Description

Technical Field

[0001] The present invention relates to the technical field of ceramic piece pressure resistance testing, in particular to a ceramic piece pressure resistance testing device with automatic loading and unloading functions. Background Art

[0002] Ceramic sheets are core components commonly used in high-voltage equipment such as capacitors and varistors. Their function is to isolate high-voltage currents and prevent high-voltage currents from breaking down the equipment.

[0003] During the manufacturing process, ceramic sheets may produce tiny pores, cracks, etc., or impurities may fall into them during the sintering process, resulting in insufficient insulation performance of the ceramic sheets. If the insulation performance of the ceramic sheets is insufficient, it may cause short circuits, arc discharges, etc. in the equipment, and even cause the equipment to catch fire. Therefore, the ceramic sheets need to be subjected to voltage resistance tests to ensure their safety and stability in high-voltage environments.

[0004] Traditional ceramic wafer withstand voltage test equipment often requires manual loading and unloading of ceramic wafers, which is not only inefficient but also prone to errors. In addition, traditional test equipment requires the addition of insulating oil to perform withstand voltage testing, which will cause the product to be scrapped. In addition, when a breakdown occurs due to insulation problems of the test piece, traditional test equipment cannot cut off the high-voltage current in time, resulting in a large short-circuit current burning the fault point.
