Low voltage intelligent power distribution system

The utility model provides a low voltage intelligent power distribution system comprising an on-site device layer, a communication management layer, and a monitoring management layer. The on-site device layer is communicated with the communication management layer by adopting the RS485 or the MODBUS communication way. The monitoring management layer and the communication management layer are in a wireless transmission by the Ethernet or the GPRS. The on-site device layer comprises a multifunctional instrument, a network instrument, an intelligent power factor compensator, an intelligent motor controller, and an intelligent breaker. The communication management layer comprises an intelligent monitoring front terminal. The monitoring management layer comprises a monitoring host, a monitoring slave, and a remote management device. By using the low voltage intelligent power distribution system, the operation temperature of the measured part, the wearing of the breaker contact, and other non-electric quantity parameters can be provided, the early detection and the protection of the short circuit failure and other high level intelligent protection can be realized, and the GPRS wireless transmission function can be realized.
