I-C&J AC contactor, ukuze uthole ukuphepha kwakho.

Isakhiwo somkhiqizo

1, IIsixhumi se-ACithatha indlela kagesi ukuze ishayele isekethe eyinhloko, futhi ukuhlukaniswa nokuhlanganiswa kwamaphuzu amakhulu okuxhumana kulawulwa yi-electromagnetic kanye nesistimu yokuxhumana enkulu.

2. Indawo yokuxhumana eyinhloko ye-Isixhumi se-ACisetshenziselwa ukuxhuma nokunqamula ugesi we-AC, futhi ingasetshenziswa njengesekhethi yokuguqula.

3. Uhlelo lokuxhumana lweIsixhumi se-ACngokuvamile yakhiwa othintana nabo abakhulu ababili kanye noxhumana nabo ababili abasizayo abagxilwe kubakaki.

4, Ikhoyili ye-AC contactor ifakwe kumongo wensimbi, futhi kukhona amashidi avikelayo namawindi azungeze ikhoyili.Ama-windings ngokuvamile angu-300 ~ 350 m ubude.

5. Uhlelo lokuxhumana lweIsixhumi se-ACyakhiwe ngezinto zokucisha i-arc, ezingahle zihlukaniswe zibe izinhlobo ezimbili: uhlobo lokuzihlukanisa kanye nohlobo olungahlukanisi.Uhlobo lokuhlukanisa luhlanganisa idivayisi yokucima i-arc yokufaka umoya kanye negumbi lokucisha insimbi ye-dielectric arc, kuyilapho uhlobo olungahlukanisi luhlanganisa igesi ye-carbon arc egcina igesi noma idivayisi yokucima i-arc ye-vacuum.

Isimiso sokusebenza

Lapho isixhumi se-AC sinika amandla ikhoyili kazibuthe kagesi, uzibuthe kagesi uheha ikhoyili futhi ikhoyili yamanje idlula kumjikelezo wokulayisha ukuze ikhiqize itorque kagesi.Ngesikhathi esifanayo, ngenxa yokuthi i-iron core inomkhakha kazibuthe, amandla kazibuthe akhiqizwayo abangela ukuba umgogodla wensimbi onyakazayo unyakaze futhi umunce ikhoyili ye-contactor.Lapho ikhoyili yamanje inyamalala, inkambu kazibuthe iyanyamalala, intwasahlobo ibuyisela umgogodla onyakazayo endaweni yawo yasekuqaleni, futhi i-contactor inqamula ngokushesha isekethe.

Lapho ikhoyili ye-AC contactor ifakwe ugesi, amandla ayo ahlobene nokumelana nomthwalo.Ukumelana okuphezulu kwenza i-current idlule kancane futhi isebenzise amandla kagesi amancane.Lapho contactor AC lapho zamanje ezikhiqizwe ikhoyili emikhulu, ngakho ku-contact main ukwakha inani elithile lokushisa.

Ukushisa okukhiqizwa kusekethe kungokulandelayo:

3, Ukushisa okukhiqizwa yisenzo sothintana naye oyinhloko

4, Ukushisa okukhiqizwa ukunwetshwa kwegesi esembozweni;

5, ukushisa okukhiqizwa ukuhuzuka komshini;

Imingcele yezobuchwepheshe

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

3, Imvamisa yokusebenza: 20Hz ~ 40Hz.

4, Izinga lokushisa eliphakeme kakhulu lekhoyili: – 25 ℃ ~ + 55 ℃.

I-5, Umthamo wokucisha we-arc: ingcindezi ye-arc egumbini lokucisha i-arc izokwazi ukuqinisekisa ukuthi isikhathi sokuthungela okukodwa singaphezu kwama-3ms ku-100W, futhi ngokuvamile yamukele idivayisi yokucima i-arc engu-30W.

I-6, Ukwehla kwe-voltage ye-contactor akufanele kudlule u-2% noma u-5% we-voltage elinganisiwe.

8, Isikhathi sokuqalisa: esingaphansi noma esilingana no-0.1S (okwamanje okulinganiselwe okungaphezu kuka-30A, isikhathi sokuqalisa sizoba ngaphansi kuka-0.045S);okwamanje okungaphansi kuka-20A, isikhathi sokuqalisa sizoba ngaphansi kuka-0.25S.

10, Izinga lokushisa elincane lokusebenza: at - 25 ℃, vumela amahora okusebenza amafushane we-0 ~ 40 min, amahora okusebenza aphezulu angama-20 min.

Izixwayiso

1. Izinga le-voltage elisetshenziselwa isixhumi se-AC kufanele lihlangabezane ne-voltage elinganiselwe eshiwo umkhiqizo.

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

3. Ezindaweni lapho i-voltage yokuphakelwa kwamandla ishintshashintsha kakhulu, isixhumi se-AC sizohlonyiswa ngamadivayisi ahambisanayo esinxephezelo.

4. Uma isixhumi se-AC sinezintambo, imodeli yetheminali izobhekwa ngokucophelela, futhi izinyathelo ezihambisanayo zizothathwa uma ukulandelana kwesigaba noma amapharamitha atholakala engahambisani.

5. Lapho ihlola imikhiqizo emisha, isixhumi se-AC kufanele sihlole ngokucophelela ukuthi i-voltage elinganiselwe yokusebenza, isilinganiso samanje sokusebenza kanye nevelu yesilungiselelo sokuvikela siyahlangabezana yini nezimfuneko.

6. Inhlansi, i-arc nokunye ukuphazamiseka okunamandla kazibuthe kagesi kungase kwenzeke lapho othintana naye omkhulu we-AC contactor ephukile.Ngakho-ke kufanele zihlolwe njalo uma kunezimo eziyingozi.
