用于电源的电子保险装置
摘要：
针对为直流设备供电的电源的保险电路，其中根据本发明提出，所述保险电路设置在电源的输出端，并且在正电源端子(3)和通向直流设备的正输出端子(1)之间设置了开关元件(S1)以及连接在开关元件(S1)和正输出端子(1)之间的扼流圈(L1)，其中扼流圈(L1)与正输出端子(1)相连的一侧连接到输出端电容(C2)，并且扼流圈(L1)与开关元件(S1)相连的一侧连接到与输出端电容(C2)并联的二极管(D1)的阴极侧，以及设置了用于开关元件(S1)的控制装置，所述控制装置根据在保险电路中测得的电流来切换开关元件(S1)。
摘要（英）：

The invention relates to a security circuit for a power supply feeding a DC system. According to the invention, the security circuit is disposed on the outlet of the power supply, and a switch element (S1) is disposed between the positive power supply clamp (3) and the positive output clamp (1) towards the DC system, and a choke coil (L1) that is disposed between the switch element (S1) and the positive output clamp (1). Said choke coil (L1) is connected to an output capacitor (C2) on the side connected to the positive output clamp (1), and the side of the choke coil (L1) that is connected to the switch element (S1) is connected to the cathode side of a diode (D1) that is connected in parallel to the output capacitor (C2). Said security circuit also comprises a control for the switch element (S1), connecting the switch element (S1) in accordance with the power measured in the security circuit.
