Ikhabhinethi yokulawula ye-AC contactor PLC njengenhlanganisela yokuvikela

I-AC Contactor (I-Alternating Current Contactor), iyonke, Intuthuko eqhubekayo yokuma nokusebenza, Kodwa ngokusebenza okufanayo, Ikakhulukazi yakhiwa uhlelo lwe-electromagnetic, isistimu yokuxhumana, idivayisi yokucima i-arc kanye nezingxenye ezisizayo, Uhlelo lwe-electromagnetic lwakhiwa ikakhulukazi ikhoyili. , insimbi (i-static iron core) kanye ne-armature (i-iron core ehambayo) izingxenye ezintathu;Isistimu yokuxhumana ihlukaniswe yaba iphuzu, ukuxhumana komugqa kanye nokuxhumana okungaphezulu;Idivayisi yokucisha i-arc ngokuvamile isebenzisa ukucisha kwe-arc kagesi okuqhekeka kabili, ukucisha i-arc ehlangene longitudinal kanye nesango le-arc lokucisha izindlela ezintathu zokucisha i-arc, Ukuqeda i-arc kagesi ekhiqizwa othintana nabo ashukumisayo nabaqinile ngesikhathi sokuhlukanisa nokuvala, Oxhumana nabo abanomthamo ngenhla. 10A babe nezinto zokucisha i-arc;Izingxenye ezisizayo ikakhulukazi zifaka intwasahlobo yokusabela, isiphethu sebhafa, intwasahlobo yengcindezi yokuxhumana, indlela yokudlulisa, ikholomu yesisekelo netheminali nokunye.
Isimiso sokusebenza se-AC contactor siwukuthi lapho ikhoyili ye-contactor inikwa amandla, ikhoyili yamanje izokhiqiza insimu kazibuthe, futhi inkambu kazibuthe ekhiqizwe yenza umgogodla omile ukhiqize ukumuncwa kwe-electromagnetic ukuheha umgogodla, futhi iqhubele isenzo sephoyinti lokuxhumana le-AC, othintana naye ovamise ukuvaleka uyanqanyulwa, ukuxhumana okuvamise ukuvuleka kuvaliwe, okubili kuyaxhunyaniswa.Lapho ikhoyili icishiwe, ukumuncwa kwe-electromagnetic kuyanyamalala, bese i-armature ikhishwa ngaphansi kwesenzo se-spring yokukhulula ukwenza othintana naye alulame, ukuxhumana okuvame ukuvuleka kuyaphuka. , futhi othintana naye ovame ukuvaleka uyavala.Kuwukusebenzisa amandla kazibuthe kagesi kanye nokunwebeka kwentwasahlobo ukubambisana, ukufeza ukuxhumana nokwehlukana.
Ngokwezidingo zamakhasimende, ukukhiqizwa kwamakhabethe okulawula amakhasimende, kungakhathaliseki ukuthi kukhethwe othintana nabo zokuxhumana noma ezinye izingxenye, bazozama konke okusemandleni abo ukuze amakhasimende akhethe futhi ahlangabezane nezidingo zekhwalithi ephezulu yasekhaya nezangaphandle.
Umgomo wokukhetha wesixhumi se-AC:
(1) Izinga le-voltage kufanele lifane nomthwalo, futhi uhlobo lwe-contactor kufanele lufanele umthwalo.
(2) Umsinga obaliwe womthwalo uzohambisana nezinga lomthamo we-contactor, okungukuthi, amandla amanje ababalwayo angaphansi noma alingana nesilinganiso sokusebenza samanje sesixhumi. yamanje yomthwalo, futhi i-breaking current inkulu kunokusebenza komthwalo.Umthamo obaliwe womthwalo kufanele ucabangele indawo yokusebenza yangempela.Ngomthwalo onesikhathi eside sokuqala, ukuphakama okuphezulu kwesigamu sehora akukwazi ukudlula ukushisa okuvunyelwene ngakho.
(3) Hlola ukuzinza okuguquguqukayo nokushisayo kwesikhathi esifushane.Umjikelezo omfushane wesigaba sesithathu solayini ngeke udlule amandla aguquguqukayo avumelekile futhi ashisayo oxhumene naye.Lapho umjikelezo wesifunda esifushane unqanyulwa yi-contactor, amandla okuphuka kwe-contactor nawo azoqinisekiswa.
(4) I-voltage elinganiselwe, yamanje, inani namandla amanje okuthintana naye okuyisizayo kwekhoyili yokumunca yesixhumi esithintayo izohlangabezana nezidingo zezintambo zesekethe yokulawula. inani le-voltage yokusebenza, i-contactor idinga ukusebenza ku-85~110% yenani le-voltage elinganiselwe.Uma ulayini umude kakhulu, ikhoyili ye-contactor ingase ingabonisi umyalo wokuvala ngenxa yokwehla kwamandla kagesi aphezulu;umyalelo wohambo ungase ungasebenzi ne-high line capacitor.
(5) Hlola imvamisa yokusebenza evumelekile kothintana naye ngokwezikhathi zokusebenza.Uma ifrikhwensi yokusebenza idlula inani elishiwo, umthamo okaliwe kufanele uphindwe kabili.
(6) Amapharamitha wesici sokuvikela isifunda esifushane kufanele akhethwe kanye nemingcele ye-contactor.Sicela ubhekisele kumanuwali wesampula, ngokuvamile anikeza ithebula elimeshayo lezixhumi namafuse.
