皮爾茲安全繼電器的工作原理主要基于電磁原理,它由鐵芯、線圈、銜鐵、觸點(diǎn)簧片等組成。
當(dāng)繼電器線圈通電時(shí),線圈中會產(chǎn)生磁場,從而在銜鐵中產(chǎn)生電磁力,這個(gè)力大于返回彈簧的拉力,導(dǎo)致銜鐵被吸引向鐵芯,進(jìn)而帶動(dòng)銜鐵的動(dòng)觸點(diǎn)與靜觸點(diǎn)(常開觸點(diǎn))接觸,形成閉合電路,實(shí)現(xiàn)電路的導(dǎo)通。當(dāng)線圈斷電后,電磁力消失,銜鐵會在彈簧的反作用力下返回原來位置,使動(dòng)觸點(diǎn)與原來的靜觸點(diǎn)(常閉觸點(diǎn))斷開,從而切斷電路。這種吸合與釋放的動(dòng)作,使得繼電器能夠在電路中實(shí)現(xiàn)導(dǎo)通與切斷的功能。
此外,皮爾茲安全繼電器還包含一個(gè)內(nèi)部電氣和機(jī)械控制系統(tǒng),當(dāng)輸入電路出現(xiàn)異常(如短路或過載)時(shí),繼電器的保護(hù)元件會迅速切斷電源,使輸出觸點(diǎn)打開,從而保護(hù)負(fù)載和操作人員的安全。
