Description

technical field

[0001] The invention relates to the technical field of power supply management, in particular to an intelligent power distribution device and an intelligent power distribution system. Background technique

[0002] According to the size of the equipment power, there are two ways to expand the traditional new equipment. They are directly using the DC distribution branch of the old power supply of the original site to connect to the new equipment and adding a set of DC power supply. In the first expansion method, since the new equipment is connected to the circuit of the primary power-off contactor to obtain power, when an AC power failure occurs, the newly-added equipment will continue to work until the primary power-off contactor is disconnected, which will reduce the battery life. The length of backup power; the second expansion method, the newly added equipment is connected to the newly added power supply, and the circuit is opened once after power off, so a...
