Ama-contact ahlukaniswe ama-AC contactors (voltage AC) kanye ne-DC contactors (voltage DC), asetshenziswa emandleni, ekusabalaliseni nasezikhathini zikagesi. Ngomqondo obanzi, i-contactor ibhekisela ezintweni zikagesi zezimboni ezisebenzisa ikhoyili yamanje ukuze zikhiqize amandla kazibuthe futhi vala othintana nabo ukuze ulawule umthwalo.
Ku-electroscience, ngoba inganqamula ngokushesha i-ac ne-DC main loop futhi ingavula njalo kanye nokulawula kwamanje okuphezulu (kufika ku-800A) isekethe, evame ukusetshenziswa enjinini njengento yokulawula ingasetshenziswa futhi njengejeneretha yemishini yokulawula yemishini yokulawula. kanye nomthwalo ohlukahlukene wamandla, i-contactor ayikwazi kuphela ukuvula nokusika isifunda, kodwa futhi ibe nomphumela wokuvikela ukukhululwa kwe-voltage ephansi.Umthamo wokulawula i-Contactor mkhulu, ulungele ukusebenza okuvamile nokulawula okukude, ingenye yezingxenye ezibalulekile ohlelweni lokulawula okuzenzakalelayo. .
Kugesi wezimboni, kunamamodeli amaningi okuxhumana, futhi ukusebenza kwamanje kuyahlukahluka ku-5A-1000A, futhi ukusetshenziswa kwayo kusakazeke kakhulu.
Umgomo wosonkontileka uyasebenza
Isimiso sokusebenza se-contactor siwukuthi: lapho ikhoyili ye-contactor inikwa amandla, ikhoyili yamanje izokhiqiza insimu kazibuthe, inkambu kazibuthe yenza umgogodla omile ukhiqize ukumuncwa kwe-electromagnetic ukuheha umgogodla, futhi ishayele isenzo sephuzu le-AC contactor, ngokuvamile kuvale othintana naye. inqanyuliwe, ngokuvamile ivula othintana naye ivaliwe, kokubili kukhona ukuxhumana.Lapho ikhoyili ivaliwe, ukumuncwa kuka-electromagnetic kuyanyamalala, futhi i-armature ikhishwa ngaphansi kwesenzo somthombo wokukhululwa, okwenza othintana naye alulame, ukuthintana okuvame ukuvuleka kuyanqanyulwa, futhi othintana naye ovamise ukuvaleka uyavaleka.Oxhumana nabo be-DC basebenza ngendlela ethi ayifane neshintshi yezinga lokushisa.Indlela yokuhlanganisa izintambo ze-AC
