Monitoring and fault locating device used for grid power-distribution circuit

Abstract

The invention discloses a monitoring and fault locating device used for a grid power-distribution circuit. The device includes a collector, an indicator and a display, and is characterized in that the collector comprises a wireless module JP1, a single-chip microcomputer U1, a GPRS module GM and an antenna TX1; the output end of the wireless module JP1 is connected with the input end of the single-chip microcomputer U1, and the output end of the single-chip microcomputer U1 is connected with the input end of the GPRS module GM; the indicator includes a wireless module JP2, a single-chip microcomputer U2, a signal collecting module T1 and an antenna TX2; the output end of the signal collecting module T1 is connected with the input end of the single-chip microcomputer U2, and the output end of the single-chip microcomputer U2 is connected with the input end of the wireless module JP2. Electricity workers can know the states of all monitoring points on the circuit in real time and achieve remote monitoring of data without being on the spot.

Description

technical field [0001] The invention relates to a monitoring and fault location device for distribution lines of a power grid, which belongs to the technical field of microcomputer automatic monitoring and control. Background technique [0002] my country has always had the problem that distribution lines form a network structure with complex load types, complex topography in most areas, and high line failure rate, which brings huge work pressure and difficulty to line maintenance personnel. However, traditional line fault indicators have simple functions and are difficult to Accurately detect line faults, resulting in a large area of ​​blackouts for a long time, which brings great inconvenience to the work of the power sector, enterprise production, and residents' daily use of electricity. Contents of the invention [0003] Purpose of the invention: The present invention provides a monitoring and fault location device for power grid distribution lines that can determine th...
