Title:
POWER SOURCE REVERSE CONNECTION PREVENTION CIRCUIT, POWER DISTRIBUTION APPARATUS, AND POWER SUPPLY AND DISTRIBUTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/100074
Kind Code:
A1
Abstract:
Provided are a power source reverse connection prevention circuit, a power distribution apparatus, and a power supply and distribution system. The power source reverse connection prevention circuit comprises a diode and an execution unit, which are connected in series between a positive incoming line terminal and a negative incoming line terminal of a circuit breaker, wherein a positive electrode of the diode points to the negative incoming line terminal of the circuit breaker, and a negative electrode of the diode points to the positive incoming line terminal of the circuit breaker. When a power supply source is positively connected to the circuit breaker, the diode is cut off, there is no current on the execution unit, and the power source reverse connection prevention circuit is in a power-off state. When the power source is reversely connected to the circuit breaker, the diode is turned on, and the execution unit is used for blocking the circuit breaker from being closed, and/or the execution unit is used for giving an alarm prompt to perform an early warning. A short-circuit accident caused by the reverse connection of a power supply source is completely prevented. Moreover, the power source reverse connection prevention circuit provided in the present invention is simple in terms of structure, and compared with the prior art, the volume and the cost thereof can be reduced.
