介紹以P87LPC764型單片機為核心的延時型漏電繼電器設計方案。該方案可供用戶選擇實現額定動作電流和5倍額定動作電流下不同的延時動作時間，并有重合閘設定選擇功能。解決了以往傳統分立元件帶來的延時時間離散性大且不易實現的弊端。
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.
