The embodiment of the invention discloses a control method and device of a rapid insulation detection circuit and electronic equipment, and relates to the technical field of circuit detection. The insulation detection circuit comprises a sampling resistor and an insulation bridge arm switch and is used for acquiring the insulation resistance of a detected object; the control method comprises the following steps: closing the insulating bridge arm switch; a transient voltage is obtained every preset time interval; acquiring a first steady-state voltage according to the transient voltage and a time point corresponding to the transient voltage; and obtaining the insulation resistance according to the first steady-state voltage. The first steady-state voltage can be obtained without waiting for the insulation detection circuit to be stable, the insulation resistance is obtained according to the first steady-state voltage, and the insulation detection speed and precision are improved.

    本发明实施例公开了一种快速绝缘检测电路的控制方法、装置及电子设备,涉及电路检测技术领域。绝缘检测电路包括采样电阻和绝缘桥臂开关,绝缘检测电路用于获取被检测物的绝缘电阻;控制方法包括:闭合绝缘桥臂开关;每间隔预设时间间隔获取一个瞬态电压;根据瞬态电压和瞬态电压对应的时间点,获取第一稳态电压;根据第一稳态电压,获取绝缘电阻。不需要等待绝缘检测电路稳定即可获得第一稳态电压,根据第一稳态电压得到绝缘电阻,提高绝缘检测的速度和精度。
