An AC contactoryog ib qho khoom siv hluav taws xob qis uas siv rau kev txuas thiab txiav cov AC circuits tseem ceeb ntawm qhov deb. Nws siv dav hauv kev tswj lub cev muaj zog, kev faib hluav taws xob, kev lag luam automation, thiab kev tsim cov tshuab hluav taws xob. Nws lub luag haujlwm tseem ceeb yog ua tiav kev pib thiab nres kev tswj hwm ntawm cov khoom siv hluav taws xob los ntawm kev rub cov kev sib cuag los ntawm electromagnetic coils, thiab nws kuj muaj peev xwm siv ua ke nrog cov txheej txheem tiv thaiv overload. Ac contactors feem ntau siv rau hauv cov twj tso kua dej, kiv cua, cua txias, elevators, cov khoom siv tsim khoom, lub txee pib lub cev muaj zog thiab cov txheej txheem tswj teeb pom kev zoo, uas tuaj yeem txhim kho kev nyab xeeb thiab qib automation ntawm kev tswj hwm circuit.

Hauv kev siv tiag tiag, cov AC contactors raug xaiv raws li lawv qhov ntsuas tam sim no, lub zog hluav taws xob, tus lej ntawm cov ncej thiab qhov chaw siv. Piv txwv li, cov khoom siv hauv tsev me me lossis cov khoom siv lag luam me me feem ntau siv cov lus qhia ntawm 9A txog 32A, thaum cov khoom siv hauv Hoobkas loj siv cov contactors muaj zog siab nrog lub peev xwm ntau dua 65A. Cov hom lag luam feem ntau suav nrog Schneider Electric, Siemens, ABB thiab hom lag luam hauv tsev Chint, thiab lwm yam.

Hais txog tus nqi, AC contactors sib txawv heev vim yog cov lus qhia thiab hom: tus nqi ua lag luam ntawm cov khoom me me 9A txog 18A yog kwv yees li 50 txog 150 yuan ib daim, cov khoom nruab nrab 32A txog 65A yog kwv yees li 150 txog 500 yuan ib daim, thiab cov khoom muaj zog siab 100A thiab siab dua feem ntau yog 500 txog 2,000 yuan lossis siab dua. Cov hom lag luam txawv teb chaws feem ntau kim dua li cov hauv tsev, tab sis lawv muaj qee qhov zoo hauv kev ruaj khov, lub neej ntev thiab kev ntseeg siab. Yog li ntawd, hauv cov haujlwm engineering, kev xaiv tsim nyog yuav tsum tau ua ua ke nrog lub peev xwm thauj khoom, ib puag ncig siv thiab peev nyiaj.
