本实用新型的工作原理是：R0为电流取样电阻，为了防止计算机在启动时产生的大电流造成电路的安全隐患，由C1、R1、RP1及非门F1组成了开机保护延时电路，计算机负载RL开始启动时，C1上无电压，此时非门F1输出低电平，与非门F3则输出高电平，使VT2处于截止状态，继电器K1不工作，其触点仍保持常闭状态，计算机负载RL可获得正常供电。当C1的端电压逐渐升高到一定值时，非门F1发生翻转，输出端变为高电平，开机保护启动电路结束工作，此后与非门F3的输出状态则由RP2、R2、VT1及R0等组成的电流检测电路控制。 The working principle of the utility model is: R0 is a current sampling resistor, in order to prevent the large current generated by the computer from causing potential safety hazards in the circuit, C1, R1, RP1 and NOT gate F1 form a start-up protection delay circuit, and the computer load When RL starts to start, there is no voltage on C1. At this time, the NAND gate F1 outputs low level, and the NAND gate F3 outputs high level, so that VT2 is in the cut-off state, the relay K1 does not work, and its contacts remain in the normally closed state. The computer load RL can obtain normal power supply. When the terminal voltage of C1 gradually rises to a certain value, the NAND gate F1 flips over, the output terminal becomes high level, and the power-on protection startup circuit ends its work. After that, the output state of the NAND gate F3 is controlled by RP2, R2, VT1 and R0 and other components of the current detection circuit control.
