Description
Technical field
The utility model belongs to electric system technical field of nondestructive testing, and especially a kind of porcelain bushing ultrasonic wave detects with climbing ripple group probe.
Background technology
Insulator is the vitals of electrical network and power plant electricity equipment, due to design, the manufacture, installation, maintenance maintenance reason such as improper, and is in operation and is influenced by the adverse circumstances, easily cause failure fracture, jeopardize the safe operation of electrical network.Therefore, strengthen the effective detection to the in-service insulator of electrical network and quality assessment, to guaranteeing that the safe and reliable economical operation of electrical network is most important.Effective detection method at present for insulator is supercritical ultrasonics technology, but the ultrasound examination of insulator, without unified technical standard, makes a large amount of defects detect effectively and timely at present.
When ultrasonic creeping wave (also known as surperficial compressional wave, compressional wave etc. of creeping) refers to that ultrasonic longitudinal wave incides in second medium with first critical angle from first medium, a kind of inhomogeneous wave produced in second medium.Because most of energy during this wave traveling mainly concentrates in the lower certain limit in surface, thus there is higher detection sensitivity to the defect on nearly surface.And insensitive to surface of the work situation, be suitable for detecting shaggy workpiece.Due to the fracture of insulator in running have more than 95% be all in flange port 30mm to the first porcelain along between, and this section of major part that will detect be all flange, cement coated lower invisible, simultaneously in order to make insulator can not deviate from from flange and cement during mucilage binding, usual insulator all can process on surface, insulator surface is made to have certain roughness, certain impact can be brought to common detection method, and adopt and climb ripple detection technique because it is by the less character of surface roughness affect, better effect can be obtained.Because the external diameter of insulator is different, therefore need the probe that making one group of cambered surface is different, probe is better contacted with insulator outer wall, reduces coupling loss.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of porcelain bushing ultrasonic wave to detect with climbing ripple group probe.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of porcelain bushing ultrasonic wave detects with climbing ripple group probe, comprise column probing shell, in the inside of housing, from the middle part of bottom arc contact surface, be shaped with sound insulationg board enclosure interior compartition being become bilateral symmetry straight up, be sound penetrating wedge in the bottom of the right side that sound insulationg board is separated out or leftward space, left and right sides sound penetrating wedge upper surface is to median rise, on the upper surface of left and right sides sound penetrating wedge, all bonding is fixed with piezoelectric chip, damping block is fixedly mounted with above piezoelectric chip, the cable that piezoelectric chip both sides, left and right are drawn, respectively be packed in the transmitting socket of surface of shell and receive socket and be connected.
And the angle between the upper surface of described sound penetrating wedge and level is 27 degree.
And, described in climb ripple group probe be six one group, six probe bottom arc contact surfaces radius-of-curvature be respectively 60mm, 80mm, 100mm, 120mm, 150mm and 250mm.
Advantage of the present utility model and good effect are:
The utility model can complete the launching and receiving of climbing ripple signal, and probe is better with insulator coupling condition.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the detection position view of the utility model product when insulator detects.
Embodiment
Implement to be further described to the utility model below in conjunction with accompanying drawing, following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of porcelain bushing ultrasonic wave detects with climbing ripple group probe, as shown in Figure 1, comprise column probing shell 1, in the inside of housing, from the middle part of bottom arc contact surface 9, be shaped with the sound insulationg board 7 enclosure interior compartition being become bilateral symmetry straight up, be sound penetrating wedge 8 in the bottom of the right side that sound insulationg board is separated out or leftward space, left and right sides sound penetrating wedge is to median rise, on the upper surface of left and right sides sound penetrating wedge, all bonding is fixed with piezoelectric chip 6, damping block 5 is fixedly mounted with above piezoelectric chip, the cable 4 that piezoelectric chip both sides, left and right are drawn, respectively be packed in the transmitting socket 2 of surface of shell and receive socket 3 and be connected.
In concrete enforcement of the present utility model, described sound penetrating wedge is that organic glass makes, and wedge angle is the first critical angle of climbing ripple, and the angle namely between the upper surface of sound penetrating wedge and level is 27 degree.
In concrete enforcement of the present utility model, for meeting the outside specification of various in-service insulator, probe is made to be coupled good with insulator surface, described climb ripple group probe be six one group, the radius-of-curvature of six probe bottom arc contact surfaces is respectively 60mm, 80mm, 100mm, 120mm, 150mm and 250mm, can meet the detection of various in-service insulator.
In concrete enforcement of the present utility model, acting as of described damping block: the acoustic resistance Chinese People's Anti-Japanese Military and Political College, has very large damping action, has stronger sound absorption, and can absorb the sound wave of wafer backward launched in a large number, damping block and wafer are cast on together.
In concrete enforcement of the present utility model, acting as of described sound insulationg board: transmitting wafer and reception wafer are separated, prevents the signal mixing interference of radiating portion signal and receiving unit.
In concrete enforcement of the present utility model, described shell, material is aluminium alloy.
In concrete enforcement of the present utility model, as shown in Figure 2, porcelain sleeve flange is detection position from the position between the first full skirt, but this location gap is very narrow, probe can allow the scope of movement very little, and twin crystal parallel connection type creeping wave probe longitudinal size is little, not by the impact that probe moving range is little.But twin crystal parallel connection type probe lateral dimension is large, and the coupling effect for curved surface is poor, so the probe devising six group reduces the coupling loss of curved surface.
