As is well known, distribution lines that supply electricity from substations to cadastre are made up of complicated trunks and branches because they have to supply power to a large number of consumers.

Therefore, in case of ground fault (when the wire is disconnected and grounded on the power distribution line) or short circuit (when the wires on different phases are caught), fault current and voltage occur, A lot of efforts are needed to find out.

In the past, when a fault current and a voltage are generated in a distribution line, a substation operator is operated by a substation operator in order to find faulty current and voltage, It was a common method to find out the merits by exchanging them.

However, in the case of the above-described method, a long time is required as the recovery time is long and the power saving time is long, resulting in frequent inconveniences of power consumers.

Accordingly, there is a need for a method for improving the reliability of the power supply and the quality of service for the customer by shortening the power failure time by quickly grasping and recovering the position of the power supply when an accident occurs in the power distribution line.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Before describing the present invention, the following specific structural or functional descriptions are merely illustrative for the purpose of describing an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention may be embodied in various forms, And should not be construed as limited to the embodiments described herein.

In addition, since the embodiments according to the concept of the present invention can make various changes and have various forms, specific embodiments are illustrated in the drawings and described in detail herein. However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

In the present invention, when a failure such as cracks occurs in a power distribution facility, an ultrasonic signal waveform different from a normal state is generated, and it is found out that the waveform is different according to the abnormal type.

First, the relationship between the ultrasonic signal and the abnormal type will be described. FIG. 1 shows a normal waveform in a state where no failure occurs in the power distribution facility. FIG. 2 shows a waveform when an arc discharge is occurring FIG. 3 shows waveforms at the time of corona discharge, and FIG. 4 shows waveforms at the time of occurrence of tracking.

Referring to FIG. 1 of the normal waveform, a certain type of waveform is detected over time and there is little change in amplitude.

In the case where the waveform of the ultrasonic signal received and analyzed through the ultrasonic wave detecting device is as shown in FIG. 1, all the distribution facilities in the area to be inspected, that is, the area provided with the ultrasonic wave received by the ultrasonic wave detecting device, are all in a normal state, .

Referring to FIG. 2, when the arc is generated, the amplitude of the waveform increases when the arc is generated. When the arc is not generated, a waveform similar to that at the time of the corona discharge appears.

Referring to FIG. 3, in the case of the corona discharge, a waveform having a smaller amplitude than the waveform at the time of the arc discharge in FIG. 2 appears continuously when a surface discharge is generated on the surface of the insulator.

Referring to FIG. 4, it can be seen that since the cracking of the insulator proceeds while tracking of the corona has already progressed for a considerable period of time, a waveform having a larger amplitude than the corona discharge waveform appears continuously.

When the ultrasonic wave received through the ultrasonic wave detecting device has the type shown in FIG. 2 to FIG. 4, it corresponds to a defective spot where a failure of the power distribution equipment providing the ultrasonic wave has occurred.

The present invention can detect the occurrence of defective parts, the abnormal type of defective parts, and the progress of the defective part among the distribution facilities of the entire water level by analyzing the waveform and analyzing the ultrasonic signals generated in the distribution facility, The present invention provides an ultrasonic wave detecting apparatus capable of effectively detecting ultrasonic waves generated in a power distribution facility at a spaced apart position, thereby facilitating inspection of defects in a distribution line using ultrasonic waves.

5 is a perspective view of an ultrasonic wave detecting apparatus for checking a defect in a distribution line according to the present invention, FIG. 6 is a perspective view of the ultrasonic wave detecting apparatus shown in FIG. 5 according to the present invention, These figures are for explaining an ultrasonic wave detecting apparatus for checking a defect in a distribution line.

5 and 6, the ultrasonic wave detecting apparatus 100 according to the present invention includes a main body 110 and a sighting device 150. As shown in FIG.

According to the present invention, the main body 110 includes a cone-shaped signal collecting tube 120, an ultrasonic sensor 130, and a housing 140.

The cone-shaped signal collecting tube 120 has an inclined inner surface 122 and is formed in a shape such that the diameter gradually decreases as in a conical shape.

