I-Cjx2–d (lc1-d) series AC contactor (ebizwa ngokuthi i-contactor), esetshenziswa kakhulu kwi-AC 50Hz noma i-60Hz, Uma i-AC voltage ingu-660V (690V), futhi i-voltage yokusebenza ingu-380V ngaphansi kwesigaba sesevisi ye-AC-3, isekethe enomthamo wokusebenza olinganiselwe ku-170a isetshenziselwa isekethe yokuvula nokuvala ibanga elide. Ingahlanganiswa ne-thermal relay ehambisanayo ukwakha i-magnetic starter ukuvikela isekethe ngokulayisha ngokweqile okungenzeka. I-Contactor ifanele ukuqala nokulawula njalo i-AC motor.

I-contactor kanye ne-LC1, LC2, Lp1, LP2, cjx4-d zinomsebenzi ofanayo kanye nemininingwane ehambisanayo, engasetshenziswa ngokulinganayo komunye nomunye. Kungumkhiqizo ofanele kakhulu wokufaka esikhundleni semikhiqizo emidala efana ne-cj0 kanye ne-CJ10.

Nizimo zokusebenza ezivamile kanye nezimo zokufakwa

1. Izinga lokushisa lomoya elizungezile lingu--5c – +40c, kanti isilinganiso sokushisa komoya emahoreni angama-24 asidluli ku-+35c;

2. Ukuphakama: kungabi ngaphezu kwama-2000m;

3. Izimo zomkhathi: izinga lokushisa elihlobene lomkhathi akumele lidlule u-50% ku-+40c, kanti umswakama ohlobene ungaba phezulu ekushiseni okuphansi. Izinga lokushisa eliphansi eliphakathi nendawo lenyanga enemvula kakhulu akumele lidlule u-+25c, kanti isilinganiso esiphezulu somswakama ohlobene wenyanga akumele sidlule u-90%. Futhi cabanga ngokuminyana komkhiqizo ngenxa yokushintsha kwezinga lokushisa;

4. Izinga lokungcola: Ibanga lesi-3;

5. Isigaba sokufakwa: isigaba I;

6. Izimo zokufakwa: ukuthambekela kobuso bokufakwa kanye nendiza eqondile akumele kudlule ama-5°;

7. Ukudlidliza kokushaqeka: umkhiqizo kufanele ufakwe futhi usetshenziswe ezindaweni ezingenakho ukudlidliza okukhulu, ukushaqeka nokudlidliza.

8. Imodi yokufaka: ngaphezu kokufakwa kwezikulufo, i-contactor ingafakwa ne-clamp rail ejwayelekile engu-35mm. Ukusebenza kwe-AC 40-95 kungafakwa nge-clamp rail engu-35 mm noma engu-75mm;

Qaphela: isitimela esingu-75mm kuphela esingasetshenziswa ekusebenzeni kwe-DC 40-95, kanti i-115-170 ifakwe isitimela esikhethekile sokubamba.

Sizici zesakhiwo

1. I-contactor iyavikela, isakhiwo sesenzo sisebenza ngqo, i-contact iyindawo ephindwe kabili, enezici zomthamo omncane, isisindo esincane, ukusetshenziswa kwamandla okuphansi, impilo ende, ukuphepha kanye nokuthembeka;

2. I-contactor ingasetshenziswa njengesiqalo se-magnetic esiguquguqukayo esixhumene ngomshini, isiqalo se-star delta decompression, futhi ingangeza neqembu lokuxhumana elisizayo kanye nekhanda lokulibaziseka komoya ngokuya ngokukhethwa komsebenzisi kanye nenye inhlanganisela yemikhiqizo yochungechunge oluvela kolunye.
