Description

Technical Field

[0001] The invention belongs to the technical field of testing equipment, and in particular relates to an arc testing device. Background Art

[0002] Arc testing of high-voltage power supplies is an important means of safety and performance evaluation, which aims to detect whether arcing occurs during the operation of the power supply, so as to ensure the reliability of the equipment and the safety of the operators. Arc testing can effectively ensure the safety and performance of high-voltage power supplies in various application fields, prevent potential failures and accidents, and ensure the safety of equipment and personnel.

[0003] The high-voltage power supply for electrostatic precipitator needs to provide a stable and reliable high-voltage output, and during the design and production stages, arc testing is required to verify its anti-interference ability and long-term reliability. The arcing process will generate high temperature, high-frequency electromagnetic interference and strong unpredictable signals, which puts extremely high anti-interference requirements on the circuit design and electronic components of the product. Arcing requires a sufficiently high voltage (usually more than several thousand volts) between the electrodes to break through the insulating medium. If the distance between the electrodes is too large, an arc cannot be formed. If it is too small, spark discharge is likely to occur instead of a continuous arc, which is difficult to control accurately.

[0004] In the prior art, the manual method is generally used, that is, R&D personnel or workers hold the positive and negative electrodes of the high-voltage power supply and slowly approach them until an arc is formed. However, the manual operation has low precision and cannot accurately control the electrode gap and arc strength, resulting in poor repeatability of the test results. The manual method is difficult to adapt to the frequent and rapid aging test requirements in the large-scale production of high-voltage power supply products, which reduces test efficiency and even poses safety hazards. Summary of the invention

[0005] The purpose of the embodiment of the present invention is to provide an arc testing device, which aims to solve the problem of the manual method commonly used in the prior art, that is, the R&D personnel or workers hold the positive and negative electrodes of the high-voltage power supply and slowly approach them until an arc is formed. However, the manual operation has low precision and cannot accurately control the electrode gap and arc strength, resulting in poor repeatability of the test results. The manual method is difficult to adapt to the frequent and rapid aging test requirements in the large-scale production of high-voltage power supply products, which reduces the test efficiency and even poses safety hazards.

[0006] The embodiment of the present invention is implemented as follows: an arc testing device, the arc testing device comprising: A fixing member, the fixing member is used to install a first electrode terminal and a plurality of second electrode terminals, the first electrode terminal and the second electrode terminal are used to form an arc; A driving component is connected to the first electrode terminal, and is used to drive the first electrode terminal to move so as to adjust the distance between the first electrode terminal and the second electrode terminal to perform an arc test.

[0007] An arc testing device provided by an embodiment of the present invention comprises a fixing member for installing a first electrode terminal and a plurality of second electrode terminals, wherein the first electrode terminal and the second electrode terminals are used for arcing, and the first electrode terminal is driven to move by a driving component to adjust the spacing between the first electrode terminal and different second electrode terminals so as to perform multiple arc tests simultaneously. The first electrode terminal is driven by the driving component to control the gap between the electrode terminals and the arc intensity, thereby avoiding poor repeatability of the test results and allowing the first electrode terminal to be tested simultaneously with different second electrode terminals to improve the test efficiency. The first electrode terminal and the plurality of second electrode terminals are installed on the fixing member for testing, thereby avoiding safety hazards to personnel caused by manual methods.
