Application of non-destructive testing for high-voltage power supply

High voltage power supply is an important equipment in non-destructive testing, which provides sufficient energy to drive the detection probe and ensure the quality of the detection signal. The application of high-voltage power supply in non-destructive testing is very extensive.

Ultrasonic testing

Ultrasonic testing is the most commonly used method in non-destructive testing. Ultrasonic waves can penetrate materials and detect internal defects such as cracks, notches, unwelded areas, pores, or inclusions through reflected waves. This is particularly important in the maintenance of high-pressure boilers and pipelines. High voltage power supply is used to drive ultrasonic probes to emit ultrasonic signals and receive reflected signals. High voltage power supply can provide sufficient energy to drive ultrasonic probes and ensure the quality of ultrasonic signals.

X-ray inspection

X-ray testing is an important method in non-destructive testing, which can image the internal structure of transformers, switches, and cables, identify welding defects, short circuits, or component positional deviations. It can also be used to detect internal defects of materials, such as cracks, notches, inclusions, etc. High voltage power supply is used to generate X-rays for X-ray inspection of materials. A high-voltage power supply can provide sufficient energy to generate X-rays and ensure their intensity and quality.

Magnetic particle testing

Magnetic particle testing is a non-destructive testing method used to detect defects on the surface of materials, such as cracks, pits, and peeling. When inspecting ferromagnetic components such as motors and transformers, powder magnetic testing methods can identify surface and near surface cracks and potential structural defects, avoiding faults and safety accidents, and ensuring the safety of equipment operation. High voltage power supply is used to generate magnetic fields for material testing. High voltage power supply can provide sufficient magnetic field strength to detect defects and ensure the accuracy of the detection results.

Electromagnetic testing

Electromagnetic testing is also a method in non-destructive testing. Combining high-voltage power supply with electromagnetic testing technology can evaluate the integrity of cable insulation layer and identify partial discharge problems in cables. Real time monitoring of equipment leakage current using electromagnetic detection technology to ensure the safety of equipment during operation, especially in medical equipment and high-voltage electrical appliances. High voltage power supply is used to generate electromagnetic fields for detecting materials. High voltage power supply can provide sufficient electromagnetic field strength to detect defects and ensure the accuracy of the detection results.

In non-destructive testing, high-frequency transformers are usually used for high-voltage power supplies, with the input voltage being the voltage of the AC power grid and the output voltage being high-voltage electricity. The output voltage of high-voltage power supply is usually several thousand volts to tens of thousands of volts to meet the requirements of different detection methods. The high energy, high output, high stability, and controllability of high-voltage power supplies provide the necessary energy and voltage for non-destructive testing, enabling those working equipment to operate normally. These non-destructive testing techniques, when combined with high-voltage power sources, can comprehensively evaluate the safety and reliability of equipment and materials, and are widely used in industries such as power, aviation, automotive, and medical.
