finder功率繼電器觸點(diǎn)的動(dòng)作過(guò)程可以分為觸點(diǎn)閉合和觸點(diǎn)斷開(kāi)兩部分，即繼電器的吸合和釋放過(guò)程。它們以一定的頻率循環(huán)切換，形成觸點(diǎn)開(kāi)關(guān)現(xiàn)象。在觸點(diǎn)閉合和觸點(diǎn)斷開(kāi)的過(guò)程中，會(huì)出現(xiàn)許多特殊的物理現(xiàn)象和化學(xué)現(xiàn)象，比如觸點(diǎn)電阻、觸點(diǎn)抖動(dòng)和電弧等。 觸點(diǎn)閉合時(shí)的動(dòng)作原理 當(dāng)繼電器的動(dòng)觸點(diǎn)和靜觸點(diǎn)相互接觸的時(shí)候，觸點(diǎn)就會(huì)彈回，即不受控制地間歇打開(kāi)以及關(guān)閉。此時(shí)電流產(chǎn)生的電弧和焦耳熱很大地影響了finder功率繼電器的打開(kāi)和關(guān)閉的能力。 相關(guān)關(guān)系： 當(dāng)觸點(diǎn)斷開(kāi)，負(fù)

finder功率繼電器是指當(dāng)輸入量(或激勵(lì)量)滿足一定確定的準(zhǔn)星形時(shí)，可以在一個(gè)或多個(gè)電器輸出電路中產(chǎn)生躍變作用的一種元件。它可以用于中性點(diǎn)徑直接地系統(tǒng)，作為零序電流保護(hù)的總趨勢(shì)元件。 finder功率繼電器的工作原理是在finder功率繼電器的圓環(huán)上添加兩次所需的電壓或電流時(shí)，圓環(huán)產(chǎn)生的磁通穿過(guò)由分極、磁軛、銜鐵和磁路辦事氣隙組成的磁路，銜鐵在磁場(chǎng)的表達(dá)下被吸向分極極面，使前進(jìn)觸點(diǎn)的常閉觸點(diǎn)斷開(kāi)，常開(kāi)觸點(diǎn)閉合。當(dāng)圓環(huán)兩端的電壓或電流達(dá)不到一定值，機(jī)械反作用力超過(guò)電磁吸引力時(shí)，銜鐵回到初始狀
