Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an ultrasound diagnostic apparatus for mounting on a commercial camera, and a method of diagnosing an electric device using the same. BACKGROUND OF THE INVENTION [0002]

The present invention relates to an ultrasonic diagnostic apparatus for detecting a defect occurring in a power facility and a method of diagnosing a power apparatus using the same. More particularly, the present invention relates to an ultrasonic diagnostic apparatus configured to mount a general high magnification camera, The present invention relates to an ultrasonic diagnostic apparatus with a commercial camera and a method of diagnosing an electric power equipment using the same.

In general, power facilities are required to be continuously monitored, removed from risk factors, and replaced with old facilities due to changes in the environment around the distribution lines and damage caused by equipment failure.

For example, various instantaneous inspection methods are used to prevent failures such as insulator failure, equipment failure, connection material failure, etc. As a representative example, a power distribution line A momentary method, a live wire inspection method for measuring the sharing voltage by using a visual and fork type suspension type voltage measuring instrument by accessing live wire distribution equipment by using a live wire bucket truck in a live wire state, An instantaneous method using an ultrasonic measurement method, a thermal imaging camera measurement method, an RFI (radio frequency interference), and an optical measurement method is used to measure a measurement result of an ultrasonic wave to prevent a failure of a distribution line.

On the other hand, it is practically impossible to visually measure the abnormality of the facility because the electric power facility is located at a distance of 10 m or more from the ground.

In addition, since the live wire operator inspects the live wire bucket truck for inspection, it is possible to see the equipment at a close distance by the naked eye, but in the case of a narrow space between the insulator and insulator, or a minute crack existing on the opposite side from the inspector It is very difficult to check, it takes a lot of time to check, relatively high cost, and inefficiency.

The ultrasonic measuring method judges the defect and position of the electric power facility subjectively according to the current hearing and judgment, and not only a highly trained workforce is required in reading the defect, but the subjective judgment is not accurate, There is a problem that can occur. In addition, since the ultrasonic wave is inspected only for the electric power facilities caused by the discharge phenomenon, it is impossible to diagnose simple damage, installation failure, and raw material failure that do not cause discharge, and such a potential risk is not diagnosed .

Since the thermal imaging camera measurement method diagnoses a failure by measuring heat generated when deterioration progresses in a power facility, it can not be extracted in the case of a facility in which heat is not generated. In fact, in special high voltage (22,900v) lines of power plants, heat is not generated in the cracks of the agitator in most cases. In addition, there is a problem that heat is not generated even when the foreign object contacts or the bolt is loosened.

Since the instantaneous method using the RFI (Radio Frequency Interface) is very severe in the case of a dense area in an urban area or a factory, it is difficult to discriminate the noise from the power equipment, It is impossible to distinguish. In addition, since it is impossible to analyze the waveform, it is difficult to grasp the type of the fault and to grasp the degree of the fault.
