介紹以P87LPC764型單片機(jī)為核心的延時(shí)型漏電繼電器設(shè)計(jì)方案。該方案可供用戶選擇實(shí)現(xiàn)額定動(dòng)作電流和5倍額定動(dòng)作電流下不同的延時(shí)動(dòng)作時(shí)間,并有重合閘設(shè)定選擇功能。解決了以往傳統(tǒng)分立元件帶來的延時(shí)時(shí)間離散性大且不易實(shí)現(xiàn)的弊端。
Abstract:
In this paper, the delay leakage relay based on P87LPC764 is introduced in detail. This system provides different relay times at rating current and 5× rating current for users and also offers superposition brake set selection function. So that it resolves many traditional problems.
