Endoscopes can detect what defects of the oil -soaking transformer?

When an oil -soaking transformer fails, an electronic video endoscope can be used to detect it. So the handheld endoscopy can detect which defects of the oil -soaked transformer? The editor of the micro vision will answer it for you.

1. Foreign body, welding testing

During the manufacturing process of oil -soaking transformers, foreign objects will be left between the insulation material layer. At the same time, it may also occur due to welding problems such as welding cracks. There is no need to discharge the transformer oil, which reduces the burden of testing personnel and greatly improves efficiency.

2. Wind detection

Portable industrial endoscope detection can confirm whether the transformer winding is deformed, shifted, whether the winding is damaged, whether the surface of the winding is clean, and whether there are dirt attachment.

3. fuel tank detection

The industrial endoscope can also enter the viewer directly from the oil pipe port to detect the fuel tank of the transformer. Through transformer oil to achieve internal insulation, the oil -pass blockage will cause short -circuit and plug -in discharge of winding, plugging and discharge. Therefore, in the operation and maintenance of the transformer, it is important to ensure that the smooth flow of the oil pipe is through.

4. Precision detection

The industrial endoscope enters the inside of the transformer from the gap between the transformer's oil pipe, lead holes, and pressure plates. Observe whether the winding of the winding and the distribution switch occurs due to overheating and the short -circuit impact of the current. Inspectors can also use the camera video function to record photos and videos inside the transformer, and give it to the relevant technicians to determine whether it needs to be disintegrated.

All in all, the industrial endoscope operation is simple, the test results are intuitive, and the judgment is accurate, which can improve the efficiency of inspection, save costs and time.
