Abstract

The present invention discloses a high-tension distribution line fault collection device and method. A signal generation module is configured to send high-frequency signals with different frequenciesto a signal collection module on time, the signal collection module is configured to calculate the high-frequency signals and obtain receiving power and sending power of the signal generation module and the signal collection module and forward the receiving power and sending power to a monitoring terminal server through a GPRS system and a base station, the monitoring terminal server calculates power loss of the signal generation module and the signal collection module according to the receiving power and the sending power, if the power loss is lower than a preset value, the power loss is compared to motion signals, and according to the comparison result, the types and the positions of faults are determined. The high-tension distribution line fault collection device and method can rapidlyand accurately search the faults on the distributing line so as to reduce the power personnel work time and improve the work efficiency.

Description

technical field [0001] The present application relates to the field of electrical technology, in particular to a high-voltage power distribution line fault acquisition device and method. Background technique [0002] The distribution network is one of the important parts of the national power system. The “Thirteenth Five-Year Plan” has gradually rationalized the structure of the power system distribution network. As the end of the power system, the distribution network mainly presents a wide geographical distribution, multiple operation modes, and Close to the user and other characteristics, as the power consumption gradually increases, the scale is also getting larger and larger. [0003] High-voltage distribution network lines are always tripped due to different faults for various reasons, and it is often impossible to find the fault location of the high-voltage distribution network line in time. It is necessary for electric personnel to find the fault point along the line...
