Tool, is to be judged there is limitation and non-science by conventional experience under normal circumstances.
(4) the in-depth study function to detecting data is lacked.Currently during inspection, used detection means with
Method can not be handled repeated detection data, and large quantities of detection data can not be used effectively, to equipment state with surplus
The prediction in remaining life-span generates limitation.
When being broken down in distribution network overhead line, the ultrasonic wave of diverging, therefore, mesh are produced in space due to shelf depreciation
The device of preceding common distribution network overhead line fault detect applies ultrasound examination more.But existing ultrasonic detection device positioning
Precision is very low, thus can bring that detection efficiency is low, testing cost is high to the fault detect of distribution overhead line and detection security is poor
The problem of.
In summary, the detection of current distribution overhead line is present clearly disadvantageous, in order to improve detection efficiency, save into
Originally and security is improved, improves and the positioning precision of line fault is particularly important.Therefore, detection device accurately positions energy
Power is to ensureing that power network safety operation will undoubtedly play important impetus.
The content of the invention
To solve the problems, such as that the efficiency of current distribution overhead line detection is low, cost is high and security is poor, the embodiment of the present invention
A kind of infrared comprehensive detection device of distribution overhead line ultrasonic wave is provided, described device includes ultrasound examination module, the first top
Spiral shell instrument module, controller and infrared scan module；
The ultrasound examination module be used for gather distribution overhead line defective locations caused by ultrasonic signal, will collect
The ultrasonic signal send to the controller；
First gyro module is used for the first orientation information for determining the ultrasound examination module, by described first
Azimuth information is sent to the controller；
The controller and the ultrasound examination module, first gyro module and infrared scan module electricity
Connection, control letter is sent to the infrared scan module according to the intensity of the ultrasonic signal and the first orientation information
Number；
The infrared scan module is used for infrared scan, and infrared scan direction is adjusted according to the control signal.
The present invention is automatically positioned on the basis of ultrasound examination faults of overhead lines of distribution network with reference to infrared scan auxiliary, from
And the positioning precision of faults of overhead lines of distribution network detection is improved, it is achieved in efficiency high, the cost of faults of overhead lines of distribution network detection
Low and safe effect.
