附图说明 Description of drawings

图1是本实用新型一种直流自动切换备用电源供电装置的结构框图。Fig. 1 is a structural block diagram of a DC automatic switching standby power supply device of the present invention.

具体实施方式 Detailed ways

下面结合附图和具体实施方式对本实用新型进行详细说明。The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

如图1所示,本实用新型一种直流自动切换备用电源供电装置,包括主电源U1、备用电源U2、电阻R1、一号二极管D1、二号二极管D2、电容C1以及常闭继电器K1。主电源U1的负极、备用电源U2的负极、电容C1的负极以及电阻R1的一端相连接,并作为该供电装置的公共接地端。主电源U1的正极与一号二极管D1的正极、以及常闭继电器K1线圈的一端相连接。一号二极管D1的负极、电容C1的正极以及二号二极管D2的阴极相连接,并作为该供电装置的电压输出端。常闭继电器K1线圈的另一端与电阻R1的另一端相连接,常闭继电器K1的常闭触点的两端分别连接在备用电源U2的正极、以及二号二极管D2的正极上。As shown in Figure 1, the utility model is a kind of DC automatic switch backup power supply device, including main power U1, backup power U2, resistor R1, No. 1 diode D1, No. 2 diode D2, capacitor C1 and normally closed relay K1. The negative pole of the main power supply U1 , the negative pole of the backup power supply U2 , the negative pole of the capacitor C1 and one end of the resistor R1 are connected together and serve as the common ground terminal of the power supply device. The anode of the main power supply U1 is connected with the anode of the first diode D1 and one end of the coil of the normally closed relay K1. The cathode of the first diode D1, the anode of the capacitor C1 and the cathode of the second diode D2 are connected to each other, and serve as the voltage output terminal of the power supply device. The other end of the coil of the normally closed relay K1 is connected to the other end of the resistor R1, and the two ends of the normally closed contact of the normally closed relay K1 are respectively connected to the positive pole of the standby power supply U2 and the positive pole of the second diode D2.

本实用新型的工作原理是:当主电源U1正常工作时,电容C1两端存有电荷,常闭继电器K1线圈中会流过一定的电流,所以常闭继电器K1常闭触点断开,因此备用电源U2不工作。当主电源U1突然断开时,在这瞬间电容C1放电,使系统不立刻断电,这时由于主电源U1断开,常闭继电器K1线圈中没有电流,常闭继电器K1的触点将会闭合,从而备用电源U2投入工作,对系统供电。The working principle of the utility model is: when the main power supply U1 is working normally, there is charge at both ends of the capacitor C1, and a certain current will flow through the coil of the normally closed relay K1, so the normally closed contact of the normally closed relay K1 is disconnected, so the standby Power supply U2 does not work. When the main power supply U1 is suddenly disconnected, the capacitor C1 is discharged at this moment, so that the system does not immediately power off. At this time, because the main power supply U1 is disconnected, there is no current in the coil of the normally closed relay K1, and the contact of the normally closed relay K1 will be closed. , so that the backup power supply U2 is put into operation to supply power to the system.