The signal collecting tube 120 according to the present invention blocks noise signals flowing from the outside rather than the inspection object area where the ultrasonic signals are received and adjusts the size of the inspection object area where the ultrasonic signals are collected according to the distance to the inspection object .

At this time, the ultrasound signal has a short wavelength and is difficult to diffract and has strong linearity.

Therefore, when the signal collecting tube 120 has the inclined inner surface 122 and the diameter is gradually reduced as in a conical shape as in the present invention, the inclined inner surface 122 is formed to be extended Ultrasonic waves generated in the inspection target area go straight into the signal collecting pipe 120. However, noise signals generated outside the inspection target area, for example, wind noise due to the vehicle speed when moving the vehicle, vehicle noise in the urban area, The noise signal generated by an insect or the like that is generated is blocked and can not proceed to the interior of the signal collection tube 120.

According to the signal collecting tube 120 of the present invention, the size of the inspection object area where the ultrasonic signal is received by the signal collecting tube 120 is adjusted according to the distance between the signal collecting tube 120 and the inspection object area. It is possible to do.

7, when detecting an ultrasonic signal from a distribution facility on the ground on the ground using an ultrasonic wave detecting device, the angle at which the oblique side extends from the central axis of the signal collecting tube 120 is d, Assuming that the distance to the power distribution facility to be inspected is l, the radius R that determines the size of the inspection subject area to be subjected to ultrasonic reception is determined by R? L * tan d.

That is, by adjusting the distance l to the object to be inspected, the size of the inspection object area can be adjusted.

Therefore, the operator can adjust the distance to the inspection target area so that the inspection target area includes the whole distribution facility on the whole pole or only one specific distribution facility on the pole.

That is, it is possible to detect by using one ultrasonic wave detecting device whether or not an area having a defective spot is detected and a defective part of the power distribution equipment specifically in the defective spot area.

According to the present invention, an ultrasonic sensor 130 is installed on the lower surface of the signal collecting tube 120 to receive ultrasonic signals transmitted through the signal collecting tube 120.

The sensed ultrasonic signal is transmitted to the ultrasonic analyzer 10 via the input terminal 28 of the ultrasonic analyzer 10 and is transmitted to the ultrasonic analyzer 10 through the ultrasonic wave analyzer 10, The operator can confirm whether or not it is included.

According to the present invention, the housing 140 includes the signal collecting tube 120 to form the outer shape of the main body 110, and the aiming device 150 is installed on the outer side.

A circuit for filtering and amplifying the ultrasound signal received through the ultrasonic sensor 130 is installed in the housing 140 and a knob 146 is provided on the lower surface of the housing 140. The lower surface of the knob 146 is connected to an ultrasonic analyzer And a connection terminal 147 to which a line connected to the terminal 10 is connected.

According to the present invention, a display device for displaying received ultrasonic signals may be installed in the ultrasonic wave detecting apparatus.

In the case where a display device for analyzing an ultrasound signal received by the main body 110 and displaying a signal of a target band is provided, the ultrasound detection device can be used without the ultrasound analysis device 10 described later. In this case, The ultrasonic wave detecting device 100 may be formed as a single body.

According to the present invention, a laser point 145 is provided on the outer surface of the housing 140, and the laser point 145 enables an area to be inspected to be checked by the ultrasonic wave detecting device to be identified even in the dark time such as at night, It enables work.

According to the present invention, the ultrasonic detecting apparatus 100 includes the aiming apparatus 150. [ The aiming device 150 is of the same type as a sighting telescope used in a gun or the like, and is installed in the housing 140.

The ultrasonic wave detecting apparatus 100 is attached to the side surface of the signal collecting tube 120 when the signal collecting tube 120 is contoured without a separate housing 140. The aiming telescope enables the sighting of the signal collection tube 120 of the ultrasonic detecting apparatus 100 to be accurately sighted by the naked eye, that is, the area where the ultrasonic signal is received, and the signal collecting tube 120 It is possible to accurately obtain the ultrasonic reception area by the ultrasonic wave receiving area.

That is, since the field of view through the aiming device corresponds to the ultrasonic receiving area by the signal collecting tube 120 or can be confirmed, it becomes possible to specify the individual electric distribution facility and receive the ultrasonic signal.

