I. Introduction
In numerous industrial and scientific research fields, on-site testing is of crucial importance for ensuring the normal operation of equipment, performance evaluation, and fault diagnosis. As a core component in many testing devices, the performance and portability of high-voltage power supplies directly affect the efficiency and quality of on-site testing work. The emergence of portable high-voltage power supplies has brought great convenience to on-site testing and expanded the application possibilities of high-voltage testing technologies in more scenarios.
II. Applications of Portable High-Voltage Power Supplies in Electrical Equipment Insulation Testing
The insulation performance of electrical equipment is a key factor in ensuring its safe and stable operation. In on-site testing, it is necessary to regularly test the insulation conditions of various electrical equipment such as transformers, cables, and insulators. Portable high-voltage power supplies can provide a stable high-voltage output to assess the performance of insulating materials through insulation resistance testing, withstand voltage testing, and other methods. For example, during insulation resistance testing, the portable high-voltage power supply applies a certain DC high voltage to the insulated part of the tested equipment, and the insulation resistance value is calculated based on the magnitude of the current flowing through the insulation. Compared with traditional fixed high-voltage power supplies, portable high-voltage power supplies can be conveniently moved to the installation site of the equipment. There is no need to disassemble the equipment and transport it to the laboratory for testing, which greatly saves time and labor costs. Meanwhile, their precise voltage control functions can meet the testing requirements of equipment with different voltage levels, effectively detect minor defects in the insulation, and prevent equipment failures in advance, thus improving the reliability of the power system.
III. Applications in Electrostatic Field Simulation
In some scientific research and engineering fields, such as electron beam processing, electrostatic precipitation, and electromagnetic compatibility testing, it is necessary to simulate and study electrostatic fields. Portable high-voltage power supplies can serve as the power supply part of electrostatic field generators. By adjusting the output voltage, electrostatic fields with different intensities and distributions can be generated. During the on-site commissioning of electrostatic precipitation equipment, portable high-voltage power supplies can adjust the voltage of the electrostatic field according to the actual working conditions to optimize the dust removal efficiency. For electron beam processing equipment, precisely controlled high-voltage power supplies can ensure that the energy and focusing characteristics of the electron beam meet the processing requirements. Their portability enables the rapid establishment of electrostatic field simulation environments in different experimental sites or industrial sites, facilitating on-site observation and analysis of electrostatic field-related phenomena by researchers, and accelerating the progress of scientific research projects and the optimization of engineering technologies.
IV. Applications in High-Voltage Pulse Generation
High-voltage pulses are widely used in radar detection, pulsed power technology, and biomedical fields. Portable high-voltage power supplies, combined with circuit elements such as pulse-forming networks, can generate high-voltage pulses with specific waveforms and parameters on site. During the on-site maintenance and commissioning of radar systems, portable high-voltage pulse power supplies can simulate the pulse signals of radar transmitters to detect the response performance of receiving systems and promptly identify potential fault hazards. In the biomedical field, high-voltage pulses can be used in techniques such as cell electroporation. Portable high-voltage power supplies are convenient for conducting relevant experimental research in laboratories or clinical sites, providing powerful tool support for the development of biomedical research and treatment technologies. Their compact structures and portability enable high-voltage pulse-related testing and application work to be carried out even in special scenarios such as field operations and emergency rescue.
V. Advantages of Portable High-Voltage Power Supplies
