I-AC contactor isisetshenziswa sokuhlola esiphelele esiphelele, okuhlanganisa izinhlobo ezinhlanu ezilandelayo zokuqukethwe kokuhlola:
a) Ukwethembeka kothintana naye (ukucisha izikhathi ezi-5): Engeza i-voltage elinganiselwe engu-100% kuzo zombili iziphetho zekhoyili yomkhiqizo we-AC contactor, yenza isenzo sokucisha izikhathi ezi-5 (amapharamitha angasethwa ngokuzenzakalelayo) ukuze ubone ukuthi abathintwayo bomkhiqizo bathintwa ngendlela enokwethenjelwa, futhi ingabonisa ngokuqondile isimo sokuhlola sokucisha sabathintwayo besigxobo ngasinye.
b) Ukusetshenziswa kwamandla okudonsa/ukukhipha/okubamba:
i.Isivivinyo se-voltage yokumunca: ngokwenani lokucaciswa kwe-voltage yokulawula, isilawuli siphakamisa i-voltage yokulawula ku-voltage ethile ngesivinini esingaguquki kuze kube yilapho umkhiqizo usudonswa, sirekhoda inani le-voltage ngalesi sikhathi okuyi-voltage yokudonsa, futhi sinquma noma ngabe umkhiqizo uncelwa ngokwethembekile noma cha; abese elungisa i-voltage yokulawula enanini likagesi elilinganiselwe ukuze kulinganiswe amandla asetshenziswa ikhoyili, futhi kuqhathaniswe wonke amanani akalwayo nevelu evamile ukuze kuqinisekiswe ukuthi ifanelekile noma cha;
ii. Ukuhlolwa kokukhishwa kwe-voltage: ngokwenani lokucaciswa kwe-voltage yokulawula, uhlelo kuqala lulayisha u-100% Wethu kukhoyili (inani likagesi lingasethwa), livumele umkhiqizo usebenze izikhathi eziningana (inani lezikhathi lingasethwa), bese linciphisa. i-voltage yokulawula ngesivinini esifanayo kuze kube yilapho umkhiqizo ukhishwa, futhi urekhoda inani le-voltage ngalesi sikhathi njenge-voltage yokukhulula.
c) imingcele yokuxhumana: ikhoyili ayinawo amandla, i-servo motor ishayela ukunyakaza kwe-probe endaweni (ngokuthintana nabakaki abathintekayo), isenzo se-probe ukuze kutholakale indawo yereferensi yebanga elivulekile elinguziro, ukucindezelwa kokuxhumana okuguquguqukayo kuze kube i-static. kanye nokuxhumana othintana naye oguqukayo, ngalesi sikhathi, ibanga lokunyakaza kwemishini ye-probe okungukuthi, ibanga elivulekile lomkhiqizo; ikhoyili 100% Us ukumunca okunamandla, i-servo motor ishayela umshini we-probe uyaqhubeka nokunyakaza ukuze uthintane nobakaki othintana naye oguqukayo, ukuze kutholwe indawo eyiziro yesisekelo esidlulayo Ngemva kokuba ikhoyili engu-100% Us inikezwe amandla futhi imunce, i-servo motor ishayela umshini wokuhlola. ukuqhubeka nokuya ekuthinteni ubakaki othintana naye ogudlukayo ukuze unqume indawo yereferensi enguziro ye-overtravel, bese umkhiqizo ukhishwa ngokucisha ugesi, i-servo motor ihlehla, kanye nebanga eliphakathi kwendawo enguziro nokunqanyulwa koxhumene nabo abahambayo nabamile. kuwukuhamba ngaphezulu; isamba sebanga elivulekile kanye nokuhamba ngaphezulu yingqikithi yohambo. Othintana naye oyinhloko webanga elivulekile eliphezulu nenani elincane liyasuswa ukuze kutholwe inani lokuvumelanisa. Ukuqhathaniswa kwedatha nenani elimisiwe, ukuze kunqunywe ufanelekile noma cha.
d) I-voltage ukumelana: Uma ikhoyili ingenawo amandla, icindezelwa umzuzwana owodwa, 2500VAC (i-voltage 0 ~ 5000V iyalungiseka, ukuvuza kwamanje 0 ~ 100mA kuyalungiseka) ukuhlola amatheminali angenayo naphumayo, isigaba kanye nekhoyili nge izici ze-voltage yekhoyili; ukumuncwa ikhoyili, isigaba sokuhlola nomhlabathi, ikhoyili enomhlabathi enezici ze-voltage eqinile.
Lo mshini ungahambisana nosayizi abahlukene abahlukene be-AC contactors, ungumshini ongabizi kakhulu.