In order to separate the ultrasound signals from the respective distribution facilities on the electric pole, the signal collecting pipe 120 must be accurately aimed to receive ultrasonic signals from only the distribution facility to be inspected, .

Particularly, according to the present invention, the distance between the power distribution facilities is relatively close to each other because the ultrasonic signal from the power distribution facility on the ground is received from the ground.

However, when the aiming device is used, it is possible to accurately aim the signal collecting tube 120 toward the power distribution apparatus to receive the ultrasonic signal, and the ultrasonic receiving area by the signal collecting tube 120 is visually confirmed through the aiming device , It is possible to ensure that only the power distribution facility to be inspected is located accurately in the area to be subjected to ultrasonic wave reception while moving.

The ultrasonic analyzer 10 includes a receiving circuit 12, an amplifying circuit 14, a filter circuit 16, a calculating device 18, a battery, and the like.

FIG. 11 is a block diagram for specifically explaining the peak detecting module of FIG. 10 is a block diagram specifically illustrating the automatic gain control module of FIG.

10 to 12, an ultrasonic wave detecting apparatus 100 according to an embodiment of the present invention includes an ultrasonic wave detecting module 100-1, an amplifying module 100-2, a peak detecting module 100-3, And an automatic gain control module (Automatic Gain Control Module) 100-4.

On the other hand, the FFT transforming unit 100-3d can implement a Fourier transform function indicating the magnitude of each frequency component included in a time function that can be represented by overlapping sine waves of different frequencies. Control and so on.

The automatic gain control module 100-4 performs a function of amplifying / attenuating the input signal by N-fold so that the peak value detected from the peak detection module 100-3 is within a predetermined range, It is used effectively when searching for a point (Pin Point).

In addition, by setting the output level (dB) value to detect the pin point and operating this automatic gain control function, more accurate pin point can be detected.

12, the automatic gain control module 100-4 includes a Gain Controlled Amplifier (GCA) 100 for amplifying a signal according to a peak value detected from the peak detection module 100-3 A detector 100-4b for detecting and outputting a specific amplitude component and a loop filter 100 for controlling the amplitude distortion by loop-filtering the output of the detector 100-4b -4c).

The operation of the gain control amplifier (GCA) 100-4a configured as described above will be described. The input signal U (t) is amplified in proportion to the gain of the gain control amplifier (GCA) 100-4a, , The output Y (t) is input to the detector 100-4b to obtain the amplitude component Vd (t) of the output Y (t).

Then, the Vd (t) signal is passed through the loop filter 100-4c to obtain the control signal Vo (t) of the gain control amplifier (GCA) 100-4a.

The gain of the gain control amplifier (GCA) 100-4a is changed in accordance with the control signal Vo (t), and the magnitude of the output Y (t) approaches the magnitude Vr of the desired signal.

Therefore, the ultrasonic detection apparatus 100 of the present invention can efficiently control the signal-to-noise ratio using the peak detection module 100-3 and the automatic gain control module 100-4, By detecting the pinpoint, it is possible to increase the amplification ratio more than other equipments, and it is possible to realize a revolutionary DOV (Detecting On Vehicle) method.

In addition, the ultrasonic analyzer 10 according to the present invention adjusts the gain of the received signal according to the voltage value output from the automatic gain control module 100-4 of the ultrasonic wave detecting device 100, (VCA) 10-1 for outputting only a predetermined low-frequency component of the signal output from the voltage control amplifier (VCA) 10-1, And a second amplification unit 10-2 for amplifying and outputting a signal output from the first low-pass filter and the amplification unit 10-2 at a predetermined level (about 10 times) A frequency modulator 10-5 for frequency modulating the signal output from the second amplifying unit 10-3 on the carrier oscillation having a frequency generated by the digital function generator 10-4, A second low-pass filter (10-k) for passing only a predetermined low-band component of the signal output from the frequency modulator (10-5) And a third low-pass filter for amplifying the signal output from the second low-pass filter 10-6 to a predetermined level (about 25 times) (For example, arc discharge, corona discharge, tracking occurrence, etc.) according to a specific signal waveform in response to a signal output from the third low-pass filter and the amplification unit 10-7, And an audio amplifier 10-9 receiving the signal output from the third low-pass filter and the amplifying unit 10-7 and amplifying the received signal through a normal speaker A band-pass filter 10-10 for passing only a predetermined band component of the signal output from the third low-pass filter and the amplifier 10-7, And a dB converter 10-11 for logarithmically converting the signal spectrum to a decibel (dB) scale.

