Abafowunelwa be-AC

I. Ukukhethwa kwabafowunelwa be-AC
Iiparamitha ezilinganisiweyo ze-contactor zimiselwa ngokukodwa ngokwe-voltage, yangoku, amandla, i-frequency kunye nenkqubo yokusebenza yezixhobo ezihlawuliswayo.
(1) I-coil voltage ye-contactor ikhethwa ngokubanzi ngokwe-voltage elinganisiweyo yomgca wokulawula.Ukuqwalasela ukhuseleko lomgca wokulawula, ngokuqhelekileyo ukhethwa ngokuhambelana nombane ophantsi, onokwenza lula umgca kwaye uququzelele i-wiring.
(2) Ukukhethwa kombane olinganisiweyo we-AC contactor kufuneka kuthathelwe ingqalelo uhlobo lomthwalo, indawo yokusetyenziswa kunye nexesha eliqhubekayo lokusebenza.Umlinganiselo olinganisiweyo we-contactor ubhekisela kwisigxina esiphezulu esivumelekileyo soqhagamshelwano phantsi kokusebenza kwexesha elide, kunye nobude be-8 h, kwaye ifakwe kwibhodi yokulawula evulekileyo.Ukuba imeko yokupholisa ihlwempuzekileyo, umbane olinganisiweyo we-contactor ukhethwa ngu-110% ~ 120% yesantya esilinganisiweyo somthwalo.Kwiimoto ezisebenza ixesha elide, ngenxa yokuba ifilimu ye-oxide ebusweni boqhagamshelwano ayinalo ithuba lokucocwa, ukuchasana koqhagamshelwano kwandisa, kwaye ubushushu boqhagamshelwano budlula ukunyuka kweqondo lokushisa elivumelekileyo.Kukhetho lwangempela, i-current rated of the contactor ingancitshiswa nge-30%.
(3) I-frequency yokusebenza komthwalo kunye nemeko yokusebenza inempembelelo enkulu ekukhethweni komthamo we-AC contactor.Xa umthamo wokusebenza womthwalo udlula i-frequency yokusebenza elinganisiweyo, umthamo woqhagamshelwano womnxeba uya kwandiswa ngokufanelekileyo.Ukuqala rhoqo kunye nemithwalo enqanyuliweyo, umthamo woqhagamshelwano we-contactor kufuneka unyuswe ngokufanelekileyo ukunciphisa ukubola koqhagamshelwano kunye nokwandisa ubomi benkonzo.
2. Uhlalutyo oluqhelekileyo lwempazamo kunye nokugcinwa kwe-AC ye-AC contactor
Abafowunelwa be-AC banokuphuka rhoqo ngexesha lomsebenzi kwaye banokunxiba abafowunelwa be-contact ngexesha lokusetyenziswa.Kwangaxeshanye, ngamanye amaxesha ukusetyenziswa okungafanelekanga, okanye ukusetyenziswa kwindawo enzima ngokwentelekiso, kuya kunciphisa ubomi bonxibelelwano, kubangele ukungaphumeleli, ke ngoko, ekusebenziseni, kodwa nokukhetha ngokwemeko eyiyo, kwaye ekusetyenzisweni kufuneka. zigcinwe ngexesha, ukuphepha ilahleko enkulu emva kokusilela.Ngokubanzi, iimpazamo eziqhelekileyo zabafowunelwa be-AC ziziphene zoqhagamshelwano, iimpazamo zekhoyili kunye nezinye iimpazamo zomatshini wombane.
(1) Qhagamshelana ne-welding enyibilikayo
Kwinkqubo yokufunxa uqhagamshelwano oluguquguqukayo kunye ne-static, ukuchasana koqhagamshelwano lomphezulu kukhulu kakhulu, kubangela indawo yoqhagamshelwano emva kokunyibilika kunye ne-welding kunye, ayinakophulwa, ebizwa ngokuba yi-contact melt welding.Le meko ngokuqhelekileyo kwenzeka frequency yokusebenza iphezulu kakhulu okanye ukusetyenziswa overload, umthwalo ekupheleni isiphaluka elifutshane, uxinzelelo spring zoqhagamshelwano lincinane kakhulu, ukumelana jam ngoomatshini, njl. Xa ezi meko zisenzeka, zinokususwa ngokubeka indawo contactor efanelekileyo okanye ukunciphisa i umthwalo, ukuphelisa iimpazamo zesiphaluka ezimfutshane, ukubuyisela umfowunelwa, ukulungelelanisa uxinzelelo lomphezulu woqhagamshelwano, kunye nokubangela i-jam factor.
(2) Amanqaku oqhagamshelwano ukutshisa okanye ukutshisa
Kuthetha ukuba ukushisa kwe-calorific yoqhagamshelwano olusebenzayo ludlula ubushushu obulinganisiweyo.Le meko idla ngokubangelwa zezi meko zilandelayo: uxinzelelo lwasentwasahlobo luncinci kakhulu, ukudibana neoyile, ubushushu bendalo buphezulu kakhulu, unxibelelwano lwenkqubo yokusebenza ixesha elide, ukusebenza kwangoku kukhulu kakhulu, okukhokelela kunxibelelwano. ukuqhawula umthamo awonelanga.Inokusombululwa ngokulungelelanisa uxinzelelo lwentwasahlobo yoqhagamshelwano, ukucoca indawo yoqhagamshelwano, i-contactor, kunye nokutshintsha umnxibelelwano kunye nomthamo omkhulu.
(3) Ikhoyili ishushu kakhulu kwaye itshiswa
Imeko eqhelekileyo ibangelwa i-coil interturn short circuit, okanye xa ukusetyenziswa kweeparameters kunye nokusetyenziswa kwangempela kweeparameters azihambelani, ezifana ne-voltage elinganisiweyo kunye neyona ndlela yombane yokusebenza ayidibanisi.Kukwakho nokubakho kwentsimbi engundoqo ibhloko yomatshini, kule meko, ukususa impazamo yebhloko.
(4) Umnxibelelanisi akavaliwe emva kokunika amandla
Ngokubanzi, unokujonga ukuba ikhoyili yaphukile kuqala.Kwimeko yokungaphumeleli kwamandla, i-multimeter ingasetyenziselwa ukulinganisa ukuba ikhoyili ingaphakathi koluhlu oluchaziweyo.
(5) Ukunqongophala kokufunxa
Xa i-voltage yonikezelo lwamandla iphantsi kakhulu okanye iguquguquka kakhulu, okanye i-voltage elinganisiweyo ye-coil ngokwayo inkulu kuneyona ndlela yokulawula i-voltage yesiphaluka, ukufunxa kwe-contactor kuya kunganelanga.I-voltage inokulungelelaniswa ukuze ihambelane ne-voltage yangempela elinganisiweyo ye-contactor.Kwangaxeshanye, ukuba indawo eshukumayo ye-contactor ivaliwe, ibangela ukuba undoqo uthambe, nto leyo enokukhokelela ekufunxeni okwaneleyo, inxalenye ebambekileyo inokususwa kwaye ilungelelanise indawo yondoqo.Ukongeza, i-reaction force spring inkulu kakhulu, kodwa inokukhokelela ekufunxeni okungonelanga, imfuneko yokuhlengahlengisa amandla entwasahlobo.
(6) Abafowunelwa abanakusetwa kwakhona
Okokuqala, unokujonga ukuba abafowunelwa abamileyo kunye nabamileyo badityaniswe kunye.Ukuba oku kuyenzeka, ngokubanzi ungachacha ngokubuyisela abafowunelwa, kwaye ujonge nokuba kukho into ebambekayo kwiindawo ezishukumayo.
