    • PURPOSE: An electronic trip device including a capacitor for supply of a trip coil is provided to enable its size to be reduced by charging a capacitor at a lower voltage than that which is necessary for tripping. CONSTITUTION: An electronic trip device comprises current measuring unit connected to an electronic processing circuit designed to perform protection functions and comparing the measured current with at least one tripping threshold, and to a power supply circuit comprising a power supply capacitor and a unit for regulating the voltage at the terminals of the capacitor according to a preset reference voltage. The electronic processing circuit comprises unit for comparing the measured current with a preset threshold, lower than the tripping threshold. The trip device comprises unit for setting the reference voltage of the regulating unit to the first preset value during a preset period, when power-on of the trip device is performed or when the measured current is equal to or greater than the preset threshold, and to the second preset value, lower than the first value, after the preset period.
    • 目的:提供一种包括用于提供跳闸线圈的电容器的电子跳闸装置,以便通过以比脱扣所需的电压更低的电压对电容器充电来减小其尺寸。 构成:电子跳闸装置包括连接到电子处理电路的电流测量单元,该电子处理电路被设计成执行保护功能并将测量的电流与至少一个跳闸阈值进行比较,并且包括电源电路,该电源电路包括电源电容器和用于调节 根据预设的参考电压在电容器的端子处的电压。 电子处理电路包括用于将测量的电流与预设阈值进行比较的单元,低于跳闸阈值。 跳闸装置包括在执行跳闸装置的上电时或当测量的电流等于或大于预设阈值时在预设时段期间将调节单元的参考电压设置为第一预设值的单元,以及 到第二预设值,低于第一个值,在预设时间段之后。
