The present application provides an anti-power reverse connection circuit, a power distribution device and a power supply and distribution system. Among them, the power supply reverse connection prevention circuit includes a diode and an execution unit connected in series between the positive incoming terminal and the negative incoming terminal of the circuit breaker. Incoming terminal; when the power supply is in positive connection with the circuit breaker, the diode is cut off, there is no current on the execution unit, and the anti-power reverse connection circuit is in a power-off state. When the power supply is reversely connected to the circuit breaker, the diode is turned on, the execution unit is used to block the closing of the circuit breaker, and / or the execution unit is used to give an alarm prompt for early warning. Completely prevent the short circuit accident caused by the reverse connection of the power supply. In addition, the anti-power reverse connection circuit provided by the present application has a simple structure, and can reduce the volume and cost compared with the prior art.
Description
technical field [0001] The present application relates to the technical field of circuits, and in particular, to an anti-power reverse connection circuit, a power distribution device and a power supply and distribution system. Background technique [0002] The battery is an important part of the power supply and distribution system. As the DC backup power supply in the power supply and distribution system, it provides a safe, stable and reliable power guarantee for the communication equipment when the AC power supply is interrupted or fails for a short time. of normal operation. In power supply and distribution systems, such as figure 1 As shown, the battery 1 is generally connected to the system bus through the circuit breaker 2 . Due to manual wiring, such as figure 2 The operation error of the reverse connection of the cable of the battery 1 shown is unavoidable, and equipment damage and safety accidents caused by the reverse connection of the battery 1 often occur. ...
