sedrayivu. I-frequency converter iwuhlobo lwesistimu ye-speed drive eguquguqukayo esebenza ubuchwepheshe be-variable frequency drive ukuze uguqule imvamisa kanye nobukhulu be-voltage esebenzayo yemoto ye-AC, ukuze kulawulwe kahle isivinini kanye ne-torque ye-AC motor. Uhlobo oluvame kakhulu isiguquli se-AC/AC esinokufakwayo nokuphumayo kwe-AC.
Ekhabetheni lokulawula ukuguqulwa kwemvamisa kanye nebhokisi lokulawula ukuguqulwa kwemvamisa, liyingxenye ebalulekile. Nakuba kungumuntu omncane, kunendima enkulu. Ngakho-ke iyini imisebenzi nezici zayo kukhabhinethi yokulawula? Ake sibheke!
1. Izici zokuguqula imvamisa
(1) Ukwamukela izindlela zokulawula ze-PWM eziningi, i-waveform ye-voltage ephumayo iseduze ne-sine wave.
(2) Ukuphindwaphindwa kwamasekhethi okulungisa kuholela kuma-pulses angafika kwangu-36, isici samandla aphezulu, nama-harmonics okokufaka aphansi.
(3) Idizayini eyimojuli, ukwakheka okuhlangene, ukugcinwa okulula, nokushintshashintsha komkhiqizo okuthuthukisiwe.
(4) Ukukhipha okuqondile kwe-high-voltage ngaphandle kwesidingo se-transformer ephumayo.
(5) Okukhiphayo kwe-dv/dt okuphansi kakhulu, asikho isidingo sanoma yiluphi uhlobo lwesihlungi.
(6) Ukusetshenziswa kobuchwepheshe bokuxhumana be-fiber optic kwenze ngcono ikhono lokulwa nokuphazamiseka nokuthembeka komkhiqizo.
(7) Isifunda se-bypass esizenzakalelayo seyunithi yamandla singafeza umsebenzi wokungavimbi umshini uma kwenzeka kuba namaphutha.
2. Umsebenzi wokuguqula imvamisa
1. Umkhawulo we-torque olungisekayo
2. Ukulawulwa kokusebenza okubuyisela emuva
3. Yehlisa izingxenye ezijikelezayo zemishini
4. Umsebenzi wokusheshisa olawulekayo
5. Lawula amandla okuqala enjini
