I-C&J AC contactor, yomncedisi wakho wokhuseleko.

Ulwakhiwo lwemveliso

1, IIsixhobo soqhagamshelwano lwe-ACisebenzisa indlela ye-electromagnetic ukuqhuba isekethe ephambili, kwaye ukwahlukana kunye nokudibanisa iindawo eziphambili zoqhagamshelwano kulawulwa yi-electromagnet kunye nenkqubo ephambili yoqhagamshelwano.

2, Indawo ephambili yokunxibelelanaIsixhobo soqhagamshelwano lwe-ACisetyenziselwa ukudibanisa nokuqhawula umbane we-AC, kwaye ingasetyenziswa njengesekethe yokuguqula.

3, Inkqubo yoqhagamshelwanoIsixhobo soqhagamshelwano lwe-ACngokubanzi yenziwa zii-contacts ezimbini eziphambili kunye nee-contacts ezimbini ezincedisayo ezinamathele kwi-bracket.

4, Ikhoyili ye-AC contactor ifakwe kwisiseko sentsimbi, kwaye kukho amaphepha okukhusela kunye nee-windings ezijikeleze ikhoyili. Ii-windings ngokubanzi zinobude obuyi-300 ~ 350 m.

5, Inkqubo yoqhagamshelwanoIsixhobo soqhagamshelwano lwe-ACyenziwe zizixhobo zokucima i-arc, ezinokwahlulwahlulwa zibe ziintlobo ezimbini: uhlobo lokwahlukanisa kunye nohlobo olungahlukanisiyo. Uhlobo lokwahlukanisa luquka isixhobo sokucima i-arc somoya kunye negumbi lokucima i-arc yesinyithi, ngelixa uhlobo olungahlukanisiyo luquka isixhobo sokugcina igesi ye-carbon arc okanye isixhobo sokucima i-arc ye-vacuum.

Umgaqo wokusebenza

Xa i-AC contactor inika amandla i-electromagnetic coil, i-electromagnet itsala i-coil kwaye i-coil current idlula kwi-load circuit ukuze ivelise i-electromagnetic torque. Kwangaxeshanye, ngenxa yokuba i-iron core ine-magnetic field, amandla e-electromagnetic aveliswayo abangela ukuba i-movable iron core ihambe kwaye ifunxe i-contactor coil. Xa i-coil current iphela, i-magnetic field iyaphela, i-spring ibuyisela i-moving core kwindawo yayo yokuqala, kwaye i-contactor iqhawula i-circuit ngoko nangoko.

Xa ikhoyili ye-AC contactor ifakelwe umbane, amandla ayo anxulumene nokumelana nomthwalo. Ukumelana okuphezulu kwenza ukuba umsinga udlule kancinci kwaye kudle amandla ombane amancinci. Xa i-AC contactor xa umsinga uveliswa yi-coil inkulu, ngoko ke kumsinga oyintloko ukwenza ubushushu obuthile.

Ubushushu obuveliswa kwisekethe bulandelayo:

3, Ubushushu obuveliswa sisenzo soqhagamshelwano oluphambili

4, Ubushushu obuveliswa kukwanda kwegesi kwisigqubuthelo;

5, ubushushu obuveliswa kukukhuhlana koomatshini;

Iiparameter zobugcisa

1, I-voltage elinganisiweyo: AC380V okanye AC380V, 60Hz.

3, Ukusebenza rhoqo: 20Hz ~ 40Hz.

4, Ubushushu obuphezulu bokusebenza kwekhoyili: – 25 ℃ ~ + 55 ℃.

5, Umthamo wokucima i-arc: uxinzelelo lwe-arc kwigumbi lokucima i-arc luya kukwazi ukuqinisekisa ukuba ixesha lokutshaya elinye lingaphezulu kwe-3ms kwi-100W, kwaye ngokubanzi lusebenzisa isixhobo sokucima i-arc se-30W.

6, Ukwehla kombane we-contactor akumele kudlule i-2% okanye i-5% yombane olinganisiweyo.

8, ixesha lokuqalisa: ngaphantsi okanye ilingana ne-0.1S (kwi-current elinganisiweyo engaphezulu kwe-30A, ixesha lokuqalisa kufuneka libe ngaphantsi kwe-0.045S); kwi-current engaphantsi kwe-20A, ixesha lokuqalisa kufuneka libe ngaphantsi kwe-0.25S.

10, Ubuncinane bobushushu bokusebenza: kwi -25 ℃, vumela iiyure zokusebenza ezimfutshane ze-0 ~ 40 min, iiyure zokusebenza eziphezulu ze-20 min.

Izilumkiso

1. Inqanaba le-voltage elisetyenziselwa i-AC contactor kufuneka lihlangabezane ne-voltage elinganisiweyo echazwe yimveliso.

2. Ngaphambi kokusebenzisa i-AC contactor, jonga ukuba inkangeleko yayo yonakele na, nokuba iindawo zigqityiwe na, nokuba iiterminals zikhululekile okanye zikhutshiwe.

3. Kwiindawo apho i-voltage yombane itshintshatshintsha kakhulu, i-AC contactor kufuneka ixhotyiswe ngezixhobo zokuhlawula ezifanelekileyo.

4. Xa i-AC contactor ixhunyaniswe ngentambo, imodeli yesiphelo kufuneka ijongwe ngononophelo, kwaye kuthathwe amanyathelo ahambelanayo ukuba ulandelelwano lwesigaba okanye iiparameter zifunyenwe zingangqinelani.

5. Xa kuvavanywa iimveliso ezintsha, i-AC contactor kufuneka ijonge ngononophelo ukuba i-voltage yokusebenza elinganisiweyo, i-current yokusebenza elinganisiweyo kunye nexabiso lokuseta ukhuseleko ziyahlangabezana neemfuno.

6. I-spark, i-arc kunye nolunye uphazamiseko olunamandla lwe-electromagnetic lunokwenzeka xa uqhagamshelwano oluphambili lwe-AC contactor luphukile. Ngoko ke kufuneka zihlolwe rhoqo xa kukho iimeko eziyingozi.
