[0002] With the rapid development of the electric power industry, the proposal of a new topic of intelligent power grid, and the further research on the automatic control technology of the power distribution system, it is bound to accelerate the process of the automatic control of the power distribution system; at present, the research on the automatic control technology of the power distribution system Started, but due to the large demand for investment in executive agencies and data channels, it has not been fully popularized and applied; the intelligent and automatic monitoring of power distribution systems, that is, for 10KV lines and 10000 / 400V distribution transformers, 10KV load switches , segmental switch and power distribution equipment, and the cost of these terminal equipment is relatively low, and it is correspondingly required that the supporting intelligent monitoring equipment has an adaptable design technology and economy

[0003] For the realization of automatic monitoring of intelligent power distribution system, it is of great significance to realize intelligent monitoring of power system, especially in the current situation of insufficient power supply during peak hours of domestic power supply, intelligent power supply and consumption management is required. Directly distribute the load, and be able to perform remote telemetry, remote signaling, and remote control to achieve the purpose of automatic load regulation; the intelligent and automatic control technology of the power distribution system will greatly improve the safe operation of power distribution equipment in the power system, and is currently in operation Since the distribution transformers, 10KV load switches and section switches cannot be monitored in real time, they are basically out of order, and the user will notify them to repair them; such a power grid operation state will inevitably lead to low power supply quality and high equipment damage rate
