Description

Technical Field

[0001] This utility model belongs to the field of low inductance winding inter-turn impact test technology, and more specifically, it relates to a low inductance winding inter-turn impact tester with anti-interference function. Background Technology

[0002] In the production and maintenance of electrical equipment such as motors and transformers, the testing of the inter-turn insulation performance of low-inductance windings is crucial. Poor inter-turn insulation can lead to faults such as short circuits and localized overheating during operation, seriously affecting the performance, lifespan, and operational safety of the equipment. Therefore, conducting impact tests on the inter-turns of low-inductance windings to accurately detect their insulation condition is a key step in ensuring the quality of electrical equipment.

[0003] Traditional testing instruments have significant limitations in data acquisition. Many instruments have fixed acquisition positions and angles, lacking flexibility and unable to move back and forth. This fixed data acquisition method results in incomplete data, failing to comprehensively cover all key information of the winding during the inter-turn impact test, thus greatly reducing data accuracy. Due to the lack of comprehensive and accurate data support, it is difficult to draw accurate and reliable conclusions when evaluating the inter-turn insulation performance of low-inductance windings, making it difficult to meet the increasingly stringent and refined requirements for the quality inspection of electrical equipment.

[0035] The specific usage and function of this embodiment are as follows:

[0036] In this invention, the low-inductance winding to be tested is placed at a suitable position on the clamping platform 201. Then, the double-ended screw A202 is rotated, causing the two sets of clamping seats 203 to move in opposite directions, so that the four sets of clamping plates 204 clamp and fix the low-inductance winding to be tested through the protective pads 205. The alligator clamps 207 at the top of the connecting wires 206 are clamped on the corresponding test points of the winding to ensure a firm connection. The double-ended screw B501 is rotated, causing the two sets of adjusting plates 503 to rotate in opposite directions through the two sets of adjusting seats 502, so that the acquisition frame 505 moves the infrared thermal imaging probe 506 up and down, so that the infrared thermal imaging probe 506 reaches a suitable height.
