Problems solved by technology

[0002] 10KV distribution lines are widely used in my country's power supply system, but in southern China, due to the influence of the humid climate in the south, 10KV distribution lines are prone to failure. Judging the insulation resistance of the line to find the fault, that is, the insulation test comparison method, but this method requires manual line inspection to find the fault, which is very time-consuming and laborious. In addition, this method is more effective for pure overhead lines, but now pure overhead lines Very few, most of them are overhead lines, or mixed lines of overhead lines and cables. Not only can the line faults not be seen by inspection, but also because most of the line faults are high-resistance faults, in special cases the insulation resistance of the normal section is lower than that of the faulty section. It is difficult for emergency repair personnel to judge from the test data, the possibility of misjudgment is very high, and it is difficult to accurately find out the fault point

Abstract

The invention discloses a high-frequency trail transmission positioning system and a positioning method. The high-frequency trail transmission positioning method comprises the following steps: a signal output end transmits test signals at least containing AC signals in a set frequency to a to-be-tested line; a signal detection end is close to the to-be-tested line, the AC signals in the set frequency in the to-be-tested line are sensed, and detection signals are obtained; the detection signals are processed to obtain detection data and position information; the detection data and the positioninformation are transmitted to a mobile terminal; the mobile terminal receives the detection data and the position information; the mobile terminal compares the detection data and a preset value; andif the detection data are consistent with the preset value, the mobile terminal generates fault signals, and the fault signals and the corresponding position information are outputted. The high-frequency trail transmission positioning method can quickly and accurately check a fault point, fault checking by manual line patrol is not needed, and the fault checking efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of power fault detection, in particular to a high-frequency test delivery positioning system and a positioning method.