In other words, the ultrasonic analyzer 10 configured as described above can minimize the measurement data loss even when the temperature is rapidly changed due to the temperature compensation to the temperature-sensitive amplification circuit, and the multi-stage filter has the SN ratio The original signal can be restored more cleanly.

As described above, in the ultrasonic wave detecting apparatus according to the present invention, since the signal collecting tube 120 is formed in a conical shape having an inclined inner surface 122, It is possible to change.

If an abnormality signal is not received, it is judged that all of the distribution facilities on the electric pole as the inspection target area are normal and there is no defective portion.

Therefore, it is possible to omit the task of aiming and diagnosing each power distribution facility on the electric pole.

On the other hand, if an electric pole including an ultrasonic signal generated in a defective portion is found, the operator can confirm that at least one of the electric distribution equipments constituting the inspection object region is defective.

In this case, it is necessary to determine which of the power distribution facilities on the electric pole, in particular, which state of the distribution facility is defective.

Accordingly, the operator stops and departs the vehicle, moves toward the pole, and uses the aiming device to accurately target the inspection target area in which the ultrasonic signal is received by the signal collecting pipe 120, specifically to one power distribution facility .

In a case where the inspection object area by the signal collecting pipe 120, that is, the ultrasound signal collecting area, becomes a single power distribution facility, the signal collecting pipe 120 receives ultrasonic signals generated from a single power distribution facility , The operator can determine which one of the distribution facilities is defective and the type of defective spot from the ultrasonic signal received while changing the object.

One end of the clamp rod 362 passes through the guide plate 364 and is connected to the clamp cylinder 360. The guide plate 364 is integrally fixed to a distal end surface of the actuating member 350, do.

Therefore, the guide plate 364 serves as a kind of fixed support plate for closely fixing the power distribution line when the power supply line at the point where the clamp rod 362 breaks is drawn.

A motor moving cylinder 370 is fixed to the other side of the second link piece 330 which is opposite to the lamp cylinder 360. A motor rod 372 is connected to the motor moving cylinder 370, A motor 374 is fixed to an end of the motor rod 372 and a circular knife 376 is fixed to the motor 374.

Therefore, when the motor moving cylinder 370 is moved back and forth in a state where the circular knife 376 is rotating, it is possible to cut a power line at a failed point by using the circular knife 376.

The circular knife 376 or the like should be installed on the inner surface facing each other on the pair of operating members 350 and the clamp rod 362 or the like should be installed on the outer surface of the operating member 350.

That way, you can grasp the power distribution line and cut it inside while tightly holding it. In other words, since the power distribution line is cut inside the pair of clamp rods 362, the power distribution line is still held by the clamp rod 363 even after the power distribution line is cut.

15, a heating wire (not shown) is embedded in the bent inner surface of the clamp rod 362, and the clamp rod 362 and the first lead wire SLR1 are connected to each other. Then, the first lead wire SLR1 The sliding bar 280 and the rectangular fixing barrel 270 are passed through the cylinder housing 290, the sliding bar 280 and the rectangular fixing barrel 270 in a state of being insulated and then passed across the part of the rectangular fixing barrel 270, And the switch 410 is connected to the switch 410.

Similarly, the second lead line SLR2 is connected to the switch 410 in the same manner, and the switch 410 is controlled to be on / off controlled by a controller installed in the cab 220. [

In this case, a heat wire is embedded to bypass the high-strength and to be energized, the heat wire is heated to dissolve the sheath of the power distribution line L, and then the clamp rod 362 is pulled once again to connect the power line L and the clamp rod 362) is energized so as to eliminate the problem that heat may be generated due to the increase in resistance when inducing local contact by using a needle or the like. Such bypass is not performed for a long period of time, There is no big problem.

In this case, the connecting portion between the clamp rod 362 and the clamp cylinder 360 is preferably insulated.
