Remote Visual Inspection(RVI) with industrial endoscopes to better restore defects and make effective decisions.
Endoscope detection is a visual detecting method for quality control of areas that human eyes can not observe directly, special areas such as vessels, pipe inner part of the non-detachable equipment, the inner surface of narrow gap, liquid surface etc.
As shown in Figure 1, the detection of the core components of the transformer; 2. Maintenance inspection after large oil-immersed transformers are energized
What can yateks Industrial Endoscopes help you detect?
Transformer oil has the characteristics of excellent insulation performance, low viscosity, good heat transfer performance, and low price. Therefore, most power transformers use transformer oil as insulation and cooling medium. As one of the important equipment in the power supply and distribution system of industrial and mining enterprises and civil buildings, distribution transformers have a great bearing on the quality problems, which directly affect people’s electricity safety.
In the manufacturing process of oil-immersed transformers, there may be a foreign matter left in the middle of the insulating material layer, and at the same time, transformer failure may occur due to welding problems such as cracking of the weld, resulting in leakage and the like.
Under normal circumstances, the system can be used for comprehensive internal inspection without the need to drain the transformer oil or arrange for the maintenance personnel to enter the interior for manual inspection, which reduces the burden on the staff and greatly improves the efficiency.
During the communication process between Yateks product application engineers and customers, it was found that during the inspection and maintenance of large oil-immersed transformers, the inspection port was at the top, and the equipment was repaired.
Because the transformer was filled with oil and the internal space was small, people could not go in and check. Moreover, the operating space is limited, so it is necessary to use an endoscope for detection.
The measured transformer equipment is 3 meters high. To see the situation far away. Yateks recommend the telephoto lens to the customer. At the same time, the qualitative rod support pipeline is required to reach a fixed viewing position.
Yateks Industrial Video Endoscope Insertion Pipe System is equipped with oil-resistant and anti-corrosion, can pass through the complex structure inside the transformer, as well as LED fiber light guiding system, and ultra-high-definition camera, which can provide clear even in the dark and oily conditions, image.
The biggest feature of P series industrial endoscope products is that it has 1 million pixels, the detection efficiency is particularly clear, 360-degree arbitrary rotation, directional measurement, lock fine adjustment function, very humanized design, convenient to carry, convenient operation, very suitable for the scene use.
In the field, the P series video endoscope probe is inserted between the transformer windings or between the winding and the iron core for observation and photographing.
The transformer winding deformation can be directionally measured, and the P endoscope’s directional locking fine adjustment function is used to accurately know which one The phase and which side of the winding are deformed, the shape, severity and specific part of the winding deformation.
The technicians of the factory said that they were all based on the transformer winding deformation electrical test. It is difficult to make accurate judgments on the slight state changes such as transformer winding strap breakage and block misalignment.
Now it’s easy to do with our P video endoscope. The internal conditions are very clear. The sensitivity and comprehensiveness of the test results are unmatched by any previous experimental method.
