Description
Technical field
The utility model relates to field of electrical equipment, in particular to a kind of transmission line of electricity PRTV brushing quality detector.
Background technology
At present, whether the pollution flashover coating application quality of insulator qualified is all by visual check, there is various deficiency, such as inspector exist subjectivity erroneous judgement, cause check and accept efficiency and accuracy rate low, the needs in real work can not be met well.
Utility model content
Technical problem to be solved in the utility model is, provides a kind of transmission line of electricity PRTV brushing quality detector that can improve detection efficiency and accuracy rate.
Therefore, the technical solution of the utility model is as follows:
A kind of transmission line of electricity PRTV brushing quality detector, comprising:
Supersonic sounding device, comprise ultrasonic sensor and ultrasonic probe, described ultrasonic sensor sends ultrasound wave to detect the PRTV coating thickness of insulator surface and to send alarm signal when this thickness is less than preset value to alarm device by described ultrasonic probe;
Spectral analysis apparatus, is connected to described ultrasonic sensor, the reflection supersonic wave information received for utilizing described ultrasonic sensor to described PRTV coating carry out spectral analysis and and standard spectrum contrast;
Alarm device, is connected to described ultrasonic sensor, for giving the alarm when receiving described alarm signal.
In the utility model, utilize supersonic sounding device to detect PRTV coating thickness, the robotization detected can be realized, eliminate the subjectivity erroneous judgement of testing staff, and detection efficiency is higher.
Accompanying drawing explanation
Fig. 1 is the block diagram of the transmission line of electricity PRTV brushing quality detector according to the utility model embodiment.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.It should be noted that, when not conflicting, the feature in the embodiment of the application and embodiment can combine mutually.
As shown in Figure 1, according to the transmission line of electricity PRTV brushing quality detector of embodiment of the present utility model, comprising:
Supersonic sounding device 1, comprise ultrasonic sensor 11 and ultrasonic probe 12, described ultrasonic sensor 11 sends ultrasound wave to detect the PRTV coating thickness of insulator surface and to send alarm signal when this thickness is less than preset value to alarm device 3 by described ultrasonic probe 12;
Spectral analysis apparatus 2, is connected to described ultrasonic sensor 11, the reflection supersonic wave information received for utilizing described ultrasonic sensor 11 to described PRTV coating carry out spectral analysis and and standard spectrum contrast;
Alarm device 3, is connected to described ultrasonic sensor 11, for giving the alarm when receiving described alarm signal.
In the utility model, utilize supersonic sounding device 1 pair of PRTV coating thickness to detect, the robotization detected can be realized, eliminate the subjectivity erroneous judgement of testing staff, and detection efficiency is higher.
In the utility model, the index such as thickness, homogeneity of antifouling flush paint is detected by supersonic sounding device 1, spectral analysis is carried out at spectral analysis apparatus 2, contrast with the brushing Spectroscopic analysis results of standard, form brushing quality result, enumerate all kinds of brushing quality problem of brushing for inspector's reference; Give the alarm when coating thickness does not meet standard (being less than thickness preset value) and remind testing staff, thus mass defect can be found easily.
Concrete principle is: the feature that the sound wave penetration power utilizing ultrasonic detection device 1 to send is weak, wavelength is long, ultrasound wave reflects when encountering coating and insulator body, again because coating is different from bulk material, reflection required time is not identical yet, utilize propagation speed differential can calculate the time of propagating in coating, coating thickness can be calculated in the sound transmission speed being multiplied by coating, and carry out contrast with the standard value worked out in equipment and can show that whether PRTV coating qualified, this Cleaning Principle is general knowledge known in those skilled in the art, does not repeat them here.
Store the data according to national transmission line of electricity acceptance criteria PRTV coating thickness in ultrasonic sensor 11, and arrange alarm value, as found, detection thickness does not reach acceptance criteria and then gives the alarm.
Wherein, ultrasonic sensor 11 sends sound wave by ultrasonic probe 12 and penetrates on insulator surface PRTV, sound wave arrives and to carry out behind surface launching, completes its another Shu Shengbo of a periods of reflections and complete periods of reflections on porcelain insulator surface, and the speed that the difference of its twice periods of reflections is multiplied by PRTV coating Acoustic Wave Propagation again can draw the thickness of sample.Utilize ultrasonic probe 12 to make Pinhole-shaped to be convenient to wait exiguous space to measure to insulator elbow inside.
In sum, content of the present utility model is not limited in the above-described embodiment, and those skilled in the art can propose other embodiment within technological guidance's thought of the present utility model, but this embodiment is all included within scope of the present utility model.
