Introduction

1. The ultrasonic flaw Detector of high-Voltage pillar porcelain insulator can quickly and conveniently, without damage and accurately detect, locate, evaluate and diagnose a variety of defects (cracks, inclusions, porosity, etc.) in the workpiece such as porcelain bottles, porcelain columns, porcelain sleeves, insulators, etc. 

2. The ultrasonic flaw Detector of high-Voltage pillar porcelain insulator has high reliability and good stability, can collect and store data comprehensively and objectively, and process the collected data in real time or post-processing (such as printing data or issuing reports), analyze the signal in time and region, frequency domain or image, reduce the influence of human factors, and improve the reliability and stability of retrieval. 

3. According to the characteristics and flaw detection requirements of porcelain bottles, porcelain columns, porcelain sleeves, insulators and other insulators in the power industry, special flaw detection software is added to enhance the emission intensity and improve the accuracy of flaw detection, which is more suitable for pillar porcelain insulator flaw detection.

4. For various types of pillar porcelain insulators and pillar material insulators with more than 95% fracture in the flange mouth between 75px and the first porcelain edge, a high-precision special probe for pillar porcelain insulator flaw detection (creeping wave probe. Small-angle longitudinal wave probe. 20 special probes such as dual element shear wave probes are available for users to choose; This special flaw detection probe is wear-resistant, high-precision, and resistant to electric field interference. Creeping wave detection method. The small-angle longitudinal wave detection method and the dual-crystal shear wave detection method are commonly used for ultrasonic testing of porcelain insulators and porcelain sleeves in service of power grids.

Pillar porcelain insulator and porcelain sleeve ultrasonic probe detection method

1. Straight probe longitudinal wave detection method

The longitudinal wave inspection method of straight probe is a method for pillar porcelain insulator manufacturers to detect the porcelain body before glue binding.

2. Oblique probe shear wave inspection method

3. Creeping wave detection method.

4. Small-angle longitudinal wave inspection method.

5. Dual crystal shear wave inspection method.

The detection of defects in the inner wall of the porcelain sleeve and the inner wall of the porcelain sleeve is commonly used by the double crystal shear wave detection method.

Application industry

It is widely used in the non-destructive testing and flaw detection function of power equipment such as porcelain bottles, porcelain columns, porcelain sleeves, insulators, power plant pressure vessels, pipelines, main equipment boxes, busbars, generator bearings, wire clamps, etc.

Transmit pulses

Pulse amplitude: low (300 volts), medium (500 volts), high (700 volts) graded selection, suitable for a wide range of probes

Pulse width: Continuously adjusted in the range of 25~5000ns (0.1MHz) to match probes of different frequencies

Probe damping: 50Ω, 100Ω, 200Ω, 400Ω optional, to meet the different requirements of sensitivity and resolution

Working mode: straight probe, oblique probe, dual element transducer, penetrating flaw detection

Peak memory: real-time retrieval of the highest defect wave, record the maximum defect value

Φ value calculation: the flaw detection of straight probe forgings automatically calculates and displays the equivalent size of the defect after finding the highest wave of the defect

Defect location: Real-time display of defect level, depth (vertical), and sound path position

Defect sizing: The defect equivalent dB value is displayed in real time

Defect qualitative: through the echo envelope waveform, it is convenient for manual experience judgment

DAC/AVG: Curves are automatically generated, sampling points are not limited, and compensation and correction can be made. The curve automatically floats with gain, expands with the sound path, and moves with the delay. AVG curves can be displayed for any aperture.

Crack altimetry: Automatically measure and calculate crack height by using endpoint diffraction waves.

Door Spread: Amplify echo details for easy echo analysis

Dynamic recording: Detect real-time dynamic recording waveforms, store and play back

Waveform Freezing: Freezes the waveform displayed on the screen for easy defect analysis

Plate Thickness Input: Enter the thickness of the workpiece, and the defect instrument of the secondary wave, the third wave and the multiple wave probe show the actual depth of the defect.

Weld Diagram: Displays the groove form of the weld and the direction of the sound beam, and visualizes the location of the defect.

Built-in standards: The flaw detection process standards of various industries can be freely set.

Gate alarm

Door position, door width and door height can be adjusted arbitrarily; B. The gate can be optionally set with incoming wave alarm or lost wave alarm; Alarm and shutdown of beeps and LED lights (LED lights are very effective in noisy environments) in the gate.

Data storage

100 sets of flaw detection parameter channels, which can pre-adjust the combined parameters of various probes and instruments, and freely set the flaw detection standards of various industries; It can store 50,000 flaw detection echo signals and parameters, realize storage, readout and transmission through USB interface.
