Abstract

The invention discloses a low-voltage power distribution system and a data communication method of the low-voltage power distribution system. The low-voltage power distribution system comprises a CCO carrier module, a distribution transformer sensing terminal and a switch carrier module which are located in a power distribution area, and a meter box carrier module and an electric meter carrier module which are located in a transformer area. The ammeter carrier module is used for performing power grid meter reading and acquiring electric quantity of an ammeter; the meter box carrier wave module is used for measuring electric quantity of a meter box incoming line. And the distribution transformer sensing terminal is used for sending the measured total electrical quantity of the transformer area to the gateway. And the gateway carries out carrier communication with the electric meter carrier module, the switch carrier module and the meter box carrier module through the CCO carrier module. According to the embodiment of the invention, electrical quantity acquisition, control and information interaction of the primary side equipment and the secondary side equipment are realized through the concentrator, integration of the primary side equipment and the secondary side equipment is realized, the operation level, the operation and maintenance quality and efficiency of the power distribution equipment are improved, and the reliability and universality of the equipment are improved.

Description

technical field [0001] Embodiments of the present invention relate to low-voltage power distribution technology, and in particular to a low-voltage power distribution system and a data communication method for the low-voltage power distribution system. Background technique [0002] The interface between primary equipment and secondary equipment does not match, compatibility, scalability, and interchangeability are poor, and there is a lack of linkage testing mechanism for primary equipment and secondary equipment. Not only primary equipment and secondary equipment manufacturers are prone to liability disputes, but also cannot support line loss calculation and single-phase ground fault detection requirements, and remote signal jitter and equipment condensation will also occur. [0003] Traditional low-voltage electrical detection secondary equipment needs to be re-wired, from the household meter to the meter box, from the meter box to the branch, from the branch to the switch...
