Abstract
本申请提供一种绝缘电阻检测电路、方法、装置及其存储介质,用于检测绝缘电阻是否发生故障,包括:状态控制单元、第一分压支路、第二分压支路和处理器;状态控制单元跨接在待检测装置电源的正极和负极之间;第一分压支路与第一电容并联,得到第一电压波形;第二分压支路与第二电容并联,得到第二电压波形;处理器与状态控制单元、第一分压支路和第二分压支路连接,根据当前时刻的第一电压波形和第二电压波形,计算当前时刻之前设定时长内不同时刻的第一电容电压特征值和不同时刻的第二电容电压特征值;根据不同时刻的第一电容电压特征值和/或不同时刻的第二电容电压特征值,确定下一切换时刻,在下一切换时刻控制状态控制单元进行状态切换。
