歐姆龍延時繼電器作業(yè)原理

發(fā)布日期:2022-04-26 點擊率:49 品牌:歐姆龍_Omron


歐姆龍延時繼電器由鐵芯、線圈、銜鐵、觸點簧片等構成的。只需在線圈兩頭加上的電壓,線圈中就會流過的電流,然后發(fā)作電磁效應,銜鐵就會在電磁力招引的效果下打敗回來繃簧的拉力吸向鐵芯,然后股動銜鐵的動觸點與靜觸點(常開觸點)吸合。當線圈斷電后,電磁的吸力也隨之不見,銜鐵就會在繃簧的反效果力回來的,使動觸點與的靜觸點(常閉觸點)吸合。吸合、開釋,然后抵達了在電路中的導通、堵截的意圖。繼電器的“常開、常閉”觸點,來差異:繼電器線圈未通電時處于斷開的靜觸點,稱為“常開觸點”;處于接通的靜觸點稱為“常閉觸點”。
