Isixhumi se-AC

Imingcele elinganiselwe ye-contactor inqunywa ngokuyinhloko ngokuya nge-voltage, yamanje, amandla, imvamisa kanye nohlelo lokusebenza lwemishini eshajiwe.
(1) I-voltage yekhoyili ye-contactor ngokuvamile ikhethwa ngokuvumelana ne-voltage elinganiselwe yolayini wokulawula. Uma kucatshangelwa ukuphepha komugqa wokulawula, kuvame ukukhethwa ngokuya nge-voltage ephansi, engenza umugqa ube lula futhi wenze lula i-wiring.
(2) Ukukhethwa kwamanje okukaliwe kwesixhumi se-AC kufanele kucatshangelwe uhlobo lomthwalo, indawo yokusetshenziswa kanye nesikhathi sokusebenza esiqhubekayo. Isilinganiso samanje se-contactor sibhekisela kumthamo omkhulu ovunyelwe we-contactor ngaphansi kokusebenza kwesikhathi eside, nobude be-8 h, futhi ifakwe ebhodini lokulawula elivulekile. Uma isimo sokupholisa singesihle, isilinganiso samanje se-contactor sikhethwa ngo-110% ~ 120% wesilinganiso samanje somthwalo. Kumamotho asebenza isikhathi eside, ngenxa yokuthi ifilimu ye-oxide ebusweni bomuntu othintana naye ayinalo ithuba lokusulwa, ukumelana nokuxhumana kuyanda, futhi ukushisa kokuxhumana kudlula izinga lokushisa elivumelekile. Ekukhetheni kwangempela, isilinganiso samanje se-contactor singancishiswa ngo-30%.
(3) Imvamisa yokusebenza komthwalo nesimo sokusebenza sinomthelela omkhulu ekukhethweni komthamo we-AC contactor. Uma umthamo wokusebenza womthwalo udlula imvamisa yokusebenza elinganiselwe, amandla okuxhumana othintana naye azokhuliswa ngokufanelekile. Ngemithwalo evame ukuqala futhi enqanyuliwe, umthamo wokuxhumana we-contactor kufanele ukhuliswe ngokufanele ukuze kuncishiswe ukugqwala kokuxhumana futhi kunwetshwe impilo yesevisi.
2. Ukuhlaziywa kwephutha okuvamile nokugcinwa kwe-AC contactor ene-voltage ephansi
Izixhumi ze-AC zingaphuka njalo phakathi nomsebenzi futhi zingagqoka othintana nabo ngesikhathi sokusetshenziswa. Ngesikhathi esifanayo, ngezinye izikhathi ukusetshenziswa okungalungile, noma ukusetshenziswa endaweni enzima kakhulu, kuzonciphisa ukuphila koxhumana naye, okubangela ukwehluleka, ngakho-ke, ekusetshenzisweni, kodwa futhi ukukhetha ngokuvumelana nesimo sangempela, futhi ekusetshenzisweni kufanele. zigcinwe ngesikhathi, ukugwema ukulahlekelwa okukhulu ngemva kokwehluleka. Ngokuvamile, amaphutha avamile othintana nabo be-AC amaphutha othintana nabo, amaphutha ekhoyili namanye amaphutha emishini kagesi.
