Embodiment

[0034] Example: see figure 1 , 2 , the medium-voltage carrier system applied to the centralized copying platform of the rural network according to the present invention is to set the main carrier machine 1 and the slave carrier machine 2 respectively at the two ends of the 10KV overhead line 5; the main carrier machine 1 passes through the Ethernet port through the switch Or the RS-232 serial port communicates with the main station system; the slave carrier machine 2 communicates with the power distribution terminal equipment through the Ethernet port or the RS-232 serial port through the switch.

[0035] The main carrier machine 1 transmits the carrier signal sent by the main station system to the capacitive coupler 3 through the carrier signal interface, and then injects it into the signal transmission loop formed by the 10KV overhead line and the ground through a combined filter.

[0036] The carrier signal transmitted by the signal transmission loop composed of 10KV overh...

Abstract

The invention discloses a medium-voltage carrier system applied to a rural network centralized metering platform. A main carrier machine and an auxiliary carrier machine are arranged at two ends of a 10 KV overhead line, respectively. The main carrier machine is communicated with a main station system through an Ethernet port or a RS-232 serial port. The auxiliary carrier machine is communicated with power distribution terminal equipment through an Ethernet port or a RS-232 serial port. Carrier signals, received from the main station system, are sent to capacity couplers by the main carrier machine through a carrier signal interface; then enter into a signal transmission loop, composed of the 10KV overhead line and the ground, through a coupling filter; and are sent to the auxiliary carrier machine through an isolation capacitance and the coupling filter. Original data, sent from the main carrier machine, is restored by the auxiliary carrier machine and then sent to the power distribution terminal equipment. The network carrier communication system has the large-scale full-coverage communication networking capacity and comprehensively meets the acceptance indicators, namely telemetering, remote signaling and remote control systems of the distribution automation made by the State Grid Company.

Description

Technical field: [0001] The invention relates to a medium-voltage carrier system applied to a centralized copying platform of a rural network. Background technique: [0002] In order to implement the scientific outlook on development, better serve the construction of a new socialist countryside, and actively implement the development goals of the State Grid Corporation of China's "one strong and three excellent" modern company and the agricultural power development strategy of "new countryside, new power, and new services", further promote The scientific and technological progress of rural power grids will give full play to the supporting role of science and technology, rely on scientific and technological means to accelerate the construction of new rural areas, and actively promote the construction of "comprehensive monitoring" and "smart power consumption" in rural power grids. [0003] The overall planning and construction of rural power communication informatization is a...
