Whole net voltage monitoring device

Abstract

The invention provides a whole net voltage monitoring device which comprises a power supply module and a circuit system powered by the power supply module. The invention is characterized in that: the circuit system comprises a one-chip microcomputer, a wireless remote transmission module, a communication module and a wireless transmitting and receiving module, wherein, a communication port RX1 and a communication port TX1 of the one-chip microcomputer are correspondingly connected with a communication port RX1 and a communication port TX1 of the wireless remote transmission module, a communication port RX2 and a communication port TX2 of the one-chip microcomputer are correspondingly connected with a communication port R0 and a communication port D1 of the communication module, and a communication port RXD0 and a communication port TXD0 of the one-chip microcomputer are correspondingly connected with a communication port RX0 and a communication port TX0 of the wireless transmitting and receiving module. The device provided in the invention not only can overcome some common problems in low-voltage distribution transformation at present, but also accords with current policies for building new villages and new electric power networks and promoting reconstruction of electrified villages in China, and lays a foundation for intellectualization, automation, remote measurement and remote control of rural electric power.

Description

technical field [0001] The invention provides a whole network voltage monitoring device, which belongs to the technical field of digital acquisition and communication of distribution network parameters of electric power systems. Background technique [0002] With the implementation of the national smart grid planning, intelligent informationization of power generation, transmission, and power transformation has been completed. However, in view of the complexity of low-voltage distribution network lines, the diversity of loads and the harsh environment, the intelligent There is no perfect technology and case. At present, the voltage on the side of urban and rural civil and industrial low-voltage distribution lines is basically in a state of no monitoring. During the investigation, we learned that in many residential areas or rural areas, accidents of electrical appliances burning out due to overloaded lines often occur. Generally, there are many branches on the 400V to 35kV ...

AI Technical Summary

Problems solved by technology

Through a large number of investigations, it is found that the following problems are common in low-voltage power supply, especially in rural areas: 1) There is a lack of voltage acquisition terminals in power grids at all levels; 2) There are unqualified voltages; 3) There is a lack of effective voltage regulation means
