摘 要:針對(duì)以往分勵(lì)脫扣器控制電路存在的不足,設(shè)計(jì)了一種簡(jiǎn)單的且符合國標(biāo)要求的新的交直流分勵(lì)脫扣器控制電路,介紹了各模塊功能,并給出了最低成本控制電路圖。仿真實(shí)驗(yàn)表明,該控制電路僅用14個(gè)元件,完成了可預(yù)置電磁鐵動(dòng)作時(shí)間,可長(zhǎng)通電的分勵(lì)脫扣控制。
關(guān)鍵詞:分勵(lì)脫扣器;控制電路;最低成本;長(zhǎng)通電

Abstract: Aiming at insufficiency of control circuit for shunt release, this paper designed a simple new AC/DC shunt release control circuit in conformity with national standard requirements, introduced each module function of the control circuit and gave the lowest cost control circuit diagram. Simulation experiment shows that the control circuit only uses 14 elements to accomplish pre-setting electromagnetic iron action time, with long time power on shunt release control.
Key words: shunt release; control circuit; lowest cost; long time power on
