I-contactor ye-C&J AC, yomsizi wakho wokuphepha.

Isakhiwo somkhiqizo

1, II-contactor ye-ACisebenzisa indlela kagesi kagesi ukushayela isekethe eyinhloko, futhi ukuhlukaniswa nokuhlanganiswa kwamaphoyinti okuxhumana ayinhloko kulawulwa yi-electromagnet kanye nohlelo lokuxhumana oluyinhloko.

2, Iphuzu eliyinhloko lokuxhumana kwe-I-contactor ye-ACisetshenziselwa ukuxhuma nokunqamula ukunikezwa kwamandla e-AC, futhi ingasetshenziswa njengesekethe yokuguqula.

3, Uhlelo lokuxhumana lweI-contactor ye-ACngokuvamile yakhiwa oxhumana nabo ababili abayinhloko kanye noxhumana nabo ababili abasizayo abanamathele ku-bracket.

4, Ikhoyili ye-AC contactor ifakiwe engxenyeni yensimbi, futhi kukhona amashidi okuvikela kanye nama-windings azungeze ikhoyili. Ama-windings ngokuvamile angama-300 ~ 350 m ubude.

5, Uhlelo lokuxhumana lweI-contactor ye-ACYakhiwe ngamadivayisi okucima i-arc, angahlukaniswa ngezinhlobo ezimbili: uhlobo lokuhlukanisa kanye nohlobo lokungahlukanisi. Uhlobo lokuhlukanisa luhlanganisa idivayisi yokucima i-arc yomoya kanye negumbi lokucima i-arc yensimbi, kanti uhlobo lokungahlukanisi luhlanganisa idivayisi yokulondoloza igesi ye-carbon arc noma yokucima i-arc ye-vacuum.

Isimiso sokusebenza

Lapho i-AC contactor inika amandla i-electromagnetic coil, i-electromagnet idonsela i-coil bese i-coil current idlula kwi-load circuit ukuze ikhiqize i-electromagnetic torque. Ngesikhathi esifanayo, ngenxa yokuthi i-iron core ine-magnetic field, amandla e-electromagnetic akhiqizwayo abangela ukuthi i-movable iron core inyakaze futhi imunce i-contactor coil. Lapho i-coil current inyamalala, i-magnetic field iyanyamalala, intwasahlobo ibuyisela i-moving core endaweni yayo yokuqala, futhi i-contactor inqamula i-circuit ngokushesha.

Uma ikhoyili ye-AC contactor ifakwa ugesi, amandla ayo ahlobene nokumelana nomthwalo. Ukumelana okuphezulu kwenza ugesi udlule kancane futhi kudle amandla kagesi amancane. Uma i-AC contactor uma ugesi ukhiqizwa yikhoyili uba mkhulu, ngakho-ke ku-contact eyinhloko ukwakha inani elithile lokushisa.

Ukushisa okukhiqizwayo kusekethe kungokulandelayo:

3, Ukushisa okukhiqizwa yisenzo soxhumana naye oyinhloko

4, Ukushisa okubangelwa ukwanda kwegesi esembozweni;

5, ukushisa okubangelwa ukuhuzuka komshini;

Amapharamitha obuchwepheshe

1, I-voltage elinganisiwe: AC380V noma AC380V, 60Hz.

3, Imvamisa yokusebenza: 20Hz ~ 40Hz.

4, Izinga lokushisa eliphezulu lokusebenza kwekhoyili: – 25 ℃ ~ + 55 ℃.

5. Umthamo wokucima i-arc: ingcindezi ye-arc ekamelweni lokucima i-arc kufanele ikwazi ukuqinisekisa ukuthi isikhathi sokuvutha okukodwa singaphezu kwama-3ms ku-100W, futhi ngokuvamile isebenzisa idivayisi yokucima i-arc engu-30W.

6, Ukwehla kwamandla kagesi kwe-contactor akumele kudlule u-2% noma u-5% wamandla kagesi alinganisiwe.

8, Isikhathi sokuqalisa: ngaphansi noma okulingana no-0.1S (kumanje okulinganiselwe okungaphezu kuka-30A, isikhathi sokuqalisa kufanele sibe ngaphansi kuka-0.045S); kumanje okungaphansi kuka-20A, isikhathi sokuqalisa kufanele sibe ngaphansi kuka-0.25S.

10, Izinga lokushisa eliphansi lokusebenza: ku- – 25 ℃, vumela amahora okusebenza amafushane angu-0 ~ 40 min, amahora okusebenza aphezulu angu-20 min.

Izexwayiso

1. Izinga le-voltage elisetshenziselwa i-AC contactor kumele lihlangabezane ne-voltage ekalwe echazwe ngumkhiqizo.

2. Ngaphambi kokusebenzisa i-AC contactor, hlola ukuthi ukubukeka kwayo konakele yini, ukuthi izingxenye ziphelele yini, nokuthi ama-terminals akhululekile noma aphumile yini.

3. Ezindaweni lapho i-voltage yokunikezwa kwamandla ishintshashintsha kakhulu, i-contactor ye-AC kufanele ifakwe amadivayisi okubuyisela ahambisanayo.

4. Uma i-contactor ye-AC ixhunywe ngentambo, imodeli yetheminali kufanele ihlolwe ngokucophelela, futhi kuthathwe izinyathelo ezihambisanayo uma ukulandelana kwesigaba noma amapharamitha kutholakala ukuthi akuhambisani.

5. Lapho kuhlolwa imikhiqizo emisha, i-AC contactor kufanele ihlole ngokucophelela ukuthi i-voltage yokusebenza ekaliwe, i-current yokusebenza ekaliwe kanye nenani lokusetha ukuvikelwa liyahlangabezana yini nezidingo.

6. Inhlansi, i-arc kanye nokunye ukuphazamiseka okukhulu kwe-electromagnetic kungase kwenzeke lapho ukuxhumana okuyinhloko kwe-AC contactor kuphukile. Ngakho-ke kufanele kuhlolwe njalo uma kwenzeka izimo eziyingozi.
