Description

Technical Field

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

[0002] The arcing test of a high-voltage power supply is an important means for safety and performance evaluation, aiming 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. Through the arcing test, the safety and performance of the high-voltage power supply in various application fields can be effectively ensured, potential failures and accidents can be prevented, and the safety of the equipment and personnel can be guaranteed.

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

[0004] In the prior art, a manual method is generally adopted, that is, R & D personnel or workers hold the positive and negative electrodes of the high-voltage power supply and slowly approach until an arcing phenomenon occurs. However, the manual operation has low precision and cannot precisely control the electrode gap and arcing intensity, resulting in poor repeatability of the test results. The manual method is difficult to meet the requirements of frequent and rapid aging tests in the large-scale production of high-voltage power supply products, leading to low test efficiency and even potential safety hazards. Summary of the Invention

[0016] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0017] As Figure 1 - Figure 2As shown in the figure, it is a structural diagram of an arc test device provided by an embodiment of the present invention, including: a fixing member 1 for installing a first electrode terminal 4 and a plurality of second electrode terminals 5, and the first electrode terminal 4 and the second electrode terminals 5 are used to form an arc.

[0019] In the embodiment of the present invention, preferably, the arc test device is mainly used to test the arcs at different distances between the positive terminal and the negative terminal, accurately control the distance between the electrodes and conduct arc testing on the electrostatic precipitator high-voltage power supply. Since the electrostatic precipitator high-voltage power supply requires a stable high-voltage output, it is necessary to verify its anti-interference and reliability through arc testing. By adjusting the distance between the first electrode terminal 4 and the second electrode terminals 5 in the output of the stable high-voltage power supply, the arc strength formed between the first electrode terminal 4 and the second electrode terminals 5 at different distances can be obtained, thereby testing the relationship between the arc strength and the distance.

By controlling the contact distance between the negative terminal and the positive terminal and the movement speed between the negative terminal or the positive terminal through the driving component 2, arcs with different intensities and durations can be generated under different test conditions, avoiding poor repeatability of test results, thereby testing the electrical performance and reliability of the high-voltage power supply. The adjustable arc time and intensity facilitate the device to be applicable to different high-voltage power supply products, and the fixing member 1 is used to install the first electrode terminal 4, and the driving component 2 is used to drive the movement of the first electrode terminal 4, avoiding direct contact of personnel with the high-voltage part and reducing potential safety hazards.
