Problems solved by technology

This patent can only determine which line is faulty, but cannot determine the specific location of the fault in the line, so it still takes a lot of time and manpower to determine the specific location of the fault when troubleshooting

Embodiment Construction

[0016] The present invention will be further described below in conjunction with accompanying drawing. As shown in the figure, a distribution network fault location monitoring system includes a fault locator 1 for measuring the specific location of a fault in a line through a traveling wave signal, a receiving device 2 for receiving a signal from the fault locator 1, and a fault information display Device 3 and the portable terminal 4 that can receive fault position information; Described fault locator 1 is installed in the two ends of every line in distribution network and every line installs at least two; Described signal receiving device 2 and fault information Display device 3 is connected by local area network; Described fault locator 1 comprises signal detection device 11 for receiving fault pulse signal, satellite time receiving device 12 for synchronously receiving satellite time signal, wireless communication device 13, collects all kinds of signals and Carry out the ...

Abstract

The invention discloses a fault positioning monitoring system for a distribution network. The system comprises fault positioners, a signal receiving device and a fault information display device, wherein the fault positioners are used for measuring the specific positions of ground or short-circuit faults in lines by fault voltage and current traveling wave signals; the signal receiving device is used for receiving signals from the fault positioners; the fault positioners are arranged at the two ends of each line in the distribution network; each line is provided with at least two fault positioners; and the signal receiving device is connected with the fault information display device by a local area network. The fault positioning monitoring system has the advantages that: the faults can be accurately positioned to greatly shorten time for searching for the positions of the faults; and after a specific line with the fault is determined, loss caused by the fault can be decreased by cutting the circuit of the line off and simultaneously recovering the power supply of the other lines without the fault.

Description

technical field [0001] The invention relates to a distribution network fault location monitoring system, in particular to a distribution network fault location monitoring system capable of accurately measuring the location of a fault. Background technique [0002] At present, my country's electric power sector widely adopts mechatronic fault indicators on the 10kV distribution network. When a fault occurs, it is necessary to send line inspectors to search for it all the way. Due to the many branch lines of the distribution network, it is very inconvenient to find faults, and often consumes a lot of manpower, material resources and time. For rural power grids, it is even more difficult to cross mountains and rivers [0003] Chinese patent CN1286405A discloses a method based on the installation of multiple monitoring terminals (such as FTUs) on the distribution network, circuit breakers, breaking switches, and contact switches, and numbering them to form a network matrix to o...
