Description

technical field [0001] The invention relates to a power distribution parameter monitoring and control system and a control method, belonging to the technical field of power distribution monitoring. Background technique [0002] With the increasing requirements for power supply quality monitoring in distribution rooms, building power distribution rooms, and network server monitoring centers, power distribution monitoring technology has been widely used. The power distribution cabinet is one of the main equipment in the computer room, power distribution room and monitoring center. The mains incoming circuit passes through the power distribution cabinet to divert several outgoing circuits. The equipment obtains power supply by connecting the outgoing circuits. The power distribution cabinet collects the electrical parameters of the incoming and outgoing circuits, analyzes and compares the preset thresholds For the monitoring of power distribution system, the power distribution...
